Used treeview.SelectedNode
to select a child node. How to invoke treeview.AfterSelect
event when a node is selected programmatically?
this.treeView1.SelectedNode = this.treeView1.Nodes[0].Nodes[0].Nodes[0].Nodes[0];
if (this.treeView1.Nodes[0].Nodes[0].Nodes[0].Nodes[0].IsSelected)
{
MessageBox.Show("Node is selected");
}
Use the FindNode method to get a node from the TreeView control at the specified value path. The value path contains a delimiter-separated list of node values that form a path from the root node to the current node. Each node stores its value path in the ValuePath property.
Solution 1Use TreeView. SelectedNode[^] property, which get or set selected node for currently selected Treeview. If no TreeNode is currently selected, the SelectedNode property is a null reference (Nothing in Visual Basic).
The Nodes property holds a collection of TreeNode objects, each of which has a Nodes property that can contain its own TreeNodeCollection. This nesting of tree nodes can make it difficult to navigate a tree structure, but the FullPath property makes it easier to determine your location within the tree structure.
Apologies for my previously mixed up answer.
Here is how to do:
myTreeView.SelectedNode = myTreeNode;
I have tested the code below and it works:
public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { treeView1.Nodes.Add("1", "1"); treeView1.Nodes.Add("2", "2"); treeView1.Nodes[0].Nodes.Add("1-1", "1-1"); TreeNode treeNode = treeView1.Nodes[0].Nodes.Add("1-2", "1-3"); treeView1.SelectedNode = treeNode; MessageBox.Show(treeNode.IsSelected.ToString()); } }
treeViewMain.SelectedNode = treeViewMain.Nodes.Find(searchNode, true)[0];
where searchNode is the name of the node. I'm personally using a combo "Node + Panel" where Node name is Node + and the same tag is also set on panel of choice. With this command + scan of panels by tag i'm usually able to work a treeview+panel full menu set.
