     I downloaded the WPF demo app to get examples on how to create UI items similar to the examples.  I'm finding that I'm always missing references and have to google which reference I need for certain controls.  I also can't find resources, not sure if they are in another library or if they were omitted from the source code.  It's getting frustrating to struggle with every control.

Right now I'm trying to get the RadPieChart to work so I copied in the markup into my page and the RadPieChart wasn't found.  I had to google to find out I was missing a reference to Telerik.Windows.Controls.Chart. 

Now I got that working but noticed I was missing some styles which I found in the Resources.xaml.  When I copy in those styles they have "basedon" set to another style and I don't know if it's missing or if it's a reference.

Any chance these demos could be easier to copy in so I don't have to google everything and figure it out, I don't need anything fancy, I just need it to work so I can start fiddling around with it.

For reference I'm looking at the Layout Control and trying to get a little doughnut pie chart like in the steps per day.

Hello Daniel,

Indeed, extracting a demo from the main solution could be inconvenient. We are considering how ti improve this but at this point I can't point you to an easier approach. However, here are couple of tips that you can keep in mind when extracting a demo.
  • The demo application is using the NoXaml version of the dlls. So, in order to properly run a then reference the NoXaml dlls.

  • The styles targeting Telerik controls in the demos are based on the default style of the corresponding control via the BasedOn attribute. Thus said, the StaticResource keyword used with BasedOn are pointing to styles from the Telerik default style resource dictionaries. When using NoXaml you will need to merge those resources in the application's Resources collection as shown in the Setting a Theme article.

  • The Telerik controls' default styles (when NoXaml dlls are used) are located in the corresponding theme dll. You will need reference it as well. For example Telerik.Windows.Themes.Windows8.dll.

I hope those suggestions help. For your convenience I also attached a runnable version of the Layout Control's First Look example. Note that the example requires NoXaml dlls.

Martin Ivanov

Ok, so I used Nuget to download the Office2013 Theme which I’m using for my app.

I added in all the resource dictionaries mentioned in the article:

 <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/System.Windows.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
                <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>

but it still can’t find the RadChartBaseStyle.  Am I missing a dictionary?  Is it not covered under controls?

Here’s my exception

System.Windows.Markup.XamlParseException
  HResult=0x80131501

Hello Daniel,

The code snippet with the merged resources shown in the Setting a Theme article serves merely as an example that demonstrates how the ResourceDictionary objects should be defined and merged. However, the snippet doesn't contain all required resources. Basically, you will need to merge a ResourceDictionary for each Telerik .dll that contains an UI element. For example, the First Look demo of RadLayoutControl needs the following resources:
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/System.Windows.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.Navigation.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.Chart.xaml"/>
            <ResourceDictionary Source="/Telerik.Windows.Themes.Office2013;component/Themes/Telerik.Windows.Controls.DataVisualization.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

Is this documented anywhere in the WPF Demo?  I'd like to see where to find that for future controls I need.  If it isn't I think it should so you know everything you need to recreate a demo'd control.

I added these resources but I must need to reference another DLL because it's throwing an error now: FileNotFoundException: Could not load file or assembly.  Do I have to install anything else to get this to work?

Hello Daniel,

There is not documentation for the WPF Demo application. To find out what dictionaries you will need to merge you can go to the Getting Started of the control. There find the Assembly Reference section that shows what dlls are required for the control. Also, there is an article listing the dlls needed by every control. After you reference all the required dlls, you can reference also the theme dll, and for each Telerik assemblies merge the corresponding .xaml file. Note that there is a .xaml file in the theme .dll for each Telerik assembly that contains UI. For example:
  • Telerik.Windows.Control.dll ---> Telerik.Windows.Controls.xaml.
  • Telerik.Windows.Control.Navigation.dll ---> Telerik.Windows.Controls.Navigation.xaml.
  • Telerik.Windows.Control.Input.dll ---> Telerik.Windows.Controls.Input.xaml.
  • Telerik.Windows.Control.Chart.dll ---> Telerik.Windows.Controls.Chart.xaml.

About the error, without your project I cannot tell what exactly happens, but my guess is that the theme dll is not reference in the project. The theme dll in this case is Telerik.Windows.Themes.Office2013.dll. You can get it from the "Telerik UI for WPF installation folder/Binaries.NoXaml/" directory.

[quote]To find out what dictionaries you will need to merge you can go to the Getting Started of the control[/quote]

I can't find this in the WPF Demo App, maybe I'm blind.  Right now I click the "EXPLORE ALL CONTROLS" button on the left, then I click LayoutControl under the Layout heading.  Doing this pops up the example of Samantha Johnson Smith with her info and steps per day.  There's a dropdown for more examples, buttons to switch between code and examples and themes on the right.  I don't see a Getting Started button or link anywhere.

 

As for the theme I used the Telerik Nuget repository to install the Office2013 theme.  I checked my references and I have all the DLLs you have listed above and more.  I'll zip up my project and include it.

I can't find this in the WPF Controls Example app, where do I look for this?

I do have the theme installed, I used Nuget and the Telerik Nuget repository to install it.  I double-checked the DLLs you have listed and they are all reference in my app.  I could attach my project, it's just a little big, even zipped up without packages it's coming in at 44 Mb

Hi Daniel,

By Getting Started I meant the Getting Started article of each control you are using. This wasn't clear enough from my side. Please excuse me for this. For example, check the RadChartView's Getting Started for the required chart dlls. Another example, the RadGridView Getting Started article contains the required dlls for the gridview control.

About the project, you cannot attach a .zip in the forums. I could recommend you to open a support ticket from your telerik.coum account and include a runnable project there. Note that the limit there is 20MB, so I would recommend you to isolate your project to contain only Telerik related code.
