I've been successful in creating GridView controls programically using c#. I'd like to take advantage of using the clientmode=predicatable but I can't resolve setting the ClientIDRowSuffix value. Below is a code snippet:

1. First i am populating a datatable with two columns of type text. The second column is a hyperlink (but i am not specifying that datacolumn type as hyperlink).
2. After populating the rows, i am adding the datatable to dataset.
3. then binding this dataset to the gridview (the gridview's AutoGenerateColumns=true).
Question:
Obviously, the hyperlink column is represented as text in the gridview (non-clickable hyperlink).
here i am trying to convert this hyperlink column (data rows), from text to a hyperlink, so that the user can click directly and navigate to that url.
FYI, I cannot change this method of binding, and just want to convert this text hyperlink to a real hyperlink.
