How to make optional parameter in partial view using asp.net MVC?

In this article we will discuss How to make optional parameter in partial view using asp.net MVC. We are using using partial view at many places with model. If some place no need of model that time we need to pass null.

Partial view with model parameter:

  @Html.Partial("_PartialLayout",@Model)

Partial view with null parameter:

Here I no need to pass parameter model parameter, condition is like that. So we need to do pass null and new ViewDataDictionary().

@Html.Partial("_PartialLayout", null, new ViewDataDictionary())
@model Post
@if (Model != null)
 {
  @Model.SomeProperty
 } 
 else
 {
  <div>
     no model passed
 </div>
}
