c# - GridView 行包含超链接，单击它后应在另一个页面中显示该特定行的值

Question

我有一个 GridView ，其中一列中包含超链接(称为 View 详细信息)，单击该超链接后，该 GridView 的特定行的详细信息应显示在另一个页面(reports.aspx)的标签中。

请帮帮我。到目前为止我已经尝试过了。

这是我的 GridView

                           <Columns>

                 </ItemTemplate>
                      <FooterStyle BackColor="#0061C1" />
                    <HeaderStyle BackColor="#0061C1" ForeColor="White" />
                     <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                          </asp:TemplateField>
                       <asp:TemplateField HeaderText="View Details">

                            <FooterStyle BackColor="#0061C1" />
                       <HeaderStyle BackColor="#0061C1" ForeColor="White" />
                        <ItemStyle HorizontalAlign="Center" VerticalAlign="Middle" />
                      </asp:TemplateField>
                              </Columns>
                         </asp:GridView>

这是我在行数据绑定(bind)上的 GridView 背后的代码

       if (e.Row.RowType == DataControlRowType.DataRow)
           {
            HyperLink ViewDetails = e.Row.FindControl("ViewDetails") as HyperLink;
            ViewDetails.NavigateUrl = "Reports.aspx?TaskID=" + e.Row.Cells[0].Text;
           }

这是我的代码或reports.aspx，其中应显示 GridView 的详细信息

       protected void Page_Load(object sender, EventArgs e)
         {
             MTMSService obj = new MTMSService();
             DBAccess db = new DBAccess();
           {
                MTMSDTO objc = new MTMSDTO();
              {
                objc.TaskID = Convert.ToInt32(Session["TaskID"]);
                DataSet rep = obj.GetReports(objc);
                DataView Rprts = new DataView();
                Rprts.Table = rep.Tables[0];


                LblTaskName.Visible = true;
                LblAssignBy.Visible = true;
                LblDescription.Visible = true;
                LblDueDate.Visible = true;
                LblStatus.Visible = true;
                LblPercentageComplete.Visible = true;
                LblAssignTo.Visible = false;
            }
        }
    }

存储过程

              ALTER PROCEDURE [dbo].[GetReports]

              @TaskID int

              AS

             Select TaskName, DueDate, Description, AssignBy, Status, PercentageComplete

             From dbo.Task

             Where TaskID = @TaskID;

Answer 1

替换这个

objc.TaskID = Convert.ToInt32(Session["TaskID"]); 

与

objc.TaskID = Convert.ToInt32(Request.QueryString["TaskID"].tostring());
