Hi Winan,

You need set the DataTextField and DataValueField properties for the DropDownList in your BindComboBox method. The DataTextField property is used to tell the DropDownList which column to display from your DataTable. The DataValueField is used to tell the DropDownList which column to save to another DataTable.

Me.ComboUserGroup.DataTextField = "MyDisplayField"
Me.ComboUserGroup.DataValueField = "MyFieldToSave"
