Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn

I have a datagrid called studentAddList which is combined by 2 tables. Now I have a reportviewer called ReportViewer1. They are both placed on the same page.
