Refresh datagridview records from another form

I have dataGridView1 in form1 but for inserting in it I'm using form2 which have save button (that provides insert into datagridview1) to which I'm trying to set - refresh or select * from so I dont need any refresh button in form1 whenever I want to show up just all the recors. Is there any way to achieve that?

Thanks much for your time.

You can use Form.DialogResult to achieve this.

In your insert form, after saving data to database:

DbContext.SaveChanges();
MessageBox.Show("Successfully saved.");
DialogResult = System.Windows.Forms.DialogResult.Yes;

and In your grid form:

Frm_NewData newData = new Frm_NewData();
if (newData.ShowDialog() == System.Windows.Forms.DialogResult.Yes)
{
     RefreshGrid();
}

You can use delegate.. For example :

Form1 :

private void btnForm1_Click(object sender, System.EventArgs e)
{

// Create an instance of form 2
    Form2 form2 = new Form2();

    // Create an instance of the delegate
    form2.passControl = new Form2.PassControl(PassData);

    // Show form 2
    form2.Show();
}

private void PassData(object sender)
{
    // Set de text of the textbox to the value of the textbox of form 2
    txtForm1.Text = ((TextBox)sender).Text;
}

Form 2 :

public class Form2 : System.Windows.Forms.Form
{
    // Define delegate
    public delegate void PassControl(object sender);

    // Create instance (null)
    public PassControl passControl;

    private void btnForm2_Click(object sender, System.EventArgs e)
    {
        if (passControl != null)
        {
            passControl(txtForm2);
        {
        this.Hide();
    }
}

I hope this helps..
