Ajax 날짜 달력을 사용하는 웹 양식이 있습니다. 이것은 잘 작동합니다. 문제는 내가 내 양식을 제출할 때 다음과 같은 메시지가 나타납니다.System.ArgumentException : 문자열 값을 날짜로 변환 할 수 없습니다.
'String value can not be converted to a date' .AgendaDate = New SmartDate(txtAgendaDate.Text)
는 여기에 내가 웹 양식에 대한 그것에 관련된 속성을 가진 클래스를 가지고있는 일정 및 관련 텍스트 상자를 보유하고 내 웹 양식 ...
<td>
<asp:TextBox ID="txtAgendaDate" runat="server" ForeColor="Black" ></asp:TextBox>
</td>
<td>
<asp:ImageButton runat="Server" ID="ImageButton1" ImageUrl="~/images/calendarpic.png"
AlternateText="Click here to display calendar" />
<cc1:calendarextender ID="CalendarExtender1" runat="server"
TargetControlID="txtAgendaDate" PopupButtonID="ImageButton1" >
</cc1:calendarextender>
</td>
입니다. 나머지 필드는 ajax 달력의 텍스트 필드를 제외하고 데이터베이스에 데이터를 전송하고 제출합니다. 여기

다음은 웹 페이지의 버튼 코드입니다. 이 속성/필드를 기반으로 오류가 발생하는 페이지입니다. 문제는
Protected Sub btnAddAgendaTemplate_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddAgendaTemplate.Click
'This works alongside the Class named Agenda_Temp which has the properties and DB connection assigned to it for each web form field.
Dim oAgenda_Temp As New Agenda_Temp
'Within the object Agenda_Temp Class use the properties defined.
'They are required to be defined in the Agenda_Temp/ app code so we can use them within here.
With oAgenda_Temp
.Organiser = txtOrganiser.Text
.Meeting = txtMeeting.Text
.AgendaDate = New SmartDate(txtAgendaDate.Text)
'Within the object Agenda_Temp class use the defined DAL which includes all the DC connect and stored procedures.
oAgenda_Temp.AgendaID = Agenda_TempDAL.AddAgenda_Temp(oAgenda_Temp)
End With
End Sub
End Class
가 나는 그것의 문자열 값을 날짜로 변환 할 수없는 것을 말해 이해 ... 버튼의
.AgendaDate = New SmartDate(txtAgendaDate.Text)
전체 코드는 여기에 ...이 라인에있다 하지만 나는 이것을 배울 줄 모른다. 내가 .net 2010에 처음 왔을 때?
도움을 주시면 감사하겠습니다. MSDN에서 :

경우 문자열을 사용합니다 SmartDate''의 생성자입니까? 많은 코드를 보여 줬는데 왜 관련 부분을 빠뜨린거야? –
