Examples

The following code example demonstrates using ColumnIndex to discover if the changed cell is in the date column.

// Handling CellParsing allows one to accept user input, then map it to a different
// internal representation.
void dataGridView1_CellParsing( Object^ /*sender*/, DataGridViewCellParsingEventArgs^ e )
{

         {
            try
            {
               // Map what the user typed into UTC.
               e->Value = DateTime::Parse( e->Value->ToString() ).ToUniversalTime();

               // Set the ParsingApplied property to 
               // Show the event is handled.
               e->ParsingApplied = true;
            }
            catch ( FormatException^ /*ex*/ ) 
            {
               // Set to false in case another CellParsing handler
               // wants to try to parse this DataGridViewCellParsingEventArgs instance.
               e->ParsingApplied = false;
            }
         }
      }
   }
