When you run the demo application and expand the root nodes, the TreeView looks like this:Ĭlick here to download the demo project. If you had, say, three related tables (Master –> Detail –> DetailInfo) then you could have the ‘DetailTemplate’ be a HierarchicalDataTemplate whose ItemsSource was bound to the DataRelation between ‘Detail’ and ‘DetailInfo,’ and the ItemTemplate a DataTemplate which displays the pertinent information in that table. Here is the XAML for a Window which contains a TreeView configured to load and display that data:

We want a TreeView to display the Master rows as top-level nodes and the Detail rows as children of their respective parent node. The resultant DataSet has two DataTables (‘Master’ and ‘Detail’) and one DataRelation (‘Master2Detail’). Here is a method in a class called DataSetCreator which creates a DataSet with two related DataTables: You need to use a HierarchicalDataTemplate for every non-leaf level of nodes, in other words, only the very lowest DataTable in the hierarchy is displayed with a non-hierarchical DataTemplate. The basic gist of the solution is to bind the top level of TreeViewItems against the master DataTable, and then bind against DataRelations for any descendants of the root nodes. If you are currently in that situation, rest assured that it is actually fairly trivial to do this in WPF. In many situations the developer just needs to bind the TreeView directly to the DataSet which was populated with database data creating custom domain objects and collections of those objects can be overkill sometimes. Many applications need to display hierarchical data in a TreeView, and often that data is retrieved from a database. The technique presented herein could easily be extended to fit more sophisticated requirements, such as binding to more than two tables. Selects all the title elements of the book elements of the bookstore element that have a price element with a value greater than 35.This blog entry demonstrates the fundamentals of binding a WPF TreeView to a DataSet with two related DataTables. Selects all the book elements of the bookstore element that have a price element with a value greater than 35.00 Selects the last but one book element that is the child of the bookstore element Selects the last book element that is the child of the bookstore element Selects the first book element that is the child of the bookstore element In the table below we have listed some XPath expressions and the result of the expressions: XPath Expression References DOM Node Types DOM Node DOM NodeList DOM NamedNodeMap DOM Document DOM Element DOM Attribute DOM Text DOM CDATA DOM Comment DOM XMLHttpRequest DOM Parser XSLT Elements XSLT/XPath Functions Web Services XML Services XML WSDL XML SOAP XML RDF XML RSS XSD Data Types XSD String XSD Date/Time XSD Numeric XSD Misc XSD Reference
