Prevent users from deleting folders

[Oren Halevi]

Is there a way to allow users to delete files but prevent them from deleting folders in the imagemanager?

thanks

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

[Rumen]

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:

• Set the ExternalDialogPath property
• Get reference to the RadFileExplorer control and attach a handler to the RadFileExplorer's OnItemCommand event
• Check the name of the performed operation as shown in this help page. If the operation is "DeleteDirectory" then cancel the it by setting e.Cancel=true

I hope this helps.
