ASP.net GridView Shortcut

When dealing with Strongly Typed datasets on the ASP.net GridView 2.0, I found myself writing one too many lines of code like this:

<asp:TemplateField HeaderText="Category">
  <ItemTemplate>
  <%# DataBinder.Eval(
    ((System.Data.DataRowView) Container.DataItem).Row,
   "CategoryRow.CategoryName") %>
  </ItemTemplate>
<asp:TemplateField>

Solution?

<asp:TemplateField HeaderText="Category">
  <ItemTemplate>
   <%# EvalEx(Container.DataItem, "CategoryRow.CategoryName") %>
  </ItemTemplate>
<asp:TemplateField>

protected object EvalEx(object DataItem, string Expression)
{
 return DataBinder.Eval(((DataRowView) DataItem).Row, Expression);
}
