Difference between visual webpart & webpart

What is the visual web part ? 

A Visual Web Part is a type of Web Part that can be added to a SharePoint page to display custom content. Visual Web Parts are created using Visual Studio, and they are essentially custom controls that can be added to a SharePoint page like any other Web Part. Visual Web Parts can be used to display a variety of content, such as data from a database, information from a third-party service, or custom HTML, CSS, and JavaScript. They are a useful way to extend the functionality of a SharePoint site and to create custom user interfaces.

What is the web part ?

A Web Part is a reusable component that can be added to a Web page. Web Parts are a feature of Microsoft SharePoint and are also available in other web platforms. Web Parts can be used to display a variety of content, such as data from a database, information from a third-party service, or custom HTML, CSS, and JavaScript. Web Parts are often used to customize the appearance and functionality of a SharePoint site or other web page. They can be added, deleted, or modified by site administrators or users with appropriate permissions. Web Parts can be connected to each other, so that changes to one Web Part can affect the behavior of other Web Parts on the same page.

Difference between visual webpart & webpart.

A Visual Web Part is a type of Web Part that is created using Visual Studio and that can be added to a SharePoint page. A Visual Web Part is essentially a custom control that can be used to display a variety of content, such as data from a database, information from a third-party service, or custom HTML, CSS, and JavaScript.

A regular Web Part, on the other hand, is a reusable component that can be added to a Web page to display a variety of content. Regular Web Parts are not necessarily created using Visual Studio and may not have the same level of customization as Visual Web Parts.

In general, Visual Web Parts are more flexible and powerful than regular Web Parts, as they allow for more advanced customization and integration with SharePoint and other systems. However, they may require more development expertise to create and maintain. Regular Web Parts, on the other hand, may be easier to use and require less development effort, but may be less flexible and customizable.

• Enter the URL of the SharePoint site where you want to create the Visual Web Part.
• In the next screen, select whether you want to deploy the Visual Web Part to the farm or to a specific site.
• Visual Studio will create a new project with a default Visual Web Part.
• To customize the Visual Web Part, you can edit the code in the .ascx file to add HTML, CSS, and JavaScript, or you can use the Visual Studio designer to create a custom user interface.
• When you are finished, build the project and deploy the Visual Web Part to SharePoint.

To create a regular Web Part in SharePoint, you can do the following:

• Go to the page where you want to add the Web Part.
