I am trying to create a hotel booking calendar that selects the DateFrom and DateTo

I need to iterate through from the DateFrom to DateTo and display all these dates in the calendar, the code I have so far only selects the `DateFrom` and `DateTo` and displays them in the calendar as a label:

C#

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
   {
       foreach (DataRow dr in ds.Tables[0].Rows)
       {
           DateTime df = (DateTime)dr.Field<DateTime?>("DateFrom");
           DateTime dt = (DateTime)dr.Field<DateTime?>("DateTo");


           if (e.Day.Date == dt.Date)
           {
               Label lbl = new Label();
               lbl.BackColor = System.Drawing.Color.Gray;
               lbl.Text = "Booked From";
               e.Cell.Controls.Add(lbl);
            }

           if (e.Day.Date == df.Date)
           {
               Label lbl = new Label();
               lbl.BackColor = System.Drawing.Color.Gray;
               lbl.Text = "Booked To";
               e.Cell.Controls.Add(lbl);
           }
       }

The solution I am using in case somebody who needs this comes across this is:

C#

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
{
  foreach (DataRow dr in ds.Tables[0].Rows)
  {
    DateTime df = (DateTime)dr.Field<DateTime?>("DateFrom");
    DateTime dt = (DateTime)dr.Field<DateTime?>("DateTo");

    if (e.Day.Date == dt.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Booked From";
        e.Cell.Controls.Add(lbl);
     }

    if (e.Day.Date == df.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Booked To";
        e.Cell.Controls.Add(lbl);
    }

    //Added Code
    if(e.Day.Date > df.Date && e.Day.Date < dt.Date)
    {
        Label lbl = new Label();
        lbl.BackColor = System.Drawing.Color.Gray;
        lbl.Text = "Day inbetween";
        e.Cell.Controls.Add(lbl);
    }
}
