How to: Perform Custom Actions when End-Users Click Navigator Buttons

• Oct 25, 2019

The following sample code handles the NavigatorBase.ButtonClick event to confirm with the user before deleting a record. A warning message box is shown each time a user presses the Remove button. The user can then click the Yes button to remove the current record or alternatively the No button to cancel deletion of the record.

C#

using DevExpress.XtraEditors;

private void dataNavigator1_ButtonClick(object sender, NavigatorButtonClickEventArgs e) {
    if (e.Button.ButtonType == NavigatorButtonType.Remove)
        if (MessageBox.Show("Do you really want to delete the record?", "Warning", 
          MessageBoxButtons.YesNo, MessageBoxIcon.Warning) == DialogResult.No)
            e.Handled = true;
}

VB.NET

Imports DevExpress.XtraEditors

Private Sub DataNavigator1_ButtonClick(ByVal sender As Object, _
  ByVal e As DevExpress.XtraEditors.NavigatorButtonClickEventArgs) _
  Handles DataNavigator1.ButtonClick
    If e.Button.ButtonType = NavigatorButtonType.Remove Then
        If MessageBox.Show("Do you really want to delete the record?", "Warning", _
          MessageBoxButtons.YesNo, MessageBoxIcon.Warning) = DialogResult.No Then
            e.Handled = True
        End If
    End If
End Sub
