Then used as the items source for the TreeView. ![]() ![]() In the code-behind, we simply create two Family instances, fill each of them with a set of members, and then add each of the families to a list, which is The dynamic TreeView will be created using the jQuery jsTree plugin and the data for the TreeView will be fetched from database using Entity Framework in ASP.Net MVC Razor. Select MVC project template from the ASP.NET Template Wizard to create MVC app. Figure 2 Creating Web Application in VS 2017. Select 'Web' tab from the left panel and select the ASP.NET Web Application. In both templates, we use an image representing either a family or a family member, and then we show some interesting data about it as well, like theĪmount of family members or the person's age. MVC Here Mudassar Khan has explained with an example, how to create dynamic TreeView from database in ASP.Net MVC Razor. Open Visual Studio 2017 and click on New Project. Had wanted each FamilyMember to keep a collection of their children and perhaps their children's children, then we would have used a hierarchical template First one you call this method from your action in MVC or other part of your application call like that Treeview (0,0,0). The template defined for the FamilyMember type is a regular DataTemplate, since this type doesn't have any child members. The template defined for the Family type is a hierarchical template, using the Members MenuItem root = new MenuItem() Īs mentioned, the two templates are declared as a part of the TreeView resources, allowing the TreeView to select the appropriate template based on theĭata type that it's about to show. Public partial class TreeViewDataBindingSample : Window Namespace WpfTutorialSamples.TreeView_control In the following example, I'll show you just how easy it is to get started with the HierarchicalDataTemplate: Which property to use as a source for child items of the node. Instead, we use the HierarchicalDataTemplate, which allows us to template both the tree node itself, while controlling The WPF TreeView supports data binding, like pretty much all other WPF controls does, but because the TreeView is hierarchical in nature, a normalĭataTemplate often won't suffice. This demo uses an if-else statement to add a Delete icon link to the child items.The TreeView control: TreeView, data binding and multiple templates This can be done using the dataSource property that is a member of the fields. In the template, you can access the Model properties to which the node is bound and render the desired content. TreeView can load data either from local data sources or remote data services. The TemplateId option in the TreeView configuration defines the name of an external Kendo UI template. The current demo shows the TreeView template using remote data binding. ![]() Another benefit is the possibility to add DOM event handlers, such as click, hover and more, if you need to respond to them. You can navigate through the nodes and their children, and you have a full control over the rendering of custom content in nodes with the help of the TreeView templates.ĭefining a template allows you to render arbitrary content according to the specific data and logic. The Telerik UI for ASP.NET MVC TreeView component represents the data as a tree-like structure. Focus on providing essential templating features for common user-interface (UI) rendering scenarios with a heavy emphasis on performance over feature glut by trading convenient syntax sugar for improved performance.Represent a substitute for traditional HTML string-building in JavaScript and help you create HTML chunks that can be automatically merged with JavaScript data.Telerik UI for ASP.NET MVC provides a user-friendly and a high-performing JavaScript templating engine based on the Kendo UI Templates, and also:
