Custom Paging

Is it possible with Telerik MVC Grids to customize the pager similar to how grouping works?

So for instance I want to look at all of Student A's records and I don't care about how many rows will be returned.

Then I want to use the pager to look at all of Student B's records.

Is such a thing even possible? :)

Hi All,

I am using RadAjaxManager, RadPanelBar andRadGrid in my user control.

Issue:

1. Click on Webpart and click on "Add new record" in Grid from "FirstTabl" tab at first without clicking on any tab.
Add Mode and Edit Mode working fine as expected. Showing and populating all control(RadEditor, RadPanel etc.) from the grid properly.
It works fine.

2. Click on Webpart and then click on any other tab, then click on click on "Add new record". from Grid
Add Mode and Edit Mode behaves weird. Data not getting populating properly.

Controls inside RadGrid and AjaxManager not initializing properly.
Error: 0x800a138f - JavaScript runtime error: Unable to get property '_preInitialize' of undefined or null reference

After follow the #1 step and then if you work with any Tab its working fine.

Can anyone please help me how resolve this issue ? Why this is happing with TAB and Grid with Ajaxmanager.

Thanks,

Harish Patil
