--- title: Getting Started page_title: Getting Started description: Check our "Getting Started" documentation article for the RadTimeline {{ site.framework_name }} control. slug: radtimeline-getting-started tags: getting,started published: True position: 1 --- # Getting Started with {{ site.framework_name }} Timeline This topic will walk you through the creating of __RadTimeline__. ## Assembly References In order to use __RadTimeline__ control in your project you have to add references to the following assemblies: * __Telerik.Licensing.Runtime__ * __Telerik.Windows.Controls.dll__ * __Telerik.Windows.Controls.DataVisualization.dll__ * __Telerik.Windows.Data.dll__ >tip With the 2025 Q1 release, the Telerik UI for WPF has a new licensing mechanism. You can learn more about it [here]({%slug installing-license-key%}). ### Adding Telerik Assemblies Using NuGet To use __RadTimeline__ when working with NuGet packages, install the `Telerik.Windows.Controls.DataVisualization.for.Wpf.Xaml` package. The [package name may vary]({%slug nuget-available-packages%}) slightly based on the Telerik dlls set - [Xaml or NoXaml]({%slug xaml-vs-noxaml%}) Read more about NuGet installation in the [Installing UI for WPF from NuGet Package]({%slug nuget-installation%}) article. ## Adding RadTimeline to the Project You can include the control in your page by either dragging it from the toolbox in Visual Studio or manually creating the control. __Example 1__ demonstrate how to create __RadTimeline__ in XAML. #### __[XAML] Example 1: Creating RadTimeline control__ {{region xaml-radtimeline-getting-started_0}} {{endregion}} #### __Figure 1: RadTimeline visualization__ ![{{ site.framework_name }} RadTimeline RadTimeline visualization](images/RadTimeline_Getting_Started_0.png) ## RadTimeline items The RadTimeline control presents its data in two types of occurrences(events). The first one is a one-time occurrence which happens once in a time. The second type represents periodical occurrence. It requires a strict __Start__ and __End__ time to be presented. #### __Figure 2: RadTimeline items visualization__ ![{{ site.framework_name }} RadTimeline RadTimeline items visualization](images/RadTimeline_Getting_Started_1.PNG) >tip More information about how to populate the control with __TimelineItems__ and __TimelineInstantItems__ can be found in the [DataBinding help article]({%slug radtimeline-databinding%}) in our documentation. ## Setting a Theme The controls from our suite support different themes. You can see how to apply a theme different than the default one in the [Setting a Theme]({%slug styling-apperance-implicit-styles-overview%}) help article. >important Changing the theme using implicit styles will affect all controls that have styles defined in the merged resource dictionaries. This is applicable only for the controls in the scope in which the resources are merged. To change the theme, you can follow the steps below: * Choose between the themes and add reference to the corresponding theme assembly (ex: **Telerik.Windows.Themes.Windows8.dll**). You can see the different themes applied in the **Theming** examples from our {% if site.site_name == 'WPF' %}[WPF Controls Examples](https://demos.telerik.com/wpf/){% else %}[Silverlight Controls Examples](https://demos.telerik.com/silverlight/#Timeline/Theming){% endif %} application. * Merge the ResourceDictionaries with the namespace required for the controls that you are using from the theme assembly. For the RadTimeline, you will need to merge the following resources: * __Telerik.Windows.Controls__ * __Telerik.Windows.Controls.DataVisualization__ __Example 2__ demonstrates how to merge the ResourceDictionaries so that they are applied globally for the entire application. #### __[XAML] Example 2: Merge the ResourceDictionaries__ {{region radtimeline-getting-started_7}} {{endregion}} >Alternatively, you can use the theme of the control via the {% if site.site_name == 'WPF' %}[StyleManager](https://docs.telerik.com/devtools/wpf/styling-and-appearance/stylemanager/common-styling-apperance-setting-theme-wpf){% else %}[StyleManager](https://docs.telerik.com/devtools/silverlight/styling-and-appearance/stylemanager/common-styling-apperance-setting-theme){% endif %}. __Figure 2__ shows a RadTimeline with the **Windows8** theme applied. #### __Figure 2: RadTimeline with the Windows8 theme__ ![RadTimeline with Windows8 theme](images/RadTimeline-setting-theme.png) {% if site.site_name == 'WPF' %} ## Telerik UI for WPF Learning Resources * [Telerik UI for WPF Timeline Component](https://www.telerik.com/products/wpf/timeline.aspx) * [Getting Started with Telerik UI for WPF Components]({%slug getting-started-first-steps%}) * [Telerik UI for WPF Installation]({%slug installation-installing-which-file-do-i-need%}) * [Telerik UI for WPF and WinForms Integration]({%slug winforms-integration%}) * [Telerik UI for WPF Visual Studio Templates]({%slug visual-studio-templates%}) * [Setting a Theme with Telerik UI for WPF]({%slug styling-apperance-implicit-styles-overview%}) * [Telerik UI for WPF Virtual Classroom (Training Courses for Registered Users)](https://learn.telerik.com/learn/course/external/view/elearning/16/telerik-ui-for-wpf) * [Telerik UI for WPF License Agreement](https://www.telerik.com/purchase/license-agreement/wpf-dlw-s) {% endif %} ## See Also * [Overview]({%slug radtimeline-overview%}) * [MVVM Support]({%slug radtimeline-mvvm-support%})
