我对 vb.net asp.net webparts 有以下问题。我试图在 webparts 之间创建一个静态连接,但我遇到了一个问题,即:
找不到 ID 为“Ucl_Diary_Summary1”的连接提供程序 Web 部件
我将以下内容定义为我的 iterface:
Public Interface IDiaryPartsProvider
function Test as String
End Interface
我有以下作为我的消费者(用户控件):
Partial Class UsrCtrls_Diary_ucl_DiaryAwaitingReview
Inherits System.Web.UI.UserControl
<ConnectionConsumer("Test", "myID")> _
Public Sub GetTextTransferInterface(ByVal provider As IDiaryPartsProvider)
Dim a As String = provider.Test()
UserMsgBox(a.ToString, Me.Page)
End Sub
End Class
我将以下内容定义为我的提供者(用户控件):
Partial Class UsrCtrls_Diary_Diary_Summary
Inherits System.Web.UI.UserControl
Implements IWebPart, IDiaryPartsProvider
<ConnectionProvider("myID")> _
Public Function Test() As String Implements IDiaryPartsProvider.Test
Return "this is a test"
End Function
End Class
我的 default.aspx 如下:
<%@ Register Src="UsrCtrls/Diary/ucl_Diary_Summary.ascx" TagName="ucl_Diary_Summary"
TagPrefix="uc4" %>
<%@ Register Src="UsrCtrls/Diary/ucl_DiaryAwaitingReview.ascx" TagName="ucl_DiaryAwaitingReview"
TagPrefix="uc5" %>
<asp:WebPartManager ID="WebPartManager1" runat="server">
<StaticConnections>
<asp:WebPartConnection ID="cnn"
ConsumerID="Ucl_DiaryAwaitingReview1"
ProviderID="Ucl_Diary_Summary1"
/>
</StaticConnections>
</asp:WebPartManager>
<asp:WebPartZone ID="zoneDiaryTopLeft" runat="server" EmptyZoneText="Add WebPart Here" DragHighlightColor="#454777" HeaderText=" ">
<ZoneTemplate>
<asp:Panel ID="pnl1" runat="server" title="Claims Awaiting Review">
<asp:UpdatePanel ID="udp_TopLeft" runat="server" ChildrenAsTriggers="False" UpdateMode="Conditional">
<ContentTemplate>
<uc5:ucl_DiaryAwaitingReview ID="Ucl_DiaryAwaitingReview1" runat="server" title="Claims Awaiting Review" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
</ZoneTemplate>
</asp:WebPartZone>
<asp:WebPartZone ID="zoneDiaryTopRight" runat="server" EmptyZoneText="Add WebPart Here" DragHighlightColor="#454777" HeaderText=" ">
<ZoneTemplate>
<asp:Panel ID="PNL2" runat="server" title="Diary Summary">
<asp:UpdatePanel ID="udp_TopRight" runat="server" ChildrenAsTriggers="False" UpdateMode="Conditional">
<ContentTemplate>
<uc4:ucl_Diary_Summary ID="Ucl_Diary_Summary1" runat="server" Title="Diary Summary" />
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
</ZoneTemplate>
</asp:WebPartZone>
我只能假设它是因为我有我的 webparts - usercontrol 包装在一个面板中(用于滚动),还有一个我用来刷新的 updatepanel,那么我如何让它看到 usercontrol?
