Here is another way to do it if you want to use ViewData: @Html.Partial(“~/PathToYourView.cshtml”, null, new ViewDataDictionary { { “VariableName”, “some value” } }) And to retrieve the passed in values: @{ string valuePassedIn = this.ViewData.ContainsKey(“VariableName”) ? this.ViewData[“VariableName”].ToString() : string.Empty; }
There is built-in ajax helpers in ASP.NET MVC which can cover the basic scenarios. You need to install and refer jquery.unobtrusive-ajax JavaScript library ( + jQuery dependency).
