Maybe I'm doing this wrong but it works with the standard .Net SaveFileDialog. No matter how many filters I add or which FilterIndex I set, the last filter is always activated.

If I set .InitialDirectory to a network path, the Tree Navigation Pane shows multiple instances of the network path. I've collapsed several of them so you can see it more easily in the image. Am I missing a setting? Can this be prevented in the Directory Requesting sub?

I'd like to prevent the possibility of an end-user deleting or copying files while saving a file. Is this possible in the RadOpenFileDialog?

To reproduce: 

private void radButton1_Click(object sender, EventArgs e)
{
    RadOpenFileDialog fd = new RadOpenFileDialog();
    fd.ShowHiddenFiles = true;
    fd.ShowDialog();
}

Use the Demo application >> File Dialogs >> First Look example.  I have tested typing "\\DYORDANOLAP" and hitting Enter and it seems to navigate to the folder only after pressing Enter a second time:

Expected: In the Windows File Explorer, the user is navigated to the respective folder after the first time the user hits Enter.

In this case, by default hidden files/folders are not visible. When we hide a file/folder while the explorer control is visible, the hidden file/folder will still be present in the UI, thus allowing the user to navigate to it. 

Currently, the dialogs provide a way to restore the last open directory. The opened directory path will be stored in a private string field of the RadOpenFolderDialog instance. However, in other this to work, the dialogs require the following steps:

• The same dialog instance should be used every time you open the dialog.
• In order for the directory to be saved the directory should be opened. Clicking cancel or the X button won't save the directory.
• Closing the application and then opening it again, or generally when you create a new dialog instance, the last saved directory will get lost.

We could expose a mechanism to cache the last open directory outside of the dialogs, thus allowing you to restore the directory even when the application is closed.
