You need to change the cell editor to a masked edit, with the following:
‘ Create a masked editor.
Dim gridMaskedTextBox As GridMaskedTextBox = New GridMaskedTextBox
‘ set the mask to Upper Case chars
gridMaskedTextBox.Mask = “>”
‘ Set gridMaskedTextBox as the cell editor.
GridControl1.Columns(“ComponentCode”).CellEditor = gridMaskedTextBox
