I Have form 1 with 4 textboxes and 1 button, and I have form 2 which contains dataGridView, I want to add new row to the datagridview from the other form.

the problem is When I click on Add button it open the main form with empty datagridview and add the row alone there, what should I do to make the new row be added to the datagridview in original form with the rest of rows.

C#

Main frm = new Main();
            StockDBDataSet ds = new StockDBDataSet();
            DataRow obj = ds.Tables[0].NewRow();
            obj[0] = textBox1.Text;
            obj[1] = textBox2.Text;
            obj[2] = textBox4.Text;
            obj[3] = dateTimePicker1.Value;
            ds.Tables[0].Rows.Add(obj);
            ds.Tables[0].AcceptChanges();
            frm.dataGridView1.DataSource = null;
            frm.dataGridView1.DataSource = ds.Tables[0];
            this.Hide();
            frm.Show();

In your programm you are creating a new main form object instance.

public partial class Form1 : Form
{

Form2 frm2=new Form2();
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
frm2.AddNewRow();
frm2.Show();
}
}

public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}
public void AddNewRow()
{
dataGridView1.Rows.Add();
}
}

worked try this.

public partial class Form1 : Form
{

Form2 frm2=new Form2();
DataSet ds = new DataSet();

public Form1()
{
InitializeComponent();
ds.Tables.Add();
ds.Tables[0].Columns.Add();
ds.Tables[0].Columns.Add();
}

private void button1_Click(object sender, EventArgs e)
{

DataRow dr = ds.Tables[0].NewRow();
dr[0] = "1";
dr[1] = "3";
ds.Tables[0].Rows.Add(dr);
frm2.dataGridView1.DataSource = ds.Tables[0];
frm2.Show();
}

public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
}

}

form 2 contains grid.
