Hi Mukesh,

By Values of Nodes i suppose you are refering to the Tag property. So as Sanjay told in the NodeMouseClick event we can get the Node clicked by this statement
TreeNode tn = e.Node;

Now to get all the child nodes and there respective value(Tag). We can loop through the nodes and get there respective values.
Here's the sample code

C#

TreeNode tn = e.Node;
           string st = null;

           foreach (TreeNode t1 in tn.Nodes)
           {
               st += "Node Name:" + t1.Text + " Node Data: " + t1.Tag.ToString()+ "\n";


           }
           MessageBox.Show(st);

Hope this helps you. Incase of any confusion do let me know.

I have used TreeView Control in my Project like

+ Jwellerry=J <-value
+ Gold=G
+ Ring=R
+ Silver=S
+ Electronics=E
+ Computer=C
+ Desktop=D
+ Laptop=L

As per Above example.....
Category = Jwellery,Electronics
SubCategory = Gold,Silver,Computer
Division = Ring,Desktop,Laptop

And all Category,Subcategory and division have values like J,G,R,S,E etc....
And now I want all values OnSelectedNodeChange but I got only Category and SubCategory Values but didn't get Division value.....

So please help me out......

On "NodeMouseClick" event there is a TreeNodeMouseClickEventArgs object e.

for getting the Node object on which the event has fired use
"e.Node"
