Expose an event that allows you to cancel the navigation to a folder. For example, if you enter an address in the breadcrumb, click the back button, or select a directory in the navigation tree, then you should be able to cancel the navigation.

This can be done via a new event that have a Cancel property in its arguments, for example.

The naming shown here is not mandatory.

It would be nice to have some additional public properties and commands for ExplorerControl.  For example:

• Boolean properties to show/hide the first two rows (containing the breadcrumbs, new folder button, layout combo box, etc.).
• Search command or public SearchText property.
• Cancellable OnNavigating event.
• Navigation tree "RootDirectory" property, which would replace the top-level "This PC" node.

Thanks for your consideration!

Hello.

I've created buttons that are bound to FileDialogCommands for sending commands to an ExplorerControl, as shown here:

https://docs.telerik.com/devtools/wpf/controls/radfiledialogs/features/commands

 

Everything works when the ExplorerControl is visible.  However, if the ExplorerControl's Visibility is set to Collapsed (which I need based on a condition), the Command bindings on the buttons throw the below error:

System.NullReferenceException: Object reference not set to an instance of an object.
   at Telerik.Windows.Controls.FileDialogs.ExplorerControl.CanExecuteHelper(Object sender)

 

The UserControl that hosts the ExplorerControl is being imported through MEF.  I don't know if that's a factor.

Either way, it looks like a null check might be needed for the InternalViewModel property.

Can you please add the ability to select (and scroll into view) a file/folder in the RadFileDialog by keyboard? i.e. when focused within the files section of the dialog, typing 's' should scroll to the first file starting with 's' and select it.

All the Win32 and WPF file dialogs support this.

Show the actual image when the layout of the main pane is set to Medium, Large and Extra Large Icons.

The error message appears after you do several operations with the dialog and then call the Directory.Move() method. The message is "Access to the path <path> is denied".

This is reproducible only with display language of the Windows set to a language different than English. It was originally reproduced with French.

If you set the initial directory to a network dir (ex: \\MyPcName\SharedFolder2\MyFiles), and open the dialog, initially the correct folder is loaded. However, if you wait several seconds without doing anything, the currently opened directory automatically changes to the root "Network" dir.

The contents of the Path Navigation Pane and Main Pane are not synced with the selection inside the Tree Navigation Pane when a local drive is shared through a remote desktop connection.

This behavior differs from the standard MS FileDialogs, where the expand arrow is not visible for such folders. 

The items inside the Tree Navigation Pane are not sorted in the same way as the native MS dialog. In our OpenFolderDialog when there is a file or folder name which starts with underscore "_" the file/folder is placed at the bottom of the tree navigation view. Looking at the tree from the MS dialog it is placed at the top.

In the Main Pane, the items are sorted correctly.

TextSearch navigation in the Main Pane does not work. If you press letter "a" the first folder with Name starting with "a" should be selected.
This needs to work in alll layouts including Details which uses RadGridView.

To reproduce this behavior you need the following settings.

- Set the display language of your Windows to Italian.
- Use a RadOpenFileDialog.
- Set its Filter. For example, you can filter to show only Excel files.
- Change the layout type to Details.

In this case the folders in the opened direction disappears.

Provide built-in support for the following combinations:

• Move to the previous folder:  Backspace or Alt+Left Arrow combination
• Move to the next folder: Alt+Right Arrow combination
• Change layout: Ctrl + Mousewheel combination

Drag & Drop between ExplorerControl and Windows Explorer does not work

For example Filter is "XAML CS Files (*.xaml.cs)|*.xaml.cs"

MS Win32 OpenFileDialog filter files correctly to show only xaml.cs files.

RadOpenFile/SaveFileDialog does not show the xaml.cs files which is wrong.

<telerik:RadDropDownButton DropDownWidth="400" DropDownHeight="400" VerticalAlignment="Center" Content="Dialog Button">
            <telerik:RadDropDownButton.DropDownContent>
                <dialogs:ExplorerControl Layout="Details"/>
            </telerik:RadDropDownButton.DropDownContent>
        </telerik:RadDropDownButton>

When the DropDown is opened Exception in FileBrowserGridView.cs is thrown.

ExplorerControl is in DropDownContent  of DropDownButton.

Selecting multiple files in the explorer is not possible.

ExplorerControl or FileDialog is opened with 

 StyleManager.ApplicationTheme = new Windows8TouchTheme();

On load exception is thrown:

 "Cannot find resource named 'BreadCrumbBarItemCustomStyle'.  Resource names are case sensitive"

RadOpenFileDialog or RadSaveFileDialog with Filter, for example 

  fileDialog.Filter = "Excel Worksheets|*.xlsx;*.xls|All Files|*.*";
   fileDialog.FilterIndex = 1;

This should filter the files in MainPane on load to xls files only (index is 1-based). However, filter is not applied on load - regression in R3 2018.

Currently RadFileDialogs do not provide such tooltips when hovering files and folders.

Check the attached image for clarification.
