Viewstate and user control

[Hardy Wang]

Hi all,
I have a main ASPX page, and a control ASCX page, there is a Repeater
control in ASCX page, and several drop down boxes in main page. These drop
down boxes will trigger postback.
In the ASCX page, if I put code like
private void Page_Load(object sender, System.EventArgs e) {
if (! Page.IsPostBack) {
Data_Binding(); // to populate values in Repeater
}
}
Everytime when the page posts back because of drop down box selection
change, I loose all content in the Repeater. I enabled ViewState in ASCX and
Repeater control. If I let page to run Data_Binding() regardless of postback
status, then it is fine.
In my mind, Viewstate should remember what is for Repeater, I should not
need to commnet out the line if (! Page.IsPostBack) to make page to recreate
the Repeater everytime.

Any idea?

Thanks!

The only time I have seen this behavior is when the main page is loading
the control dynamically using LoadControl().
