GridViewDataColumn.AggregateFunctions doesn't run when component is loaded

[rodolpho carmo]

Hello Telerik Team!

First, thanks for the hard these controls are awesome!


My question is very simple, I guess, but I am not finding a straight answer.


I have rad grid that must be loaded already grouped by two fields.

I created it with

<

 

 

telerik:GroupDescriptor Member="OrderID" SortDirection="Ascending" DisplayContent

="Order">

 

 

and

<

 

 

telerik:GroupDescriptor Member="ProductID" SortDirection="Ascending" DisplayContent

="Order">

 

 

Everything with this part works ok, but the fact is, I need to sum some columns , count some others and show them at the group header (every group must have information of what's collapsed.

So you can imagine my grid like this

-ORDERID 1 (value : 50 quantity:12  <-- this is the aggregated info)
--PRODUCTID 678
----under order and product goes the data
----itemID 99 - value 20 quantity 8
----itemID 98 - value 30 quantity 4

-ORDERID 2 (value : 88 quantity: 4 <-- this is the aggregated info)
--PRODUCTID 677
----under order and product goes the data
----itemID 65 - value 77 quantity 3
----itemID 66 - value 11 quantity 1

 What is highlited in blod (I mean, the aggregated info) does not works when the component is first loaded. if I remove the grouping and do this manually (by going to the grid, grabbing the column and putting it into the group header) then it works. What am I missing when constructing this?

this is built using data columns aggregated functions.

 

 

 

<telerik:GridViewDataColumn.AggregateFunctions

>

 

 

 

 

 

<telerik:SumFunction Caption

="Quantity: " />

 

 

 

 

 

</telerik:GridViewDataColumn.AggregateFunctions

>

 

 

 

 

 

<telerik:GridViewDataColumn.AggregateFunctions

>

 

 

 

 

 

<telerik:SumFunction Caption

="Value: " />

 

 

 

 

 

</telerik:GridViewDataColumn.AggregateFunctions

>

 

 

Any suggestions?

Hi,

 Please use ColumnGroupDescriptor instead similar to this demo. You need to define the descriptor in code.
