I have several columns in a RadGridView control available for editing a percentage value. The "P" mask works great using a GridViewTextBoxColumn except I can't figure out how to set a limit on the number of digits a user can enter into a cell. There USED to be a MaxLength property to define the maximum length, but in the recent versions of the Rad Controls, this property has been removed ... no longer available. Can you tell me how I can maintain the nice formatting that the "P" mask provides (while editing) and still specify the maximum length of the string of digits the user is allowed to enter?
