Modularizing is always a good idea to simplify code. With the Extract to User Control feature, we have a powerful tool that will help us with this refactoring functionality.
Here we are going to show how to easily generate a user control from a section of code in our web page.
- Open our previous ASP.NET application or create a new one.
- If you created a new application, add a control and customize it to your liking.
- Open the
Site.Masterpage. - Go to the
divbody and select the<section>element surrounding it. - Right-click on the selected code and click on the Extract to User Control option.
- On the Save as dialog, assign the name
ListOfCategories.ascxand click on the OK button.
- Now we will need to move the
GetBookCategories()method from the code, as the related methods are not moved.
