Hi Dimitri,
Try setting the StyleInfo.CellType property of the BoundColumn to "ComboBox" in a grid. Here is a code snippet.
GridBoundColumn EmpName = new GridBoundColumn();
EmpName.MappingName = "EmpName";
EmpName.HeaderText = "EmployeeName";
EmpName.StyleInfo.DataSource = GetComboTable();
//For setting the Combobox column with datasource as Datatable.
EmpName.StyleInfo.CellType = "ComboBox";
EmpName.StyleInfo.ValueMember = "ComboEmpName";
EmpName.StyleInfo.DisplayMember = "ComboEmpName";
this.gridDataBoundGrid1.GridBoundColumns.Add(EmpName);
Here is a modified sample.
