I am using RadGrid which binds a stored procedure call to 1 DataSet.  The first column of the DataSet is "Supervisor" which I have set a grouping on.  All of the Supervisors are grouping correctly and works great.  However, I would like to add a Footer row to the bottom of each section of Supervisor Groupings.  Additionally, I would like to have a summary row for the entire RadGrid at the bottom.  I've added the appropriate  RadGrid.ShowFooter,  RadGrid.MasterTableView.ShowFooter  and  RadGrid.MasterTableView.ShowGroupFooter values to true.

Finally to my question.  For each Supervisor "group" section of data being returned from the stored procedure, I have the Footer summary row with custom calculations performed in the sproc itself.  At this point, all I want to do is display the results of that sproc as the Footer.  Unfortunately, the data is presumed to be part of the GridDataItems and not a GridFooterItem.  How do I configure the sproc and the RadGrid to presume the last row of each "group" is the Footer summary row?

Thanks in advance.

Hello Stacy,

You could set the Aggregate property of the column to Custom which inturn triggers the OnCustomAggregate event .Here the custom result(the stored procedure result,  in your case) can be set using the e.Result argument. You can use the demo below to get started with:
Footer Aggregates

In the demo, you can see that the footer value for the CustomerID column is set to the arguments.Result in the CustomAggregate event handler in the code-behind.

Hope this helps..
Princy.

Hi Princy,

Thanks for responding, I appreciate it!  :D  I don't think I explained myself well.  I do not want to call a secondary stored procedure to get the summary footer, it's already in my dataset.  In the example below, I have Grouping on the first column (Supervisor), 2 rows of agents, and the third row is "Totals" which is what I would like to act as a Footer..  The calculations that are in the Totals row is performed on the SQL side because they are custom from the backend.  e.g.

--------------------------------------------------------------------------------
Supervisor | Agent | Some Value 1 | Some Value 2
--------------------------------------------------------------------------------
John  | Bob  | 123    | 345
John  | Steve | 123    | 345
Totals  |   | 246    | 690
Stan  | Stacy | 234    | 456
Stan  | Clark | 234    | 456
Totals  |   | 468    | 912

So, the real question is, how do I make the RadGrid aware that the "Totals" rows are Footers?

Thanks, I appreciate your help!

I tried to attach an image but, I don't think it worked.  I don't see it anywhere on the post.

Hello Stacy,

Since you already have the data as a standard data item, you can hide this dataitem. and show all the relevant data in the footer of the grid, or the group footer of the group. The following article elaborates on the first option:

http://www.telerik.com/help/aspnet-ajax/grdtotalsingridfooters.html

For the second option, you can access all GridGroupGooter items, and setup the fields accordingly.
I hope these suggestions help.

Sincerely yours,
