I have a dataGridView1 and the User can enter infos to it, then by clicking a button3 I want him to search for whatever he types in a textBox3 And to get a MessageBox saying if the string was found or not in the datagridview.

This is my code

```
private void button3_Click(object sender, EventArgs e)
    {
        bool j = false;
        foreach (DataGridViewRow rows in dataGridView1.Rows)
        {

            for (int i = 1; i < rows.Cells.Count; i++)
            {
                if(j == false)
                {
                    if (textBox3.Text == rows.Cells[i].Value.ToString())
                    {
                        j = true;
                    }
                }
                else
                {
                    break;
                }

            }

        }

        if (j == true)
        {
            MessageBox.Show("It exists!");
        }
        else
        {
            MessageBox.Show("It doesn't exist!!");
        }

    }

```
