Thank you for your quick response. I tried that and it still didn't work.
This is my code
|DataTable dt = new DataTable();
|dt = ds.Tables;
|cmbPrj.DisplayMember = "project";
|cmbPrj.ValueMember = "id";
|cmbPrj.DataSource = dt;
|cmbPrj.SelectedIndex = -1;
But this still shows up with the value returned from my databinding and not the blank text RadComboBoxItem I added through the control.
