RadGridView and RadDataPager with a lot of data...

[Fabiana]

Hello support!!

I have one question:

1) I was using RadTreeListView with loadOnDemand. Perfect for me, because in my database ( I am using WCF), I have 1.0000000000000000000000 of items, but with loadOnDemand, I was loading step by step... I loaded 100 items by step, after click in some node, I was loading more 100 items....

2) Now I am using RadGridView, with RadDataPager... And I will show just 100 items by page, as I was doing in RadTreeListView loadOnDemand.

3) But to show  correct pages numbers in RadDataPage, should  I set RadDataPage "Source property", with these 1.0000000000000000000000 of items ? 

4) Is there a way to configure RadDataPage page numbers with a total of items ( without set Source property) , but load by steps whem pageIndex is changing ?

Thanks!!

Hello,

 Indeed you can configure everything in the pager. You can check for example this demo for more info about how to page endless collection.

I saw this example, but isn´t what I want to do...

 I would like to  perform custom paging via WCF service. I have RadDataPager connected to RadGridView. I want to pass actual PageIndex and PageSize to my WCF service and this service should return only rows for actual page. But I need to be able to list through all the pages using RadDataPager ( appear, page 1, page 2....page 100000), but just load items in grid by page
Is it possible to set number of pages in RadDataPager programatically?

Hi,

Indeed you need custom IPagedCollectionView - you can check also the application attached to this blog post.
