VS2008(框架3.5)上的某些東西似乎無法在VS2010(框架4)上運行。在VS2008上運行的運行時更改窗口樣式,在VS2010上無法運行
我需要在運行時更改窗口的樣式(用戶首選項)。 在VS2008此代碼的工作:
Window1.xaml
<Window x:Class="StyleTest.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow"
ResizeMode="CanResizeWithGrip">
<Window.Style>
<Style TargetType="{x:Type Window}">
<Setter Property="MinWidth" Value="400" />
<Setter Property="Width" Value="500" />
<Setter Property="MinHeight" Value="400" />
<Setter Property="SizeToContent" Value="Height" />
</Style>
</Window.Style>
<Grid>
</Grid>
</Window>
Window1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.Xml;
using System.Windows.Markup;
using System.IO;
namespace StyleTest
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
Loaded += new RoutedEventHandler(ObjDialog_Loaded);
}
void ObjDialog_Loaded(object sender, RoutedEventArgs e)
{
XmlDocumentFragment frag = new XmlDocument().CreateDocumentFragment();
frag.InnerXml = "<Style TargetType=\"{x:Type Window}\" xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\"> " +
" <Setter Property=\"Height\" Value=\"200\" />" +
" <Setter Property=\"Width\" Value=\"200\" />" +
"</Style>";
XmlNode node = frag.FirstChild as XmlElement;
Style style = LoadXaml(node.OuterXml) as Style;
if (style != null)
Style = style;
UpdateLayout();
}
private object LoadXaml(string xaml)
{
Exception ex = null;
object o = LoadXaml(xaml, out ex);
if (ex != null)
throw ex;
return o;
}
public static object LoadXaml(string xaml, out Exception exception)
{
try {
ParserContext pc = new ParserContext();
pc.XmlnsDictionary.Add("", "http://schemas.microsoft.com/winfx/2006/xaml/presentation");
pc.XmlnsDictionary.Add("x", "http://schemas.microsoft.com/winfx/2006/xaml");
pc.XmlnsDictionary.Add("l", "http://www.teradp.com/schemas/GN4/1/WinUI");
pc.XmlnsDictionary.Add("c", "clr-namespace:TeraDP.GN4.Common;assembly=Common");
exception = null;
return XamlReader.Load(new MemoryStream(Encoding.UTF8.GetBytes(xaml)), pc);
}
catch (Exception ex) {
exception = ex;
}
return null;
}
}
}
當我運行框架3.5這個代碼顯示大小爲200×200的窗口。 當我運行框架4 THW窗口這個代碼顯示大小爲500x400
最奇怪的是,如果我添加MinWidth和了minHeight在運行時應用該樣式的屬性正常工作也是在VS2010,而寬度和高度似乎被忽略。
有人有解決這個問題的辦法嗎?
設置高度和寬度不是解決方案。在我的程序中,樣式存儲爲一種「用戶選項」,並從xml文件加載。我將看看ArrangeOverride,但我真正需要的是在運行時應用樣式。 –
雖然我不確定「注入」一些XML是不錯的選擇,但您可以在runme上應用樣式... – Yahia
確定它有效,但它不是我所需要的。這個「用戶選項」(它比這更復雜,但將其視爲用戶選項)可以包含任何有效的樣式設置器,不僅包括寬度和高度。 –
