Hello,

I have a an application where I'm attempting to have users select a date from a datepicker control, however, I would like to prevent users from selecting a previous date.

My *. aspx file code follows
-----------------------
   <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
         
          <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
     
     
 &nbsp;
          <asp:Calendar ID="Calendar1" runat="server" BackColor="#FFFFCC"
              BorderColor="#FFCC66" BorderWidth="1px" DayNameFormat="Shortest"
              Font-Names="Verdana" Font-Size="8pt" ForeColor="#663399" Height="200px"
              onselectionchanged="Calendar1_SelectionChanged" ShowGridLines="True"
              Width="220px" Visible="false">
              <SelectedDayStyle BackColor="#CCCCFF" Font-Bold="True" />
              <SelectorStyle BackColor="#FFCC66" />
              <TodayDayStyle BackColor="#FFCC66" ForeColor="White" />
              <OtherMonthDayStyle ForeColor="#CC9966" />
              <NextPrevStyle Font-Size="9pt" ForeColor="#FFFFCC" />
              <DayHeaderStyle BackColor="#FFCC66" Font-Bold="True" Height="1px" />
              <TitleStyle BackColor="#990000" Font-Bold="True" Font-Size="9pt"
                  ForeColor="#FFFFCC" />
          </asp:Calendar>
     
          <br />
     
      <asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">PickDate...</asp:LinkButton>
------------

My codebehind follows:

------------
protected void Page_Load(object sender, EventArgs e)
        {
            TextBox1.Text = DateTime.Today.ToString("MM/dd/yyyy");


        }




        protected void Calendar1_SelectionChanged(object sender, EventArgs e)
        {



            DateTime dt = System.DateTime.Now;
            DateTime dt2 = System.DateTime.Now;
            String dt2 = TextBox1.Text;

            if ((System.DateTime)dt2 <= dt)

                 //Convert.ToDateTime(myDateTimeString);

            {
                Label1.Text = "You can not pick a date earlier than today's date";

            }

            else
                TextBox1.Text = Calendar1.SelectedDate.ToShortDateString();


            Calendar1.Visible = false;
         

        }

       


        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            Calendar1.Visible = true;
 
        }
    -------------

ANY help would be greatly appreciated.

hi,

try this jquery

$("#datepicker").datepicker({ minDate: +0 });

or you can disable the previous dates

protected void Calendar1_DayRender(object sender, DayRenderEventArgs e)

    {

        if (e.Day.Date < DateTime.Now.Date)

        {

            e.Day.IsSelectable = false;

            e.Cell.ForeColor = System.Drawing.Color.Gray;

        }

    }

Open in new window

dexterrajesh,

Thank you for your reply.

However, I don't understand your suggestion for jquery.

Can you be more specific or point me to where examples of this coding exists?

Thank you in advance.

minDate tells jQuery to set the minimum date for selection. all dates less than min date will be disabled
