Hi everybody.  In my application I need to refresh my data frequently. This refresh is just a Rows.Clear() and Rows.Add() of items of my ItemSource that is a Table. In normal conditions, the process is Ok, but when I start to use AutoFilter option, my refresh process becomes very slow which is very noticeable when large data (2000 rows).

Why is that? How can I improve this performance?

Thanks for your help. 

Hi Darwin, 

Can you send us a self contained sample project that reproduces this behavior so that we investigate this in more detail?

You can send it to support@xceed.com, please include a reference to this forum post in your email.
