我创建了包含 Web 部件区域和客户 Web 部件的自定义布局。
<WebPartPages:WebPartZone id="NvRDDevliverable2" runat="server" title="Zone 2">
<ZoneTemplate>
<DeliverableMapping:DeliverableMapping runat="server"
ID="DevliverableOwnership" Description="Ownership and Timing"
Title="Ownership and Timing " __MarkupType="vsattributemarkup"
__WebPartId="{804C2865-8F61-4828-8460-312ABB3DFA9A}" WebPart="true"
__designer:IsClosed="false" partorder="2"></DeliverableMapping:DeliverableMapping>
</ZoneTemplate>
</WebPartPages:WebPartZone>
当我尝试更新布局时,所有页面实例上都会出现重复的 Web 部件。如何避免这个问题?
