Visual Studio Design time error rendering the control - Object reference not set to an instance of an object

When attempting to view the page in design view, here's what it looks like:

 

Here is the markup:

    <telerik:RadPanelBar ID="RadPanelBar1" runat="server">
        <Items>
            <telerik:RadPanelItem runat="server" Expanded="True" PreventCollapse="true">
                <HeaderTemplate>
                    <div ID="content-header">
                        Auditing Report | GPO Changes For User
                    </div>
                </HeaderTemplate>
                <ContentTemplate>
                    <div ID="content-body">
                        <telerik:ReportViewer ID="ReportViewer1" runat="server" ReportBookID="" Width="100%" Height="12in">
                        </telerik:ReportViewer>
                    </div>
                </ContentTemplate>
            </telerik:RadPanelItem>
        </Items>
    </telerik:RadPanelBar>

Hi Cameron,

Thank you for reporting this problem!

It was verified and confirmed as an issue.

The workaround that you can use until the problem gets fixed is move the Report Viewer outside of the PanelBar which will render both components correctly and allow you to configure their properties. Once you are ready move back the ReportViewer tag into the <ContentTemplate> of the <telerik:RadPanelItem>.

As a small note of gratitude for your bug report, I updated your Telerik points.

Best regards,
Rumen
