Hello All，



以下是我在datalist中显示的图像代码。但是每当点击图像时，一些图像路径就会被破坏而不可见。

Hello All,

Below is my code for image to be shown in datalist. But whenever the image is clicked some images path are broken and not visible.

<asp:DataList runat="server" ID="dataimg" RepeatColumns="4" RepeatDirection="Horizontal"

                             ItemStyle-CssClass="panel" CssClass="table">
                            <ItemTemplate>
                                <li class="list-group-item list-group" style="width: 200px">
                                    <a href='<%# String.Concat("Img/",Eval("image")) %>' class="fancybox"

                                        target="_blank" title='<%#Eval("detail") %>' data-fancybox-group="testgroup">
                                        <img src='Img/<%#Eval("image") %>' alt="image" width="160px" height="160px" />
                                    </a>
                                    <asp:Label ID="Label1" runat="server" CssClass="text text-default" Font-Size="12px" Text='<%#Eval("detail") %>'></asp:Label>
                                    <%--<label id="label">
                                    <a href="<%#"design.aspx?pid="+Eval("ID") %>">View Details</a></label>--%>
                                </li>
                            </ItemTemplate>
                        </asp:DataList>

以下是我的C＃代码： -

Below is my C# code:-

 protected void Unnamed1_Click(object sender, EventArgs e)
    {
        // NB: The "as" operator can return null:
        LinkButton lnk = sender as LinkButton;
        if (lnk == null)
        {
            throw new InvalidOperationException("sender is not a LinkButton!");
        }

        DateTime theDate;
        // NB: If your date is in a specific format, use TryParseExact instead.
        string format = "yyyy-MM-dd";
        if (!DateTime.TryParseExact(lnk.Text, format, null, DateTimeStyles.None, out theDate))
        {
            // The text is not a valid date:
            throw new FormatException(string.Format("The value '{0}' is not a valid date.", lnk.Text));
        }

        TextBox1.Text = lnk.Text;

        using (SqlConnection con1 = new SqlConnection(ConfigurationManager.AppSettings["str"]))
        using (SqlCommand cmd = new SqlCommand("SELECT * FROM date1 WHERE ddate = @ddate", con1))
        {
            cmd.Parameters.AddWithValue("@ddate", theDate.Date);

            DataSet ds1 = new DataSet();
            SqlDataAdapter da1 = new SqlDataAdapter(cmd);
            da1.Fill(ds1);

            dataimg.Visible = true;
            dataimg.DataSource = ds1;
            dataimg.DataBind();
        }
    }

Please HELP!!

推荐答案

分析渲染的html 。查看分配给这些图像标记的图像URL。确保图像存在于所需的文件夹中。

Analyze the rendered html. See what are the image urls assigned to those image tags. Make sure the images exist in the required folder.
