Displaying Formatted XML in an ASP.net Razor Web Page

A quick post for those looking to display a formatted XML document on an ASP.net Razor web page. The following code is in the controller and used to create the string to get passed through to the view. This example is based on displaying the information pulled from the Azure Management API as mentioned in previous blogs. The data is stored in a SQL Server database.

    Function ShowRawXML(serviceOperationId As String, subscriptionName As String) As ActionResult
        Dim model As New ShowRawXMLViewModel

        Dim op = (From o In _db.ServiceOperations
                  Where o.ServiceOperationId = serviceOperationId And o.Subscription.FriendlyName = subscriptionName
                  Select o).Single

        model.RawXML = vbCr & Server.HtmlEncode(op.RawXML)
        model.SubscriptionName = subscriptionName
        model.SubscriptionID = op.Subscription.SubscriptionID
        model.ServiceOperationID = serviceOperationId
        model.ServiceOperationType = op.Type.Name

        Return View(model)
    End Function

In the view, we are going to use the @Html.Raw function so we used the Server.HtmlEncode function to make it safe to display in HTML. Next we get to the razor view…

@ModelType AzureManager.Domain.ShowRawXMLViewModel

    ViewData("Title") = "ShowRawXML"
End Code

<h2>Subscription ID [@Model.SubscriptionID] @Model.SubscriptionName</h2>

<h3>Show Raw XML for Service Operation @Model.ServiceOperationID</h3>
<h3>Operation Type: @Model.ServiceOperationType</h3>


    @Html.ActionLink("Back to List", "ServiceOperations", New With {.Id = Model.SubscriptionName})

Here you notice we display the raw XML inside a <pre></pre> tag. This will preserve the white space in the string. More information on this here: HTML <pre> Tag


Getting an ASP.NET MVC Razor site into the cloud

Filed under: ASP.NET MVC, Azure, Learning — Tags: , , , , , — vbmagic @ 12:53 pm

I started to work on a web role to test out experiments with ADO.net code first and ASP.NET MVC 3 with Razor. Out of the box, VS 2010 does not support ASP.net MVC 3 so I created the Azure project, then added a ASP.NET MVC 3 project separately. I then added that MVC project to the Azure project as a web role. Clicked run and all seemed to work fine.

But as with all things Azure, if it works in the developer environment, don’t expect it to automatically work in the cloud.

It didn’t. But I was expecting that. It was a bit hard to track down what the problems were as it only manifested as a web role that never seemed to get started.

Once I had worked out that meant it was missing core components for the web site, I was pleasantly surprised was how easy it was to fix this.

On your MVC 3 project right click the project solution and then select “Add Deployable Dependencies”

Then click the “ASP.NET MVC” and the “ASP.NET Web Pages with Razor syntax” check boxes and click ok.

You will then find a directory added to your project called _bin_deployableAssemblies.

All I did after this was “Deploy” the Azure Project and after waiting for the project to deploy into the cloud, it all started ok and worked.

I wish all problems were as easy to solve as this 🙂
