WPF datagrid - Scrollbar performance issue

$
0
0

I have entity class which is having nearly 50 Properties. My data grid has 35 columns ( The columns 25/35 template columns and rest of the columns are cell template).

Some of the scenarios we will get maximum 11 k records not more than that. For testing purpose I have loaded 40 records only. However Vertical scrolling is fairly poor bottom to top or top to bottom.

Sometimes it is stuck up but I don’t know what is the issue. 

If you are using EnableRowVirtualization =false or Scrollviewer.cancontentscroll =false then it is moving very fast because the records has already been instantiated in the load time but it would not help for loading 8k records. I wonder if anyone has noticed this, or if they have any suggestions that might help for resolving my performance issues?
