i want a cell in a virtual grid to be editable by a user but i want to enforce the following restriction ..
Any Number or a list of predefined harded string values.
for example, if the predefined values where:
AA, BB & CC
These would all be valid values for user input:
10, .01, 100, AA, BB, CC
Another other letter or character combination would not be valid or allowed..
thks,
ak
