有没有办法根据它的一些子元素来订购堆栈面板?
在后面的代码中,我向堆栈面板添加了一些通用的东西,例如 groupbox 和 textblock,其中一个文本块信息是来自我的 web 服务的 DateTime,我尝试使用 linq 通过降序排序,但输出仍然相同。
所以我想知道是否可以按堆栈面板子元素之一进行排序,即包含 DateTime 属性的 textblock1.Text ?
XDocument xDoc = XDocument.Load(uriGroups);
var sortedXdoc = xDoc.Descendants("Student")
.OrderByDescending(x => Convert.ToDateTime(x.Element("TimeAdded").Value));
foreach (var node in xDoc.Descendants("Student"))
{
GroupBox groupbox = new GroupBox();
groupbox.Header = String.Format(node.Element("StudentID").Value);
groupbox.Width = 100;
groupbox.Height = 100;
groupbox.Margin = new Thickness(1);
TextBlock textBlock = new TextBlock();
textBlock.Text = String.Format(node.Element("FirstName").Value + " " + (node.Element("LastName").Value));
textBlock.TextAlignment = TextAlignment.Center;
TextBlock textBlock1 = new TextBlock();
textBlock1.Text = (DateTime.Parse(node.Element("TimeAdded").Value)).ToString("d");
String.Format("{0:d/M/yyyy}", DateTime.Parse(node.Element("TimeAdded").Value));
textBlock1.TextAlignment = TextAlignment.Center;
textBlock1.VerticalAlignment = VerticalAlignment.Bottom;
StackPanel stackPanel = new StackPanel();
stackPanel.Children.Add(groupbox);
stackPanel.Children.Add(textBlock);
stackPanel.Children.Add(textBlock1);
stackPanel.Margin = new Thickness(5);
stackPanel.MouseEnter += new MouseEventHandler(stackpanel_MouseEnter);
stackPanel.MouseLeave += new MouseEventHandler(stackpanel_MouseLeave);
MainArea1.Children.Add(stackPanel);
}
}
