How to know the details of calculated ActualWidth/ActualHeight

We were working on a WPF application project, and the 'about 1px problem' puzzled us a lot.

Finally, we guess maybe the problem about Width and ActualWidth.

For instance, we set Border width to 160px, and the actual width would be 160.4px.

Any method can help to find the details of the added 0.4px?

Solution

  • Try using tools like "WPF Inspector" or Snopp. This might help to detect problems at runtime.
