RadGridView in RadDockManager & Virtualization

[Michele]

Hello,
I'm using an MVVM pattern in a WPF application with RadDocking ... I've got some RadGridView inside usercontrols and they perform poorly with horizontal and vertical scroll... I've searched this forum and the problem seems to be a missing height/width on the RadGridView... since I've defined in me Shell a 1024*768 width have I for each UserCotrol to specify a default width/height? how can I set it to the parent content?

I've also some master/detail gridview that uses a behavior to fill the child RadGrid...those performs worst... have I to specify an height/width as well?

Thanks

Paolo

Hi Paolo,

Indeed you are right that when the GridView is inside a panel(or a RowDetailsTemplate), it will be measured with infinity and therefore the performance will be not so good. If RadGridView is measured with infinity the virtualization turns off. 
 
As you have already read, when you set the height/width, then the GridView will not be measured with infinity. Also setting RadGridView.ColumnWidth to a specific width (like 100) will increase both horizontal & vertical scrolling performance. 

Yes, you have to set those properties for  the GridView that is in RowDetails as well.
