    <p>I need to render a partialview to a string, and I am trying to convert a C# example to VB.Net, as I am stuck with that for this project.</p> <p>This is causing me a headache from these two problems:</p> <ol> <li>ObjectViewData - I can't figure out what that is</li> <li>RenderPartial is a sub, but seems to be used as a function - I don' get it</li> </ol> <p>I reference the MVCContrib.UI, so I don't need to convert that. But these two functions, I do need to convert:</p> <p>(from <a href="http://www.brightmix.com/blog/how-to-renderpartial-to-string-in-asp-net-mvc/" rel="nofollow noreferrer">brightmix.com</a>)</p> <pre><code>/// Static Method to render string - put somewhere of your choosing public static string RenderPartialToString(string userControl, object viewData, ControllerContext controllerContext) { HtmlHelper h = new HtmlHelper(new ViewContext(controllerContext, new WebFormView("omg"), null, null), new ViewPage()); var blockRenderer = new BlockRenderer(controllerContext.HttpContext); string s = blockRenderer.Capture( () =&gt; RenderPartialExtensions.RenderPartial(h, userControl, viewData) ); return s; } /// Your Controller method... public ActionResult MakeStringForMe() { var objectViewData = new objectViewData { SomeString = "Dude", SomeNumber = 1 }; string s = RenderPartialToString("~/Views/Controls/UserControl.ascx", objectViewData, this.ControllerContext); View(); } </code></pre> <p>Here is my attempt at converting it to VB.Net</p> <pre><code>'Static Method to render string - put somewhere of your choosing' Public Shared Function RenderPartialToString(ByVal userControl As String, ByVal viewData As Object, ByVal controllerContext As ControllerContext) As String Dim h As New HtmlHelper(New ViewContext(controllerContext, New WebFormView("omg"), Nothing, Nothing), New ViewPage()) Dim blockRenderer As New MvcContrib.UI.BlockRenderer(controllerContext.HttpContext) Dim s As String = blockRenderer.Capture(RenderPartialExtensions.RenderPartial(h, UserControl, viewData)) End Function Public Function MakeStringForMe() As ActionResult Dim objectViewData As objectViewData = New objectViewData With {.SomeString = "Dude", .SomeNumber = 1} Dim s As String = RenderPartialToString("~/Views/Controls/UserControl.ascx", objectViewData, Me.ControllerContext) View() End Function </code></pre> <p><a href="http://i43.tinypic.com/2cg1ves.png" rel="nofollow noreferrer">alt text http://i43.tinypic.com/2cg1ves.png</a></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
