Hi
My Gridview began having performance issues when I added ColumnGroups feature , in my test case I have 3 level of Column Groups. the lowest level have 1000 column groups.,which means i have 1000 column to binding those columngroup. when i binding ColumnGroups in my GridView, it slow the performance a lot. If no column groups added, the loading time is around 2-3 sec. When I added the columnGroups the loading time is around 15-20 sec. please give some good advice to solve this issue.
version:silverlight 4_2012_1_0221
thanks,
guy

Hello Guy ,
It seems you have hit a known limitation with the current version of RadGridView. Column group headers are not virtualized and indeed with large amount of columns such performance degradation may be observed. We are doing our best to boost the performance with merged column headers so they can be used in scenarios with such large amounts of columns. The first optimizations will be included in our very next service pack ( within less than a month).
