i have written like this and it is displaying the current index value.but i want to store and display prvs ,current value in gridview3.

Within pageLoad written:
if (Session["shoppingSession"] == null)
{
ds = new DataSet();

Session["shoppingSession"] = ds;
}
else
{
ds = (DataSet)Session["shoppingSession"];
ad = new SqlDataAdapter("select *from REG where Stu_Reg= '"+ str +"', cn);
ds = new DataSet();
ad.Fill(ds, "REG");
GridView3.DataSource = ds;
GridView3.DataBind();
}

***********
Within Row_Command:

if (e.CommandName == "Show")
{
GridViewRow grv = (GridViewRow)((Button)e.CommandSource).NamingContainer;
Button btn = (Button)GridView1.Rows[grv.RowIndex].FindControl("Button1");
GridView grd2 = (GridView)GridView1.Rows[grv.RowIndex].FindControl("GridView2");

str = GridView1.Rows[grv.RowIndex].Cells[0].Text;
if (btn.Text == "Expand")
{
ad = new SqlDataAdapter("select *from REG where Stu_Reg='" + str + "'", cn);
ds = new DataSet();
ad.Fill(ds, "REG");
GridView3.DataSource = ds;
GridView3.DataBind();
}
}
