I am using c# WinForms. I have a save dialog box that pops up and a message box after that that says it was saved successfully.

I just realized that if a user clicks cancel, my message box still comes.

How do i tell when a user clicks the cancel button on a save dialog box and then do something when it is cancelled?

    Add the code to your question showing how you display the Save Dialog Box and when it displays the message box. – Black Frog Sep 05 '14 at 20:15

Use DialogResult

if (form.ShowDialog() == DialogResult.Cancel)
{
    //user cancelled out
}

For SaveFileDialog:

SaveFileDialog saveFileDialog = new SaveFileDialog();
if (saveFileDialog.ShowDialog() == DialogResult.OK)
{
    MessageBox.Show("your Message");
}

A save dialog box after closing has the DialogResult property set to what happens. In your case:

if (mySaveDialog.DialogResult == DialogResult.OK) { /* show saved ok */ }

  • If I'm not mistaken you can also use DialogResult.Cancel – Andrew Grinder Sep 05 '14 at 20:15
  • Can confirm this is the best way - also me – jordan Sep 05 '14 at 20:15
  • It wouldn't let me do mySaveDialog.DialogResult but Habib's answer below worked great! (same thing really just a typo i think) Thank yo so much! – jAC Sep 05 '14 at 20:26

    @jordan.peoples, There is nothing wrong with my answer and also it was posted first (almost 30 seconds earlier). I am fine with the accept, just wanted to clarify – Habib Sep 05 '14 at 22:43

In case you are using WPF in a open file dialog, the better option I found is to store the selected file path (File.ReadAllText(filedialog.Filename) ) in a string and then check if its !== null wich means the user has a file selected. If the file path is null so the file is empty or the user just clicked on cancel button
