GridView and DataPager select all problem

[Globanet]

Hello,

I have RadGridView working with DataPager. I encountered a problem when tried to select all items in RadGridView. To do this I am going through each page of DataPager and add items to GridView SelectedItems collection. It seems to work, but after that if I try to switch page or deselect any item - my selection is removed. 

What is right approach to do what I want?

Hi,

RadGridView may keep track only of selected items present in its ItemsSource . In paged scenario it knows about the items in the current page only . That is why any attempt  t add items from other pages to its selected items collection would appear unreliable.

Yes, I know how it works. My question is how can I get desired result, is there any other way to select all items?

Hello Globanet,

As mentioned previously, RadGridView is not aware of the items that will be displayed on the next page. What you can try is to handle the events fired on changing the pages and implement the logic you require there.
