We have a requirement where a RadGridView contains 2 GridViewComboBoxColumn. The first is a GridViewComboBoxColumn of default values; the second is a GridViewComboBoxColumn where the itemssource depends on the value in the 1stcolumn. In other words, I have a select that returns a list of items froma WCF and then I need to bind and assign its value to the combobox in thecorresponding row
