Show contextmenu when hovering on node instead of right-click

[Tommy]

I implemented the context menu for the treeview and everything works fine.  No my client wants me to show the context menu when hovering vs making the user rightclick, like the HoverMenu is in the Ajax Control Toolkit

http://www.asp.net/AJAX/AjaxControlToolkit/Samples/HoverMenu/HoverMenu.aspx

Is there another way to open the ContextMenu?   Hopefully there is a Javascript function that I can call to show it for each node.  

thanks

Any ideas?

I successfully implemented the AJAX Control Toolkit Hover extender in the NodeTemplate, and my client likes it.  However, I would still like to get the convext menu to display when hovering over a node, vs having to rightclick - I believe that is a cleaner solution in the long run.

does anyone have any ideas on this?

Hi Tommy,

You can subscribe to the OnClientMouseOver event and show the context menu in its handler as shown below:

<script type="text/javascript">
function onMouseOverHandler(sender, e)
{
    sender.showNodeContextMenu(e.get_node(), e.get_domEvent());
}
</script>

All the best,

Is it possible to trigger the node's context menu using a button or imagebutton control within the <NodeTemplate> tags?

I've an image button that I'd like to use within the node template to trigger the context menu, rather than right clicking. So far I've managed to make it so you can left click the node to trigger the menu handing 'OnClientNodeClicking' with this:

function ShowNodeContextMenu(sender, e) {
    e.set_cancel(true);
    sender.showNodeContextMenu(e.get_node(), e.get_domEvent());
}

Hi Matthew,

Please check this demo - it demonstrates how to open context menu while hovering elements.

That doesn't work unfortunatly. I can use the function in that demo (showMenu(e))to make the context menu appear when clicking a link button within the '<NodeTemplate>', however none of the items in the menu function, the 'OnClientContextMenuItemClicking' event for the radTree doesn't fire.

I think I need some way of triggering the 'showNodeContextMenu' function instead, when left clicking on a control within the <NodeTemplate>.


In an ideal world, there needs to be a 'Targets' collection within the RadTree's '<ContextMenu>' markup, so I can specify controls within the nodetemplate that trigger a menu.

Hi Matthew,

Could you please send us the exact definition of your treeview? Thanks
