I have a GridView and it is binding a collection of objects that have around 30 fields/properties. It ends up with around 30 columns and 1000+ rows.
If I use a Template for some of the columns I notice that the grid becomes much slower. Are there any known issues or things I should look at in order to improve performance?
I have seen the demo with lots of columns and cells and if I don't style or use a Template my grid has relatively good performance. It's when I try to use a Template that it starts to get slow.
My Template is used to create a left or right border and also display visual cues (border, color, tooltip) under certain conditions. It's got about 8 border elements and 7 triggers. Normally only one border element is visible and the other visual cues are collapsed, but the grid still performs very slowly. However, even if I only use 1 border element in the template the grid becomes slower.
