【问题描述】：

我有一个列出所有工作的页面。我必须编写一个按钮，以便当我单击它时，它会将我引导至特定的工作详细信息。我怎样才能做到这一点。我已经尝试过 navigateUrl，但是当我点击按钮时，什么也没有发生。

这是我的项目模板代码

<asp:ListView ID="lsvJob" runat="server">
        <ItemTemplate>
            <div class="nf-item branding coffee spacing">
                <div class="col-md-6 col-lg-4 mb-30">
                    <div class="service_box">
                        <figure>
                            <asp:Image ID="imgposter" ImageUrl='<%# Eval("HO_Image", "~/Images/0") %>'
                                runat="server" Height="300px" Width="300px" ImageAlign="Top" />
                        </figure>
                        <h3><%#Eval("Job_Name") %></h3>
                        <p>
                            <b>Employer Name:</b> <%# Eval("HO_LastName") %> <%# Eval("HO_FirstName") %>
                            <br />
                            <b>Email Address:</b> <%# Eval("HO_Email") %>
                        </p>
                        <asp:LinkButton ID="lnkmovdetails" runat="server" Text="View Details"
                            NavigateUrl='<%# Eval("Job_ID","~/jobdetails.aspx?id=0")%>' CommandName="btnAccess" CssClass="btn btn-info"></asp:LinkButton>
                    </div>
                </div>
            </div>
        </ItemTemplate>
    </asp:ListView>

    public partial class listjob : System.Web.UI.Page
    
        private string _conString =
WebConfigurationManager.ConnectionStrings["MaidCS"].ConnectionString;
        protected void Page_Load(object sender, EventArgs e)
        
            // Create Connection
            using (SqlConnection con = new SqlConnection(_conString))
            
                // Create Command
                SqlCommand cmd = new SqlCommand();
                cmd.Connection = con;
                cmd.CommandType = CommandType.Text;
                cmd.CommandText = " SELECT tblHO.*, tblJob.* FROM tblHO, tblJob WHERE tblJob.HO_ID=tblHO.HO_ID";
                //Create DataReader
                SqlDataReader reader;
                con.Open();
                reader = cmd.ExecuteReader();
                //Bind the reader to the repeater control
                lsvJob.DataSource = reader;
                lsvJob.DataBind();
                con.Close();
            
        
    

我的 jobdetail 网络表单中的代码

<asp:DetailsView ID="dsvJob" runat="server"  AutoGenerateRows="False" DataSourceID="SqlDataSource1" BackColor="White" BorderColor="#999999" BorderStyle="None" BorderWidth="1px" CellPadding="10" GridLines="Vertical">
        <AlternatingRowStyle BackColor="Gainsboro" />
        <EditRowStyle BackColor="#008A8C" Font-Bold="True" ForeColor="White" />
        <Fields>
            <asp:BoundField DataField="Job_Name" HeaderText="Job_Name" SortExpression="Job_Name" />
            <asp:BoundField DataField="Job_Desc" HeaderText="Job_Desc" SortExpression="Job_Desc" />
            <asp:BoundField DataField="Job_Salary" HeaderText="Job_Salary" SortExpression="Job_Salary" ItemStyle-HorizontalAlign="Left" />
            <asp:BoundField DataField="Deadline_Date" HeaderText="Deadline_Date" SortExpression="Deadline_Date" />
            <asp:BoundField DataField="Type" HeaderText="Type" SortExpression="Type" />
            <asp:BoundField DataField="Min_Experience" HeaderText="Min_Experience" SortExpression="Min_Experience" />
            <asp:BoundField DataField="Min_Qualification" HeaderText="Min_Qualification" SortExpression="Min_Qualification" />
        </Fields>

        <FooterStyle BackColor="#CCCCCC" ForeColor="Black" />
        <HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
        <PagerStyle BackColor="#999999" ForeColor="Black" HorizontalAlign="Center" />
        <RowStyle BackColor="#EEEEEE" ForeColor="Black"  />

    </asp:DetailsView>
    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:MaidCS %>" SelectCommand="SELECT [Job_Name], [Job_Desc], [Job_Salary], [Deadline_Date], [Type], [Min_Experience], [Min_Qualification] FROM [tblJob]"></asp:SqlDataSource>

【参考方案1】：

从 LinkBut​​ton 和以下一个中删除 navigateUrl 属性。

PostBackUrl="imagepage.aspx?v=<%#Eval("id") %>"

从查询字符串你会得到jobID。读取 JobId 并显示记录。

谢谢，希望对你有帮助:)

【参考方案2】：

命令名称不能这样工作。使用以下代码进行重定向

<asp:LinkButton ID="lnkmovdetails" runat="server" Text="View Details" PostBackUrl='~/jobdetails.aspx?id=<%#Eval("Job_ID") %>' CssClass="btn btn-info" />
