Hi Mark,

Since you don't explain that you use the same scenario as Mr. Ramarajan, I assume that you just got the same problem (result). I'm sorry if I wrong.

If you want to bind the WebCombo to datasource, it is not recommended to bind in PageLoad event, it would be better if you bind it in InitializeDataSource event. Below is the sample code you could use:

protected void WebCombo1_InitializeDataSource(object sender, DataSourceEventArgs e)
    {
        dsNorthwindTableAdapters.ProductsTableAdapter da = new dsNorthwindTableAdapters.ProductsTableAdapter();
        e.DataSource = da.GetData();
        WebCombo1.DataTextField = "ProductName";
        WebCombo1.DataValueField = "ProductID";
        WebCombo1.AdditionalSearchFields = "ProductName";
    }

But if you use the scenario similar with Mr. Ramarajan, could you please attach me a simple sample to investigate the issue? Because I could not replicate the issue.

Regards,

Julia
