下列程式碼範例說明此類型的用法。 此範例是How to： Implement Virtual Mode in the Windows Forms DataGridView Control中提供之較大範例的一部分。
void dataGridView1_UserDeletingRow( Object^ /*sender*/,
System::Windows::Forms::DataGridViewRowCancelEventArgs^ e )
{
if ( e->Row->Index < this->customers->Count )
{
// If the user has deleted an existing row, remove the
// corresponding Customer object from the data store.
this->customers->RemoveAt( e->Row->Index );
}
if ( e->Row->Index == this->rowInEdit )
{
// If the user has deleted a newly created row, release
// the corresponding Customer object.
this->rowInEdit = -1;
this->customerInEdit = nullptr;
}
}
C#
private void dataGridView1_UserDeletingRow(object sender,
System.Windows.Forms.DataGridViewRowCancelEventArgs e)
{
if (e.Row.Index < this.customers.Count)
{
// If the user has deleted an existing row, remove the
// corresponding Customer object from the data store.
this.customers.RemoveAt(e.Row.Index);
}
if (e.Row.Index == this.rowInEdit)
{
// If the user has deleted a newly created row, release
// the corresponding Customer object.
this.rowInEdit = -1;
this.customerInEdit = null;
}
}
Private Sub dataGridView1_UserDeletingRow(ByVal sender As Object, _
ByVal e As System.Windows.Forms.DataGridViewRowCancelEventArgs) _
Handles dataGridView1.UserDeletingRow
If e.Row.Index < Me.customers.Count Then
' If the user has deleted an existing row, remove the
' corresponding Customer object from the data store.
Me.customers.RemoveAt(e.Row.Index)
End If
If e.Row.Index = Me.rowInEdit Then
' If the user has deleted a newly created row, release
' the corresponding Customer object.
Me.rowInEdit = -1
Me.customerInEdit = Nothing
End If
End Sub
若要取消刪除事件處理常式中的資料 UserDeletingRow 列，請將 Cancel 屬性設定為 true 。
