Hi Telerik,

Firstly My Boss tells me we have support but unfortunately a couple of people have left and the support details have been lost - would you be able to tell me how to recover these details?


I have a RadGrid control where certain columns and the group footers and footers need to be recalculated based on cell input (Excel style)
The calculation is too complicated to be solely performed in Javascript so we have decided to partially update the grid using AJAX and are successfuly doing this in the RadGrid itemcreated event as per this article:


http://www.telerik.com/support/kb/aspnet-ajax/grid/ajaxifying-particular-controls-in-radgrid-template-column-with-ajax-manager.aspx

I am then using this javascript to initiate the ajax request :

 

ajaxManager.ajaxRequestWithTarget(sender.getAttribute('myUniqueId'true), 'true'); 

We want to know if it is at all possible to do the same with GroupFooters and Footers because at that point in the grid lifecyle there seems to be no way to reference the data that binds the template control Cell to its Group Footer and Footer.

Kind regards,

Ashley

Hi Ashley,

To your first question: You can ask the Telerik licence holder to add you as a developer. Then you should be able to open formal support tickets, etc.

You can see this online demo on how to display totals in the grid footer. However in order the data calculated in the group footers to be updated, you will need to update the database and rebind the grid.

Kind regards,
