I manage to create UserControls (.ascx pages) and i call them at the html coding, but I did not manage to display those UserControls from my vb sub
This is how I crate the UserContorls:
<%@ register tagprefix="aspx4devs" tagname="myheader" src="header.ascx" %>
this is how I Call it
<aspx4devs:myheader id="Myheader1" runat="server" NAME="Myheader1"></aspx4devs:myheader>
But I nead to Call it From a sub becaouse I use Code behind and ASP.NET with Visual Basic.NEt
if I stick a DropDownList in a TableCell (all server-side) and click it, it drops down
over the grid without enlarging the cell and distorting the table. How do I get a user control to do the same? I've tried using Code:
<div style="z-index : 400">
in
my UserControl.ascx and in the main page layout but without success.
How can I access a web.asp code behind class-on from a code behind calss-function in a loaded web usercontrol. A.aspx loads control B.ascx . A's classA.function A displays info to a label on A.aspx .
I want to call classA.functionA from control B's class B.function B so that when I click on a button located on control B, the on click event fires class B function B which then calls class A function A which displays the info.
I have a usercontrol that consists of a dropdownlist that is databound to a sqldatasource. It gets populated with a staff list.
I've setup properties that can be set for the usercontrol when it's accessed from an aspx page.
I then have an aspx page that has a formview on it that is databound to a sqldatasource.
On the edititemtemplate I bind to the dropdownlist usercontrol's SelectedValue property that I setup.
The bind works, but it seems only works for writing to the control. When I bring up the edit item template, it shows the properly selected value from the dropdownlist, but when I change that value and then hit save, the item I changed to on the usercontrol dropdownlist isn't grabbed and sent back to my server it seems.
On the ORIGINAL version of my page that consists of about 30 other bound controls, it would give me an error of "Cannot insert the value NULL into column 'blahblahblah', table 'Blah.dbo.Blah_tbl'; column does not allow nulls. UPDATE fails.
The statement has been terminated."
But when I rip almost everything out and just leave the company name textbox and the dropdownlist it doesn't return that error, but it still doesn't save my value. It posts back the page as if it had saved it, but no data is updated. Code:
