  Hi Ahncel,

  Ahncel

  *View Code

  @{Html.RenderAction("SideBar", "Home"); }

  Which view is this line of code in ? SideBar View or the other?

  I make a demo and put @{Html.RenderAction("SideBar", "Home"); } in Index View,when Index View is loading, it will jump to SideBar Action,and call _SideBar View.

  But I can't reproduce your issue.

  Maybe you could refer to this link:

  https://stackoverflow.com/questions/19272720/error-executing-child-request-for-handler-in-view

  https://stackoverflow.com/questions/18465059/error-executing-child-request-for-handler-system-web-mvc-httphandlerutilserver

  There are many factors that can cause errors.

  I think you could pay attention to:

  1.[HttpGet]

  2.return PartialView("_SideBar",clients)

  3.Get rid of the layout @{ Layout = null; } in the child view

  4... or other

  In addition, it seems that somewhere in the processing stack there is an issue. Press continue and the full error will be output onto the webpage.

  Easy to find once it got to this point.

  If you have any questions,please post more details.

  Best Regards.
