Declare event in form2 for AddRow, subscribe to that event in form1, when button clicked on form2 and new row have to be added, form2 raises that event, so form1 handles it and shows it on DataGrid.

Tutorial for event implementation you can find here:

If I am understanding your question you need to do the following:

1. You need to create a click event for your 'Add' button that will add the new record to your database.
2. Once the record is added you can close your form and on your form close you can refresh the datagrid in Form1.

I do something similar to this in several of my applications. On Form1 when opening Form2 you can create something like this:

private void ShowForm2()
{
    DialogResult addResult = new Form2().ShowDialog();

    if (addResult == DialogResult.OK)
    {
        //your code to populate your datagrid
    }
}

Then on Form2 your Add button click

private void AddRecordButton_Click(object sender, EventArgs e)
{
    try
    {
       // code to add the record to your database
       //then use the DialogResult   OK
       DialogResult = DialogResult.OK
    }
    catch
    {
       //if it fails set DialogResult to Abort
       DialogResult = DialogResult.Abort
    }

}
