Define Default Value to Date Fields in C Sharp

The below codes populate textboxes (IDs = StartDatePr and EndDatePr) on page load with default values:

protected void Page_Load(object sender, EventArgs e)

{if (!IsPostBack)

{

StartDatePr.Text = DateTime.Now.AddDays(-30).ToString("MM/dd/yyyy");

EndDatePr.Text = DateTime.Now.ToString("MM/dd/yyyy");

}

}
