Question

I have a window with a grid in it. This window has a button, when this button is pressed, a modal dialog is shown.

code:

    private void Edit_Click6S(object sender, RoutedEventArgs e)
    {
        TextEditWindow editWindow = new TextEditWindow();
        editWindow.ShowDialog();
    }

When the user is finished with this dialog, the following code is called:

    Window.Close()

But the grid of the parent window is not updated. Is there a way to reinitialize the parent windows grid when the child dialog is closed? Is so, How?

Answer 1

Since dialogs block execution until they are closed, you can populate the grid directly after your ShowDialog() call:

private void Edit_Click6S(object sender, RoutedEventArgs e)
{
    TextEditWindow editWindow = new TextEditWindow();
    editWindow.ShowDialog();
    PopulateGrid();
}

Otherwise you can handle the dialog’s Closed event

editWindow.Closed += dialog_Closed;    

private void dialog_Closed(object sender, System.EventArgs e)
{
    PopulateGrid();
}
