asp:HyperLink DataBinding

Hello

Im using ASP.NET and C# and Using Visual Studio .NET 2003... Im having

some problem with databinding with hyperlink webcontrol in datalist...!

I dont know how to bind the data with the hyperlink that includes:

pagename.aspx?userid=1&threadid=2

here user id is the key field in usertable and threadid is the key

field in thread table!

When i bind data with it it just bind one value at a time i.e.

pagename.aspx?userid=1

But I want to add two values on querystring when click hyperlink...!

pagename.aspx?userid=1&threadid=2

I'll be very thankful to you for this act of kindness...
