Asp.net-mvc – passing viewdata to asp.net mvc masterpages

asp.net-mvcmaster-pagesviewdata

I'm trying to pass ViewData to my asp.net mvc masterpage for an mvc usercontrol that I keep on a masterpage. For example, I created a dropdownlist of names as an mvc usercontrol and I put that in my masterpage.

The problem I am running into is passing the ViewData to the masterpage. I found this article from Microsoft which has a decent solution but I was wondering if there are other "better" solutions out there. The thing I don't like about the solution in the link is that I have to change every controller to inherit from a new controller class.

Edit: The problem I am looking at is the fact that if I place a user control in my masterpage that relies on ViewData, I have to REPEATEDLY include that ViewData for every single page that uses said masterpage. It's possible the solution in the link above is the best solution but I was hoping there were other alternatives.

The master page already has access to the ViewData. If you want strongly typed access to it, you need to do two things:

Put the master page stuff in a base class (e.g. CommonViewData)
Have you master page inherit from the generic ViewMasterPage<> class:
" %>

If I understand your question, you are trying to pass ViewData into the user control. A user control is essentially a partial view, so you would do this:

<% Html.RenderPartial("someUserControl.ascx", viewData); %>

Now in your usercontrol, ViewData will be whatever you passed in...

From the readme word doc for RC1 (not indexed by google)

ASP.NET Compiler Post-Build Step

Currently, errors within a view file are not detected until run time. To let you detect these errors at compile time, ASP.NET MVC projects now include an MvcBuildViews property, which is disabled by default. To enable this property, open the project file and set the MvcBuildViews property to true, as shown in the following example:

<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
    <MvcBuildViews>true</MvcBuildViews>
  </PropertyGroup>

Note Enabling this feature adds some overhead to the build time.

You can update projects that were created with previous releases of MVC to include build-time validation of views by performing the following steps:

Open the project file in a text editor.
Add the following element under the top-most <PropertyGroup> element: <MvcBuildViews>true</MvcBuildViews>
At the end of the project file, uncomment the <Target Name="AfterBuild"> element and modify it to match the following:

<Target Name="AfterBuild" Condition="'$(MvcBuildViews)'=='true'">
    <AspNetCompiler VirtualPath="temp" PhysicalPath="$(ProjectDir)\..\$(ProjectName)" />
</Target>
