AjaxControlToolkit CalendarExtender Control not working in my website

I' using the AjaxControlToolkit CalendarExtender in my web site but after uploading it does how show the calendar control. I have registered the control on the page itself. The page postback when I click the image on which I applied the control开发者_运维百科.

What can be the reason of this?

Check whether you added ToolkitscriptManager in your page, which is in AjaxToolkit

If you are using an ImageButton to show the calendar, then use ajax control toolkit and put these controls

<asp:ToolkitScriptManager runat="server" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    <asp:ImageButton ID="ImageButton1" runat="server" 
                     ImageUrl="calIcon.jpg" />
    <asp:CalendarExtender ID="CalendarExtender1" TargetControlID="TextBox1" 
                          PopupButtonID="ImageButton1" runat="server">
        </asp:CalendarExtender>

If you are still getting the page postback when clicking the ImageButton, you can add onClientClick='return false;' to the imageButton

<asp:ImageButton ID="ImageButton1" runat="server" 
                 ImageUrl="calIcon.jpg" 
                 OnClientClick="return false;" />

Drag and place Script manager at top of the ajax control or at top of the form.

As you said that ajax calender works fine on local but when you uploaded it it started creating problems following are the workarounds give them a try.

1. Check that whether you uploaded the ajax toolkit dll on the server or not.

2. secondly make sure that you uploaded updated web.config file.

   let me know if its helpful otherwise i will try finding other workarounds
