c# - Is there a way to get hold of the cancel event of the dialog boxes -

Is there a way in C # winform to open the Cancel button or save the dialog box?

It depends on what you can change You do not edit the behavior of ShowDialog You can only return the result and take appropriate action. There is a sealed class, which means that you can not inherit it and behave override. If you really need control over when openphiledialog is shown, then you will need to create your own form to handle the necessary behavior.
