Question

我是pivot和wp8的新手。我想从动态数据透视表项中访问某些内容的值。这是我的动态枢轴项目

for (var i = 0; i < Globals.quizcount; i++)
                {
                    var count = i + 1;
                    if (count == Globals.quizcount)
                    {

                        var stackpanel = new StackPanel();
                        var textblok = new TextBlock { Text = o["questions"][i]["question"].ToString(), FontSize = 20, Width = 450 };
                        textblok.TextWrapping = TextWrapping.Wrap;
                        stackpanel.Children.Add(textblok);
                        var radio = new RadioButton { Content = "Yes", GroupName = "userans", Name = "ansYes" + count };
                        stackpanel.Children.Add(radio);
                        var radio1 = new RadioButton { Content = "No", GroupName = "userans", Name = "ansNo" + count };
                        stackpanel.Children.Add(radio1);
                        var button = new Button { Content = "Submit", Name = "submitQuiz" };
                        button.Click += new RoutedEventHandler(getAnswer); 
                        stackpanel.Children.Add(button);
                        quizPivot.Items.Add(new PivotItem { Name = "question" + count, Header = "Question " + count, Content = stackpanel });
                        //quesId.Text = o["questions"][i]["_id"].ToString();Click="Button_Click"

                    }
                    else
                    {
                        var stackpanel = new StackPanel();
                        var textblok = new TextBlock { Text = o["questions"][i]["question"].ToString(), FontSize = 20, Width = 450 };
                        textblok.TextWrapping = TextWrapping.Wrap;
                        stackpanel.Children.Add(textblok);
                        var radio = new RadioButton { Content = "Yes", GroupName = "userans", Name = "useransYes" + count };
                        stackpanel.Children.Add(radio);
                        var radio1 = new RadioButton { Content = "No", GroupName = "userans", Name = "useransNo" + count };
                        stackpanel.Children.Add(radio1);
                        //, HorizontalAlignment = "Left", Margin = "66,317,0,0", VerticalAlignment = "Top
                        quizPivot.Items.Add(new PivotItem { Name = "question" + count, Header = "Question " + count, Content = stackpanel });
                       // quesId.Text = o["questions"][i]["_id"].ToString();
                    }
                }

我不知道如何获取文本块的值并检查选中了哪个单选按钮。需要帮助

谢谢

您可以尝试以这种方式访问动态创建的TextBlock和RadioButton：

//get stackpanel from the first pivot item
var pivotItem = (PivotItem)quizPivot.Items[0];
var stackpanel = (StackPanel)pivotItem.Content;
foreach(var control in stackpanel.Children)
{
    if(control is RadioButton)
    {
        var radio = (RadioButton)control;
        //do something with RadioButton
    }
    else if(control is TextBlock)
    {
        var textblok = (TextBlock)control;
        //do something with TextBlock
    }
}

上面的示例演示了如何从第一个透视项（quizPivot.Items[0]）获取控件。这基本上与您从C＃代码创建控件时所做的相反。
