HELP - filter woes

I've bound a datagrid to a dataset and subsequently trying to filter it using the following:

DsListProjs1.Tables("Table").DefaultView.RowFilter = "Client = '" & ddlClient.SelectedItem.Value & "'"

It comes back as an empty dataset - I checked the params are correct. Also,although I don't think I need to rebind I have tried that also!

Please help - I cannot figure it!!

Does the value have a number in it or text? Perhaps you mean to just filter on the text value of the selecteditem which would mean not including the value property.
