Question

I’m trying to pass a ViewData object from a master page to a view user control using the ViewDataDictionary.

The problem is the ViewDataDictionary is not returning any values in the view user control whichever way I try it.

The sample code below is using an anonymous object just for demonstration although neither this method or passing a ViewData object works.

Following is the RenderPartial helper method I’m trying to use:

<% Html.RenderPartial('/Views/Project/Projects.ascx', ViewData.Eval('Projects'), new ViewDataDictionary(new { Test = 'Mark' })); %> 

and in my view user control i do the following:

<%= Html.Encode(ViewData['Test']) %> 

Why does this not return anything?

Thanks for your help.

EDIT:

I’m able to pass and access the strongly typed model without any problems. it’s the ViewDataDictionary which I’m trying to use to pass say just a single value outside of the model…

Answer 1

Have you tried:

<% Html.RenderPartial('~/Views/Project/Projects.ascx', ViewData); %> 

Also have you verified ViewData[‘Test’] is in the ViewData before you are passing it? Also note that when passing your ViewData to a Partial Control that it is important to keep the Model the same.
