In my application I have a Button. If the button is clicked as select against a database is executed and the result is shown in a ListView.
As the select is quite complex, it takes some time to retrieve the data.

When I click the Button, the Application-Window should be disabled until the data is loaded.
But when I set the IsEnabled-Property of the Window to false, the window gets disabled after the data is loaded.

I tried to disable the Window in an other thread with a BackgroundWorker. But then I get an exception that the window is already in use by another thread.

How can I disable the Window bevore it retrieves the data?

    You did the wrong thing in a background thread. You have to affect the UI from the UI thread, and your data loading should occur in a background thread.

    The simplest approach is to use a BackgroundWorker to load your data, store that data in a class-level variable, and when your background work is complete, the UI re-enables and loads the data from the class-level variable.
