Public ReadOnly Property ColumnIndex As Integer
Property Value

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 )
{
if ( this->dataGridView1->Columns[ e->ColumnIndex ]->Name->Equals( "Release Date" ) )
{
if ( e != nullptr )
{
if ( e->Value != nullptr )
{
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;
}
}
}
}
}
// Handling CellParsing allows one to accept user input, then map it to a different
// internal representation.
private void dataGridView1_CellParsing(object sender, DataGridViewCellParsingEventArgs e)
{
if (this.dataGridView1.Columns[e.ColumnIndex].Name == "Release Date")
{
if (e != null)
{
if (e.Value != null)
{
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)
{
// Set to false in case another CellParsing handler
// wants to try to parse this DataGridViewCellParsingEventArgs instance.
e.ParsingApplied = false;
}
}
}
}
}
