Prevent entering button event more than one time

I am using simple asp:Button to save a text box content to DB only once.

protected void btnSave_Click(object sender, EventArgs e)
{
  If(txtMessage.text != string.Empty)
  {
    // Insert into DB Method
    txtMessage.Text = string.Empty;
  }
}

The problem is when I double click the button, the text box won't be cleared, and the debugger enters the condition, therefore saves the content twice

Any help?

Save the last button click time and compare it when handling the click

something like:

    TimeSpan LastClick = DateTime.Now.TimeOfDay;
    private void button1_Click(object sender, EventArgs e)
    {
        lock (this)
        {
            if (DateTime.Now.TimeOfDay.Subtract(LastClick).TotalMilliseconds < 500)
                return;
        }
        LastClick = DateTime.Now.TimeOfDay;
        if(txtMessage.text != string.Empty)
        {
          // Insert into DB Method
              txtMessage.Text = string.Empty;
        }
    }
