Hi All,

How can I disable dates in datepicker that are less than a particular date and handled in App.xaml for all datepickers. I used DisplayDateStart property. But, if user entered the date less than a particular date, I want to clear it. Please, let me know if it is possible.

A warning for you: you post some comment as a "solution". You should not do it. But by some weird reason, you even accepted this "answer" formally. This is already outrageous. And such things cannot help you; all you can get is some down-votes and abuse reports; those unpleasant things you don't want.

try this it is confirm code:
1. First add java script to head section

XML

<script type="text/javascript">
     function checkDate(sender, args) {
         if (sender._selectedDate < new Date()) {
             alert("You cannot select a day earlier than today!");
             sender._selectedDate = new Date();
             // set the date back to the current date
             sender._textbox.set_Value(sender._selectedDate.format(sender._format))
         }
     }
    </script>

2.then call it into date picker like this:

XML

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
   <asp:CalendarExtender ID="TextBox1_CalendarExtender"  OnClientDateSelectionChanged="checkDate" runat="server"
       TargetControlID="TextBox1">
   </asp:CalendarExtender>
   </form>

Its End:

I Also put all page code for better understating for you:

XML

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="testFinal.aspx.cs" Inherits="ArunHome_Design_testFinal" %>

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
 <script type="text/javascript">
     function checkDate(sender, args) {
         if (sender._selectedDate < new Date()) {
             alert("You cannot select a day earlier than today!");
             sender._selectedDate = new Date();
             // set the date back to the current date
             sender._textbox.set_Value(sender._selectedDate.format(sender._format))
         }
     }
    </script>



</head>

<body>
    <form id="form1" runat="server">
 <%-- <iframe src="http://www.cricinfo.com" height="700px" width="700px"></iframe>--%>



    <asp:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
    </asp:ToolkitScriptManager>
    <br />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:CalendarExtender ID="TextBox1_CalendarExtender"  OnClientDateSelectionChanged="checkDate" runat="server"
        TargetControlID="TextBox1">
    </asp:CalendarExtender>
    </form>


</body>
</html>
