[Xavier]

Hi,

Telerik in webpage is loading very slowly when i am drilling down further on the final node.Can i able to limit that ?
I have tree like below.

Root Node:
    Node 1
    Node 2
    Node 3
        Node 3.1
        Node 3.2
            Node 3.2.1

For example In the node 3.2.1,its having 30 items ,if the item count is > 20 , i need to create a new node called "showallitems" and display all the 20 items under "showallitems".
        
Please help me.

Hi Xavier,

Please take a look at the RadTreeNodeCollection and use the insertNode and deleteNode methods in onClientNodeExpanding client-side event.

Thanks i have added the node with the program flow as a new node with the text "ShowAllItems". and i am also added the items except it under node 2.1 in below show all items.

Now my Tree is like this,

Node 1
Node 2
Node 2.1
Item 1
Item 2
ShowAllItems
Item 3
Item 4

when i am expanding the showAllItems node, i want to move the item 3 and 4 under the node 2.1 next to item 2 and to remove showAllItems after that.

Is it possible, coz i am loading the items 3 & 4 onexpand_event of showAllItems. All Above things i am doing on server side.

Please help me.

Regards,
Xavier

Hello Xavier,

You can try this code where "RadTreeView1" is the ID of the RadTreeView:

protected void RadTreeView1_NodeExpand(object sender, RadTreeNodeEventArgs e)
   {
      RadTreeNode node1 = e.Node;
      RadTreeView1.Nodes.Add(node1);
   }

Hope this will be helpful.
