Checking if a dataset is empty

I use a session variable to store the data filled in three form pages registration. On every page I create a dataset with a table object in it and then I assign the dataset to the session.

If the user decides going back to the previous form page I want to refill all the form fields with the data stored in the session, now I am trying to do it thus on the second page: (in the case of user comes from the third page)

CODESub Page_Load(sender As Object, e As EventArgs)
If Not IsPostBack Then

Dim ds2 As DataSet
ds2 = CType(Session("UserData"), DataSet)
If Not isNothing(ds2.tables(0).rows(0)) then

name.Text() = ds2.Tables(0).rows(0).Item("companyName").ToString
state.SelectedValue = ds2.Tables(0).rows(0).Item("State").ToString
city.SelectedValue = ds2.Tables(0).rows(0).Item("city").ToString

End If

End If

End Sub
But I receive this error just when I come normally from the first page to the second:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Line 73: state.SelectedValue = ds2.Tables(0).rows(0).Item("State").ToString

I don t understand this error because the subroutine says that only set the values from the session to the form fields if the data exists in the dataset: 'If Not isNothing(ds2.tables(0).rows(0)) then'. And if I come from the first page the dataset of the second page it doesn t exists yet...

Somebody knows what is the problem

On the first form page:
CODESub userData(Sender As Object, e As EventArgs)

Dim ds As New DataSet()
Dim dt As New DataTable()

Dim row As DataRow
row = dt.NewRow()
row.Item("Mail") = mail.Text
row.Item("Password") = password.Text
row.Item("userType") = userType.SelectedItem.Value
row.Item("zipCode") = zip.Text

Session("UserData") = ds

End Sub
On the second form page:
CODESub userData(Sender As Object, e As EventArgs)

Dim ds2 As DataSet
ds2 = CType(Session("UserData"), DataSet)

Dim row As DataRow
row = ds2.Tables(0).Rows(0)
row.Item("companyName") = name.Text
row.Item("State") = state.SelectedItem.Value
row.Item("City") = city.SelectedItem.Value

Session("UserData") = ds2


End Sub
Thank you

uping Ajax Update Panel   (185 Views)
I have three panels on a page: panel_A has a gridView gv1 with PageSize = "5" OnRowCommand = "LoadCompanyInfo" OnPageIndexChanging="gridView_PageIndexChanging1" Panel_B has gridview gv2 with PageSize = "5" OnRowCommand = "SelectEmployee" OnPageIndexChanging="gridView_PageIndexChanging2" Panel_C has labels CompanyID, CompanyName, EFirst, ELast and EMiddle. Panel_A panel_B and panel_C are in an update panel. Each row in gv1 is a LinkButton, so if I click on a row, it runs a method 'LoadAccount' which updates the labels in panel_C and also populates the gridview on panel_B. This part is working fine, when I click on a row in gv1, it updates the labels text in Panel_C and populates gv2 in panel_B. I am having the following issues: 1.When I click on a row in gv2, it makes the labels text in panel_C blank and gv2 also becomes blank, shows EmptyDataText. I expect it to just update EFirst, ELast and EMiddle. in panel_A. 2. When I click on the next page no on gv1 it fires LoadCompanyInfo method first and then goes in the gridView_PageIndexChanging1 event. I expect it to go in the gridView_PageIndexChanging1 event only and show next page in gv1 and not in LoadCompanyInfo , because I am just clicking on page no 2 not row 2. 3. gv1 refreshes on a timer event OnTick = Timer_Tick, and it clears off data in panel_B and panel_C. I want it to just update panel_A. I guess I will have to set up nested Update panels to accomplish this. I would appreciate if I can get help on setting these nested update panels on this page to accomplish the above 3 issues. Thank you.

Ajax MaskedEditExtender not displaying mask   (283 Views)
Okay, this is really throwing me and making me feel crazy. I'm sure I'm missing something dumb. I'm building an account registration form, and I want to put a mask on the phone number textbox, i.e. XXX-XXX-XXXX. I'm using the AjaxToolkit MaskedEditExtender and MaskedEditValidator. The validator actually does display it's error message, but there is no mask on the textbox. I have the toolkit registered in the web.config, and everything else I'm using from it works fine. I did notice that I can't drag-and-drop the maskededitextender into the form, which seems odd: the maskededitvalidator dropped in fine. Here's the table cell that has the phone number controls: I'm really at a loss as to what's going on, and I'm beginning to wonder if it's an issue with the page or the toolkit assembly, or maybe just doesn't like me anymore.

GDI+ Bitmaps, potential canvas(es)   (167 Views)

Static class vs Session object   (201 Views)
Am I correct saying that with ASP.Net, a static class, is basically a single server object, that is active across sessionsMeaning that if I set a value of a static class, all sessions will read the same value. But that means that if one user's session sets this value again with something new, EVERYONE will read this new value, not the old one.What I'm getting at is that I'd like to use something along the lines of: CODEstring text = StaticClassName.SomeValue;I just think it's way cleaner than:CODEstring text = Session["SomeValue"].ToString();Particularly because I don't need the cast with a static method. But, I think the nature of a static class (as I described above) makes this impossible, as it will return 'server' values, instead of 'client' (read: session) variables.Any ideas/suggestions about this
Basic Update Question   (255 Views)
I am new to I am creating a .net page which helps update information in an ACCESS database. No I can't upgrade to SQL Server at this time. I have a page which I open a open a reader and populate information on a form. I want the users to be able update any of the information on the page. Some of the data contains text boxes which contain 255 characters. Since the page is populated using a query, I have to update the tables individually. I have one page I am using. I have one Sub to populate data and then was going to call another sub on the onclick update event. I have passed a few hidden text boxes to make sure I know which tables passed data from the query. Is the only way to update an Access database by using the ExecutNonQuery and creating an update query stringCODE "update table set x='" & txt.text & "' where x='"&hiddentxt.text&"''Also if I want to see if the text box has changed from the original value populated, do I have to store each value in a session variable and see if it has changed before I invoke the update query
Create rtf file and display on client.   (279 Views)
What I am trying to do is to read an rtf file, replace some text with text from a database (name and address etc), save it to a folder and display it in word on the user's pc. To display the file I am shelling to it using a couple of lines of javascript. The code that reads, modifies and writes the file saves the path to the file in a textbox. This I hoped the javascript could use.Doesn't work. I think that the javascript sub is running before the database related code so there is no path to shell to.Does that seem likely If so, how can I do this I've been struggling away for ages at it. the individual bits work, just the link from the created filename and the javascript on the browser is not working. , OK, I have found your code to do that.If I change from pdf to rtf how does the file end up in ms word I don't understand.

Encoding data securely   (307 Views)
i'm coming from a php background where everytime i posted a variable back to the server i would wrap in a function before passing into my sql statement. This allowed me do a replacement for html entities and also a mysql fix to avoid sql injections.With if i use parameters i avoid any sql injections but i still have problems with html entities.Say in the edit profile area of my site i have a formview which uses 2 way databinding and contains a textbox for the user's first name. Then say i wrap the value (when posted back) with Server.HtmlEncode before updating the value in the database. If the user entered
Best way of designing this code   (341 Views)
The problem ( done in .net1.1).Ive been asked to do some work on a site that uses a number of webservice calls.Currently, there is a web page that kicks off an asynch call to a Web service.The site then redirects to a results page, where it has some javascript that forces it to post back X seconds, where the code on PageLoad checks a database to see if the service has finished executing and has written the result set to the databaseI have been asked to take what is currently being used and extend it, so that on page 1 it makes multiple calls to the webservice, then redirects to page 2 To my mind the whole setup seems inefficient, so I want to propose some changes. Before I do, I need to check my thinking, and get it right in my own head.The simplest approach is to leave the pages as they are, and adding more network traffic (the 5 service calls, then the 5 * n calls to the database until the results are in)But one of the concerns is the amount of traffic that this will cause on the network, and the performance if there are a lot of people using this at the same time (Lots of postbacks triggering lots * 5 database calls)To make it smarter Im thinking of having a manager class that relates the sessionID to a callbackHandler class. When the webservice is complete I will then trigger the database call to pull back that portion of the results, and store that in a dataset in the object.I still get a postback every x seconds, but then all that is doing is forcing the page to rebind to the dataset to display the results, to my mind reducing the traffic to the database significantly.So, can anyone offer any critique of what Im planning to do, and secondly, is there a way I can trigger a page refresh / postback from the server, so I dont even need to have a javascript timer on the client (which seems dodgy to me, as if js is disabled, then the page will never show its results!)I know this may be a bit "moon on a stick", which is why Ive left the option of doing it the current way.K

I have a SQLAdapter & DataSet Object but for some reason when I select the Databind Property on the label to Bind it, it allows me to find the Table and Column but won't place it in the property for use. I know this sounds strange so I can clarify if need be..if anyone has any suggestions I would appreciate it. Someone told me that I must code some of it out prior to trying this. However, this is not a diffilcult task and I think Visual Studio does all this for you...

Application Hangs Up on Pocket PC Only   (222 Views)
I have an ASP .NET web application that is used to scan parts for orders. I have tested with both a Windows XP Professional workstation using IE and a Pocket PC using Pocket IE. Basically, the process is to enter 3 text fields, either by scanning or typing, then press the "Add" button. The added parts are stored in a cookie on the client and then displayed in a DataGrid on the same page. These accumulate until another button is clicked. After "Add" is clicked for the 68th part, Pocket IE just sits there with the Windows logo moving; it will not continue. I have run the app in debug, and nothing appears to happen on the server side once "Add" is clicked. The Page Init, Load, and PreRender are not executed, and the button click procedure is not executed. I have checked this with Debug and Trace statements, as well as setting breakpoints in the code. I have also tried doing a "Break " at the point the app hangs, and I get the message "There is no source code available for the current location." There is no problem if the exact same test data is used on a Windows XP machine; it can add more than 68 parts. The Pocket PCs have 64MB of memory, and are connecting to the network via a wireless connection. Any ideas of what I can check next to find the problem Is there a limitation on the amount of data a Pocket PC can post back to the server Or a cookie size limitation on Pocket PC
Single record update - need advice   (279 Views)
I'm learning at the moment to develop my new websites. Iv'e used traditional asp for a number of years. I did a course on .net a few weeks ago and covered things such as datagrids, datasets etc. Iv'e managed to create datagrids that edit/update/delete records, and have forms to add a new record to an table in MS SQL in .net. The one bit I'm missing is where I want to update a single record where its number of fields is to big to fit in a datagrid row and therefore needs displaying in a single I have a record withTitle of workshopDescriptionStart dateEnd dateLinkTutorCommentsetc...What I did in asp was pass the ID of the record to an asp form read the database with a 'SELECT * FROM table WHERE ID=" + Request.QueruString("ID") which poulated the fields with the existing data in this record, the user then alters what they want and the data is written back to the table (theres only one administrator doing this so I don't have to worry about locking records etc). Where I get stuck in .net is how do I populate the fields Datasets seem too much for what is essentially reading just a single record, as does a datagrid. Really I want a form with a set of text fields and submit button, and someway of binding a single record field value to each of these fieldsFrom looking on the web it seems using a datatable might be the solution, but we didn't cover this is the course and its unclear to me the best way to get a single record into a datatable and then 'bind' it to each of the controls.The lack of data on the web suggests to me that I might not be understanding the .net paradigm rather than implementing. What is the best way of dealing with updating single records where the number of fields/size of fields is too big to display in a datagrid.The database I'm using is MS SQL Serve
How many layers are best practice?   (478 Views)
I occasionaly, while being in a deep "flow" of programming, run into these mind-design-problems, which i seem to forget but today i wrote one down. Suppose you have an item class, an item collection class, a dataclass (which fills the collection class with items stored in a database or flat file) and an e.g. "weblog" classto fill a collection you could instantiate the collection class in the weblog class as well as instantiate the dataclass in the weblogclass and fill it in the weblog class. In this way the collection class does not have to have a method called "fillme", which could be called to fill the collection class.On the other hand if the collection class would have a method called fillme it would make the weblog class much more simple since you would simply have to call something like weblogitemcollection.fillme and it would be filled... nog direct access needed to a dataclass whatsoever but... the single classes would be not so reusable since this specific dataclass in the collection class would always be needed.So you would have always have a item.cs, collection.cs, data.cs and weblogs.cs but the way you would call each other and which methods to include in each of these classes, in other words, the relations they have would differ.Another way would be to include an extra class, something like collectiondata.cs which would enable collection.cs to call something generic in collectiondata.cs to call data.cs.Which is the best way according to best practices --
asp / javascript checkbox enable/disable issue   (180 Views)
I have a 4 sets of checkboxes and text boxes on an aspx page. The checkboxes are disabled by default but when the text box next to it has text entered into it, the checkbox is supposed to enable.The problem is, the value is changed when I step through it in the debugger but the page is not. (checkboxes stay disabled on the page, but the value of checkbox.disabled = false)If i REVERSE this, making the checkboxes enabled by default and then try to disable them when text is entered, it works fine.Any suggestionsmy code looks like:CODE//elemArray[6] has checkbox.ClientID valuedocument.forms[0][elemArray[6]].disabled = false

I am trying to bind this dropdown list to a column in the databaseadd_attribute.DataSource = ds.Tables[0];add_attribute.DataTextField = ds.Tables[0].Columns["ss_attribute_name_c"].ColumnName.ToString();add_attribute.DataValueField = ds.Tables[0].Columns["o_id"].ColumnName.ToString();add_attribute.DataBind();BUT I get the error that the add_attribute could not be found.

Problem turning of validator client side   (199 Views)
all,I am having trouble with a required validator. I have several validators on a page that are enabled or disabled depending on what is selected in a drop down box.To disable them client side, I use ValidatorEnable(ID, true/false). This works for all the validators I disable on the form.However, on the server-side when I perform a page.isValid it fails because one of this disabled validators is now considered not valid.I have having trouble figuring out why a disable validator returns isvalid = true client side and isvalid = false when it gets to the server side. I am not sure if posting any of my code will help or not
