Question

I’m having a bit of problem with casting and datagrids. I have a LINQ to SQL query:

var contents = from content in context.Contents
               join contenttype in context.ContentTypes on content.ContentTypeID equals contenttype.ContentTypeID
               select new { content, contenttype };

and then that gets put into a datagrid (not all of the data, only select columns such as content.ContentID etc).

The problem is that when I try and get the selected row, I cannot. I have the following code:

Console.WriteLine((Content)dataGrid1.SelectedItem);

which fails due to the fact that the type is both Content and ContentType – is there a way around this? The error I get is:

Unable to cast object of type '<>f__AnonymousType0`2[iAdvert_Desktop.Content,iAdvert_Desktop.ContentType]' to type 'iAdvert_Desktop.Content'.

If I just write the SelectedItem I get: { content = iAdvert_Desktop.Content, contenttype = iAdvert_Desktop.ContentType } – is there a way I can do something like: (Content)dataGrid1.SelectedItem['Content'];?
