Collapsed RangeBarSeries throw exception when selection behavior is present

[LOUGE]

Executing this code throw an exeption :

<telerik:RadCartesianChart >

    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:CategoricalAxis GapLength="0" />
    </telerik:RadCartesianChart.HorizontalAxis>

    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis />
    </telerik:RadCartesianChart.VerticalAxis>

    <telerik:RadCartesianChart.Grid>
        <telerik:CartesianChartGrid MajorLinesVisibility="Y" />
    </telerik:RadCartesianChart.Grid>

    <telerik:RadCartesianChart.SelectionPalette>
        <telerik:ChartPalette>
            <telerik:ChartPalette.GlobalEntries>
                <telerik:PaletteEntry Fill="Orange" />
            </telerik:ChartPalette.GlobalEntries>
        </telerik:ChartPalette>
    </telerik:RadCartesianChart.SelectionPalette>

    <telerik:RadCartesianChart.Behaviors>
        <telerik:ChartSelectionBehavior />
    </telerik:RadCartesianChart.Behaviors>

    <telerik:RangeBarSeries  ItemsSource="{Binding Items}"
                             LowBinding="Min"
                             HighBinding="Max"
                             CategoryBinding="X"
                             CombineMode="Cluster" />


    <telerik:RangeBarSeries ItemsSource="{Binding Items2}"
                            LowBinding="Min"
                            HighBinding="Max"
                            CategoryBinding="X"
                            CombineMode="Cluster"
                            Visibility="Collapsed" />

</telerik:RadCartesianChart>

If Visibility is sets to Hidden everithing works as expected.
Setting Opacity to 0 doesn't work (the bar is visible), it's normal or not ?

Hi,

Thank you for the provided code, we can confirm that this is indeed an issue in the chart, that has been logged for our developers to debug and provide a fix for one of the future versions of the control. We have updated your Telerik points for the feedback.

Greetings,
Nikolay

I have confirmed that this is still a bug in 2014.1.331.40

Hi Leland,

I have just tested this and I ca assure you that the bug was fixed a long time ago. There is no exception with the latest internal assemblies we have and assemblies from 2014.1.331.

I have attached the project I tested with for a reference, so that you can test. I used exactly 2014.1.331.40 dlls and everything works correctly on my machine. Do run it and see how it goes.

Perhaps you are dealing with another bug. You can see what are the differences between the project and your actual application and try to look for where the issue might be hiding. If you need further assistance, I will ask that you send to us a small project that demonstrates the issue at hand so that we can look into it.

Well, my experience is different. I was ready to give up on the functionality of selecting a rangebarseries, until I stumbled upon this post. I changed my visibility converter from a Collapsed to a Hidden and all miraculously works as expected. 

Here is my xaml if you are interested.

<telerik1:RadCartesianChart x:Name="RadCartesianChart" ClipToBounds="False" Margin="0,40,0,0" Visibility="{Binding ElementName=paredoOn, Path=IsChecked, Converter={conv:BoolToOppositeVisibilityHiddenConverter}}">

Leland,

First I would like to know if you tested the project I sent in my previous post. Do you get an exception when you run it?

I have now attached a second project. In it I have used the xaml you sent. Well, since you sent your xaml only, many things were missing and I had to delete some code in order to get it to work. Finally, I got it working and selection is done, no exception is thrown and a command is invoked when selection changes. Do test this and let us know how it goes.

The original issue in this thread was that if there was a present Collapsed series, the selection behavior threw an exception upon mouse click. If you get a different error, please open a new thread so that issues are isolated, this will make communication easier.

If you still experience issues with this, I will ask that you modify the project I attached, and send it back to us for investigation. Thank you for understanding.

Petar Marchev
