How to get RadGridView items using paging in telerik?

Question

I'm using RadGridView and RadDataPager in my wpf project . The problem that when I have to get all items of GridView it return only items of the current page ( that are only 10 rows ) and it should returns all items that exist in all pages.

Example :

list = Gridview.Items.Cast<User>().ToList(); //

Output : I got only 10 elements which are in the first page

My Question is :

How To get all items in GridView ???

NB:

My question is duplicated How to get radlistview items if you use paging , but the OP asked for a solution for Asp.net not for WPF solution.

I have searched for the same property mentioned in the solution , but I didn't find it .

Answer 1

You get them from the RadDataPager itself.

So if you set the ItemsSource of your RadGridView to a RadDataPager like this:

<telerik:RadGridView ItemsSource="{Binding PagedSource, ElementName=radDataPager}" />
<telerik:RadDataPager x:Name="radDataPager" 
                      Source="{Binding Items}" 
                      PageSize="5" /> 

You should either get the items from the Source property of the RadDataPager control or from the source property (Items in this case) that is bound to it:

list = radDataPager.Source.OfType<User>().ToList();
