How to Get Node Text of treeView on the click event

Question

I want to Get the Text of the node in the treeview. I am using the click() event.. When I am using the AfterSelect() event I can get the node text by e.Node.text . how can I get the text by using Click() event

I don't recommend using the Click event for this. The reason is that there are a lot of different places that the user could click on a TreeView control, and many of them do not correspond to an actual node. The AfterSelect event is a much better choice—it was designed for this usage.

Beyond that, the Click event is rather difficult to use, because it doesn't provide you very much information in the handler method. It doesn't tell you which button was clicked, where the click event occurred, etc. You have to retrieve all of this information manually. It's recommended that you subscribe to either the MouseClick or the MouseDown/MouseUp event instead.

To figure out what the user clicked on, you need to use the TreeView.HitTest method, which returns a TreeViewHitTestInfo object that contains detailed information about the area where the user clicked, or the somewhat simpler TreeView.GetNodeAt method, which will simply return null if no node exists at the location of the click.

Alternatively, to get the currently selected node at any time, you can just query the TreeView.SelectedNode property. If no node is selected, this will also return null.

It would be better to use treeView1_AfterSelect() event because that gives the correct selected node text. The treeView1_Click() event will show the oldest selected not, not the immediate selected one.

You can achieve the selected node text on Click event

 private void treeView1_Click(object sender, EventArgs e)
 {
    MessageBox.Show(treeView1.SelectedNode.Text);
 }

Remember, the difference between Click() and AfterSelect() event is their eventargs

treeView1_Click(object sender, EventArgs e)
treeView1_AfterSelect(object sender, TreeViewEventArgs e)

EDIT: Try out this on Click() event, I am sure this will help you.

 private void treeView1_Click(object sender, EventArgs e)
 {
   TreeViewHitTestInfo info = treeView1.HitTest(treeView1.PointToClient(Cursor.Position));
   if (info != null)
     MessageBox.Show(info.Node.Text);
 }
