  • Pradeep,

    Create a TextChanged EventHandler in your password textbox and write the below code.

    private void TextBox_TextChanged(object sender, TextChangedEventArgs e)
                TextBox textBox = sender as TextBox;
                if (textBox != null)
                    string text = textBox.Text;
                    if (text.Length > 5)

    Please mark this answer if this is helpful.
