How to Display information from a ListView into a TextBox using WPF

Question

Hi I'm creating a car app to display a list of cars in a ListView and I want the users to be able to Click on the list item and it display in the TextBox. At the moment it works but it uses the ToString method and I cant format it at all, I would like to add a new line at the end of each record, so each property is on its own line, and generally have more control of how it displays. Is there a better way of doing it then what I have done. Ill include all my code so you have everything. I'm usually very average at asking questions so any advice with my question asking and my code would be greatly appreciated. Thanks..

class BaseCarClass
            {
                private string carBrand;
                private string carModel;
                private int yearModel;
                private int carPrice;



                //CarBrand Property
                public string CarBrand
                {
                    get
                    {
                        return carBrand;
                    }//end get
                    set
                    {
                        carBrand = value;
                    }//end set
                }//end property CarBrand


                public string CarModel

                       return carModel;
                    }
                    set
                    {
                        carModel = value;
                    }

                        carPrice = value;
                    }
                }
                //BaseClass Constructor

                    CarPrice = car_price;
                }//end base class constructor

                public string space { get { return " "; } }

                public string GetCar

From the current design you simple replace your space (" ") with "\n" to achieve the multiple records for each property. So you will be doing all your formatting withing GetCar property. If you need more control over each property, you can redesign your view to something like this. But that will depend on what your final requirements are.

Wow that's was so obvious can't believe I missed it. Can you only put properties inside the ToString override or can I some how put all the formatting inside the ToString without using a separate property to create a space/newline?

asb Over a year ago

There is no restriction that you can only put properties. You can (if you wish) put all the formatting logic in there.

All I did in the end was return string.Format("All the details and formatting in here") Thanks for the help though, I just missed the simple stuff after looking at it too long.

You just need to bind the Text property of Textbox to the SelectedItem of ListView. No need for the handler.

Text="{Binding Path=SelectedItem, ElementName=carListDisplay}"

Good luck with your succeeding assignments.
