    Hi,

    We are trying to create a mobile view of some forms which use Telerik controls for some elements, namely RadInput and RadInputMulti. All other form fields save when the form is posted back on mobile except for the Telerik based fields. When the page is posted back we are seeing a javascript error that reads 'Uncaught TypeError: Cannot read property 'PageRequestManager' of undefined', coming ScriptResource.axd at line 106. 

    Is there an issue with using these fields on mobile, and if so is there anything we can do to mitigate this issue and make things work?

    We are using version 2015.2.818.35 of the Telerik controls, on a SharePoint 2010 platform.

    Testing is happening in Chrome and Safari for iOS, although the solution needs to work on Android as well.

    Thanks for any help in advance.

    Ben

    Hello,

    This looks more like a compatibility issue between the ajax framework and sharepoint 2010 on mobile devices. The same problem can probably be experienced with any ajax control and not specifically Telerik inputs.
    The PageRequestManager is part of the MS Ajax framework used in the controls - it seems it is not initialized properly on postback and throws an exception.
    We also recommend to check if you have any ajax settings on the problematic page and if disabling them resolved the issue.
