Adding AjaxLoadingPanel to Treeview at node level

[Jerry]

Hello,

I have a radTreeView that has many nodes and sub-nodes. 
I want to add a AjaxLoadingPanel so it will display horizontally with the "+" being selected by the user.
Is this possible?

Thank you,
Jerry

Hello Jerry,

I would like to clarify that the RadTreeView does have a default animation that is shown next to the node's expand icon while the request is handled. Please find attached a sample project that implements server side call back scenario. For testing purposes I added System.Threading.Thread.Sleep(3000) that will cause a delay for 3 seconds so you can watch the animation and simulate loading lots of sub nodes .

Hi Boyan,

Thank you that example helped.  Within my tree view there is a node that will be populated using html.  It creates a list box with many items.  This node still has the "+" next to it even though it is the last node, how can I stop it from showing the "+"?

Thank you

Hello,

As far as I understand you are using the RadTreeView1_NodeExpand event handler in order to load the nodes on demand. In the attached sample project all nodes that are loaded on demand have ExpandMode property set to TreeNodeExpandMode.ServerSideCallBack. This means that all of them will have plus sign and will load nodes on demand if you click this sign. An easy and convenient way of avoiding this behavior is simply not to set ExpandMode  for your last node.
