Question

I am currently going nuts making a page to display the contents when an ID is passsed to it.
The code i have can be found below

 @{  
Layout = "~/_SiteLayout.cshtml";
Page.Title = "Home";
var db = Database.Open("StarterSite");
 var PageID  = UrlData[0]; 
 if (PageID.IsEmpty()) { 
     PageID = "1";
 } 
var pages = db.QuerySingle("SELECT * FROM PAGES WHERE Id = @0",PageID);

}

        <div class="productInfo">
            <h3>@pages.Body</h3>
            </div>

Basically what i am trying to get it to do is when you enter the url default/1 that the body of the page which has an id of 1 will appear and that if no querystring is given it will default to ID 1

When i run this i get an error with the line

@pages.Body

stating Exception Details: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot perform runtime binding on a null reference

the URL passed is http://localhost:20756/Default/1 and there is a page with an ID of 1 in the system

Answer 1

the exception in other words:

your runtime said:

“you gave me a query that did not
return anything, but want me to access
some data on that result … errm …
that’s not going to happen”

if this code runs in your default.cshtml, try removing “Default/” from your url …

note that PageID.IsEmpty() is not evaluating to true since UrlData[0] will probably contain "Default"
