I am having a problem implementing a HyperLink in a ASP.NET DataGrid where there are not one but two URL Fields that I need. Rather than this:

URL field: CompanyID
URL format string: CompanyData.aspx?CompanyID={0)

I need something like:

URL field: CompanyID, IndexTypeID
URL format string: CompanyData.aspx?CompanyID={0)&IndexTypeID={1}

Any ideas?
