给你个简单的例子做参考: <div>    &nbsp;<asp:GridView ID="GridView1" runat="server" DataKeyNames="OrderID"
            DataSourceID="SqlDataSource1" AutoGenerateColumns="False" OnRowDataBound="GridView1_RowDataBound" OnRowCommand="GridView1_RowCommand" OnRowCreated="GridView1_RowCreated" OnPreRender="GridView1_PreRender">
            <Columns>                
                <asp:TemplateField HeaderText="CustomerID" SortExpression="CustomerID">                   
                    <ItemTemplate>
                        <asp:Label ID="Label2" runat="server" Text='<%# Bind("CustomerID") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="EmployeeID" SortExpression="EmployeeID">                                
                    <ItemTemplate>
                        <asp:GridView ID="grid1" runat="server" AutoGenerateColumns="false">
                            <Columns>
                                <asp:TemplateField>
                                     <ItemTemplate>
                                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("LastName") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>
                                <asp:TemplateField>
                                     <ItemTemplate>
                                        <asp:Label ID="Label1" runat="server" Text='<%# Bind("FirstName") %>'></asp:Label>
                                    </ItemTemplate>
                                </asp:TemplateField>                                
                            </Columns>
                        </asp:GridView>
                    </ItemTemplate>
                </asp:TemplateField>                
                 <asp:TemplateField HeaderText="CustomerID" SortExpression="EmployeeID">                   
                    <ItemTemplate>
                        <asp:Label ID="Label3" runat="server" Text='<%# Bind("EmployeeID") %>'></asp:Label>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>
        </asp:GridView>
    </div>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:northwindConnectionString1 %>"
            SelectCommand="SELECT [OrderID], [CustomerID], [EmployeeID], [OrderDate], [RequiredDate] FROM [Orders]"></asp:SqlDataSource>
protected void GridView1_PreRender(object sender, EventArgs e)
    {
        Label lb;
        GridView gv;
        foreach (GridViewRow rows in GridView1.Rows)
        {
            lb = (Label)rows.FindControl("Label3");
            string strlb = lb.Text;            SqlConnection myConn = new SqlConnection(ConnectionString);
            string strSql = " select EmployeeID,LastName,FirstName from Employees where EmployeeID= " + strlb;
            SqlDataAdapter myda = new SqlDataAdapter(strSql, myConn);
            DataSet ds = new DataSet();
            myda.Fill(ds);            gv = (GridView)rows.FindControl("grid1");
            gv.DataSource = ds;
            gv.DataBind();        }
    }
