TPF: animated gif files are not being animated in high dpi mode

This problem is even reproducible in our Demo application >> Virtual Grid >> Web service example. You will notice that when you scroll to the bottom, the waiting indicator is not being animated when the DPI scaling is higher than 100%.

If you apply the same gif file in a PictureBox it gets animated when using 150% DPI scaling.

Hello, Dan, 

I would recommend you an easier solution. Simply set the RadControl.EnableImageDpiScaling property to false. Thus, only the image scaling will be disabled not the whole application. However, the spinning animation will be executed.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

I've modified the sample to produce a manual animation of the spinner icon.

I create a timer and loop through the view elements to update the image. 

If anyone has another approach that is more efficient, I'm keen to hear about it.

Thanks!

Dan.
