Form is closing instead of performing function when i press close button

Question

In my project I am using two forms dialogForm and mainForm .

In mainForm I am calling the instance of the dialogForm something like this:

mainForm_Closing Event

private void mainForm_FormClosing(object sender, FormClosingEventArgs e)
{
    dialogForm dg = new dialogForm();
    dg.Show();
}

But in the above code, the mainForm is closing when I press close button and showing the dialogForm instead of even showing the mainForm .

I know I am doing something wrong here.

PS: I edited my question very much. If someone were working with my code then here it is .

Answer 1

You are using dg.Show() instead of dg.ShowDialog() . ShowDialog() will wait for the child dialog box to close before continuing to execute the instructions in the parent dialog box.

Return a value from the dialogForm and check if it is yes or no, and depending on that close the parent box.
