How to Get Node Value and Set Selected by Node Value in Treeview

[Brijendra Kumar]

Hi All,

I have a treeview control in my page.
This is like as follows:

    Value is in []

    AAAA [1]
        aaa [1]
              BBB [1]
              BBB [2]
              BBB [3]
        aaa [2]
        aaa [3]
        aaa [4]


I have to find node "BBB" whose value is "3". Does anybody know then plz tell me how to get and set selected using Javascript.

Thanks in advance....

Hello Brijendra Kumar,

You can use a helper JavaScript routine:

function FindNodeByTextAndValue(treeView, text, value)
{
 
 var allNodes = treeView.get_allNodes();
 for (var i = 0; i < allNodes.length;i++)
 {
    var node = allNodes[i];
    if (node.get_text() == text && node.get_value() == value)
      return node;
 }
 
 return null;
}

And here is how to use it:

var treeView = $find("<%= RadTreeView1.ClientID %>");
var myNode = FindNodeByTextAndValue(treeView, "BBB", "3");
if (myNode)
  myNode.select();
