Hello,

I am working on the Data Virtualization feature of RadGridView in Silverlight. Whenever I use Shift+DownArrow to select multiple records in the grid, it selects the records upto the load size. As soon as next set of data loads into grid, the grid loses focus and I am unable to select more records using Shift+DownArrow. Similar issue happens when I use Page Up/Page Down to scroll the grid. I found a post similar to this issue but solution was not provided there : http://www.telerik.com/community/forums/silverlight/gridview/data-virtualization-issues.aspx

Please provide a solution or work around for the problem. I am using following sample code provided in Telerik Demos for Data Virtualization :
