                                  This example isn't showing any of the code-behind.

                                • Hello,

                                  I tried to open the example on my side and it displays the code behind for all versions, both VB.NET and C#. See the video. Try to reload the page by pressing Ctrl+F5 and check the example again. If the problem persists, specify your browser family and version.

                                  This example is what i was looking for.
                                  there is one interesting part missing:
                                  ShowNewButton="True" for the DetailRow

                                  i wonder how can that be implemented

                                  Regarding this tutorial, how I am able to show a message popup if some of the input data is invalid? 

                                  I have already created a popup and I want to do something like:

                                  protected void grid_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e) { var text= myTextBox.Text; if (string.IsNullOrEmpty(text)) { MyMessageBox.Show(textNummer); e.Cancel = true; } else { grid.CancelEdit(); e.Cancel = true; } }
                                  The problem is that the popup is not shown if there is 
                                  e.Cancel = true;
                                  Otherwise I get an exception if I don't set e.Cancel = true.
