我正在尝试在将值绑定(bind)到按钮的转发器内传递值，并将它们从该表单传递到另一个表单。当我编译它时，它给我一个错误，指示
System.FormatException:输入字符串的格式不正确。
form1.aspx 中中继器代码中的按钮:
<asp:Button ID="Button1" runat="server" Text="" CommandName= "TEST" CommandArgument = '<%# Eval("Parking_ID") + "," + Eval("Parking_Name") %>' />
在form1.aspx.vb中Repeater_ItemCommand功能:
Protected Sub repeater1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles repeater1.ItemCommand
If (e.CommandName = "TEST") Then
Dim commandArgsAccept As String() = e.CommandArgument.ToString().Split(New Char() {","c})
Dim value As Int32 = commandArgsAccept(0).ToString
Dim value1 As String = commandArgsAccept(1).ToString
Response.Redirect("Default2.aspx?Parking_ID=" & value, True)
Response.Redirect("Default2.aspx?Parking_Name=" & value1, True)
Session("field4") = value
Session("field6") = value1
End If
End Sub
这个问题有什么解决办法吗？ 问候。
最佳答案
<asp:Button ID="Button1" runat="server" Text="" CommandName= "TEST" CommandArgument = '<%# Eval("Parking_ID").ToString() +","+ Eval("Parking_Name").ToString() %>'/>
Protected Sub repeater1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles repeater1.ItemCommand
If (e.CommandName = "TEST") Then
Dim commandArgsAccept As String() = e.CommandArgument.ToString().Split(",")
Dim value As Int32 = commandArgsAccept(0).ToString
Dim value1 As String = commandArgsAccept(1).ToString
Session("field4") = value
Session("field6") = value1
Response.Redirect("Default2.aspx?Parking_ID=" & value & "&Parking_Name=" & value1, True)
End If
