DataGridView.UserDeletingRow Event

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)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

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. This example is part of a larger example available in the SelectionChanged event.

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;
    }
}
