Question

In my main form, I am running this:

this.disableForm();
btnAbort.Enabled = true;

disableForm is an extension method for Form in my program defined as the following:

public static void disableForm(this Form f)
{
    foreach (Control c in f.Controls)
    {
        f.Enabled = false;
    }

    f.Cursor = Cursors.WaitCursor;
}

The problem is that the next command btnAbort.Enabled = true; doesn’t do anything.

It works if I put the code directly in the method and not call disableForm(). Why is this happening? Does it have something to do with threads?

Answer 1

This line:

f.Enabled = false;

Should be

c.Enabled = false;

The problem is because you are accidentally disabling your entire form.
