Expression Dark theme throws errors after Telerik UI update

[Patrick]

I am in the process of updating our program from the WPF UI 2013.3 controls to 2015.2. I'm close to completing the changes I need, but I still can't build because I'm getting errors in my ResourceDictionaries:
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
<ResourceDictionary Source="/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>

 All 3 of these (but not the other controls) are throwing the following error when I try to build:

An error occurred while finding the resource dictionary "/Telerik.Windows.Themes.Expression_Dark;component/Themes/Telerik.Windows.Controls.xaml" .CompanySoftwareName\OurFilePath\App.xaml

 

I checked my Expression Dark dll file and noticed that it was referencing the 2013.3.xxx versions of the UI files in question, so I tried copy/pasting the 2015.2.xxx value in those locations, but this wasn't successful.
Is there a new version of this expression dark dll that I need? What am I missing?
I'd be glad to hear any suggestions from other users, or support from Telerik staff directly.

Thank you!

I believe I solved my own problem. I found the 2015 dll for the expression dark theme and dropped it in the assemblies so it used the correct path to the rest of the control xaml files.

It took a LOT of fishing around but it looks like it works.

It broke my Telerik reports, though. :( Still using the 2013 report designer. It's throwing here:

        <tr:ReportViewer
            Name="reportViewerControl"
            ViewMode="PrintPreview" Loaded="reportViewerControl_Loaded">


        </tr:ReportViewer>

 

tr is the following namespace:
xmlns:tr="http://schemas.telerik.com/wpf"

It's throwing a xaml parse exception:
'The invocation of the constructor on type 'Telerik.ReportViewer.Wpf.ReportViewer' that matches the specified binding constraints threw an exception.'

Hello Patrick,

Please review WPF/Silverlight report viewer is blank after upgrading from version prior to Q1 2014 to Q1 2014 or later KB article which elaborates on issues when upgrading Telerik Reporting and/or UI for WPF.

In case the issue persists after troubleshooting it according to the provided KB article, please open a new support ticket for the Telerik Reporting product where you can zip and attach a sample project reproducing the issue.

Thank you.

I've updated to the 2015 Q2 reporting tool, and I'm blocked now due to ReportViewerModel being inaccessible due to being internal:

RadToolBarPanel toolbar = this.reportViewerControl.ChildrenOfType<RadToolBarPanel>().FirstOrDefault();
            var vm = toolbar.DataContext as ReportViewerModel;
            vm.IsExportEnabled = true;

 I tried the solution found at this link:
http://www.telerik.com/forums/sl-reportview---add-buttons-commands

but it didn't make any difference whether I used safe casting or direct casting.

It was working fine with the 2013 telerik reporting tools but does not anymore.

I suppose this thread has meandered a bit, so if there's a better way for us to communicate for support on this issue, please let me know.

Patrick,

As of Telerik Reporting Q3 2014, the WPF ReportViewer's ReportViewerModel is internal (no longer accessible). Instead, you can use the exposed viewer's API.

To continue the communication on the topic, please open a new support ticket in the Telerik Reporting product category.
