Hi,

I've been working on minimizing the use of the ViewState in my asp.net
applications because of its overhead.  The problem I am having is that
I keep losing SelectedIndex in the DropDownLists.  I don't lose the
SelectedIndex when the ViewState is enabled, only when it is off.

I have a dropdownlist named countryCbo inside of a UserControl and
countryCbo's EnableViewState property is false.  In the OnInit()
method of the UserCountry it loads the country list from the database
and DataBinding it.

public void LoadCountryList() {
   // SQL Stuff ...

   this.countryCbo.DataTextField = "Name";
   this.countryCbo.DataValueField = "Code";
   this.countryCbo.DataSource = countries;
   this.countryCbo.DataBind();
}

// Doing this will load the countries but I lose the SelectedIndex on
a postback.
protected override void OnInit(EventArgs e) {
   LoadCountryList();
   base.OnInit(e);
}

// Doing this will load the countries but when a postback occurs I
lose all the countries and the list is empty.
protected override void OnInit(EventArgs e) {
   if (!Page.IsPostBack) {
      LoadCountryList();
   }
   base.OnInit(e);
}

I have read somewhere that the SelectedIndex resets back to -1 if a
databind occurs.  Would that be the case?
Could someone tell me how they have gotten their dropdownlists to work
without the ViewState being enabled?

Thank you!
