Can you please give me some reply

Hi,
I suppose you need to copy the selected nodes to 'rlbDealers' listbox and also need to select the child nodes of selected parent node. So please try the following code snippet to achieve the scenario.
C#:

/*to transfer the selected nodes */
protected void rlbDealer_Transferring(object sender, Telerik.Web.UI.RadListBoxTransferringEventArgs e)
{
    ArrayList tbResults = new ArrayList();
    RadTreeView treevview =(RadTreeView)rlbDealer.Items[0].FindControl("rtvDealersAvailable");
    foreach (RadTreeNode node in treevview.GetAllNodes())
    {
        if (node.Selected)
            tbResults.Add(node.Text);
    }
    foreach (string listitem in tbResults)
    {
        RadListBoxItem item = new RadListBoxItem();
        item.Text = listitem;
        rlbDealers.Items.Add(item);
    }
}

/* to select the child nodes of selected node*/
protected void rtvDealersAvailable_NodeClick(object sender, RadTreeNodeEventArgs e)
{
    RadTreeView rtvDealersAvailable = (RadTreeView)sender;
    RadTreeNode node = rtvDealersAvailable.SelectedNode;
    if (node.HasControls() == true)
    {
        foreach (RadTreeNode node1 in node.GetAllNodes())
        {
            node1.Selected = true;
        }

    }
}

Hope this will help you.
Thanks,
Shinu.

Hi Shinu!
thanks for your answer.
I've try your code but there's an issue that it's not possible to maintain highlight all the selected node(father and childs) and transfert them with one clik.
When i click on the father node only this is highlight and the child no.
do you have any suggestion?

Hi,

I suppose you need to highlight the parent on child node click.
C#:

protected void rtvDealersAvailable_NodeClick(object sender, RadTreeNodeEventArgs e)
{
    RadTreeView rtvDealersAvailable = (RadTreeView)sender;
    RadTreeNode node = rtvDealersAvailable.SelectedNode;
    if (node.HasControls() == true)
    {
        foreach (RadTreeNode node1 in node.GetAllNodes())
        {
            node1.Selected = true;
        }
    }
    if(node.Level!=0)
     node.ParentNode.Selected = true; // to highlight the parent of selected node.
}

Hope this will help you.
Thanks,
Shinu.

Hi
perhaps i didn't explain me well. I need to copy both parent and childs node from rtvDealersAvailable to rlbDealers. But i want to select parent and child node with one click on the parent node and view all the selected node highlight. AS you can see in the attach picture only the parent node is highlight.

Hi,
Problem-solved by using this javascript function

function selectFatherAndChildNodes(sender, eventArgs) {
            var node = eventArgs.get_node();
            var allnode = node.get_allNodes();
            var status = node.get_selected();
            for (var i = 0; i < allnode.length; i++) {
                allnode[i].set_selected(status);
            }
        }
