Pass value from one form to another form in c#

Question

I have to pass id from one form to another from in C#.

I am not able to do this.

The C# code is:

private void btnedit_Click(obje

Make a property in AddInvoice:

public long CellValue { get; set }

Assign to it:

private void btnedit_Click(object sender, EventArgs e)
{
    foreach (DataGridViewRow a in dataGridViewUnPaidList.Rows)
    {
        if (a.Cells[0].Value != null)
        {
            AddInvoice ad = new AddInvoice();
            ad.CellValue = Convert.ToInt64(a.Cells[1].Value);
            ad.Show();

            NonPaideData non = new NonPaideData();
            non.Hide();
        }
        else
        {
            MessageBox.Show("Now Row Is Selected");
        }
    }

And just use it in AddInvoice as CellValue.

Oh, and if that's actually the code, I think you probably meant this.Hide(); instead of creating a new NonPaideData and hiding that.
