When the Winfrom form is closed, refresh another form data binding control.

Set the closed form to form 1 and refresh form to Form 2,

1. The binding method in Form 2 is set to public, and the instance is obtained in single-instance mode (in this way, the instance is the same anywhere ).

2. register an event on Form 1 to form close event

This. FormClosed + = new FormClosedEventHandler (MakeThisDispose );

Private void MakeThisDispose (object o, EventArgs e)
{
This. Dispose ();
From2.getInstanse (). bindDataGridView (); // getInstanse () obtains the instance in singleton mode. This ensures that the operation is performed on the same instance object.
}

-- The result is that after Form 1 is closed, the data in the dview in Form 2 is refreshed, and the entire form is not refreshed.
