    public bool Validations()
    {
        if (string.IsNullOrEmpty(Textbox.Text))
        {
            MessageBox.Show(" Error ");
            return false;
        }
        else
        {
            // your code 
        }
    }

private void button1_Click(object sender, EventArgs e)

{

        if (!Validations())
            return;

    }

Try using ErrorProvider. It may help.

private void button1_Click(object sender, EventArgs e)
{
    // check if something is wrong
    errorProvider1.SetError(textBox1,"Some Error!");
}
