Question

在$('input').each(function() { $(this).toggleClass('error', this.value == ""); }); PivotItem pivotItem = new PivotItem();之后我得到Additional information: The application called an interface that was marshalled for a different thread. (Exception from HRESULT: 0x8001010E (RPC_E_WRONG_THREAD))。它应该是什么？我很困惑。

代码：

foreach (Source source in sources)
{
    PivotItem pivotItem = new PivotItem(); /* At this point it falls. */
    pivotItem.Header = source.Name;
    pivotItem.Margin = new Thickness(0, -10, 0, 0);

    ListView listView = new ListView();
    listView.ItemsSource = source.Articles;
    listView.ItemTemplate = (DataTemplate)Resources["MainItemTemplate"];
    listView.ItemClick += OpenArticle_ItemClick;
    listView.SelectionMode = ListViewSelectionMode.None;
    listView.IsItemClickEnabled = true;

    pivotItem.Content = listView;
    pvtMain.Items.Add(pivotItem);
}

基于异常，您似乎尝试在UI线程以外的线程中创建新的<asp:GridView ShowHeader="false" AutoGenerateColumns="false" ID="GridView1" runat="server" GridLines="None"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Label runat="server" ID="QuestionID" Text='<%# Eval("QuestionID")%>' /> <asp:Label runat="server" ID="Question" Text='<%# Eval("Question")%>' /><br /> <asp:RadioButton GroupName="a" Text='<%# Eval("answer1")%>' runat="server" ID="answer1" /><br /> <asp:RadioButton GroupName="a" Text='<%# Eval("answer2")%>' runat="server" ID="answer2" /><br /> <asp:RadioButton GroupName="a" Text='<%# Eval("answer3")%>' runat="server" ID="answer3" /><br /> <asp:RadioButton GroupName="a" Text='<%# Eval("answer4")%>' runat="server" ID="answer4" /><hr /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> <asp:Button ID="btnSubmit" runat="server" Text="Submit" /> <asp:Label ID="lblOutput" runat="server" Text="" />。您只能与UI线程中的UI元素进行交互。

您可能正在从未从UI事件触发的事件处理程序中调用此代码。您应该能够使用Dispatcher切换回UI线程来解决问题：
