Pinning rows when using VirtualQueryableCollectionView

[Dennis Tycho]

Hi,

I am experiencing a rather odd behavior, when i try to use the pin functionality on a gridview with datapager.

The gridview is bound to a VirtualQueryableCollectionView, which only load the relevant data based on the page shown. If I pin rows on page 1, all seems to be working fine. But when I pin a row on page 2 (Or above), Only the pinned row is shown at top, and the rest of the items are blank. When I unpin, all data are presented as expected.

I have reproduced the behavior in the attached project.

 

Am I missing something?

 

Best Regards

Hi Dennis,

I will check your case and let you know about my findings later today.

Hello Dennis,

This is a timing behavior that appears because the pager and the virtualized collection both have load on demand mechanisms. In order to resolve the issue on your side, you can set the Source property of the RadPager control after the initial loading of the VirtualQueryableCollectionView. You can see this approach shown in attached project.
