Crash When Dragging Tiles

[Anthony]

Hi,

I am getting the following crash when trying to drag any tile. The strange thing is that I do not get the crash on my dev box but do once my app is released.

Any help would be appreciated.

Thanks

Hi,

I found the issue.

I added a DropShadowEffect to the Collapse icon on the Tile Header. On my VM with software rendering there was no issue. When I released the app to a PC the hardware rendering was crashing it.

The weird thing is that the DropShadowEffect on the Restore icon does not cause the crash.

Thanks
Anthony

Hi,

I have solved this now.

In the Maximize / Restore RadToggleButton style, I removed the default collapsed visibility of the Collapse grid. This gets set by the Visual States anyway.

Thanks
Anthony
