Issue
Date picker on the Calendar control stops working after setting the Date and Time format to use 'Thai (Thailand)' on the Calendar control and Anonymous Access is enabled on the View and Form.
Error Code
From a network trace captured on the browser Developer Tools, you will see a 500 error on the CalendarAJAXCall.ashx request and inspecting the request shows this error is returned:
No Anti-Cross Site Request Forgery cookie found in request
Under the Console tab, there is a Uncaught SyntaxError: Unexpected token '<' error"
Resolution
Here are the workarounds available:
1. Don't enable Anonymous Access on both the View and Form.
2. Follow the steps below:
a. Make a backup of the K2 SmartForms Designer and Runtime web.config files located in the below locations:
- %PROGRAMFILES%K2K2 smartforms Designer
- %PROGRAMFILES%K2K2 smartforms Runtime
b. Edit the web.config and add this setting under the <appSettings> node:
<add key="AntiXSRF.IgnoreFilePathList" value="/Runtime/CalendarAJAXCall.ashx;" />
c. Save the changes.
d. Perform an IISRESET.
Additional Information
For workaround #2, this is specific for the Calendar control only and will keep the rest of the K2 site secure.
