Disabling context menu items and upload buttons

[Joe]

I need to disable a certain context menu item (upload) and disable the upload button from the toolbar. 

I found this code to disable the toolbar upload function (and it works)

           Dim toolBar As RadToolBar = RadFileExplorer1.ToolBar

           ' Remove commands from the ToolBar control; 

           Dim i As Integer = 0

           While i < toolBar.Items.Count

               If toolBar.Items(i).Value = "Delete" Then

                   toolBar.Items.RemoveAt(i)

                   ' Next item 

                   Continue While

 

               ElseIf toolBar.Items(i).Value = "Upload" Then

                   toolBar.Items.RemoveAt(i)

                   ' Next item 

                   Continue While

               End If

 

               ' Next item 

               i += 1

           End While

Is there similar code to disable the context menu item (upload) in the code behind? I want to control this based on user login as I will use an IF statement to check the login name.

Thanks,
Joe

Hi Joe,

By design, RadFileExplorer enables the upload functionality if the current selected folder (or its parent folder(s)) is listed in the UploadPaths property. If upload permissions is not provided for the specific folder the Upload button on the toolbar and the context menu items will not be rendered at all.

The recommended approach to disable Upload button and context menus according to the logged user is to modify the UploadPaths property.

If you need to manually remove the context menu items you can use the following code:

Dim treeViewContextMenu As RadContextMenu = fileExplorer.TreeView.ContextMenus(0)
       ' Remove commands from the TreeView's ContextMenus control;
       i = 0
       While i < treeViewContextMenu.Items.Count
           If treeViewContextMenu.Items(i).Value = "Delete" Then
               treeViewContextMenu.Items.RemoveAt(i)
               ' Next item
               Continue While

           ElseIf treeViewContextMenu.Items(i).Value = "Upload" Then
               treeViewContextMenu.Items.RemoveAt(i)
               ' Next item
               Continue While
           End If

           ' Next item
           i += 1
       End While



       Dim gridContextMenu As RadContextMenu = fileExplorer.GridContextMenu
       ' Remove commands from the GridContextMenu control;

       i = 0
       While i < gridContextMenu.Items.Count
           If gridContextMenu.Items(i).Value = "Delete" Then
               gridContextMenu.Items.RemoveAt(i)
               ' Next item
               Continue While

           ElseIf gridContextMenu.Items(i).Value = "Upload" Then
               gridContextMenu.Items.RemoveAt(i)
               ' Next item
               Continue While
           End If

           ' Next item
           i += 1
       End While

A example of how to manually disable Delete and Upload commands is available in the following KB article:
