Gridview模板字段数据源

Question

我在我的asp.net页面上放置了一个gridview,并使用sql调用来获取数据源.在sql调用中,它带来了所有字段(名称,地址,电话,类型)的数据在gridview上,在编辑期间,有2个字段(电话,类型)需要是模板字段而不是绑定字段,并且项目模板中的文本框或标签(以较小者为准).

当我运行代码时,数据网格完成并填写 - 减去手机或类型字段(模板字段)的信息.如何对字段进行数据绑定,以便正确显示信息.我已经包含了我的代码.

任何帮助将不胜感激.提前致谢!

网格视图:

  <asp:GridView ID="gvMTM" runat="server" AllowPaging="True" DataKeyNames="MTMID"

            <ItemTemplate>
                <asp:TextBox ID="txtPhoneRead" runat="server" BorderStyle="None"></asp:TextBox>

        </asp:TemplateField>
        <asp:TemplateField HeaderText="RR">

            </ItemTemplate>
        </asp:TemplateField>
    </Columns>
</asp:GridView>

在.CS页面:

     gvMTM.DataSource = code.GetMTMList();
            gvMTM.DataBind();

SQL调用

    public DataTable GetMTMList()
    {
        try
        {
            SQLCON = new SqlConnection(connectionString);
            SQLCON.Open();
            SQLCmd = new SqlCommand("spGetMTMList", SQLCON);
            SQLCmd.CommandType = CommandType.StoredProcedure;

            SqlDataAdapter adapter = new SqlDataAdapter(SQLCmd);
            DataTable Detailtable = new DataTable();
            adapter.Fill(Detailtable);

            return Detailtable;

        }
        catch (Exception ex)
        {
            HttpContext.Current.Response.Redirect("~/ErrorRedirect.aspx?" +    ex.Message, false);
            return null;
        }
        finally
        {
            SQLCON.Close();
        }
    }

Answer 1

用这个:

Text='<%# Eval("phone") %>'

你需要添加这个:

 <ItemTemplate>
      <asp:TextBox ID="txtPhoneRead" runat="server" Text='<%# Eval("phone") %>'>
      </asp:TextBox>
 </ItemTemplate>

该Eval()方法将数据源中的数据绑定到Text属性

您可以查看他的帖子了解更多信息

注意 考虑更改to中的TextBox控件<ItemTemplate>asp:Label

它应该是这样的:

<ItemTemplate>
       <asp:Label ID="txtPhoneRead" runat="server" Text='<%# Eval("Phone") %>'>
       </asp:Label>              
 </ItemTemplate>
