I had a similar problem setting the RadGrid.DataSource to a Linq query. I'll tell you a few of the things I tried, and what I eventually had to move to.
First off, if
AllowCustomPaging = True
Then the default paging is overridden. Try setting either the AllowPaging to true, or AllowCustomPaging to true, but not both. Telerik controls are fickle! :)
I tried setting up paging inside of the MasterTableView as well, to no avail I also added AllowViewstate and made sure the control was linked to the RadAjaxManager
<telerik:AjaxSetting AjaxControlID="RadGrid1">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="RadGrid1" />
</UpdatedControls>
</telerik:AjaxSetting>
Neither worked for me, but give it a shot.
I eventually used a Listview and setup the templated columns for the data inside, and enabled paging and it all worked just fine. I know this isn't a direct answer, but maybe it will give you some new ideas.
I just realized that I had both AllowPaging="true" andAllowCustomPaging="true" in my grid. Removing one of these fixed the issue.
