Unhandled System.InvalidOperationException in TimeBar

[Grant]

Hi,
I'm received a unhandled exception crash report from a application I have deployed in the field. I'm not able to reproduce this when debugging or running on a local instance. I don't see any of my code in the call stack so I'm wondering if you have seen this issue before or have any idea how I might try and reproduce it or work around it?

Here is the XAML:

<telerik:RadTimeBar x:Name="RadTimeBar" IsSnapToIntervalEnabled="False" Margin="1" Height="75" SelectionTitleFormatString="{}{0:HH':'mm}"
                    PeriodStart="{Binding StartDate, Mode=TwoWay}" PeriodEnd="{Binding EndDate, Mode=TwoWay}"
                    SelectionStart="{Binding SelectionStart, Mode=TwoWay}" SelectionEnd="{Binding SelectionEnd, Mode=TwoWay}"
                    MinSelectionRange="{Binding MinSelectionRange, Mode=TwoWay}" MaxSelectionRange="{Binding MaxSelectionRange, Mode=TwoWay}"
                    VisiblePeriodStart="{Binding VisiblePeriodStart, Mode=TwoWay}" VisiblePeriodEnd="{Binding VisiblePeriodEnd, Mode=TwoWay}"
                    SelectionChanged="RadTimeBar_SelectionChanged">

    <telerik:RadTimeBar.Intervals>
        <telerik:HourInterval IntervalSpans="1,2,6"/>
    </telerik:RadTimeBar.Intervals>
</telerik:RadTimeBar>

Here is the unhandled exception information:

Hi Grant,

One other client has reported the same problem. However, he was not able to send me a project, demonstrating this problem. I did my best to try to reproduce the problem locally, but to no avail. As we would rather not fix problems that we cannot reproduce and debug, it would be great if you could open a new support ticket and send me a running test project, demonstrating the exception, together with a video, showing the steps that lead to it.

Hi Tsvetie, As I said I am unable to reproduce this issue as well so I cannot submit a sample project.

I believe it may repro only in OOB mode when running on XP but still have not been able to reproduce it.

Is there any advice on how to work around this issue (I've noticed this control is very particular in binding ordering) as this is causing a crash in my application and is clearly in Telerik code.

Thanks,
Grant

Hi Grant,

As Tsvetie said, it is hard to fix something that cannot be reproduced as it might lead to other unwanted behaviors what we do not want, thus we cannot do much in this case unless there is a sample we could work on.
