Bind that Gridview in RowDataBound Event Like Below

C#

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)// Bind nested grid view with parent grid view
        {
           // int Id =Convert.ToInt32(( (Label)e.Row.FindControl("Label3")).Text);
            GridView childgrd = (GridView)e.Row.FindControl("GridView2"); // find nested grid view from paretn grid veiw
            childgrd.DataSource = ds;
            childgrd.DataBind();
          }
    }

Hi,
Use this if ur binding data at the time of databinding

C++

protected void gv_RowDataBound(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow) {
        GridView gv = e.Row.FindControl("GridView2");
        SqlDataSource dbSrc = new SqlDataSource();
        dbSrc.ConnectionString = ConfigurationManager.ConnectionStrings("NorthwindConnectionString2").ConnectionString;
        dbSrc.SelectCommand = "SELECT * FROM Orders WHERE CustomerID = '" + e.Row.DataItem("CustomerID").ToString + "' ORDER BY OrderDate";

        gv.DataSource = dbSrc;
        gv.DataBind();
    }
}
