[Solved] contextMenus and webservice

[jim]

I want to populate data with webservice. but how can i add contextMenus for those new nodes(the context menus are different of parent node)?

Hi jim,

We had a small glitch with the RadTreeNodeData class - it did not contain any information for the node ContextMenuID. That will be fixed in the official service pack of the RadControls "Prometheus" suite scheduled for the next week.

Please, bear with us some more.

Hi guys,

Please, find attached the latest internal build of the RadControls "Prometheus" suite, having the glitch fixed.

Let me know your experience with it.

Hi Erjan,

I have started using the TreeView with a webservice and must say it works brilliantly and fast. The .ContextMenuID is also there, but when I try and retrieve the ID after webservice population it is empty, why?

The ContextMenu is attached, but there is no ID attached to the selectedNode.

Can you confirm this behaviour?

Hi Mark,

We missed the proper serialization of the RadTreeNodeData on the client, that's why it does not contain the information about the ContextMenuID. We already fixed that and the fix will be available in the next service pack of the RadControls "Prometheus" suite.

There is a workaround currently which you can use. It is the following:

• Define a client-side event handler to the OnClientNodePopulating property;
• Pass the node ContextMenuID to the context object;
• Get the ContextMenuID server-side from the context.

Please, find attached a rework of our WebService example, demonstrating that.

I hope this helps.

Hi Erjan,

Unfortunately the workaround will not work for me, as I need the ContextMenuID onNodeClick, but the ContextMenuID that I save in the OnClientNodePopulating method is the wrong ID as it is the nodes parent.

Can you give me an estimate as to when the service pack will be out?

Hi Mark,

I'm sorry I could not understand your scenario. Basically the workaround should work the same way as the actual control implementation.

We haven't determined the exact service pack release date yet, but it will be about two or three weeks from now. Anyways, I just prepared a preliminar fix for you. Please, find it attached.

Let me know if your application works fine now. If not, can you please, prepare a small running page that will demonstrate the problem so that we can find a possible fix or a workaround?

Hi Erjan,

The trial hotfix didn't seem to help. I opened a Support Ticket with a running example 117713.

It may be a simple matter of that I cannot do what I want this way. I am no expert at throwing javascript around and client/server-side objects.

Hi Mark,

Thanks to your project we found an omission in the RadTreeNode data serialization on postback. The bug is already fixed.

Thanks!
