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

This is my VB code in form load event

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

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...

I'm no familiar with VB. But for your combo box code you should have included something this which I notice you didn't post it so I assume you don't have it bind:
