[Solved] Aggregates order in the GroupHeaderRow

[Cyril]

Hi,

I read the following post :

http://www.telerik.com/community/forums/silverlight/gridview/group-description.aspx

The Converters approoach interest me a lot.
Unfortunately, I see that AggregateResult take an AggregateFunction in his constructor but the AggregateFunction is private...

My idea was to derive from AggregateFunction, then add a property 'Order'. Then I could do something like that :

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
    RadObservableCollection<AggregateResult> aggregates = value as RadObservableCollection<AggregateResult>;
    return aggregates.Cast(CustomAggregateResult).OrderBy(a=>a.AggregateFunction.Order);
}

With that, I have a robust way to order the aggregates in the group row header. 

So, why is the aggregate function is private, and could you please make the getter public?

Hi Cyril,

Would you clarify a bit why the approach illustrated in the forum thread is not appropriate for you?
