Add the "does not begin with" and "does not end with" to the list of filter parameters

The problem was initially reproduced by TestStudio users. It can also be reproduced with a codedUI test where the editor is searched by its AutomationID.

Error Message:

Microsoft.VisualStudio.TestTools.UITest.Extension.UITestControlNotFoundException: The playback failed to find the control with the given search properties. Additional Details: 
TechnologyName:  'UIA'
ControlType:  'Text'
AutomationId:  'CellElement_2_1'

The problem will be fixed with Q3 2014 official version.

The problem occurs from 2014 Q2.  It should be resolved with lib version 2014.3.1319.

With R2 2016 RadGridView will introduce ValidationType property that indicates what type of validation input should be processed(INotifyDataErrorInfo, IDataErrorInfo, DataAnnotations).

Resolved with lib version 2014.2.0825.

Please provide a property that will allow a message to be displayed to users when RadGridView is empty. 
Some users perception is that the program is not working properly when there is no data in the grid view so displaying a user-friendly message can be a useful way of preventing inquires and complaints.

This problem is reproducible only in WPF and can be observed on both Row Context Menu and Header Context Menu QSF examples.

The fix will be available with Q2 2015 version.

GridViewCell.Errors - System.Collections.IEnumerable Errors { set; get; }

Errors collection always returns a collection of strings.  When using .NET 4.5 and INotifyDataErrorInfo the errors can be any type. In our case we are using a custom ValidationResult object that has different severity levels.

Because GridViewCell.Errors always returns strings and not the original underlying ValidationResult object our DataTemplate for ValidationResult is not applied.

Resolved with lib version 2014.2.714.
