The programming language is C# we are using wpf forms.

Hello, I would like to get my clear button to work. So when clear is click everything is clear not only the total, tax or subtotal but also the combox and the data grid. For the Delete button if the user selects a specific item it will be deleted and for the receipt button, it should create a pdf that contains the Name, Price, quantity, tax, total and subtotal. it is WPF forms. Also if you can create the user login part of the homework I would really like that.

I can upload the project to google drive if you would like.
