Hi. I just updated to the latest internal build for Silverlight RadGrid, since this release should have the bug with the UI not being updated on recalculation. This seems to work fine until I add a ResultFormatString to the SumFunction, then the display of the sum gets messed up. Can you confirm if this is a bug in the component? I have attached the code I use and a image of how it looks when messed up.

I also tried using a IValueConverter on the binding on the TextBlock, instead of the ResultFormatString, with the same result.

<telerikGridView:GridViewDataColumn Header="Value"   
                                    UniqueName="CurrentValue"   
                                    DataMemberBinding="{Binding CurrentValue, Converter={StaticResource currentPriceConverter}}"   
                                    IsSortable="False" 
                                    MinWidth="100" 
                                    Width="Auto" 
                                    TextAlignment="Right" 
                                    HeaderTextAlignment="Right">  
    <telerikGridView:GridViewDataColumn.AggregateFunctions> 
        <data:SumFunction SourceField="CurrentValue" ResultFormatString="{}{0:c}" /> 
    </telerikGridView:GridViewDataColumn.AggregateFunctions> 
    <telerikGridView:GridViewDataColumn.Footer> 
        <GridView:AggregateResultsList ItemsSource="{Binding}">  
            <ItemsControl.ItemTemplate> 
                <DataTemplate> 
                    <TextBlock VerticalAlignment="Top" Text="{Binding FormattedValue}" HorizontalAlignment="Right" FontWeight="Bold"/>  
                </DataTemplate> 
            </ItemsControl.ItemTemplate> 
        </GridView:AggregateResultsList> 
    </telerikGridView:GridViewDataColumn.Footer> 
</telerikGridView:GridViewDataColumn>

Hi, thanks for the answer.

I attached the project you provided and it worked fine, so I checked a bit further. It seems like it is the theme that is messing it up.

Are there any changes to the themes that can mess this up? I tried to rebuild the themes using the new builds of the controls, but the aggregates still gets messed up. When I added the theme that's following the latest build it's working fine. Is it possible to get the source for the themes if there are any changes to them? We need to change a few of the colors on one of the themes to use it.

Thanks in advance.

Hi Reven,

Currently we are not shipping the Themes sources with our internal builds which is something we are considering of doing in the future. That being said I cannot provide you with the xaml for that particular build. On the flip side we are finalizing a Q3 Service Pack 1 which will be available early next week.

A part from the many fixes it will include the themes for all our controls.

Sincerely yours,

Hi, I am trying to create exactly this footer template but from c# code.
Unfortunately I do not understand what should be the ItemsSource for the binding of AggregateResultsList in C# code.
Mode precisely: I try to translate this in C#:   ItemsSource="{Binding}"

existing code behind:

           var gridColumn = this.GridView.Columns[3];
            var aggregateItems = new AggregateResultsList();
            var aggItemsSourceBinding = new Binding("ItemsSource")
                                            {
                                                Source = gridColumn
                                            };
            aggregateItems.SetBinding(ItemsControl.ItemsSourceProperty, aggItemsSourceBinding);
            aggregateItems.ItemTemplate = GridTotalsTemplate;

And item template is defined in Xaml:
 <DataTemplate x:Name="GridTotalsTemplate">
                            <TextBlock VerticalAlignment="Top"
                       Text="{Binding FormattedValue}" HorizontalAlignment="Right"/>
</DataTemplate>

Thank you

Hello Reven,

 

Why not use the approach demonstrated in your online "Totals" demo?
If you want to change the footer template at runtime you may reference the defined DataTemplate within a UserControl's Resource Collection and then set it to this column dynamically.
