How to do something if cancel button on save file dialog was clicked?

Question

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. – Accoutre

Answer 1

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 – Shiva

Can confirm this is the best way - also me – Tarkany

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! – Alcina

@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 – Jem

Answer 2

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");
}

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
