RepeaterItem.DataItem will not cast to DataRowView? [C#]

[fizzled]

I'm attempting to use the following code to conditionally drop a link inside a Repeater, and from what I've read everywhere, I should be able to cast the RepeaterItem.DataItem to a DataRowView to access the current row of information so I can decide if I need a link or not. Does anyone see why this isn't working?

 

private void rptrActiveBlogs_ItemDataBound (object Sender, RepeaterItemEventArgs e) {

 if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem)) {
   [color=red]DataRowView drvCurrent = (DataRowView) e.Item.DataItem;[/color]
   Literal litAuthor = (Literal) e.Item.FindControl("litBlogAuthor");

   if (drvCurrent["AuthorEmail"].ToString().Length == 0) {
     litAuthor.Text = drvCurrent["AuthorName"].ToString();
   } else {
     litAuthor.Text = "<a href=\"mailto:" + drvCurrent["AuthorEmail"].ToString() + "\" title=\"Contact " + drvCurrent["AuthorName"].ToString() + "\">" + drvCurrent["AuthorName"].ToString() + "</a>";
   }

 }

}

 

The error occurs on the line in red. The error specifically says "Specified cast is not valid."
