Question

I am using ajax calendar extender for ‘From date’ and ‘To date’ text box, I have to disable To date previous date or dates lesser than selected ‘From date’. I can see many posts using range validation. How I can disable the dates without any message to user?

Answer 1

First add .dll – RJS.Web.WebControl.PopCalendar.Net.2008.dll

Then add source code:

<asp:TextBox ID="DepartureDate" runat="server"></asp:TextBox>
&nbsp;&nbsp;&nbsp;
      <rjs:PopCalendar ID="PopCalendar1" runat="server" Control="DepartureDate" 
            Format="mm dd yyyy" 
            InvalidDateMessage="The date value entered is invalid." RequiredDate="True" 
            RequiredDateMessage="You must enter a date value." From-Date="" SelectWeekend="True" 

            />
    <br />
    <br />
    <br />
    <asp:TextBox ID="ReturnDate" runat="server"></asp:TextBox>
&nbsp;&nbsp;&nbsp;&nbsp;
     <rjs:PopCalendar ID="myReturnCal" runat="server" Control="ReturnDate" 
            Format="mm dd yyyy" 
            InvalidDateMessage="The date value entered is invalid." RequiredDate="True" 
            RequiredDateMessage="You must enter a date value." 
            From-Control="DepartureDate" From-Date="" From-Increment="1" 
            />
    <br />
      <asp:Label ID="Results" runat="server"></asp:Label>
        <rjs:PopCalendarMessageContainer ID="PopCalMessagesForDeparture" runat="server" 
            Calendar="myDepartureCal" />
        <rjs:PopCalendarMessageContainer ID="PopCalMessagesForReturn" runat="server" 
            Calendar="myReturnCal" />
