I have created a web part for creating new list item using VS.

Web part has a DateTime Control.

If I click on Calendar icon then it does not render it, rather gives a server error.

enter image description here

I have included TagPrefix as follows-

<%@ Register TagPrefix="SharePoint" Namespace="Microsoft.SharePoint.WebControls" Assembly="Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c" %>

and control is placed as

<SharePoint:DateTimeControl ID="dtcStartDate" runat="server"  DateOnly="True" Calendar="ChineseLunar" />

Kindly help me resolve this problem.

  • Can you copy the full error message. Commented May 20, 2015 at 16:36
  • You should consider relative or absolute path when you put DatePickerFrameUrl !

Beware that $SPUrl is token known only in SharePoint Server editions and it is not available in SharePoint Foundation. Using $SPUrl in SharePoint Foundations throws an exception The expression prefix 'SPUrl' was not recognized

SharePoint Server:

<SharePoint:DateTimeControl runat="server" ID="date" DatePickerFrameUrl="<% $SPUrl:~sitecollection/_layouts/15/iframe.aspx %>" />

SharePoint Foundation:

<SharePoint:DateTimeControl runat="server" ID="date" DatePickerFrameUrl='<%# SPContext.Current.Web.ServerRelativeUrl + "/_layouts/15/iframe.aspx" %>' />

As SharePoint:DateTimeControl Crashes in SP2013 Webpart. Try below:

<SharePoint:DateTimeControl ID="dtStartdate" runat="server" DateOnly="true" DatePickerFrameUrl="<% $SPUrl:~sitecollection/_layouts/15/iframe.aspx %>" />

<SharePoint:DateTimeControl ID="dtControl" runat="server" DateOnly="true" DatePickerFrameUrl="../_layouts/15/iframe.aspx" />
