I am very new to ASP.NET, and this question intrigues me cuz I am sure there is a simple solution.

To solve this question I made my own page that dynamically added DataGrid controls to the page then inserted the title, every 5 rows of the DataTable that populated the DataGrid. It got complex and messy, so that wasn't elegant enough.

I am sure it would be possible to declare a new class inherited from System.Web.UI.WebControls.DataGrid and you would modify either the method .RenderControl or the method .Render and change the contents of the string being fed to the HtmlTextWriter to force a custom [title] row  every nth row.

If you got fancy, you could probably put in a couple properties to define the HTML of the title row and the rows on which the title row should appear.

Would that be the right approach? If it is.. can someone post any code sample (vb.net if possible) that shows a webcontrol having it's contents modified when being rendered?
