We make quite a lot of use of the ValueList property on the WinGrid columns, ie, create a ValueList under DisplayLayout, populate it with valuelist items either statically at design time, or dynamically at run time, then set the value list property of a column to use that ValueList. The only problem is that the user can type anything they want into the cell with the value list, rather than having it limited to the contents of the ValueList, ie, it behaves like a combo set to DropDown rather then DropDownList. Is there a setting somewhere that I've missed to limit entry to what's in the ValueList?
