Question

我正在开展一个项目，我必须在其中展示一些webgrids。这些webgrids具有相同的数据源，但应根据某些条件进行划分。这是我的控制器代码：

public ActionResult Index()
        {

            SqlCommand cmd = new SqlCommand("select * from Bspecial_Ad_management_tbl where ", con);
            con.Open();
            SqlDataReader dr = cmd.ExecuteReader();
            List<AddDetailModel> model = new List<AddDetailModel>();
            while (dr.Read())
            {
                model.Add(new AddDetailModel()
                {
                    AdName = dr["Ad_name"].ToString(),
                    AdType=dr["Ad_type_name"].ToString(),
                    PartnerName=dr["Partner Name"].ToString(),
                    hrefurl=dr["Ad_url"].ToString(),
                    startDate=dr["Start_date"].ToString(),
                    endDate = dr["End_date"].ToString(),
                    tagName = dr["Tag"].ToString(),
                    AdPath= dr["Ad_image_path"].ToString(),
                    Status = dr["Status"].ToString()
                });
            }
            dr.Close();
            return View(model);
        }

这是我的观点：

@model IEnumerable<EShopPartnerSetting.Models.AddDetailModel>
@{
   {
        Layout = "~/Views/Shared/AdminLayout.cshtml";
    }

}
@{
    var grid = new WebGrid(source: Model,
                                              defaultSort: "First Name",
                                              rowsPerPage: 5, fieldNamePrefix: "wg_",
                                              canPage: true, canSort: true,
                                              pageFieldName: "pg", sortFieldName: "srt"
                                              );  
}

        @Html.ValidationSummary(true)

                        <script type="text/javascript">

                                return confirm("Are you sure you want to delete this?");
                            }
                        </script>
                    </div>
                    @* <a id="clk">click here</a>*@
                    <div id="dialog" title="Edit" style="overflow: hidden;">
                    </div>
                    <div id="newdialog" title="Create" style="overflow: hidden;">
                    </div>
                </td>
            </tr>
        </table>
    }
</body>
</html>

从控制器代码中可以看出，我有一个名为 AdType 的参数，可能只有2个值：1和2.现在我想显示两个webgrids，一个有AdType值1和其他2. 两个webgrids都具有相同的数据源。谢谢

您可以使用linq查询过滤模型：

@{
     var grid1 = new WebGrid(source: Model.Where(m=>m.AdType=="1").ToArray(),
                                          defaultSort: "First Name",
                                          rowsPerPage: 5, fieldNamePrefix: "wg_",
                                          canPage: true, canSort: true,
                                          pageFieldName: "pg", sortFieldName: "srt"
                                          );  

     var grid2 = new WebGrid(source: Model.Where(m=>m.AdType=="2").ToArray(),
                                          defaultSort: "First Name",
                                          rowsPerPage: 5, fieldNamePrefix: "wg_",
                                          canPage: true, canSort: true,
                                          pageFieldName: "pg", sortFieldName: "srt"
                                          );  
}

if else条件在mvc中显示webgrid
