The most straightforward approach is to have a read-only RadMaskedTextBox in the ItemTemplate of a GridTemplateColumn, and an editable RadMaskedTextBox in the EditItemTemplate.
The other option to go with would be to use a regular GridMaskedColumn, but to manually mask your data values after the grid is bound. You can use RadGrid's ItemDataBound event for that:
sender, GridItemEventArgs e)
GridDataItem item = (GridDataItem)e.Item;
originalValue = item[
//implement masking logic here and update originalValue to masked value
].Text = originalValue;
