Question

I have tried what seems like everything – I’ve done similiar things many times before, but I’m obviously missing something.

I have a UserControl (ucA) – on ucA is a LinkButton that loads a different UserControl (ucB) programatically into a panel on ucA. ucB has TextBoxes, etc.

Why isn’t my control maintaining it’s state? ie: The textboxes are loosing thier value on postback – the control tree shows the name of the control and the Form values show the value (in trace.axd)

Here is the code for ucA (basically)

public int SlideCount {     get { return Convert.ToInt32(ViewState['SlideCount']); }     set { ViewState['SlideCount'] = value; } }  protected void LinkButton1_Click(object sender, EventArgs e) {     SlideCount += 1;     LoadSlideControls(); }  protected override void OnInit(EventArgs e) {     base.OnInit(e);     LoadSlideControls(); }  private void LoadSlideControls() {     this.pnlAnnouncementHolder.Controls.Clear();     for (int i = 0; i < SlideCount; i++)     {         this.pnlAnnouncementHolder.Controls.Add(             LoadControl('AnnouncementSlide.ascx'));     } } 

Heres a full example of what im trying to do: http://keithsblogs.com/ControlTest2.zip

The problem Vyrotek points out is that the control is added a little to late to the lifecycle on the click event – anyone have any ideas?
