Updating the current window on demand

I have a WPF control TBStatus that is a TextBlock, with a hidden 'Please Wait...'.

What's the best way to actually update the screen after each delay? It waits the 10 seconds and puts up the control. I tried a Dispatcher and same thing. What's the trick?

TBStatus.Foreground = Brushes.Red;

for (i = 0; i < 5; i++)
{
TBStatus.Visibility = Visibility.Visible;
Thread.Sleep(1000);
TBStatus.Visibility = Visibility.Hidden;
Thread.Sleep(1000);
}
TBStatus.Visibility = Visibility.Visible;

I typically use a refresh if I want something to update right away especially if the next line(s) would put it to sleep or are going to be busy processing data. I assume that is still an option in WPF?

Set your control to visibility collapsed:

Code:

---

mycontrol.Visibility = Visibility.Collapsed;

---

then use a story board. after it completes use an event handler and set the visibility to visible:

Code:

---


private void storyboard1_complteted(sender event args e)
{
    mycontrol.Visibility = Visibility.Visible;
}

---

There is no Refresh option in WPF.

Just setting the Visibility doesn't work. It waits until the 10 seconds are completely up before executing.

I think a Dispatcher method is almost the only way to get it working, but haven't totally got it yet.
