How to close a form in UserControl

Question

I created a UserControl with the buttons Save, Close and Cancel. I want to close the form without saving on the Cancel button, prompt a message to save on the Close button and Save without closing on the Save button. Normally, I would have used this.Close() on the Cancel button, but the UserControl doesn't have such an option. So I guess I have to set a property for that.

Scrolling down the "Questions that may already have your answer" section, I came across this question: How to close a ChildWindow from an UserControl button loaded inside it? I used the following C# code:

private void btnCancel_Click(object sender, EventArgs e)
{
    ProjectInfo infoScreen = (ProjectInfo)this.Parent;
    infoScreen.Close();
}

This does the job for one screen, but I wonder if I have to apply this code for all the screen I have? I think there should be a more efficient way. So my question is: Do I need to apply this code for every form I have, or is there another (more efficient) way?

Answer 1

you can use

((Form)this.TopLevelControl).Close();
