improving performance in very big wpf grid

Question

Let' s say I have a grid which size is: [650, 540] in each cell there is a UIElement like a rectangle or an ellipse

The grid is filled at the beggining and never modified in the entire life of the program

as you can see it's placed inside a scrollviewer

the problem is that as it is the program is absolutely not usable because of its slowness

should i consider changing from WPF to another library or there is a way to make it faster? can you suggest something?

thank you in advance

Answer 1

Use bitmaps instead of shapes. WPF is drawing all the shape whenever you scroll.
