If the XamGrid has more than 100,000 rows,I do the operation,such as sorting,filtering,grouping and so on,the IE will not respond for a long time. so how can I Improve efficiency? Thank you!
With 100,000 rows you really should be using some sort of data limiting methodology (paging / virtual collection / RIA).
While performance is critical to our controls, sorting 100,000 elements takes time.
