Telerik Reporting and Docking

[Mark]

I am not sure if this is reporting issue or docking issue. (I did not see a forum for WPF Reporting)

I have an issue using the Telerik reporting Q3 2012 (SP1) Specifically the Telerik.ReportViewer.Wpf.dll (version 6.2.13.123)

I create a WPF application
On the MainWindow.xaml, I add RadDocking as follows:
 <Grid>
   <telerik:RadDocking>  
     <telerik:RadSplitContaier> 
       <telerik:RadPaneGroup>
        <telerik:RadPane>
           <tr:ReportViewer />
        </telerik:RadPane>
       </telerik:RadPaneGroup>
     </telerik:RadSplitContaier> 
   </telerik:RadDocking>   
 </Grid>

When I run this, the main window opens fine. Now drag the window and dock it somewhere in the main window.
The result is an exception (NullReferenceException) the stack trace mentions the ReportViewerModel.SetReportSourceEffective (ReportViewerModel.cs line 983) 

Note: This seems to be an issue with the SP 1 dll because this example code runs fine when using the Telerik reporting Q3 2012 dlls (i.e Telerik.ReportViewer.Wpf.dll  version 6.2.12.1017)

Help?

Hi Mark,

We will need additional details or better yet a runnable sample that exhibits the issue so that we are able to reproduce it at our end - this will help us identify the problem faster and advise you accordingly. Additionally, please post the full stack trace, so we can get better idea where the problem occurs.

All the best,
Steve

I tried to upload a sample solution that reproduces the problem, but I am only allowed to upload images. Hmmmmmm....

It is easy to reproduce, please to the following experiment. Simply create a WPF solution with the following as the MainWindow.xaml
<Window x:Class="ReportingAndDocking.MainWindow"
        xmlns:tr="http://schemas.telerik.com/wpf" 
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <telerik:RadDocking>
            <telerik:RadSplitContainer>
                <telerik:RadPaneGroup >
                    <telerik:RadPane Header="Dock Me">
                        <tr:ReportViewer Name="reportViewer" />
                    </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
        </telerik:RadDocking>
    </Grid>
</Window>

Then run the program and dock the RadPane "Dock Me" anywhere in the app window.

Telerik.ReportViewer.Wpf 6.2.12.1017 has no problem

but

Telerik.ReportViewer.Wpf 6.2.13.123 gives the following error:

{"Object reference not set to an instance of an object."}

Hi Mark,

Thank you for the provided input. We were able to reproduce the issue locally and it is now logged into our systems. We will do our best to fix it as soon as possible. For the time being there is no available workaround, but if we find something we will get back to you.

 We apologize for the temporary inconvenience. Your Telerik points have been updated.

Greetings,
IvanY

For a work around we use set ReportSource to an empty report just after InitializeComponent (of the view that contains the ReportViewer)

Thank you for your efforts on this issue.
