Hi all,

I have two forms (Form1 & Form2).

Form1 contains a DataGridView control and Add button.
Form2 contains TextBoxes & save Button.

Here is my running forms
1st: Form1 will appear when click Add button
2nd: Form2 will appear here adding text to text boxes and when I click the save button it's saved to database and Form1 still stays there.

My question is this: I want to show existing Form ie Form1 with updating data and dont want to show a new Form1.

I hope you understand the concept.

Please help me out

You just need to use it as:

C#

Form1 m_frm = new Form1();
private void button_add_Click(object sender, EventArgs e)
{
    m_frm.Show();
}

and in Form 1 you need to handle the closing event:

C#

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
  e.Cancel = true;
  this.Hide();
}
