Thread: Editing the Red X Control Button....

Hi,

I've stuck some simple code in my form cancel / ok buttons that disables any predecesing forms, and then enables them and brings them to the front once they are required again.

Is there any way to replicate this code in the Red X control button? I don't want to remove the whole controlbox as I'd like to keep minimise / maximise functionality.

Thanks.

If I understand you correctly, you want the X button to do something and then not close the application? You need to use the OnFormClosing event, which you can place anywhere in your form class:

Code:

protected override void OnFormClosing(FormClosingEventArgs e)
{
    // put your custom code here



    e.Cancel = true; // prevent form closure

    base.OnFormClosing(e);
}

Here's an example, where if you click the X button it shows a dialog asking you to confirm you wish to exit:

Code:

protected override void OnFormClosing(FormClosingEventArgs e)
{
    DialogResult result = MessageBox.Show("Are you sure you want to quit?", "Exit?", MessageBoxButtons.OKCancel);

    if (result != DialogResult.OK)
        e.Cancel = true;
    else
        base.OnFormClosing(e);
}

Great stuff.

Thanks.
