Aggregate don't work anymore (Q2 2010->.NET4)

[Yves]

Hi,

We migrate all application to .NET4 C# and Telerik Q2 2010.
In a overview we use in the grid Aggregate="Sum"
With the old version of telerik Q3 2009 work this perfect.
Now with the new version I have the followin error:

Without the "Aggregate" work the gris perfect.
Any idee about this problem.

In advance thanks for your answer.

Hello Edwin,

I tried to reproduce the described issue, but to no avail. I am sending you a simple example, please check it out and let me know what differs in your case.
Looking forward for your reply.

All the best,

I'm experiencing this issue as well. I've got it working on another page, but with this new page, it didn't work.

I've been binding a datatable to the Grid through the NeedDataSource function. After specifying the data type for the column in the datatable, it works just fine. When the grid has to make assumptions as to the datatype, it doesn't appear to work. Also setting the datatype on the grid column doesn't resolve the issue, only when I set the data type of the column in the datatable.

I had resolved the issue by setting the data type of the column in the datatable before binding.
