View 2 RepliesI would like to wrap a RenderPartial in a JsonResult so that my jQuery can handle placement/positioning of the html data based on additional Json parameters.
e.g. {html: <string returned from RenderPartial>, typeofdata: 1}
After Googling, it seems that the only way to do this is a workaround that hijacks HttpContext in order to spit the PartialViewResult into a string. However, this seems like it would break testability.
Is JsonResult not intended to be used with RenderPartial?
Alternatively, I could set typeofdata as a parameter of the model, and have the PartialView render it as a hidden field, then have jQuery look for it. What is a better way to generate the data that I need?
