Hi!

How do i send node to a webservice method?

I would like to send node to a webservice method for further processing. I use the NodeDropping event like this:

function

ServiceTree_NodeDropping(sender, eventArgs)
{
   
var destNode = eventArgs.get_destNode();
   
if(!destNode.get_allowDrop())
    {
        eventArgs.set_cancel(
true);
       
return;
    }
   
    // Call to webservice method
    MyService.MyMethod(destNode, eventArgs.get_sourceNodes());
}

What should my webservice mehod signature look like in this example, where i would like to send both a single Node and an array/list of node?

Best Regards,
Christian

Hello Christian,

You can create a new object and map treenode properties to it:

var param = {};
param.Text = node.get_text();
param.Value = node.get_value();

WebService.WebMethod(param);

Then you can use an IDictionary for the web service method.

public void WebMethod(IDictionary<string, object> param)
{
     string text = (string)param["Text"];
}

The same goes with the array - pass an array of objects to the web service method. Then use IEnumerable as the type of the web service method argument.

Best wishes,

Can you provide the code that is used to pass a RadTreeNodeData to the webservice when using load-on-demand for expanding?  The webservice signature is something like:

Public Shared Function GetTreeSubItems(ByVal node As RadTreeNodeData, ByVal context As ObjectAs RadTreeNodeData() 

How do I pass in a RadTreeNodeData from the clientside to the webservice?  Is there a private internal function that turns a clientside RadTreeNode to clientside RadTreeNodeData?
