Hi,
I have a custom user control for one of my columns. In that user control there a number of images depending on the state. When I am scrolling the grid there is definately a performance problem that causes the image to redraw behind the text on the same line. I am assuming this is because the image is being reloaded everytime the row is created/shown.
Is there a way that I can make the Images a static resource so that the same instances are shared for all of the rows?
Cheers,
Clint

Hi Clint Singer,
Unfortunately, since Image is UI element it cannot be added in more than one parent. As a result you cannot have shared UI elements between different parents.
However if your image sources are not resources of the application and need to be downloaded you can created dictionary to cache them.
You can also switch to Differed scrolling mode to improve scrolling experience.
If you have any other questions or issues do not hesitate to contact us.
Kind regards,
