Very standard & basic chart mixing both line and candlestick series on same axes; is this possible in RadChartView? I've got a working solution in the old RadChart, but performance is dire and I've been trying to replicate similar functionality in RadChartView to benefit from improved performance.

The only "X" value I can find on OhlcDataPoint is category. Am I missing something obvious?

DateTimeCategoricalAxis is not an option as datapoints are non-uniform, and the line charts must have more granularity than the candlesticks on the x-axis.

GridVIewRow.DetailsVisibility does not work

We have the following GridView:

<telerik:RadGridView Grid.Row="2"  RowDetailsTemplate="{StaticResource FundRowDetails}"
                             RowDetailsVisibilityMode="Collapsed" 
                             Name="radGridViewFunds"
                             CanUserFreezeColumns="False"
							 AutoGenerateColumns="False" 
                             RowHeight="28" 
                             EnableColumnVirtualization="False"
						     ScrollMode="RealTime" 
                             RowIndicatorVisibility="Collapsed" 
                             IsSynchronizedWithCurrentItem="True" 
                             IsReadOnly="true"
                             LoadingRowDetails="RadGridViewFundsLoadingRowDetails" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" RowActivated="RadGridViewFundsRowActivated" >
                <telerik:RadGridView.Columns>

                    <telerik:GridViewDataColumn DataMemberBinding="{Binding ReturnSource, Mode=TwoWay, UpdateSourceTrigger=Default}" Header="Return Source" Width="100" />
                    <telerik:GridViewDataColumn DataMemberBinding="{Binding Auditor, Mode=TwoWay, UpdateSourceTrigger=Default}" Header="Auditor" Width="100" />
                    <telerik:GridViewDataColumn DataMemberBinding="{Binding StrategyGroupName, Mode=TwoWay, UpdateSourceTrigger=Default}" Header="Strategy Group Name" Width="100" />
                </telerik:RadGridView.Columns>
            </telerik:RadGridView>
In addition, there is a button that is used to add a new item to the gridview through the datasource.
After a new row is added, I would like to have the row expanded. Here is the code for that:

private void RadButtonNewClick(object sender, RoutedEventArgs e)
        {
            LogProcess("New button was clicked");
 
            ControlTabs.SelectedIndex = 0;
 
            checkShowAllFunds.IsChecked = true;
 
            var newFundPending = _fundList[0] != null && !_fundList[0].UpdateDtm.HasValue;
            if (newFundPending)
                return;
 
            textBoxFundNameCriteria.Text = string.Empty;
 
            LogProcess("Inserting blank fund into fund view data");
 
            var newFund = new vFund();
            _fundList.Insert(0, newFund);
 
            _newFund = newFund;
 
            LogProcess("Rebinding data");
            radGridViewFunds.ItemsSource = _fundList;
            radGridViewFunds.Rebind();
 
            radGridViewFunds.SelectedItem = newFund;
			radGridViewFunds.CurrentItem = newFund;
 
            var newRowGridItem = radGridViewFunds.ChildrenOfType<GridViewRow>().FirstOrDefault();
            if (newRowGridItem == null)
                return;
 
            radGridViewFunds.ScrollIntoView(newFund);
            radGridViewFunds.UpdateLayout();
			
            newRowGridItem.DetailsVisibility = Visibility.Visible;			
        }
However, The newRowGridItem.DetailsVisibility does not work, and the newly added row remains collapsed. How can I
Programmatically expand the new row?
Thanks.

How to retrieve the grid rows in the TreeListView

How do you get the collection of rows that have been added to the TreeListView? Currently our usage of the TreeListView is to display data elements that we have converted from an older version to a newer version. Many of the elements in the TreeListView may have errors or warnings associated with the translation. Sometimes we want to see these elements displayed in the TreeListView, and sometimes we only want to see the successful ones, and sometimes we want to extract these errors and warnings and put them in a list control, so extraction is needed. Thank you for any recommendations that you have.

GroupHeader and events

Hi,

I would like to rise an event when a user click on a TextBlock located in the group header of my ScheduleView. Here is my XAML :

            <telerik:RadScheduleView.GroupHeaderContentTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding FormattedName}" Grid.Column="1" FontWeight="Bold" Width="100" HorizontalAlignment="Left" VerticalAlignment="Center">
                            <i:Interaction.Triggers>
                                <i:EventTrigger EventName="MouseUp">
                                    <commands:EventToCommand Command="{Binding TestCommand}" />
                                </i:EventTrigger>
                            </i:Interaction.Triggers>
                    </TextBlock>
                </DataTemplate>
            </telerik:RadScheduleView.GroupHeaderContentTemplate>

Nothing happen, and the TestCommand is never called in my ViewModel, could you tell me if this is possible, and if yes how to fire this event ? I tried other events than MouseUp and the result is the same.

Thanks for your help,
Doots
