RadGridView GroupFooter Aggregates Don't Update Until You Leave the Row

There appears to be an issue with Aggregate Functions in GroupFooters not getting updated until you leave the row. I read this post about it that said it should be fixed but I am still not seeing the issue fixed in version 2012.1.215.

This is what I did. I created a new project and added a RadGridView. Added a couple of columns that are bound to my data. So that when I open the application it looks like screenshot1.

I then drag column Chud2 up into the Group Panel so it looks like screenshot2.

I then edit any field in column 1 and tab to column 2 and the Total: Aggregate for column 1 does not get updated as shown in screenshot3.

If I hit my Enter key or click to another row then the Total: Aggregate for column 1 gets updated as shown in screenshot4.

I have tried hooking up to the Grid's CellEditEnded event as recommended in other posts and calling the CalculateAggregates() method there but that does not solve the problem either.

My .xaml code is as follows:

<Window x:Class="RadControlsWpfApp6.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadGridView x:Name="radGridView"

AutoGenerateColumns="False"

ShowGroupFooters="True"

CellEditEnded="radGridView_CellEditEnded">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn x:Name="_colChud"

UniqueName="Chud"

DataMemberBinding="{Binding Chud}">

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:SumFunction Caption="Total: " />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn x:Name="_colChud2"

UniqueName="Chud2"

DataMemberBinding="{Binding Chud2}">

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:SumFunction Caption="Total: " />

</telerik:GridViewDataColumn.AggregateFunctions>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>

And my code behind is as follows:

namespace RadControlsWpfApp6

{

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

radGridView.ItemsSource = Data.GetData();

}

private void radGridView_CellEditEnded(object sender, Telerik.Windows.Controls.GridViewCellEditEndedEventArgs e)

{

radGridView.CalculateAggregates();

}

public class Data

{

private double _chud;

public double Chud

{

get { return _chud; }

set { _chud = value; }

}

private double _chud2;

public double Chud2

{

get { return _chud2; }

set { _chud2 = value; }

}

public static ObservableCollection<Data> GetData()

{

ObservableCollection<Data> data = new ObservableCollection<Data>();

Data d = new Data() { Chud = 1, Chud2 = 1 };

data.Add(d);

d = new Data() { Chud = 2, Chud2 = 1 };

data.Add(d);

d = new Data() { Chud = 3, Chud2 = 1 };

data.Add(d);

d = new Data() { Chud = 4, Chud2 = 1 };

data.Add(d);

return data;

}

Am I missing something that would make the Group Footers update their Aggregates when you tab out of a cell?

Thanks,
Chad

ClearCommand binding

I tried to bind ClearCommand with my own command, but the handling method never fires, instead it seems the original handler still fires and clears the input. Does binding works on ClearCommand?

Here is my view model code:

public DelegateCommand ClearCriteriaCommand { get; set; }

and setup:

ClearCriteriaCommand = new DelegateCommand(o => ClearCriteria());

here is the binding:

<RadMaskedTextInput Name="txtSearchField" Value="{Binding Path=SearchCriteria, Mode=TwoWay}" ClearCommand="{Binding Path=ClearCriteriaCommand}" AcceptsReturn="False" EmptyContent="Enter Search Term">

MaskedInput (Numeric, DateTime, Text, Currency)

Problem when defining a Border style in Office2013

Hello,
create a new WPF application, add references to Telerik.Windows.Controls and Telerik.Windows.Themes.Office2013.

Then, replace App.xaml with:

<Application

x:Class="WpfApplication1.App"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

StartupUri="MainWindow.xaml">

<Application.Resources>

<ResourceDictionary>

<ResourceDictionary.MergedDictionaries>

<ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/System.Windows.xaml"/>

<ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.xaml"/>

</ResourceDictionary.MergedDictionaries>

<Style x:Name="MyBorderStyle" TargetType="Border">

<Setter Property="BorderBrush" Value="Black" />

<Setter Property="BorderThickness" Value="1" />

</Style>

</ResourceDictionary>

</Application.Resources>

</Application>

Replace MainWindow.xaml with:

<Window

x:Class="WpfApplication1.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:tk="http://schemas.telerik.com/2008/xaml/presentation"

Title="MainWindow" Height="350" Width="525">

<tk:RadListBox Margin="10">

<tk:RadListBoxItem Content="One" />

<tk:RadListBoxItem Content="Two" />

<tk:RadListBoxItem Content="Three" />

</tk:RadListBox>

</Window>

Run the application: the list box items have a black border around them, as defined in the border style. But that's wrong because this is not a default style, so it should not be applied in this case.

RadPane events in 2013.3 1204

Hi, I'm using the latest 2013.3 1204 version and I noticed that the call order of the RadPane events has been changed.
In the previous versions, I suppose that the ActivePaneChanged event was first fired and then the Activated event, but in the latest version this order was changed. Am I right? I want to know if this change will be consistent in the upcoming versions as this will cause a substantial change in my application. Thanks!
