为什么我的转发器控件中的图像没有显示出来 [英] Why my image in a repeater control is not getting displayed

问题描述

我使用了转发器控件来查看文件夹中的所有图像。但图像没有显示出来。请帮帮我。



这是我的代码..

I have used a repeater control to view all images from a folder. but images are not getting displayed. can u help me please.

This is my code..

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
   {
       XmlDocument xmldoc = new XmlDocument();
       xmldoc.Load(Server.MapPath("~/" + "XML/album.xml"));
       XmlNodeList nodelist = xmldoc.GetElementsByTagName("Album");
       DataTable dt = (DataTable)Session["dt"];
       if (dt.Rows.Count > 0)
       {
           for (int i = 0; i < nodelist.Count; i++)
           {
               string val = e.CommandArgument.ToString();

               string attr = nodelist[i].Attributes["Name"].Value;
               if (attr == val)
               {
                   List<string> images = new List<string>();
                   DirectoryInfo di = new DirectoryInfo(Server.MapPath("") + "\\" + val + "\\" + "Images\\");
                   int count = di.GetFiles().Length;
                   //all Images in folder add in datarow and bind to repeater control
                   DataTable imgdt = new DataTable();
                   for (int j = 0; j < count; j++)
                   {
                      string imgpath=nodelist[i].InnerText;

                       DirectoryInfo directoryInfo = new DirectoryInfo(imgpath);
                       FileInfo[] fileInfo = directoryInfo.GetFiles();

                       images.Add(fileInfo[j].Name);
                   }

                   Repeater2.DataSource = images; // i am getting image name here
                   Repeater2.DataBind();
               }
           }
       }
   }

这个设计视图。

this the desgin view.

<asp:Repeater ID="Repeater2" runat="server" onitemcommand="Repeater1_ItemCommand">
                        <ItemTemplate>
                            <td>
                                <asp:Image ID="Image1" runat="server" ImageUrl="<%# Container.DataItem %>"/>
                            </td>
                        </ItemTemplate>
                    </asp:Repeater>

推荐答案

你看到什么转发器呈现？每行HTML中呈现的路径是什么？该路径是否适合图像？我猜它不是。请告诉我。

Hi,

What do you see when the repeater is rendered? What path is being rendered in the HTML for each row? Is that path correct for an image? I am guessing it isn't. Please let me know.

protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
    {
        XmlDocument xmldoc = new XmlDocument();
        xmldoc.Load(Server.MapPath("~/" + "XML/album.xml"));
        XmlNodeList nodelist = xmldoc.GetElementsByTagName("Album");
        DataTable dt = (DataTable)Session["dt"];
        if (dt.Rows.Count > 0)
        {
            for (int i = 0; i < nodelist.Count; i++)
            {
                string val = e.CommandArgument.ToString();
                string attr = nodelist[i].Attributes["Name"].Value;
                if (attr == val)
                {
                    List<string> images = new List<string>();
                    DirectoryInfo di = new DirectoryInfo(Server.MapPath("") + "\\Gallary\\" + val + "\\" + "Images\\");
                    int count = di.GetFiles().Length;
                    //all Images in folder add in datarow and bind to repeater control
                    DataTable imgdt = new DataTable();
                    imgdt.Columns.Add("ImagesFolder", typeof(string));
                    for (int j = 0; j < count; j++)
                    {

                        DataRow dr = imgdt.NewRow();
                        string imgpath = nodelist[i].InnerText;
                        //bind folder images to datarow here.
                        dr["ImagesFolder"] = nodelist[i].InnerText;
                        imgdt.Rows.Add(dr);
                        DirectoryInfo directoryInfo = new DirectoryInfo(imgpath);
                        FileInfo[] fileInfo = directoryInfo.GetFiles();
                        string fullpath = "~\\Gallary\\" + val + "\\" + "Images\\" + fileInfo[j].Name;
                        images.Add(fullpath);                       
                    }
                     Repeater2.DataSource = images;
                     Repeater2.DataBind();
                }
            }
        }
    }</string></string>
