i have a gridview in which when i click the select command button what should happen is it should allow me to fetch a column value to be added in my sql query to fill another gridview

select distinct a.*,  from ranu.desgmaster a, tt.employees b where ( 'T')   and a.desgid = b.desgid and a.MinLeavApp <= 1 and a.MaxLeavApp >= 1 order by Designation <pre lang="sql">and desiglevel < (select DesigLevel from ranu.desgmaster where b.empdesignation =''

here the b.empdesignation will come from the upper gridview

Just add DataKeyNames="Reference" to your first GridView,

Then in the linked SqlDataSource of the second GridView, get the selected value

    <asp:ControlParameter ControlID="GridView1" Name="Reference"
        PropertyName="SelectedValue" />
