Next, we added an event handler to the TreeView control, which enables primitive interaction with the TreeView nodes by the user. We added TreeNode references and children nodes. We used the TreeView control in Windows Forms. Tip: If you double-click on the node "Linux", a MessageBox is shown with that text. This returns a reference to the string that represents the text in the TreeNode. The treeView1_MouseDoubleClick event handler also accesses the Text instance property on the treeView1 control. This returns the selected node if a node is selected.Īnd: After a double-click, a node is selected so this returns a reference to that node in the object model. In the treeView1_MouseDoubleClick method, you can see that the SelectedNode property is accessed on the treeView1 control. TreeNode array = new TreeNode ", node.Text)) Add the third node, and specify these as its children. Create two child nodes and put them in an array. Another node following the first node. TreeNode treeNode = new TreeNode("Windows") Private void Form1_Load(object sender, EventArgs e) Windows Forms program that adds to TreeView: C# In this event handler, we will insert code to build the nodes in the TreeView control. Now, double-click on the Form1 window in the designer so you can create the Form1_Load event. To do this, open the Toolbox panel by clicking on the View and then Toolbox menu item in Visual Studio. First, in this tutorial we add a TreeView control to the Windows Forms Application project. Info: A TreeView control is also available in WPF (Windows Presentation Foundation).Īdd nodes.
