Hi,
Our users are complaining about flickering when we remove columns from the grid at run time. I was thinking on making column Collapsed when user remove it instead. My question is if collapsing/hiding column still makes it resource consumer on view layer. I mean when we remove the column obviously all sort or UI refresh things go away for that column. My concern is if collapsing column the grid still maintains refresh data between source and view layer.
Thanks

Hello,
Can you clarify the question ".. if collapsing column the grid still maintains refresh data between source and view layer"? Are asking if the grid refreshes, in case some changes made to a data while the column is collapsed?
Thank you,Sam
Yes. I mean if let say I create grid with 100 columns and then collapse them all except 5. Obviously refreshing 100 columns grid is much pricy than 5 columns one. Would I have any overhead refreshing 5 columns grid with 95 collapsed comparing with grid of 5 columns only?
When the columns are hidden, it is only hidden from the view - but when they are collapsed, the CellValuePresenters are not generated. So if you have 95 column collapsed out of 100, you are better off then 95 columns hidden out of 100.
Let me know if you have any questions.
