Does anyone know if there is an easy way to get at the list of items in the grid that match the current filter? It seems that the "Items" collection only gives you the items that are currently in the view area. I would like to do something like select all the items that match the current filter in order to perform some operation on them. Thanks in advance!

Hello,

 Generally Items will give you exactly the filtered (and sorted) items however in case of paging (not sure if this your case?) these filtered items will be paged.

I was using the Items list to do something directly in the UI level. I was getting tripped up by a misunderstanding of row virtualization. The items list does work as expected. Thanks!

Hi,

I need have the full list of filtered items in a paged GridView (the filtered items of all the pages) , how I can do this? The items only give me the list of visible rows-items

Hi,

 Are you looking for your ItemsSource?

Hi,

In the ItemSource I have all the items, I need only the filtered items but of all the pages, now I resolve removing the paging, get all the items and reapply the paging but is not a very beautiful solution

Is there a way to do this without turning off row virtualization? I think the ItemsSource only gives you the visible items if you have RowVirtualization set to 'true'...

Hi Morgan McCollough,

 Actually ItemsSource is what you've assigned and this cannot be changed by RadGridView. You can use Items property of the grid - this will respect filtering, sorting, grouping, etc. 

Best wishes,

Thanks for the quick response. Yeah, you can ignore that last post. I wasn't really thinking about what I was saying :)

I think I was thinking about the behavior of the "Items" collection with RowVirtualization turned on or off. I think it was that with RowVirtualization turned on that collection only contained the items visible on the screen, but at this point I can't remember for sure. Just ignore me for now and I'll post again if I get to work with this again and have something more coherent to say :-)
