Hi,

For this to happen you can use the  OnClientContextMenuShown client function  by setting the

radFileExplorer.TreeView.OnClientContextMenuShown ="OnClientContextMenuShown" on serevr side logic

 

 

 

Client Script :

function OnClientContextMenuShown(oTreeView, args) {

var pathToItem = args.get_node().get_value();

var treeContextMenuItems = args.get_menu().get_allItems();

if (pathToItem == "/Root/") {

for (var i = 0; i < treeContextMenuItems.length; i++) {

var menuItem = treeContextMenuItems[i];

if (menuItem.get_value() == "Rename" || menuItem.get_value() == "Copy") {

menuItem.set_enabled(false);

}

}

}

}

Note : Replace the string  "/Root/" with your root folder name and the args.get_node().get_value();
will fetch you the name of the current selected node.

 

Hope this helps

Mani

but now if i want to not visible in the GridContextMenu?

i have this code but is wrong.

RadFileExplorer1.GridContextMenu.OnClientShown = "EliminarOpcionesEnMenu"

<script type="text/javascript">
        function EliminarOpcionesEnMenu(oTreeView, args) {
            var pathToItem = args.get_node().get_value();
            var treeContextMenuItems = args.get_menu().get_allItems();
          
                for (var i = 0; i < treeContextMenuItems.length; i++) {
                    var menuItem = treeContextMenuItems[i];
                    if (menuItem.get_value() == "Rename" || menuItem.get_value() == "Copy") {
                       menuItem.set_visible(false);
                    }
                }
          
        }
     </script>

Try this out

RadFileExplorer1.GridContextMenu.OnClientShown = "EliminarOpcionesEnMenu"

 

< script type="text/javascript">

 function EliminarOpcionesEnMenu(oTreeView, args) {

 var pathToItem = args.get_node().get_value();

 var treeContextMenuItems = args.get_menu().get_allItems();

  

for (var i = 0; i < treeContextMenuItems.length; i++) {

 var menuItem = treeContextMenuItems[i];

 if (menuItem.get_value() == "Rename" || menuItem.get_value() == "Copy") {

 menuItem.style.diplay ="none";

 }

 }
 
}
< /script>

Hi all:
This solution is almost exactly what I want, BUT, I want to pass to the function which folders specificially.  I don't want to hard code it in like the above solution ("/Root/").  Any further ideas??

Hi Terri-Lynn,

I am not quite sure I understand the exact scenario. The modifications discussed in this thread are regarding hiding the Rename for the root (top level) folder set to RadFileExplorer. If you need to apply this modification for multiple scenarios (or in a scenario where the root folder can be changed dynamically) you can use the following approach to dynamically access the path of the root node:

function OnClientContextMenuShown(oTreeView, args)
{
    var pathToItem = args.get_node().get_value();
    var rootNodes = oTreeView.get_nodes();

    var rootPaths = [];
    for (var i = 0; i < rootNodes.get_count(); i++) {
        rootPaths.push(rootNodes.getNode(i).get_value());
    }

    var treeContextMenuItems = args.get_menu().get_allItems();
    if (rootNodes.indexOf(pathToItem) > -1) {
        for (var i = 0; i < treeContextMenuItems.length; i++) {
            var menuItem = treeContextMenuItems[i];
            if (menuItem.get_value() == "Rename" || menuItem.get_value() == "Copy") {
                menuItem.set_enabled(false);
            }
        }
    }
}

I hope this helps.
