Execute simple Logic without “locking” the UI

Question

I have a dialog with some txb\'s and a button. When this button is clicked I want to change the button\'s Text, disable the button, start some Logic and then close the Window.

Answer 1

Here's what I would do:

private async void ButtonClick() 
{
    //here, you're on the UI Thread
    button1.Enabled = false;

    await Task.Run(() => DoTheWork());

    //you're back on the UI Thread
    button1.Enabled = true;
}

private void DoTheWork() 
{
    //this will be executed on a different Thread
}
