Winforms - Show Datagrid selection in different window

Question

I have a datagrid in a window.

If I double click, I need to show the selected row in text boxes in a new window.

When I double click a row, I can display the new form right now.

How can I know what row was double clicked in the new window..

I cannot find a way for my "form2", which is the new window, to have access to the datagrid which sent it...

How can the form2 know..

What "topics" should I read to understand this? Is this related to Data Binding?

Thanks

Answer 1

define an event handler for CellDoubleClick or CellContentDoubleClick. In the event handler function do this.

    private void dataGridView1_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
    { 
    DataGridViewRow row = (DataGridViewRow) sender; //cast the sender object to DataGridViewRow
    Form2 newForm = new Form2(row);
    }

and in the Form2 constructor

    public class Form2 : Forms
    {
       private DataGridViewRow _row;

    public Form2(DataGridView row)
    {
        _row = row; // now you have a copy of the row in question
        txtFname.Text = _row.Cells[0].ToString(); 
        //row.Cells[0], row.Cells[1], row.Cells[n] will work here
    }
