Release LIB 2021.2.809 (9 Aug 2021)
FileDialog with ExpandToCurrentDirectory set to false and a network location set as initial directory.
On Load, Breadcrumb shows only Network node but it should actually show the full path to the requested folder. Then this leads to inability to navigate upward with buttons next to breadcrumb bar.

A COMException with error message 'Exception from HRESULT: 0x80270000' is thrown when canceling the delete operation of a locked file. The operation needs to be invoked by pressing the Delete key of the keyboard - deleting the file by using the context menu works as expected.

Add an API that allows you to access the columns of the corresponding FileBrowserGridView control (representing the Details layout) so you can add different settings. Or alternatively provide some property abstraction to propagate properties from the file dialogs API to the internal RadGridView columns API.

Some files that can be seen in the Windows Explorer are missing from the ExplorerControl of the file dialogs. This happens because of a silent ArgumentOutOfRangeException thrown for a corrupted file that doesn't have a "Date Modified" attribute set. This breaks the loading of the following files in the directory.

Here are the exception details:

System.ArgumentOutOfRangeException: Not a valid Win32 FileTime.
Parameter name: fileTime
   at System.DateTime.FromFileTimeUtc(Int64 fileTime)
   at System.IO.FileSystemInfo.get_LastWriteTimeUtc()
   at System.IO.FileSystemInfo.get_LastWriteTime()
   at Telerik.Windows.Controls.FileDialogs.FileSystemInfoWrapper..ctor(FileSystemInfoWrapperFactoryBase factory, FileSystemInfo fileSystemInfo)
   at Telerik.Windows.Controls.FileDialogs.FileInfoWrapper..ctor(FileSystemInfoWrapperFactoryBase factory, FileInfo info)

   at Telerik.Windows.Controls.FileDialogs.DirectoryInfoWrapper.LoadFiles(DirectoryInfo directoryInfo)

Like in MS Win 32 OpenFileDialog - thumbnails with preview or details about the selected file.

Check the attached images for better clarification.

Currently, showing a dialog can take 10-20 seconds when started in DEBUG mode. 

And 3-5 seconds RELEASE mode. Improve the loading time.

A little way to speed up is to set ExpandToCurrentDirectory to False.

Currently, when there is an existing file with the same FileName as the chosen from the user, a dialog is shown asking for confirmation. We should provide a way to skip the showing of this dialog.

Setting the InitialDirectory property of the FileDialog to a folder with a huge large number of folders/items/files inside will significantly delay the loading process.
