How to get list of all parent node values

[Manoj]

Hi Team,
    How can we get the list of parent node value at a perticular level .?
My requirment is I have to pass the list of parent node value as a string ( each node will separated with a comma ) at a perticular level . If I am expanding the level 4 then , I need parentnodevalue(0),parentnodevalue(1),parentnodevalue(2),parentnodevalue(3),currentnodevalue(4) . can you suggest me

Regards

Hi Manoj,

I have used the following code to get the parent of a selected node.

<radT:RadTreeView ID="RadTreeView1" runat="server" OnNodeClick="RadTreeView1_NodeClick" AutoPostBack=true>

</radT:RadTreeView>

protected void RadTreeView1_NodeClick(object o, RadTreeNodeEventArgs e)

{

SelectParents(e.NodeClicked);

}

protected void SelectParents( RadTreeNode node)

{

if (node.Parent != null)

{

node.Parent.Selected = true;

}

}

You can loop through the node collection and get the parent nodes 

foreach (RadTreeNode node in nodeCollection)
            {
//Write the logic to find the parent up to the selected node.               
            }

Hi Shinu,
    Thanks for your reply . But I getting compile time error when trying to check your suggested code . Can you look into it .
When I am expanding any perticular node , I need all the parent node values .

Hi  Manoj,

Give a try with the following client side code and see whether it helps.

ASPX:

<telerik:RadTreeView ID="RadTreeView1"   runat="server" OnClientNodeExpanding="ClientNodeExpanding" >

<Nodes>

......

JS:

<script type="text/javascript" >
 function ClientNodeExpanding(sender, eventArgs)
 {
   var Tree=sender;
   var nodes=Tree.get_nodes();

   var currentNode = eventArgs.get_node();
   if(currentNode!=null)
   {
     for(i=0;i<=nodes.get_count();i++)
      {

        var nodeText=nodes.getNode(i).get_text();
         alert(nodeText)
        if(nodeText==currentNode.get_text())
        {
          break;
        }
       }
   }
 }
</script>

Thanks

Hi Shinu,

             Thanks for you reply . I tried in a different manner . Here I have attached the code .

 

RadTreeNode

curNode;

 

 

String strNodeCollection = "";

 

 

String strNodeColl = "";

 

curNode = e.Node;

 

Int32 intSelectedNodeLevel;

 

intSelectedNodeLevel = e.Node.Level;

 

if (intSelectedNodeLevel >= 0)

 

{
    

for (int i = intSelectedNodeLevel; i >= 0; i--)

 

    {

 

        if (strNodeCollection == "")

 

        {

            strNodeColl = curNode.Value;

            strNodeCollection = strNodeColl;

        }

 

        else 

 

        {

 

            RadTreeNode tnode = curNode.ParentNode;

 

            strNodeCollection = tnode.Value +

"," + strNodeCollection ;

 

            curNode = tnode;

        }

    }

}

With Regards
Manoj
