Question

你好我在mvc中创建一个webgrid来显示数据库中的数据。在数据库中有一列包含图像的路径。例如：的〜/ Images1 / PLCDTV1 / ILCDTV1.png

这是控制器的代码：

 public ActionResult Index()
        {
            SqlCommand cmd = new SqlCommand("select * from example_tbl", 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()
                });
            }
            dr.Close();
            return View(model);
        }

在上面的代码中， Ad_image_path 是包含图片路径的列。

这是我的View代码：

@model IEnumerable<Example.Models.AddDetailModel>
@{
    ViewBag.Title = "Index";
    Layout = null;
}
@{
    var grid = new WebGrid(source: Model,
                                              defaultSort: "First Name",
                                              rowsPerPage: 5, fieldNamePrefix: "wg_",
                                              canPage: true, canSort: true,
                                              pageFieldName: "pg", sortFieldName: "srt"
                                              );  
}

                                    @grid.GetHtml(tableStyle: "listing-border", headerStyle: "gridhead", footerStyle: "paging", rowStyle: "td-dark", alternatingRowStyle: "td-light",
                            columns:
                                grid.Columns(

                                grid.Column("AdName", "Ad Name", style: "colProductid"),
                                grid.Column("PartnerName", "Partner Name", style: "colProductRate"),
                                grid.Column(header: "Ad", format: @<text><img src="http://localhost:31502/Images/Landing/Lighthouse.jpg" id="adimg"  alt="YourText" title="YourText"  width:"50px" height="50px"></text>),
                                grid.Column("hrefurl", "URL", style: "colDiscountRate"),
                                grid.Column("startDate", "Start Date", style: "colCategoryID"),

                                grid.Column(header: "Delete", format: @<text><a href="@Url.Action("Delete", "Product", new { pid = item.Productid })" onclick="javascript:return ConfirmDelete();"><img
                                        src="../../Images/delete.png" width="20px" height="20px" alt="" style="border: none;" /></a></text>, style: "colOperation")
                                ), mode: WebGridPagerModes.All)
                                </td>
                            </tr>
                        </table>
                 </div>
            </td>
        </tr>
    </table>
}
</body>
</html>

正如你在webgrid的第三列中看到的那样，我保留了一个图像。它是一个硬编码值。 我希望图片的src是存储在AdPath中的值。

有什么办法可以实现吗？感谢

Answer 1

您可以通过item参数访问当前列的数据项：

grid.Column(header: "Ad", format: @<text><img src="@item.AdPath" id="adimg"  alt="YourText" title="YourText"  width:"50px" height="50px"></text>),

Answer 2

  grid.Column(format: @<img src="@Url.Content(item.Image)"  

 alt="@item.Name" height="30" width="30" />   , header: "Photo"),

试试这个.... 101％它会起作用。
