We have a grid which is loading programatically columns and it's datatemplate. The column might contain a label or a link or an Items control containing multiple links. The grid is using virtualization and contains couple of hundered records however there are two problems as far as the performance is concerned.
1. The memory footprint goes in increasing even by scrolling the grid up and down. We have seen it going from 6 MB to 150+ MB in a matter of minutes of scrolling.
2. The grid becomes extremly slow when styles are applied to it.
Turning Virtualization off fixes the ever increasing memory footprint.
Sidenote: We have also started getting a lot of errors descibed on this thread (http://www.telerik.com/community/forums/silverlight/gridview/system-nullreferenceexception-at-at-telerik-windows-controls-gridview-selectivescrollinggrid-layoutawarebindinghelperproxy.aspx). Can by chance that be a reason why the performance issues are also showing up ? This thread says that it has been fixed in the internal build. When do you plan to release that ?
