hello,

I try actually to use the WebDropDown Control and want to raise the event: OnSelectionChanged but i am still getting  "__doPostBack is not defined" .....

    <igl:WebDropDown ID="WebDorpdown"
        EnablePaging="false"
        Width="200px"
        DropDownAnimationType="EaseOut"
        PageSize="10"
        OnSelectionChanged="WebDorpdown_SelectionChanged"
        TextField="value"
        DisplayMode="DropDownList"
        ValueField="key" runat="server">
        <ClientEvents />
        <AutoPostBackFlags SelectionChanged="On" />
    </igl:WebDropDown>
    <cc1:IGMvcScriptManager ID="sm" runat="server" />  

Code Behind:

            WebDorpdown.SelectionChanged +=WebDorpdown_SelectionChanged; in page_load

        protected void WebDorpdown_SelectionChanged(object sender, DropDownSelectionChangedEventArgs e)        { .....  }

any idea or solution?? thanks
