Hi,

      I have a datatable who's columnchanging event throws an error when the user enters in an invalid value. In the eventhandler, I check e.ProposedValue to make sure that the input is valid. The problem is, if the user tries to input a invalid number, I try to set e.ProposedValue to another default value before exiting the eventhander. But the ProposedValue doesn't show up in the grid. Can anybody help? Thanks!
