Postback not updating bound listbox indian dating and chating

Auto Post Back is set to true and page_load event fires. Thanks for the link Anand, that was a good article on update panels.

I was pretty sure that wasn't the issue but just to test I removed the nested update panel and the issue still exists, the event does not fire. The event does fire for another dropdownlist in the exact same modalpopup but that is bound to an objectdatasource rather than being bound in code. Hey Vincent, I don't need to set the onselectedindexchanged property on the control as the vb handler has the Handles clause at the end of it.

When I click different rows in the listbox the control changes the ID of the row depending on what I click. However my textbox tells me that I still have Row 5 (LBox. When I click different rows in the listbox the controlchanges the ID of the row depending on what I click.

One thing I'm doing is setting the .selected(i) property of the list box to true. Selected(i) = True 'this changes the highlited value in the list box End If Next By the way this is a single select list box.only select one thing. One thing I'm doing is setting the .selected(i) property of the listbox to true.

Face palm moment, but lesson learned - no 2 list items should ever have the same value if you want to do a postback when the selected index changes.

I also created a control on a form bound to that list box. I also created a control on a form bound to thatlist box.

Make sure you don't populate the Gridview in the Page_Load as it will fire before the Selected Index Changed.

If you do, the row on the Gridview, your dropdown is on will be reloaded and hence won't technically be there anymore by the time it needs to fire the Selected Index Changed method.

There are unique values in the dropdownlist and autopostback is set to true. More info: It didn't have anything to do with binding to an objectdatasource rather than in code.

I tried binding to an object datasource and I still get the same results - the event does not fire.

If I set append Data Bound Items=true and insert a listitem, the Selected Index Changed event does fire when it is supposed to.

So now I have to hardcode a listitem and then remove it programmatically and it works as expected without the extra listitem.

What I found was when the listitems were generated through a loop in the codebehind file and I didn't explicitly set one to SELECTED, the Selected Index Changed event never fires.
