[c#] How to select a node of treeview programmatically in c#?

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"); 
}

yourNode.Toggle(); //use that function on your node, it toggles it

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.

TreeViewItem tempItem = new TreeViewItem();
TreeViewItem tempItem1 = new TreeViewItem(); 
tempItem =  (TreeViewItem) treeView1.Items.GetItemAt(0);    // Selecting the first of the top level nodes
tempItem1 = (TreeViewItem)tempItem.Items.GetItemAt(0);      // Selecting the first child of the first first level node
SelectedCategoryHeaderString = tempItem.Header.ToString();  // gets the header for the first top level node
SelectedCategoryHeaderString = tempItem1.Header.ToString(); // gets the header for the first child node of the first top level node
tempItem.IsExpanded = true;         //  will expand the first node

private void btn_CollapseAllAndExpandFirstLevelUnderRoot(object sender, EventArgs e)

{
    //this example collapses everything, then expands the first level under the root node.

    tv_myTreeView.CollapseAll();
    TreeNode tn =  tv_myTreeView.Nodes[0];
    tn.Expand();
}

Call the TreeView.OnAfterSelect() protected method after you programatically select the node.
