Is there a way to accomplish loading data on demand with WPF GridView?
That means gridview should ask me how much DataItems to render to show an appropriate scrollbar.
Then when you scroll dataitems into view,  GridView fires an event, where in I can load only that data that is visible.
I not only need UI virtualization but rather data virtualization.
If not, does GridView support paging like asp.net Gridview?

Hi Uli,

Thanks for your interest in our RadGridView for WPF.

Still RadGridView for WPF does not support paging functionality out of the box. However it is in our To-Do list and it will be implemented in the RadGridView for Silverlight first.

Meanwhile you can accomplish your task quite easily. You can define the desired total number of items per page and the total page count.

Please follow the link to a blog post illustrating how to do this.

If you have any questions, please feel free to ask.
