Well, technically I changed the DataSourceID that was already there in your sample.  I just changed it from an Access source to a SQL source. ;)  But you nailed it.  Removing the DataSourceID did the trick.  However, I did not want to use multiple columns but just a normal pulldown list and I accomplished it with the following configuration:

ASPX Markup

        <ISWebCombo:WebCombo 
            ID="WebCombo1" runat="server"
            Height="20px" Width="200px" >
        </ISWebCombo:WebCombo>

Codebehind:

combo.DataMember = "DefaultView";
combo.DataTextField = "reportSetName";
combo.DataValueField = "reportSetID";

combo.LayoutSettings.StatusBoxVisible = false;

combo.Columns.Add("reportSetName");
combo.Columns.Add("reportSetID");

DataView dv = (DataView)SqlDataSource1.Select(new DataSourceSelectArguments("reportSetID DESC"));

combo.PopulateUnboundData(dv,false);

Thanks Gordon.

Yes, I experience the post back with your sample.  I had to modify it to use a SQL data source, but that's it.  I've included my video and you can see it post back when I pull it down the first time.  I put a block of code in with a check for Page.IsPostBack to make it clear.

Gordon,

Although this works with an unbound data set.  It still posts back and that's what I don't want.  I need the combo box to populate with all the data items and NOT post back per my original description please.  Please unmark your response as an answer since it has not provided a solution to this issue.  Thank you.

I'm running into one more issue with the solution above.  Even though I can store the value in a hidden cell, when I finally post the page back, I cannot retrieve this value.  When I check the Page.Request.Params collection, only the combo box text is available and the value is not part of the fields posted back.  Any ideas on how to retrieve this value?  Thanks.

Of course I read this.  That's why I said what I said regarding no personal attacks or anything like that.  My statement is negative feedback towards the lack of helpful input from your end, so I don't understand why you would remove that.

You disrespect us, your customers, when you do not provide quality support and feedback and waste our time.  You should really head your own signature of "Providing the most excellent technical support for Intersoft customers. Your satisfaction is our success." because so far that hasn't been the case from my perspective.  And when I say "you" I mean InterSoft and not you personally.
