how to return a single item by its id in web matrix?

How can I query the database using Web Matrix to get a single item by passing the ID in from another page?

Note: I'm using partial pages for alot of my UI, these are just pages in webmatrix, using:

@RenderPage("/page_name.cshtml")

I'm trying to compose a <ul> from two tables and pages. A Services table which has an associated ServiceFeatures table. It WebMatrix it picks up the relationship by assigning a serviceID to the ServieFeatures table, that is the ServieId of the Services table.

So I have two pages to render the <ul> one _ServiceList.cshtml which has the following:

@{
var db = Database.Open("winmodb");
var servicesSql = "SELECT * FROM Services WHERE Featured = 'true'";
var services = db.Query(servicesSql);

}

<div id="service-list">
@foreach(var service in services) {        
    <h2>@s开发者_如何学运维ervice.Name</h2>
    <ul>
        @RenderPage("~/shared/_ServiceFeature.cshtml", @serviceId);
    </ul>
}

And inside of _ServiceFeature.cshtml I have the following.

   @{
   var db = Database.Open("database");        
   var serviceFeatureSql = "SELECT * FROM ServiceFeatures WHERE ServiceId = @0";       
   var serviceFeature = db.QuerySingle(serviceFeatureSql, serviceId);    
}

<li>@serviceFeature.Name</li>

But it's not working, and I'm not sure if I have to pass a variable or not. I know that serviceId dosen't exist in the current context, this is where I'm stuck.

In the _ServiceList page, your RenderPage call should look like this:

@RenderPage("~/shared/_ServiceFeature.cshtml", service.serviceId) 

In _ServiceFeature, you can obtain the value of the serviceId using Page[0]:

db.QuerySingle(serviceFeatureSql, Page[0]);

---

Parameters are passed in the PageData (non-dynamic) or Page (dynamic) properties:

@RenderPage("~/shared/_ServiceFeature.cshtml", new { serviceId });

In the partial page, you can write

db.QuerySingle(serviceFeatureSql, Page.serviceId);

In order to access parameters by name, you need to pass then as an anonymous type.
