Telerik 'RadTreeView' equivalent for ASP.NET 'TreeView'

[Xorv]

Hi Admin,

For the follwing code (asp.net Treeview), please give the telerik equivalent.

 

 

 

 

foreach (DataRow row in territories.Tables[0].Rows)
            {
                RadTreeNode newNode = new RadTreeNode(row["terr_rpt_grp_ttl"].ToString(), row["terr_rpt_grp"].ToString());
                newNode.PopulateOnDemand = true;
                newNode.SelectAction = TreeNodeSelectAction.Expand;
                node.ChildNodes.Add(newNode);
            }
        }

 

The markup defined for the asp.net TreeView is:-

<asp:TreeView Runat="Server" OnTreeNodePopulate="Node_Populate" ID="tvwauthors">

<Nodes>

<asp:TreeNode Text="ALL" PopulateOnDemand= "true" Value="0"/>

</Nodes>

</asp:TreeView>

  Please help regarding this. Just the telerik equivalent. (For ex. PopulateOnDemand, TreeNodeSelectionAction.Expand etc etc)

Thanks a lot

Hello,

You can easily customize the action when clicking the node, by attaching the 'OnClientNodeClicked' event to RadTreeView instead of SelectAction. For example the following client code shows how to expand/collapse the node when clicking the node.

JS:

function OnClientNodeClicked(sender, args)
  {
   args.get_node().set_expanded(!args.get_node().get_expanded());
  }

Telerik RadTreeView supports "Load-On-Demand" feature that allows child nodes to be added on the fly as parent nodes are expanded.
