DataGridView.UserDeletingRow Event

Note: This event is new in the .NET Framework version 2.0.

Occurs when the user deletes a row from the DataGridView control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public event DataGridViewRowCancelEventHandler UserDeletingRow
/** @event */
public void add_UserDeletingRow (DataGridViewRowCancelEventHandler value)

/** @event */
public void remove_UserDeletingRow (DataGridViewRowCancelEventHandler value)

JScript supports the use of events, but not the declaration of new ones.

This event can be canceled to prevent a row deletion from being completed.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use the UserDeletingRow event to cancel the deletion of rows from the DataGridView if the starting balance row is included in the selection.

private void DataGridView1_UserDeletingRow(object sender,
    DataGridViewRowCancelEventArgs e)
{
    DataGridViewRow startingBalanceRow = DataGridView1.Rows[0];

    // Check if the Starting Balance row is included in the selected rows
    if (DataGridView1.SelectedRows.Contains(startingBalanceRow))
    {
        // Do not allow the user to delete the Starting Balance row.
        if (e.Row.Equals(startingBalanceRow))
        {
            MessageBox.Show("Cannot delete Starting Balance row!");
        }

        // Cancel the deletion if the Starting Balance row is included.
        e.Cancel = true;
    }
}
