    If I use CellTemplate and then horizontally scroll so column isn't visible then scroll back I have a noticeable slowdown (jerk) in scrolling.

    If I replace this code with using DataMemberBinding without CellTemplate I don't see this problem.

    Any advice on how to fix this problem?

    (saw some old threads about it but not sure what's the resolution).

    Just to clarify slowdown happens when new column is about to be made visible.

    Hello Pavel,

    Generally speaking, custom CellTemplates do degrade the scrolling performance. How it will be affected depends also on what is defined within the CellTemplate. May I ask you to review the Tips and Tricks and Degraded Performance topics, as all suggestions for optimizing the overall performance of the control are listed there?

    Template is a text block with URL. Would be nice if it was a bit faster. Not sure what causes this lag. Templates don't slow down other controls as much (like list view).

    Hello Pavel,

    Can you please confirm that you have gone through all suggestions listed in the two articles to which I referred in my previous reply? Also, may I ask you to provide more details on your setup and the usage of the control, so I can try to replicate the problem locally?

    Thanks in advance for your cooperation.
