Hi Oren,

Yes, the requested functionality is possible.

You should register the external dialog files of RadEditor so that you can modify the FileBrowser.ascx file, e.g.

<telerik:RadEditor runat="server" ExternalDialogsPath="~/EditorDialogs" ID="RadEditor1">
    <ImageManager ViewPaths="~/Images" UploadPaths="~/Images" DeletePaths="~/Images" />
</telerik:RadEditor>

After that open the \EditorDialogs\FileBrowser.ascx file, locate the RadFileExplorer control and attach the OnClientDelete function to its OnClientDelete event property, e.g.

<telerik:RadFileExplorer ID="RadFileExplorer1" OnClientDelete="OnClientDelete" Height="450px" Width="400px" TreePaneWidth="150px"
runat="Server" EnableOpenFile="false" AllowPaging="true" />
<script type="text/javascript">
function OnClientDelete(oExplorer, args)
{
 var item = args.get_item();
 
 if (item.isDirectory())
 {
  args.set_cancel(true);
  alert("You cannot delete directories");
 }
}
</script>

For your convenience I have attached a fully working project to my reply.

Thanks!! it works fine.
I have another related question:
I'm adding 2 folders for the users a user folder where he ca upload and store his clipart and a general folder for our clipart.
I've set the ImageManager.DeletePaths to the first directory and the ImageManager.ViewPaths to both folders, however the system still allows deleting from both directories. how can I prevent users from deleting from the general clipart directory?

Thanks

I fixed it, I had to set the view folder first and only then the delete folder. I had it vice versa...

Is it possible to disable the right-click context menu from renaming a folder? or disable the whole right click functionality from the File explorer?

thanks again

Hi Oren,

You can disable the context menu by opening the \EditorDialogs\FileBrowser.ascx file and setting the VisibleControls="AddressBox,Grid,Toolbar,TreeView" property in the RadFileExplorer control:

            <telerik:RadFileExplorer VisibleControls="AddressBox,Grid,Toolbar,TreeView" ID="RadFileExplorer1" Height="410px" Width="400px" TreePaneWidth="150px"
                runat="Server" EnableOpenFile="false" AllowPaging="true" />

Hi,
I find this thread and it is really helpful for me! But why does this way using javascript? Is that a good security performance? Thx!

Hello louis,

You can perform an additional server-side check and cancel the operation when a folder is deleting by using this approach:

I hope this helps.
