DialogResult could not be Found C#

Iam using this code.

DialogResult result = MessageBox.Show("Do you want to save changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
        if (result == DialogResult.Yes)
        {
            //...
        }
        else if (result == DialogResult.No)
        {
            //...
        }
        else
        {
            //...
        }

It throws me an error:

The type of namespace name 'DialogResult' could not be found (Are you missing a using directive or an essembly reference?)

How to fix it? Thank you.

The answer of a MessageBox is a MessageBoxResult, not DialogResult. (DialogResult is for older, like FileOpen Dialogs). Change "DialogResult" in your code to "MessageBoxResult", and it will rub.

You've tagged your question with asp.net and what you are trying to do is not possible in asp.net, you can choose the alternative of doing this by using Javascript, put the JS code in whatever event handler you are using. If you are using on some button click handler then put this one on your OnClientClick

OnClientClick="return confirm('Do you want to Save changes?');"

It will return true if user click on OK and false if clicks on Cancel.

Hope it helps.

Did you add the reference to System.Windows.Forms.dll to your project as well as import System.Windows.Forms in your source?
