ASP.NET / C#: DropDownList SelectedIndexChanged in server control not firing

Question

I\'m creating a server control that basically binds two dropdown lists, one for country and one for state, and updates the state dropdown on the country\'s selectedindexchan

Answer 1

You need to set AutoPostBack to true for the Country DropDownList.

protected override void OnLoad(EventArgs e)
{
    // base stuff

    ddlCountries.AutoPostBack = true;

    // other stuff
}

Edit

I missed that you had done this. In that case you need to check that ViewState is enabled.
