I'm Developing application using ASP.NET and VB.NET. It is used Ajax controls as well. I added dropdownlist (Standard controller) and databind to it. It is working well. But if i added Ajax combo box, it is not working. (It means data not filling to combobox) No any errors showing.

This is my ASP code

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
           <asp:ComboBox ID="ComboBox1" runat="server" AppendDataBoundItems="True"
       AutoCompleteMode="SuggestAppend" AutoPostBack="True" MaxLength="10">

This is my VB code in form load event

ComboBox1.DataSource = ds.Tables(0)
ComboBox1.DataValueField = "PT_ID"
ComboBox1.DataTextField = "PT_PartName"

In above code, dataset (defined as ds) has values. If i added Dropdownlist controller name instead of combobox1, data fill to the dropdownlist.

What's wrong with my code. no any errors are showing...

Other details.
