Selecting Nodes

Selecting a Single Node

To select a node use the Selected property of RadTreeNode. The following example demonstrates how to do it.

radTreeView1.SelectedNode = radTreeView1.Nodes[0];

RadTreeView1.SelectedNode = RadTreeView1.Nodes(0)

Selecting Multiple Nodes

To enable the multiple selection the MultiSelect property must be set to true. The default value is false.

Selection Example Description
Single Selection The user can select a single node by clicking the node.
Multiple Selection using the Shift key To select a continuous series of multiple nodes at one time hold Shift and click on a node using the mouse. That will select all nodes between the first selected node and the node that was just clicked. The screenshot shows nodes selected between "Deleted Items" and "Large Mail".
Multiple Selection using the Ctrl key treeview-working-with-nodes-selecting-nodes 003 To select multiple nodes in distributed throughout, hold Ctrl and click on each node using the mouse. That will select the clicked node or unselect the previously selected nodes. The screenshot shows the "Deleted Items" and "Send Items" nodes selected.

Selecting Multiple Nodes Programmatically

To select multiple nodes through the API, just set the Selected property of the desired nodes to true. The example below adds four nodes, then selects the last two nodes.

radTreeView1.MultiSelect = true;
RadTreeNode Node1 = new RadTreeNode("Inbox");
RadTreeNode Node2 = new RadTreeNode("Deleted Items");
RadTreeNode Node3 = new RadTreeNode("Outbox");
RadTreeNode Node4 = new RadTreeNode("Sent");
radTreeView1.Nodes.Add(Node1);
radTreeView1.Nodes.Add(Node2);
radTreeView1.Nodes.Add(Node3);
radTreeView1.Nodes.Add(Node4);
Node3.Selected = true;
Node4.Selected = true;

RadTreeView1.MultiSelect = True
Dim Node1 As New RadTreeNode("Inbox")
Dim Node2 As New RadTreeNode("Deleted Items")
Dim Node3 As New RadTreeNode("Outbox")
Dim Node4 As New RadTreeNode("Sent")
RadTreeView1.Nodes.Add(Node1)
RadTreeView1.Nodes.Add(Node2)
RadTreeView1.Nodes.Add(Node3)
RadTreeView1.Nodes.Add(Node4)
Node3.Selected = True
Node4.Selected = True
