ArgumentNullException can be thrown when opening a RadOpenFileDialog in the following scenario: CustomPlaces contains the Desktop directory, InitialDirectory is also set to Desktop and ShowNetworkLocations is false.
System.Windows.Data Error: 8 : Cannot save value from target back to source. BindingExpression:Path=CurrentParentDirectory; DataItem='OpenFileDialogViewModel' (HashCode=57416810); target element is 'FileDialogsBreadcrumb' (Name='PART_PathNavigationPane'); target property is 'CurrentItem' (type 'Object') ArgumentNullException:'System.ArgumentNullException: Value cannot be null.

The following exception is thrown when a new file dialog is created on a separate thread and its ShowDialog method is invoked.
InvalidOperationException: "The calling thread cannot access this object because a different thread owns it."
This happens also if you define an ExplorerControl in any Window opened on another UI thread.
To work this around make sure that you use RadFileDialog and ExplorerControls only on the main UI thread. For example:
App.Current.Dispatcher.BeginInvoke(new Action(() =>
{
RadOpenFileDialog openFileDialog = new RadOpenFileDialog();
openFileDialog.ShowDialog();
}));
ArithmeticException is thrown on RadSaveFileDialog's ShowDialog call, when the device model profile of the OS (from the Color Management menu) is set to sRGB virtual device model profile.
The profile should be set through the Change system defaults menu. This setting is accessed by opening the Color Management menu in the OS, then select the Advanced tab, then click on Change system defaults... In the newly opened dialog click Advanced again and change the Device profile to sRGB virtual device model profile.
This is actually a bug in the WPF framework that is reported here.
The important part of the exception stacktrace is the following:

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type RadBreadcrumbBarItem
Note that also the context menu of the file should reflect the mode. Currently, the menu shows the default action based on the file extension as a bold text option. For example - "Open" or "Install". This is inconsistent with the default behavior where the file gets renamed (instead of opened). Ensure that the context menu bolding is updated accordingly.
Currently, the RadFileDialogs does not provide an API option for applying additional filtering of the already filtered files.
We could extend the filtering functionality of the RadFileDialogs control.
Entering such shared folder in breadccrumb might result in the folling: child folders of target folder are briefly visible
for some short period of time then breadcrumb and tree fallbacks selection to a parent folder.
An exception is thrown when the ShowNetworkLocations property is set to false.
