Hi friends,

I've a popup.aspx file that I want to display when I click the radTreeNode.
I am programmatically loading the nodes and their individual urls.

Below is the code snippet of another C# code that does this.

if (collection.rows.Count > 0)
{
    ScanNode = new RadTreeNode("View Scan: " + scan.CratedDate.ToShortDateString(), ScanID.ToString());
    SetNavigationOnNode(ScanNode , User.GetApplicationPath() + "/Imaging/Popup.aspx? <QuerySting Variable and their values> "&Image=" + ImageID);
    proceedingNode.Nodes.Add(proceedingScanNode);
}

SetNavigationOnNode
is a function and looks something like this:

private void SetNavigationOnNode(RadTreeNode node, string url)
{
    if (needPopupJS)
        node.Attributes.Add("onclick", GetRadWindowJS(url));
    else
        node.NavigateUrl = url;
}


Everything is fine but I want to open it us as pop up rather new window.

Thanks,
-Aarsh

Hello,

I would recommend you to use a single instance of RadWindow control for popup window on your page and load different page based on the selected node. You can declare an handler for OnClientNodeClicked event instead of setting "onclick" as attribute for the node.

//markup code
<telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientNodeClicked="ClientNodeClicked">
          ............
</telerik:RadTreeView>

//JavaScript
function NodeClientClicked(sender, args) {
            var nodeText = args.get_node().get_text();
            var oWnd = $find("<%= RadWindow1.ClientID %>");
            oWnd.show();
            oWnd.setSize(400, 400);
            oWnd.setUrl(nodeText);
        }

Please find attached a project that implements the described approach to achieve the desired functionality.
