Re: Determine base page calling web user control   (2 Views)
I have a page that has many web user controls (.ascx) and one is my left navigation. Every thing works great but now I have a situation where I need to use jQuery simpleModal code snippet in the .ascx file. I got it working but now the jQuery code does not work if I have it on my base page. So I thought if from my .ascx page I could detect that page was calling it that I could not load certain files.

What should be used?   (5 Views)
I really love all of these ASP.NET new methods for getting placed data such as command name and button click but as I am not converting project from asp classic to .NET I have noticed that after I am done with some the web site pages they're:
A) bigger in size
B) load slower then my old web site pages.after checking the trace info I have noticed that the viewstate is is pretty big, i use CommandName methods to deal with most of my postback.
should i stay with the old request.form request.querystring to boost performance

set button in usercontrol as defaultbutton in masterpages   (9 Views)
Hey
You mean you've a button that you need to be the default action, when the user hits enter on ur page, is that correct
If so, then you can use the DefaultButton Property:
http: weblogs.asp.net skoganti arch...20 231695.aspx
This is slightly trickier, in a master page scenario, as the form is defined in the master page, and the button is in a content page, however, this approach can still be used, it just has to be done in code snippet. Here's some info:
http: geekswithblogs.net AndrewSiem...ter-pages.aspx
Hope that helps
Gary
, Think I got it to work.Code:
Dim mPage As MasterPage
mPage = Page.Master
Dim mainform As HtmlForm = CType(mPage.FindControl("form1"), HtmlForm)
if (Not (mainform) Is Nothing) Then
mainform.DefaultButton = btnSearch.UniqueID
End If

adding user controls programatically   (6 Views)
I have a so so easy user control. It only has the word on it.
Code snippet:
hello
And I have the following code snippet in my Page_Load event of my Default.aspx.cs:
Code:
for (int i = 0; i
Where panAlerts is a panel control dropped on the web content form. I'm using MasterPages for this. If I debug and step by my code, it displays the code adding 10 alert Objects to my panel, but my panel stays blank. I check the source of the page and it displays an empty panel:
Code:
What am I doing wrong This does not make any sense. Why is it not able to add my user control I'd expect 10 "Hello"s in succession going down the page, instead I receive nothing. I have tried adding them to my form instead of the panel with out any improve results. Suggestions
, If you are adding it dynamically in codebehind, you should not want the . Try what brin told with out the reference.
The reason you have to do a LoadControl is because when you instantiate by classname, the lifecycle events of the control are not invoked.

Re: When to use querystring or just get the data again   (3 Views)
I have page A that navigates to page B. Both pages show a datum called Utilization. Utilization is retrieved on page A by calling a stored proc. So page A could pass Utilization to page B in a query string, or page B could call the stored proc too. I do not know that is the improve choice - passing less info around or saving a call to the database.

End user form wizard?   (3 Views)
I have a client that wants me to create a web site that allows registered members to create forms for their sub-members to fill out.
For instance allows say the owner of a bowling team wants to become a member of this site. He she wana's to add a registration form to their member page. This form of course could use text boxes drop downs, and more and more. Keep in mind this person has no solution how can i write code snippet. So the form builder needs to be so simple to use.
Is there a "pre-made" software package that I can use I do not really feel like re-inventing the wheel here if I do not have to.

MouseOver event on the Button in Asp.Net   (11 Views)
Good Day All
I have two image Buttons Like thisCode snippet:
Untitled Page







Now I want to do a mouse Over on WebimageButton1 and when i mouse is moved over that button it must disable WebimageButton1 and make WebimageButton2 Visible. and if the Focus is lost on Button WebimageButton2 it must hide button WebimageButton2
The Reason am Doing this Is that i want my user to Confirm with the second button. i was using a Menu Control inside a Multiview Control and the hovering isn't working meaning the Submenu does not appear. So i decided to display and hide Buttons to mimic that functionality.
If you've any Suggestion, pls Share
