Don't think that would matter. Isn't it more logical to add this code to the
SelectIndexChanged event of the dropdownlist? We've included our test code,
it's C# but maybe it's of use anyway to you.

The PopulateDDLNoMobAccounts is called on page load!
Maybe I have to seperate to sub into two different sub??? What do you think!
Thanks

So when is PopulateDDLNoMobAccounts actually called? Because the code itself
works. We tried this in C#:
Control objControl = LoadControl("MyControl.ascx");
this.Controls.Add(objControl);

Can someone please tell my why the following doesn't work!
I don't get any errors on the page but when I choose a value from the
dropdownlist what is ment to happen is that a user control should be loaded
into
the page!
However I don't get any reaction what so ever!
Please see comments below!
Thanks
