我用数据库中的答案动态填充一个停靠面板,并用数据库中的问题填充另一个停靠面板。答案将被填充为标签,我尝试将标签拖放到 textblock 。是的,我可以拖放,但问题是我也想拖动标签。例如,如果Label的内容是Hello,我希望hello也被“hello”这个词拖过去,现在,当我拖动它时,它并没有拖动这个词,但是当我把它放到一个文本框,“你好”这个词被删除了。我想将动画或单词与光标一起拖动。
这是我的代码:
private void PopulateQuestion(int activityID, int taskID)
{
IList<Model.question> lstQuestion = qn.GetRecords(taskID, activityID);
StackPanel sp = new StackPanel();
StackPanel stp = new StackPanel();
foreach (Model.question qhm in lstQuestion)
{
StackPanel sp1 = new StackPanel() { Orientation = Orientation.Horizontal }; // Question
TextBlock tb = new TextBlock();
tb.Text = qhm.QuestionContent;
tb.FontWeight = FontWeights.Bold;
tb.FontSize = 24;
sp1.Children.Add(tb);
StackPanel sp2 = new StackPanel() { Orientation = Orientation.Horizontal }; // Answer
Label tb1 = new Label();
tb1.Content = qhm.Answer;
tb1.FontWeight = FontWeights.Bold;
tb1.FontSize = 24;
tb1.MouseLeftButtonDown += tb1_Click;
sp2.Children.Add(tb1);
TextBox tbox = new TextBox();
tbox.Width = 100;
tbox.FontSize = 24;
tbox.AllowDrop = true;
tbox.FontWeight = FontWeights.Bold;
if (qhm.Answer.Trim().Length > 0 )
{
sp1.Children.Add(tbox);
}
sp.Children.Add(sp1);
stp.Children.Add(sp2);
}
dockQuestion.Children.Add(sp);
dockAnswer.Children.Add(stp);
}
private void tb1_Click(object sender, RoutedEventArgs e)
{
Label lbl = (Label)sender;
DataObject dataObj = new DataObject(lbl.Content);
DragDrop.DoDragDrop(lbl, dataObj, DragDropEffects.All);
lbl.IsEnabled = false;
lbl.Foreground = (SolidColorBrush)new BrushConverter().ConvertFromString("#FFFB3B46"); // Red
}
