HOW-TO
Prevent users from deleting folders in the File Browser dialogs

DESCRIPTION
Sometimes it is needed to allow users to delete files but prevent them from deleting folders in the File Browser dialogs. The solution below demonstrates how to implement this functionality.

SOLUTION
Here are the steps on how to disable the folder deletion in the File Browser dialogs of RadEditor:
1) 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>

2) Open the \EditorDialogs\FileBrowser.ascx file, locate the <RadFileExplorer> control and attach the OnClientDelete function to the 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>
