group count in header client-side

[Christian]

Ajax 2010.3.1317.45

as mentioned in this article,
http://www.telerik.com/help/aspnet-ajax/grdperformcalculationsingroupheader.html

I would like to have calculation (only group "count") on Any column being grouped. is there any way to accomplish this client-side, the reason for asking is that i use

 

 

 

GroupLoadMode="Client"

 

and dont want to set up groupfields for all columns, can i achieve this type of count aggrigation independent from what column is being grouped, maybe trough javascript?

Hello Christian,

The referred article suggests customization of the GridGroupHeaderItem showing various information about the grouped item. Unfortunately there is no straightforward client-side API that gets access to this elements so one option is to access them through jQuery like that. Note that you also need to manually calculate the proper aggregate value (count, sum) on the client.

function pageLoad()
                {
                    var grid = $find('<%= RadGrid1.ClientID %>');
                    var groupHeaders = $telerik.$(grid.get_masterTableView().get_element()).find('tr[class="rgGroupHeader"]');
                    if (groupHeaders.length > 0)
                    {
                        for (var i = 0; i < groupHeaders.length; i++)
                        {
                            var groupHeadertext = $telerik.$(groupHeaders[0]).find('p')[0].innerHTML;
                            //modify text in some way
                        }

                    }

                }
