passing query string as variable from aspx.cs to aspx

[vivekrobotics]

hi all,
this is vivek

/// Write out hyperlinks that show the descriptions and include the
ImageID in a querystring

Response.Write("<a href='Description.aspx?imageid=" + myDR["ImageID"] +
"'>" + myDR["ItemCode"]+ " " + myDR["Description"] + "&br&br&br" +
myDR["Price"] + "</a><br>");

Now I want to use this in datagrid's hyperlink column in navigateurl
property.

I don't know how to pass any variable from aspx.cs page to aspx page.

Plz help
