使用datagridview中的数据以不同的形式填充文本框

Question

I'm trying to populate data from a DataGridView into TextBoxes which are on a different form . I can populate TextBoxes that are on the same form as the DataGridView . I'm not sure on how to reference the other form? My code :

var value = dgvInfo.Rows[e.RowIndex].Cells["Description"].Value;

if (value != null)
{
    txtDescription.Text = value.ToString();
}

EDIT 1: The possible duplicate question deals with passing data from one TextBox to another. In my question it is passing data from a DataGridView to a TextBox .

Answer 1

Pass Value as constructor parameter to destination form (for example Form4 ):

private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
    Form4 fr = new Form4(dgvInfo.Rows[e.RowIndex].Cells["Description"].Value.ToString());
    fr.ShowDialog();
}       

And in the destination form:

public Form4(string p)
{
    InitializeComponent();
    txtDescription.Text = p;
}

To pass more than one value to another form you should use a List like this:

private void button1_Click(object sender, EventArgs e)
{
    List<string> lst = new List<string>();

    foreach (DataGridViewRow row in dgvInfo.SelectedRows)
    {
        var Value = row.Cells["Description"].Value.ToString();
        if (!string.IsNullOrWhiteSpace(Value))
        {
            lst.Add(Value);
        }
    }
    Form4 fr = new Form4(lst);
    fr.ShowDialog();
}

And then in destination form:

public Form4(List<string> p)
{
    InitializeComponent();
    txtDescription.Text = p[0];
    textBox1.Text = p[1];
}
