asp.net-mvc viewbag - How can I pass parameters to a partial view in mvc 4





parent model (4)


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>

I have a link like this:

 <a href='Member/MemberHome/Profile/Id'><span>Profile</span></a>

and when I click on this it will call this partial page:

 @{
    switch ((string)ViewBag.Details)
    {

        case "Profile":
        {
           @Html.Partial("_Profile"); break;
        }

    }
}

Partial page _Profile contains:

Html.Action("Action", "Controller", model.Paramter) 

Example:

@Html.Action("MemberProfile", "Member", new { id=1 })   // id is always changing

My doubt is that how can I pass this "Id" to model.parameter part?

My controllers are:

 public ActionResult MemberHome(string id)
    {
        ViewBag.Details = id;
        return View();
    }
  public ActionResult MemberProfile(int id = 0)
    {
        MemberData md = new Member().GetMemberProfile(id);
        return PartialView("_ProfilePage",md);
    }



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.




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,




(Here's a more detailed version of the existing answers.)

Create a folder called App_Code in the root of the MVC project if it doesn't already exist. In here, create an empty razor view and name it whatever you want:

Add @helpers and/or static methods to it as needed:

@helper ShowSomething()
{
    <span>Something</span>
}

@functions
{
    public static int CalculateSomething()
    {
        return 1;
    }
}

Then use them from your views by first accessing the shared view by name:

@Shared.ShowSomething()
@Shared.CalculateSomething()
