从C＃中的多个表ASP.NET中向GridView添加数据

Question

我需要知道如何将网格视图与2个表绑定，我已经将其与PostVoucher表绑定，但是我需要从事务表中添加列trans_name，该怎么办？

HTML代码：

                <asp:Label ID="debit" runat="server" Text='<%# (Eval("stat_flag").ToString() =="d" ) ? Eval("stat_amount"): "0" %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>

              <asp:TemplateField HeaderText="دائن">
            <ItemTemplate>
                <asp:Label ID="credit" runat="server" Text='<%# (Eval("stat_flag").ToString() =="c" ) ? Eval("stat_amount"): "0" %>'></asp:Label>
            </ItemTemplate>
        </asp:TemplateField>
                                <asp:BoundField  DataField="stat_desc" 
                                HeaderText="البيان" ItemStyle-Font-Size="Small"/>

                            <asp:BoundField  DataField="serial" 
                             HeaderText=" رقم السند " ItemStyle-Font-Size="Small"/>

                              <asp:BoundField  DataField="stat_date" dataformatstring="{0:dd/MM/yyyy}"
                                HeaderText="التاريخ" ItemStyle-Font-Size="Small"/>

C＃代码：

   SqlParameter[] para = new SqlParameter[4];
   para[0] = new SqlParameter("@stat_sub_leger", ddlACCcode.SelectedValue);
    para[1] = new SqlParameter("@branch", DDLBranch.SelectedValue);
    para[2] = new SqlParameter("@from", db.getDate(txtFrom.Text));
    para[3] = new SqlParameter("@to", db.getDate(txtTo.Text));

    DataTable dtreport = db.SelectCmdText("Select * from PostedVoucher where stat_sub_leger = @stat_sub_leger 
             and branch=@branch and stat_date between @from and @to ORDER BY stat_date ", para);


    GridView1.DataSource = dtreport;
    GridView1.DataBind();

@FEBY您可以编写查询以从两个表中获取组合值，然后将其绑定到您的网格
