Drag and Drop between Nodes

[Alan]

Hello

I am finding some difficulty with the drag and drop of nodes in the treeview.

I got a treeview with many number of nodes in different levels and I have enabled the properties for drag and drop in the treeview. To restrict some nodes order(position) not to change in the treeview, for those nodes I have set the allowdrop and allowdrag property to false. The problem is eventhough I set the property to false, it allows to drop in between the nodes so I could not make some nodes position to be same(static) always. Whereas this works for the older version of radControls(before prometheus).

Could you help me in this?

Thank you.

Hello Mark Leeds,

Setting AllowDrop to false of a Node will prevent other Nodes to be dropped onto it. Dropping between Nodes is not controlled in such a way.

However, you can hook to the OnClientNodeDropping event of the TreeView and depending on the drop position, the destination Node and its AllowDrop property you can cancel the event. In this way, you can achieve the desired functionality.

Please see these help articles for more information:

• OnClientNodeDropping
• RadTreeNode
