I've been trying to get the Filter Template on the grid to work with a RadComboBox, but have not been successful. I'm binding to a dataset which is a little different than the example at Filter Template Example. The dropdown seems to load correctly the first time, but then when I make a selection it fails. I'm guessing it's in the client code because it never gets back to the .

I'm getting the error:

Selection out of range
Parameter name: value

Below is my code:

private void refreshCombos()

{

AdminServiceClient adminProxy = new AdminServiceClient();

DataSet ds = adminProxy.GetUniqueAuditTypeCode(rgAudits.MasterTableView.FilterExpression.ToString());

RadComboBox rcb = new RadComboBox();

foreach (GridFilteringItem item in rgAudits.MasterTableView.GetItems(GridItemType.FilteringItem))

{

rcb = (RadComboBox)item.FindControl("rcbAuditTypes");

}

rcb.DataTextField = "AuditDescription";

rcb.DataValueField = "AuditTypeCode";

rcb.DataSource = ds;

rcb.DataBind();

//rgAudits.MasterTableView.Rebind();

}

Note, in the example you have the rebind that I've commented out above. When I do this, my ComboBox comes out empty. If I leave it out, then I get the values in the Combo Box.

I'm having a secondary problem with the ComboBox itself. Sometimes, the text in the is huge, other times it's the right size. I have no idea what's causing this.

Thanks
Rodney
