Hello,

This is what I would like:

C#

void DayRender(Object source, DayRenderEventArgs e) 
      {
if ((e.Day.Date <= ArrivalDate.AddDays(_Notice)) 
            || (e.Day.Date >= Convert.ToDateTime("20/May/2016")) && (e.Day.Date <=              Convert.ToDateTime("25/May/2016"))
            || (e.Day.Date >= Convert.ToDateTime("1/June/2016")) && (e.Day.Date <= Convert.ToDateTime("05/June/2016")))
        {
            e.Day.IsSelectable = false;
            e.Cell.Font.Strikeout = true;
            e.Cell.BackColor = System.Drawing.Color.Aqua;
        }
}

However I have reached here and I am now stuck.
The date values are coming to the reader from a database.

C#

void DayRender(Object source, DayRenderEventArgs e) 
      {
       using (SqlConnection connection = new SqlConnection(
               connectionString))
    {
        connection.Open();

        SqlCommand command = new SqlCommand(queryString, connection);
        SqlDataReader reader = command.ExecuteReader();
        while (reader.Read())
        {
           
        }
    }
}

What I have tried:

C#

using (SqlConnection connection = new SqlConnection(
           connectionString))
{
    connection.Open();
 
    SqlCommand command = new SqlCommand(queryString, connection);
    SqlDataReader reader = command.ExecuteReader();
    while (reader.Read())
    {
 
    }
}

Put code in what I have tried in a code block. Don't repeat the same thing in that section.

Don't write hard-coded values in code and don't convert constant from strings if you don't need to. Well, learn good coding practice.

Get the values from reader and replace it with the hardcoded values.

try this...................

C#

// We need this namespace
using System.Drawing;
 
public partial class DefaultCS : System.Web.UI.Page
{
  protected void Calendar1_DayRender(object sender, System.Web.UI.WebControls.DayRenderEventArgs e)
  {
    // Select all dates in the past
    if (e.Day.Date < System.DateTime.Today)
    {           
      // Disable date
      e.Day.IsSelectable = false;
      // Change color of disabled date
      e.Cell.ForeColor = Color.Gray;
    } 
 
  }
}

"ASP.NET">ASPX
<asp:Calendar ID="Calendar1" runat="server" ondayrender="Calendar1_DayRender"> </asp:Calendar>

CodeBehind

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)
  {
       if (e.Day.Date.CompareTo(DateTime.Today) < 0)
      {
          e.Day.IsSelectable = false;
      }
   }
