Here is an extension method that will convert an object to a ViewDataDictionary.

public static ViewDataDictionary ToViewDataDictionary(this object values)
{
    var dictionary = new ViewDataDictionary();
    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(values))
    {
        dictionary.Add(property.Name, property.GetValue(values));
    }
    return dictionary;
}

You can then use it in your view like so:

@Html.Partial("_MyPartial", new
{
    Property1 = "Value1",
    Property2 = "Value2"
}.ToViewDataDictionary())

Which is much nicer than the new ViewDataDictionary { { "Property1", "Value1" } , { "Property2", "Value2" }} syntax.

Then in your partial view, you can use ViewBag to access the properties from a dynamic object rather than indexed properties, e.g.

<p>@ViewBag.Property1</p>
<p>@ViewBag.Property2</p>

Your question is hard to understand  but if I m getting the gist  you simply have some value in your main view that you want to access in a partial being rendered in that view   If you just render a partial with just the partial name    Html Partial   SomePartial     It will actually pass your model as an implicit parameter  the same as if you were to call    Html Partial   SomePartial   Model    Now  in order for your partial to actually be able to use this  though  it too needs to have a defined model  for example    model Namespace To Your Model   Html Action  MemberProfile    Member   new   id   Model Id      Alternatively  if you re dealing with a value that s not on your view s model  it s in the ViewBag or a value generated in the view itself somehow  then you can pass a ViewDataDictionary   Html Partial   SomePartial   new ViewDataDictionary      id   someInteger         And then    Html Action  MemberProfile    Member   new   id   ViewData  id        As with the model  Razor will implicitly pass your partial the view s ViewData by default  so if you had ViewBag Id in your view  then you can reference the same thing in your partial

For Asp Net core you better use   lt partial name   MyPartialView  model  MyModel    gt    So for example   foreach  var item in Model        lt partial name   MyItemView  model  item    gt

One of The Shortest method i found for single value while i was searching for myself  is just passing single string and setting string as model in view like this   In your Partial calling side   Html Partial  ParitalAction    String data to pass to partial     And then binding the model with Partial View like this    model string   and the using its value in Partial View like this   Model   You can also play with other datatypes like array  int or more complex data types like IDictionary or something else   Hope it helps
