ASP.NET

Create a Web Forms application using a user interface similar to the one shown below. However feel free to modify the layout to allow for better usability, if desired. 
All server-side code should be in C#

 
Required Features:
1.	Name/Value pairs are to be entered into the upper textbox. This textbox is used for adding and filtering Name/Value pairs.
2.	When the ‘Add’ button is pressed the Name/Value pair in the textbox is validated, and then if it passes validation it is added to the listbox below. The Name/Value pair entry format is shown below:
3.	<name> = <value>
4.	Where <name> is the name portion of the pair, and <value> is the value portion of the pair. Only valid Name/Value pairs can be added. Names and Values can contain only alpha-numeric characters. The equal-sign is used to delimit the pair, spaces before and/or after the equal-sign may be entered as padding at the end-users discretion. 
5.	When the ‘Sort by Name’ button is pressed the list will be sorted ascending by Name.
6.	When the ‘Sort by Value’ button is pressed the list will be sorted ascending by Value.
7.	When the ‘Delete’ button is pressed all selected items in the listbox will be deleted.
Optional Features 
The following features are a test option and may not be required, please refer to the job description to see if it is a requirement
1.	When the ‘Filter’ button is pressed, only the Name/Value pairs that match the filter criteria will be shown in the listbox. The search criteria will be taken from the textbox. 

Filters have the following format (and are similar to the Name/Value format): 

<type> = <value> 

Where <type> is either Name or Value, and <value> is a string used for matching against the given type.  
2.	When the ‘Clear Filter’ button is pressed all of the Name/Value pairs will be shown in the listbox.

The model backing the 'MVCDBContext' context has changed since the database was created. Consider using Code First Migrations to update the database (http://go.microsoft.com/fwlink/?LinkId=238269).
