Introduction
This article will help to modify the text of the selected node of ASP.NET Tree View. I hope I can explain this in a simple manner so that people can easy to understand and implement it. I did this for my application and I could avoid the page post back.
Using the code
I have bound the Tree View like below:
TreeNode root = new TreeNode("School");
TreeNode teach = new TreeNode("Teachers");
TreeNode stud = new TreeNode("Students");
TreeNode teach1 = new TreeNode("Teacher1");
TreeNode teach2 = new TreeNode("Teacher2");
TreeNode teach3 = new TreeNode("Teacher3");
TreeNode stud1 = new TreeNode("Student1");
TreeNode stud2 = new TreeNode("Student2");
TreeNode stud3 = new TreeNode("Student3");
TreeNode stud4 = new TreeNode("Student4");
teach.ChildNodes.Add(teach1); teach.ChildNodes.Add(teach2);
teach.ChildNodes.Add(teach3);
stud.ChildNodes.Add(stud1); stud.ChildNodes.Add(stud2);
stud.ChildNodes.Add(stud3); stud.ChildNodes.Add(stud4);
root.ChildNodes.Add(teach); root.ChildNodes.Add(stud);
TreeView1.Nodes.Add(root);
And attach this java script event to the Treeview
this.TreeView1.Attributes.Add("oncontextmenu", "RightClick(event);");
Java script code:
function RightClick(event)
{
var obj = event.srcElement || event.target ;
var seltreeNode = obj;
alert(seltreeNode.innerHTML);
seltreeNode.innerHTML = "Rajesh Babu";
}
Happy Coding!
