Setting a Theme

The purpose of this article is to show you how to set a built-in theme to RadGanttView for WPF.

Detailed information about the use of implicit styles can be found here.

So, in order to set a theme to the GanttView, you should merge the following xaml files in App.xaml file:

• System.Windows.xaml

• Telerik.Windows.Controls.xaml

• Telerik.Windows.Controls.GanttView.xaml

There are two ways to reference the needed xaml files:

• Directly from the theme assembly:

  Let's, for example, apply Windows8 theme to the control. This means that we should add a reference to Telerik.Windows.Themes.Windows8.dll as well:

  

  Then merge the xaml files in the App.xaml like this:

      <Application.Resources> 
          <ResourceDictionary> 
              <ResourceDictionary.MergedDictionaries> 
                  <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/System.Windows.xaml"/> 
                  <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.xaml"/> 
                  <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8;component/Themes/Telerik.Windows.Controls.GanttView.xaml"/> 
              </ResourceDictionary.MergedDictionaries> 
          </ResourceDictionary> 
      </Application.Resources> 
  

• Copy the xaml files to a folder in the project:

  Create a Theme folder and copy the required files from Themes.Implicit/../Windows8/../Themes/ folder located in the installation folder of UI for WPF:

  

  Then merge the xaml files in the App.xaml like this:

      <Application.Resources> 
          <ResourceDictionary> 
              <ResourceDictionary.MergedDictionaries> 
                  <ResourceDictionary Source="Themes/System.Windows.xaml" /> 
                  <ResourceDictionary Source="Themes/Telerik.Windows.Controls.xaml" /> 
                  <ResourceDictionary Source="Themes/Telerik.Windows.Controls.GanttView.xaml" /> 
              </ResourceDictionary.MergedDictionaries> 
          </ResourceDictionary> 
      </Application.Resources> 
  

Either way you choose, the end result will be the following:
