我如何检测链接按钮火命令按钮在网格视图控制
本文关键字：按钮 命令 网格 控制 视图 链接 何检测 检测 | 更新日期: 2023-09-27 18:01:27
我有一个奇怪的问题，那就是我已经开发了一个web应用程序的形式之一，我使用Gridview控件与命令按钮来查看行数据。如果在Gridview数据中只有记录，那么链接按钮工作正常，如果它不止一个记录不工作链接按钮，我无法理解，这对我来说是非常奇怪的问题，我有使用!IsPostBack也在页面加载事件，请帮助我.....
protected void grdmanageloans_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Info")
{
try
{
int loanid = Convert.ToInt32(e.CommandArgument);
Session["Loanid"] = loanid;
Session["Edit"] = "Edit";
TabContainer1.ActiveTabIndex = 1;
Session["TabContainer1"] ="loantab";
Session["Tabloan"] = "Tabloan";
Response.Redirect("Mortgageclient.aspx");
}
catch { }
}
if (e.CommandName == "Delete")
{
try
{
int LoanId = Convert.ToInt32(e.CommandArgument);
var PmtScheduleHistory = from del in mortgageentity.Pmt_Schedule_History where del.Loan.Loan_ID == LoanId select del;
var LoanPayment = from del in mortgageentity.Payments where del.Loan_ID == LoanId select del;
if (PmtScheduleHistory.Count() > 0)
{
var DelPmtScheduleHistory = (from del in mortgageentity.Pmt_Schedule_History where del.Loan.Loan_ID == LoanId select del).First();
mortgageentity.DeleteObject(DelPmtScheduleHistory);
mortgageentity.SaveChanges();
}
var Getpayments = from db in mortgageentity.Payments where db.Loan_ID == LoanId select db;
if (Getpayments.Count() > 0)
{
foreach (var i in Getpayments)
{
mortgageentity.DeleteObject(i);
mortgageentity.SaveChanges();
}
}
if (LoanPayment.Count() > 0)
{
var DelPmtScheduleHistory = (from del in mortgageentity.Payments where del.Loan_ID == LoanId select del.Payment_Status.PaymentStatus_ID).First();
mortgageentity.DeleteObject(DelPmtScheduleHistory);
mortgageentity.SaveChanges();
}
var deletedata = (from del in mortgageentity.Loans where del.Loan_ID == LoanId select del).First();
mortgageentity.DeleteObject(deletedata);
mortgageentity.SaveChanges();
BindData();
}
catch { }
}
if (e.CommandName == "AddNewloan")
{
Session["Addnewloan"] = "Addloan";
Response.Redirect("Information.aspx");
}
}
这是我的。aspx页面

试试这个:
<asp:LinkButton ID="lnkeinfo" runat="server" CausesValidation="false" CommandName="Info"
CommandArgument='<%# Bind("Loan_ID") %>'>Information</asp:LinkButton>
为什么不使用RESTful架构来不将这些参数保存在Session中并使页面紧密耦合呢?只需在您的网格中创建名为Info的链接，而不是按钮(该按钮返回数据)，这些参数附加到它们的末尾为querystring。这是一个更好的方法，结果是一样的。
