【问题描述】：
请帮助解决这个超链接的事情。我有一个网格视图，其中一列包含超链接，比如 ViewDetails。单击 ViewDetails 后，它应该导航到另一个名为 Reports.aspx 的页面，该页面应在标签的网格视图中显示所选列的网格行值。我使用了行数据绑定事件。如果我单击超链接，我会得到空白标签。我已经编写了存储过程来获取行值。我通过 KEY 调用它。它的 TaskID 是一个自动生成的不可见列。根据我需要显示行值的键值。
这里是代码
<asp:GridView ID="GrdViewMyTasks" runat="server" AllowSorting="True"
AutoGenerateColumns="False" BackColor="White" BorderColor="#0061C1"

aspx.cs 代码
protected void GrdViewMyTasks_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
HyperLink ViewDetails = e.Row.FindControl("ViewDetails") as HyperLink;
ViewDetails.NavigateUrl = "Reports.aspx?TaskID=" + e.Row.Cells[0].Text;
}
}
reports.aspx.cs 中的代码
protected void Page_Load(object sender, EventArgs e)
{
MTMSService obj = new MTMSService();
DBAccess db = new DBAccess();
{
MTMSDTO objc = new MTMSDTO();
{
//objc.TaskID = Convert.ToInt32(Request.QueryString["TaskID"]);//
DataSet rep = obj.GetReports();
DataView Rprts = new DataView();
Rprts.Table = rep.Tables[0];
var table = rep.Tables[0];
if (table.Rows.Count > 0)
{
LblTaskID.Text = rep.Tables[0].Rows[0]["TaskID"].ToString();
LblTaskName.Text = rep.Tables[0].Rows[0]["TaskName"].ToString();
LblDueDate.Text = rep.Tables[0].Rows[0]["DueDate"].ToString();
LblDescription.Text = rep.Tables[0].Rows[0]["Description"].ToString();
LblAssignBy.Text = rep.Tables[0].Rows[0]["AssignBy"].ToString();
LblStatus.Text = rep.Tables[0].Rows[0]["Status"].ToString();
LblPercentageComplete.Text = rep.Tables[0].Rows[0]["PercentageComplete"].ToString();
}
else
{
}
LblTaskName.Visible = true;
LblAssignBy.Visible = true;
LblDescription.Visible = true;
LblDueDate.Visible = true;
LblStatus.Visible = true;
LblPercentageComplete.Visible = true;
LblAssignTo.Visible = false;
}
}
}
这是我的存储过程
ALTER PROCEDURE [dbo].[GetReports]
@TaskID int
AS
Select TaskName, DueDate, Description, AssignBy, Status, PercentageComplete, TaskID
From dbo.Task
Where TaskID = @TaskID;
请让我知道我哪里出错了。从过去的 1 周开始，我无法得到完美的解决方案……这让我很头疼……
reports.cs 文件的注释行出现错误“输入字符串格式不正确”
【问题讨论】：
-
确保在导航到 Url 时，Url 在查询字符串中具有值。如果没有，那么调试“e.Row.Cells[0].Text”这是否给你正确的 ID。
-
是的 .. 它给出了正确的 ID
