How to display a particular node

[Bernard]

Hello,
I populate aRadreeview on the server with lot of nodes.
I would like to display the first checked node.
Is there any way to do that ?

Hi Bernard,


I am not quite sure about the requirement. If you want to access the first cehcked node in the treeview, then the following code will help you.

Client code:

function getChedcked() {
    var treeView = $find("<%=RadTreeView1.ClientID%>");
    var c = treeView.get_checkedNodes();
    alert(c[0].get_text());
}

Hi Shinu,
Many thanks for your answer, but It's not what I am loooking for.
It's my fault because my english is limited !
I try again:
For example, I have 400 nodes to display in a Treeview.
The user can only see a few of them, and he has to scroll to see the others...
I would like to "position" the scroll (on server) so the 350th node (for example) is showned.

I hope you'll anderstand me.

Hello Bernard,

Well you can find the first node using Shinu's approach, and then, you can call it's scrollIntoView method.

Hope this is helpful for you!

Hi Nikolay, Hello Shinu,

It's works. I didn't see this client method. I was looking to a (method or a proprety) on server. 

function

 

pageLoad()

 

{

 

    var tree= $find("<%= leftTV.ClientID %>");

 

 

    var c = tree.get_checkedNodes();

 

 

    if (c != null)

 

    {

        checkedNode = c[0];

 

        if (checkedNode != null)

 

        {

            var nodeElement = checkedNode.get_element();

 

            nodeElement.scrollIntoView();

        }

    }

}

Thank you both of you ! a evry helpful team !!
Bye
