aggregatefunction and child grid

[invivo]

Hi,

First of all, sorry for my english ...
I just want to know if it's possible to have aggregate function for a child grid (hierarchy) as we can have with the grouping grid
(like the example Grouping aggregates)

thanks

Hello invivo,

To achieve your goal you need to modify <telerik:RadGridView.HierarchyChildTemplate> as shown in the following code snippet:

<telerik:RadGridView.HierarchyChildTemplate>
  <DataTemplate>
       <telerik:GridViewDataControl>
               <telerik:GridViewDataControl.GroupDescriptions>
                      <data:RadGroupDescription PropertyName="Number">
                             <data:RadGroupDescription.AggregateFunctions>
                                <data:CountFunction FunctionName="TotalNumbers" SourceField="Number"
                                Caption="Total numbers:" />
                                <data:FirstFunction FunctionName="FirsNumber" SourceField="Number"
                                Caption="First number:" />
                             </data:RadGroupDescription.AggregateFunctions>
                      </data:RadGroupDescription>
               </telerik:GridViewDataControl.GroupDescriptions>
          </telerik:GridViewDataControl>
      </DataTemplate>
  </telerik:RadGridView.HierarchyChildTemplate>

Sample application is attached. Having other questions - do not hesitate to contact us again.

Thanks a lot for your answer.

But my project looks like your example FirstLook (GridView).
is it possible to have aggregate function for my child grid but without recreate a RadGroupDescription ?

thanks

Hi invivo,

Currently the aggregate funcations are part of your group description class and cannot be declared separately.

All the best,
