Step 1

Create a Web Part using Visual Studio 2013.

Step 2

Open the ascx (MyFirstWebPartUserControl.ascx) and design your UI. Here I have created Employee details information.

Step 3

Open the C# file (MyFirstWebPartUserControl.ascx.cs) and write your functionality. Once entering the Employee information, click the Save button; the employee details information is then added to the SharePoint list.

Step 4

Build and deploy your solution.

Step 5

Go to your SharePoint site and create one page under site pages. Add your web part to that page.
