I have downloaded ajax toolkit and installed it sucessfully.

and put the following code


<div>
<asp:TextBox
ID="TextBox1"
runat="server"
width="300pt" />
<asp:ImageButton
ID="btnCalenderPopup"
Width="16" Height="16"
runat="server"
ImageUrl="~/images/calender.bmp"
CausesValidation="False" />
<ajaxToolkit:CalendarExtender
ID="CalendarExtender1"
runat="server"
TargetControlID="TextBox1"
PopupButtonID="btnCalenderPopup"
Format="dd/MM/yyyy" />

</div>



But I am getting this error. Pls check it...


*Error Creating Control - CalendarExtender1This control cannot be displayed because its TagPrefix is not registered in this Web Form.*

Hi Abhishek,

First put this before form
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="asp" %>
and then write this inside form
<form id="form1" runat="server">
<asp:ToolkitScriptManager ID="ToolkitScriptManager2" runat="server">
</asp:ToolkitScriptManager>

and now ur design code shud be like this

<div>
<asp:TextBox
ID="TextBox1"
runat="server"
width="300pt" />

<asp:ImageButton ID="btnCalenderPopup" Width="89px" Height="27px"
runat="server"
ImageUrl="~/images/calender.JPG"
CausesValidation="False" />
<asp:CalendarExtender ID="TextBox1_CalendarExtender" runat="server"
PopupButtonID="btnCalenderPopup" TargetControlID="TextBox1">
</asp:CalendarExtender>
</div>
</form>


Cheers
Emma
