I have a Hyperlink column on a WebControls.DataGrid. The column is displaying a natural key. I want the hyperlink to launch another page, passing the foreign surrogate key that corresponds to the displayed natural key as a parameter. This value exists in another column in the DataSet to which the grid control is bound, but naturally isn't displayed in the grid.

What I have specified now for the URL Format String is:

PCCInfo.aspx?PCC_fk={0}

Which does a nice job of passing the displayed value to the new page, but not what I'm looking for.

Can this be done or will I need to handle it on the server side, resolving the natural key into its corresponding surrogate key or something?

On a related question, is it possible to pass mulitiple arguments to the page being called, e.g. values from different columns of the DataGrid?

Thanks.
