Question

I have a user control nested in a repeater.
Inside my user control I have another repeater and in that I have a panel.

I am trying to override the LoadViewState event of my user control and dynamically add controls to the panel. I want to do it in the LoadViewState so that the dynamic controls get added before the viewstate gets loaded, so they retain their values after post backs.

For some reason the LoadViewState event on the user control (ascx) is not firing. Is there some way to force it to fire, or is there another method I could use? I have ruled out the user controls repeater databind event, because I need it to work even if data binding isn’t happening and I can’t do it on the repeaters item created event either because the child panel and inner html doesn’t exist yet.

LoadViewState isn’t the appropriate place for adding child controls. For dynamically adding controls within a user control, you’ll want to look at the CreateChildControls method.

It’s not firing a LoadViewState event because you need to save at least one value in the ViewState to have the event fire.
