Editing Options

Updated over 6 months ago

As of R1 2020 SP1 all file dialogs and the ExplorerControl offer the EditingOptions property. It determines how the files and folders in the ExplorerControl can be edited. Setting EditingOptions will determine which edit operations can be performed via keyboard keys and "NewFolder" button.

Note that the shell context menu and drag and drop operations are handled separately.

The available EditingOptions are listed below:

Editing Option	Description
None	Editing is not allowed.
Cut	Cut is enabled.
Copy	Copy is enabled.
Paste	Paste is enabled.
Delete	Delete is enabled.
Rename	Rename is enabled.
NewFolder	New folder is enabled.
All	All options in the menu are available.

Set multiple EditinOptions limitations

C#

            RadOpenFolderDialog openFolderDialog = new RadOpenFolderDialog();
            openFolderDialog.EditingOptions = Telerik.WinControls.FileDialogs.EditingOptions.All;
            openFolderDialog.EditingOptions ^= (EditingOptions.NewFolder | EditingOptions.Rename);
            openFolderDialog.ShowDialog();

VB.NET

        Dim openFolderDialog As RadOpenFolderDialog = New RadOpenFolderDialog()
        openFolderDialog.EditingOptions = Telerik.WinControls.FileDialogs.EditingOptions.All
        openFolderDialog.EditingOptions = openFolderDialog.EditingOptions Xor (EditingOptions.NewFolder Or EditingOptions.Rename)
        openFolderDialog.ShowDialog()

Even though you specify the EditingOptions, the end-user is still allowed to drag and drop the files. If you want to disable drag and drop operations you should set explicitly the IsDragDropEnabled property of the ExplorerControl to false.

Disable drag and drop operations

C#

    openFolderDialog.OpenFolderDialogForm.ExplorerControl.IsDragDropEnabled = false;    

VB.NET

	openFolderDialog.OpenFolderDialogForm.ExplorerControl.IsDragDropEnabled = False

You cannot modify files/folders context menu but you can choose to cancel its opening. You can, however, modify the empty space context menu items as follows:

Modify ShellContextMenu

C#

           private void RadForm_Load(object sender, EventArgs e)
        {
            RadOpenFolderDialog openFolderDialog = new RadOpenFolderDialog();
            openFolderDialog.OpenFolderDialogForm.ExplorerControl.ShellContextMenuOpening += ExplorerControl_ShellContextMenuOpening;
        }

        private void ExplorerControl_ShellContextMenuOpening(object sender, Telerik.WinControls.FileDialogs.ContextMenuOpeningEventArgs e)
        {
            e.Cancel = true;

            if (e.IsOpeningOnEmptySpace)
            {
                e.Cancel = false;
                e.ShortContextMenuOptions = ShortContextMenuOptions.NewFolder | ShortContextMenuOptions.View;
            }
        }     

VB.NET

	     Private Sub RadForm_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        Dim openFolderDialog As RadOpenFolderDialog = New RadOpenFolderDialog()
        AddHandler openFolderDialog.OpenFolderDialogForm.ExplorerControl.ShellContextMenuOpening, AddressOf ExplorerControl_ShellContextMenuOpening
    End Sub

    Private Sub ExplorerControl_ShellContextMenuOpening(ByVal sender As Object, ByVal e As Telerik.WinControls.FileDialogs.ContextMenuOpeningEventArgs)
        e.Cancel = True

        If e.IsOpeningOnEmptySpace Then
            e.Cancel = False
            e.ShortContextMenuOptions = ShortContextMenuOptions.NewFolder Or ShortContextMenuOptions.View
        End If
    End Sub
