Code is not loading the BAQCombo

That all looks fine, do you now if there are results in your QueryResult table?
Run
MessageBox.Show(dqa.QueryResults.Tables[“Results”].Rows.Count());
on line 279

i added the line and i get this resoult

Oh wai… I didn’t look at the code carefully…
You are assigning the columns to the grid… not the value. Try this

epiComboC2.DataSource = dqa.eryQuResults.Tables["Results"];
epiComboC2.ValueMember = "UD102A_ChildKey1";
epiComboC2.DisplayMember = "UD102A_Character01";

When i try that code, the combo box get grayed out. Should i use an Ultra ComboBox?

In the ComoBox Box properties set False to Retrieve on Activate.

Thanks so much it works gratefully
