Hello,
Our users have repeatedly expressed the desire to have their data displayed in such a fashion that allows them to sroll the entire page in the browser. We have found that the RadGridView, when not specifying a height, becomes virtually unusable, due to the initial time it takes to render, when binding to larger collections of data (400+ records). The memory keeps ticking up until it runs out and an exception is thrown.
I'm aware that if the gridview's container, or the gridview itself, doesn't have a height specified, it will assume an infinite height which is the cause of the performance degredation. Aside from having to lock down the gridview's height (or height of its container), is there any way to allow records in the RadGridView to scroll down the page in the browser without the memory going off the charts? Or is the ONLY solution to have scrollbars (on the grid) w/in scrollbars (on the browser)?
Thank you!
Eric

Hi Eric,
Indeed the grid measured with infinity height will cause performance and memory problems since all rows will be created and rendered - there will be no rows virtualization.
You will get the same behavior with standard Silverlight DataGrid as well.
