i gave general solution
Nesting GridView controls in ASP.NET were described in that
almost “canonical” Microsoft walkthrough [1]. In general,

DataSource1 (SqlDataSource, AccessDataSource, etc.) and
second "nested" GridView2 with its underlying DataSource2
residing within a TemplateField in master GridView1.
