c# ".datasource" not showing in the box

Question

Whenever I type the .DataSource it keeps having red on the bottom or having an error:

'ListView' does not contain a defenition for 'DataSource' and no extension method 'DataSource' accepting a first argument of type 'ListView' could be found (are you missing a using directive or an assembly reference?)

public Form4()
{
    InitializeComponent();

    lstProductsChosen.DataSource = products;
}

What should I do? Do I need to add reference?

You should have an error message when you hover over the red line on the bottom. What is it? and what type is `lstProductsChosen` ? It seems that this type does not have a property `DataSource` — Mong Zhu, Mar 08 '17 at 10:17
When I hover it says "'ListView' does not contain a defenition for 'DataSource' and no extension method 'DataSource' accepting a first argument of type 'ListView' could be found (are you missing a using directive or an assembly reference?)" — Stance19, Mar 08 '17 at 10:26
It says "form", more likely it's winforms, `ListView` in winforms doesn't have such property (perhaps you create a wrong project, shouldn't it be wpf?). — Sinatr, Mar 08 '17 at 10:27
Then why do you expect [System.Windows.Forms.ListView](https://msdn.microsoft.com/en-us/library/system.windows.forms.listview(v=vs.110).aspx) to have `DataSource`. Are you trying some tutorial code or what? — Sinatr, Mar 08 '17 at 10:28
Im trying to learn this tutorial on youtube. https://www.youtube.com/watch?v=99LWDWmSAqM it's working on him — Stance19, Mar 08 '17 at 10:31
It's another control called `ListBox` (not `ListView`) in this tutorial. — Sinatr, Mar 08 '17 at 10:33

ListView does not have a DataSource property.

ListBox has one. If you use a ListBox instead your code should work.

If you are using WPF you will find a Simple ListView data binding example behind the link.

If you are using WinForms then please check this short and consice answer by Hans Passant
