Question

I have a datagrid with data and when I call dataGridView1_CellDoubleClick i want to fill data from datagrif to the form. There is a code :

public Product something {get; set;}

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e){
int id = (int)dataGridView1.SelectedRows[0].Cells[0].Value;
something = Podatci.GetproductByID(id);

FrmNewForm a = new FrmNewForm();
a.Show();

and logicly when i open a new form it is empty

How to access objects like textboxes from form that is open

Answer 1

You can pass something to a new constructor of the form and show it there:

Add to the form:

public FrmNewForm(SomethingClass something) : this()
{
    txtSomething1.Text = something.Something1;
    // etc.
}

When you create it:

FrmNewForm a = new FrmNewForm(something);
