将数据从一个窗体上的DataGridView显示到另一窗体上的TextBoxes中

Question

I have two forms. ShoppingBasketForm.cs and EditBasketPopup.cs .

ShoppingBasketForm.cs displays a shopping basket in a DataGridView called dataGridBasket which is bound to a seperate List<OrderItem>OrderItems which comes from my OrderItem class. This can be added to by filling in the provided text boxes/numericUpDowns on the page Product Name Quantity and LatestPrice and then clicking the Add button btnAdd . It also has the ability to remove data from the selected row by clicking the Remove button btnRemove .

I'm now trying to implement an Edit button btnEdit where once clicked, it instantiates the EditBasketPopup form. On this form there are the three text boxes/ numeric up downs displayed again ProductName Quantity and LatestPrice .

How do I take the data from the selected row on the dataGridBasket (User cannot select single cells) and use that to fill the three text boxes when the user activates the btnEdit click event?

I tried creating a properties inside the EditBasketPopup.cs to hold the data from the first form, but was unsure how to extract the data from the selected row in the dataGridBasket in string form and also came across the problem of needing the individual data from each cell in the row, seeing as they are bound to different properties.

I obviously don't have much example code for this question as it's a theory as to how rather than why but if you need anything just let me know.

@Harry Sweetman ok first to get the selected element of your datagridview you can make something like this:

 //recover the view row
 DataGridViewRow drv = (DataGridViewRow)dataGridBasket.Current;

 //if the row is not empty => basket was selected in the dataGridView
 if (drv.Cells[0].Value != null)
 {
      //Here we get the first cell selected let say the name is like the id:
      string idBasketToEdit = drv.Cells[0].Value.ToString().Clone().ToString();

      //Now we instantiate the form EditBasketPopoup, but sending the selected basket as a parameter                  
       frmEdit = new EditBasketPopoup(idBasketToEdit);
       frmEdicion.Name = "Edit basket";
       frmEdicion.ShowDialog();         
 }

Also you need to have a form constructor in EditBasketPopup.cs with a Basket parameter like this:

    public EditBasketPopup(string idBasket)
    {
        InitializeComponent();
        Basket b = control.GetBasket(idBasket);

        //You set the form boxes:
        txtProductName.Text = b.ProductName;
        txtLatestPrice.Text = b.LatestPrice;
        txtQuantity.Text = b.Quantity;
    }

Finally let s suppose you have a controller (Ex. BasketController) were you have some logic. Here it 's supposed that you search the Basket you want to edit on the collection that it 's binding your datagridview (dataGridBasket).

public Basket GetBasket(string idBasket)
{
    try
    {
        //basketCollection is the one that you use to bind dataGridBasket
        return basketCollection.Find(x => x.idBasket.Equals(idBasket));
    }
    catch (Exception ex)
    {
        throw ex;
    }
}
