Part 20 - Add Edit Record using Partial View, JQuery and Bootstrap Modal

In this video you will find an Add/Edit record functionality using partial view and bootstrap modal (see example Create a popup using bootstrap). The concept is pretty much straight forward- First you click on edit record button then, a popup is displayed and you make some changes in it then, finally you submit the record.
For implementing this do what as shown in the video. Before starting anything, please create a project and give it a name "MVCTutorial" otherwise, you will get an error while replacing with below code.

#Controller Code

Add a controller named "Test" and replace everything with below code. In below code, you will find three methods
a) Index () : This method will return all employees records.
b) Index (EmployeeViewModel model): This method will insert and update employees record.
c) AddEditEmployee(int EmployeeId): This method will return a partial view containing the record of a particular employee. This method is called when we start editing an employee record. The employee record is displayed in modal(popup).
