我有一个小型的Web应用程序.哪个工作正常,直到我在我的应用程序中添加了两个genericHandler.

我对http处理程序进行了以下更改

 <system.web>
    <authentication mode="Forms" >
        <forms protection="All" timeout="720" defaultUrl="Default.aspx" loginUrl="Login.aspx" >
        </forms>
    </authentication>
    <authorization>
        <deny users="?"/>
    </authorization>
    <compilation debug="true" targetFramework="4.0" />

    <httpHandlers>
        <!--Code Log Handler-->
        <add verb="*" path="*.aspx" type="System.Web.UI.PageHandlerFactory" />
        <add verb="*" type="InfoDomeNewUI.Handler.SendOWA" path="SendOWA.ashx" />
        <add verb="*" type="InfoDomeNewUI.Handler.SendSOS" path="SendSOS.ashx" />
    </httpHandlers>
    <customErrors mode="Off">
        <error statusCode="404" redirect="Templates/PageNotFound.html" />
    </customErrors>
</system.web>
<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <handlers>
        <!--Code Log Handler-->
        <add name="LogHandler1" path="SendOWA.ashx" verb="*" type="InfoDomeNewUI.Handler.SendOWA"/>
        <!-- SMS SENDER-->
        <add name="SendSOS" path="SendSOS.ashx" verb="*" type="InfoDomeNewUI.Handler.SendSOS"/>
    </handlers>
</system.webServer>

Could not load file or assembly 'Microsoft.Web.Infrastructure, …

我有以下示例代码,每次按下按钮时缩放:

XAML:

<Window x:Class="WpfApplication12.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525">

    <Canvas x:Name="myCanvas">

        <Canvas.LayoutTransform>
            <ScaleTransform x:Name="myScaleTransform" />
        </Canvas.LayoutTransform> 

        <Button Content="Button" 
                Name="myButton" 
                Canvas.Left="50" 
                Canvas.Top="50" 
                Click="myButton_Click" />
    </Canvas>
</Window>

*的.cs

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    private void myButton_Click(object sender, RoutedEventArgs e)
    {
        Console.WriteLine("scale {0}, location: {1}", 
            myScaleTransform.ScaleX,
            myCanvas.PointToScreen(GetMyByttonLocation()));

        myScaleTransform.ScaleX =
            myScaleTransform.ScaleY =
            myScaleTransform.ScaleX + 1;

        Console.WriteLine("scale {0}, location: {1}",
            myScaleTransform.ScaleX,
            myCanvas.PointToScreen(GetMyByttonLocation()));
    }

    private Point GetMyByttonLocation()
    {
        return new Point(
            Canvas.GetLeft(myButton),
            Canvas.GetTop(myButton));
    }
}

输出是:

scale 1, location: …

默认情况下,Validation.ErrorTemplate在WPF只是一个小红色边框没有任何ToolTip.

在Silverlight 4中,验证错误很好地开箱即用.

以下是Silverlight 4和WPF中出现的验证错误的比较

Silverlight 4

WPF

请注意WPF版本的平坦,无聊的外观与我认为的Silverlight外观相比.

WPF框架中是否存在任何类似的验证样式/模板,或者是否有人创建了很好的样式验证模板,如上面的Silverlight版本？或者我是否必须从头开始创建它们？

如果有人想尝试一下,可以使用以下代码重现上面的验证错误,适用于Silverlight和WPF

主窗口/ MainPage.xaml中

<StackPanel Orientation="Horizontal" Margin="10" VerticalAlignment="Top">
    <TextBox Text="{Binding Path=TextProperty, Mode=TwoWay, ValidatesOnExceptions=True}"/>
    <Button Content="Tab To Me..." Margin="20,0,0,0"/>
</StackPanel>

主窗口/ MainPage.xaml.cs中

public MainWindow/MainPage()
{
    InitializeComponent();
    this.DataContext = this;
}

private string _textProperty;
public string TextProperty
{
    get { return _textProperty; }
    set
    {
        if (value.Length > 5)
        {
            throw new Exception("Too many characters");
        }
        _textProperty = value;
    } …

WPF TreeView中的所选项目具有深蓝色背景和"尖锐"角.今天看起来有点过时了:

我想改变背景,看起来像在Windows 7的资源管理器中(有/无焦点):

我到目前为止所尝试的并没有删除原始的深蓝色背景,而是在它上面画了一个圆形边框,这样你就可以看到边缘和左边的深蓝色 - 丑陋.

有趣的是,当我的版本没有焦点时,它看起来很不错:

我想不要重新定义控件模板,如此处或此处所示.我想设置所需的最小属性,使所选项目在资源管理器中看起来像.

替代方案:我也很乐意将焦点选中的项目看起来像我现在所做的那样没有焦点.失去焦点时,颜色应从蓝色变为灰色.

这是我的代码:

<TreeView 
    x:Name="TreeView"
    ItemsSource="{Binding TopLevelNodes}" 
    VirtualizingStackPanel.IsVirtualizing="True"
    VirtualizingStackPanel.VirtualizationMode="Recycling">

    <TreeView.ItemContainerStyle>
        <Style TargetType="{x:Type TreeViewItem}">
            <Setter Property="IsExpanded" Value="{Binding IsExpanded, Mode=TwoWay}" />
            <Setter Property="IsSelected" Value="{Binding IsSelected, Mode=TwoWay}" />

            <Style.Triggers>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="BorderBrush" Value="#FF7DA2CE" />
                    <Setter Property="Background" Value="#FFCCE2FC" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </TreeView.ItemContainerStyle>

    <TreeView.Resources>
        <HierarchicalDataTemplate DataType="{x:Type viewmodels:ObjectBaseViewModel}" ItemsSource="{Binding Children}">
            <Border Name="ItemBorder" CornerRadius="2" Background="{Binding Background, RelativeSource={RelativeSource AncestorType=TreeViewItem}}"
                      BorderBrush="{Binding BorderBrush, RelativeSource={RelativeSource AncestorType=TreeViewItem}}" BorderThickness="1">
                <StackPanel Orientation="Horizontal" Margin="2">
                    <Image Name="icon" Source="/ExplorerTreeView/Images/folder.png"/>
                    <TextBlock Text="{Binding Name}"/> …

如何设置wpf数据网格的网格线的颜色？我可以用属性隐藏这些行GridLinesVisibility,但我不知道如何为它们着色.我尝试使用行和单元格的Borderbrush,但我没有成功.

OneWayToSource 在.NET 4.0中,绑定似乎已经破裂

我有这个简单的Xaml

<StackPanel>
    <TextBox Text="{Binding TextProperty, Mode=OneWayToSource}"/>
    <Button/>
</StackPanel>

我的代码背后看起来像这样

public MainWindow()
{
    InitializeComponent();
    this.DataContext = this;
}
private string m_textProperty;
public string TextProperty
{
    get
    {
        return "Should not be used in OneWayToSource Binding";
    }
    set
    {
        m_textProperty = value;
    }
}

在.NET 3.5中,这可以像你一样工作.将一些文本放入TextBox,按Tab键使其失去焦点,并TextProperty使用输入的任何文本进行更新TextBox

在.NET 4.0中,如果我在其中键入一些文本TextBox然后按Tab键使其失去焦点,则TextBox恢复为TextProperty(意味着"不应在OneWayToSource绑定中使用")的值.这是重读用于OneWayToSource.NET 4.0中的绑定吗？我只是想把TextBox它的价值推向TextProperty而不是相反.

更新
为此问题添加赏金,因为这已成为我项目中的市长不便,我想知道这已经改变的原因.似乎get在Binding更新源之后调用.这是OneWayToSource.NET 4.0中绑定所需的行为吗？

如是

• 它在3.5中的工作方式有什么问题？ …

我需要删除组合框周围的红色矩形.我在xaml中设置了combobox,如下所示,我试图覆盖Validation.ErrorTemplate.

        <ComboBox x:Name="comboPodkategoria" 
                            Margin="0,3,0,0"
                            IsSynchronizedWithCurrentItem="False" 
                            IsEditable="False"
                            ItemsSource="{Binding Source={StaticResource PodKategoriaLookup}, UpdateSourceTrigger=PropertyChanged, ValidatesOnDataErrors=True}"
                            SelectedValue="{Binding IDPodKategoria}"
                            DisplayMemberPath="kat_popis" SelectedValuePath="IDPodkat" TabIndex="5" Style="{StaticResource combostyle}">
                            <Validation.ErrorTemplate>
                                <ControlTemplate>
                                </ControlTemplate>
                            </Validation.ErrorTemplate> 
            </ComboBox>

用于删除红色矩形的样式,但在xaml中有一些错误,表示Visibility属性无法识别或无法访问.样式定义如下.

<Style x:Key="combostyle">
<Style.Triggers>
    <Trigger Property="Validation.HasError" Value="True">
        <Setter Property="Visibility" TargetName="NotValid" Value="Visible"/>
    </Trigger>  
</Style.Triggers>   

任何的想法？:(

我目前正在尝试实现Metro风格的窗口.
所以我在ResourceDictionary中创建了以下样式:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

<!-- Brushes -->
<SolidColorBrush x:Key="BackgroundColor" Color="#FFFFFFFF" />

<!-- Buttons -->
<Style x:Key="MetroControlBoxButton" TargetType="Button">
    <Setter Property="Background" Value="{StaticResource BackgroundColor}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Button">
                <ContentPresenter />
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

<!-- Windows -->
<Style x:Key="MetroWindow" TargetType="Window">
    <Setter Property="UseLayoutRounding" Value="True" />
    <Setter Property="WindowStyle" Value="None" />
    <Setter Property="ResizeMode" Value="NoResize" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Window">
                <Grid Background="{StaticResource BackgroundColor}">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="6" />
                        <RowDefinition Height="24" />
                        <RowDefinition Height="*" />
                        <RowDefinition Height="24" />
                        <RowDefinition Height="6" />
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="6" …

我有一节课:

public class AccountDetail
{
    public DetailScope Scope
    {
        get { return scope; }
        set { scope = value; }
    }

    public string Value
    {
        get { return this.value; }
        set { this.value = value; }
    }

    private DetailScope scope;
    private string value;

    public AccountDetail(DetailScope scope, string value)
    {
        this.scope = scope;
        this.value = value;
    }
}

和一个枚举:

public enum DetailScope
{
    Private, 
    Business, 
    OtherDetail
}

最后,我有一个.xaml文件:

<Window x:Class="Gui.Wpf.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Test" 
    SizeToContent="WidthAndHeight">

    <Grid>
        <ComboBox 
            Name="ScopeComboBox" 
            Width="120" 
            Height="23" 
            Margin="12" /> …

我有一个像这样定义的简单TextBlock

<StackPanel>
    <Border Width="106"
            Height="25"
            Margin="6"
            BorderBrush="Black"
            BorderThickness="1"
            HorizontalAlignment="Left">
        <TextBlock Name="myTextBlock"
                   TextTrimming="CharacterEllipsis"
                   Text="TextBlock: Displayed text"/>
    </Border>
</StackPanel>

哪个输出像这样

这会让我"TextBlock:显示文字"

string text = myTextBlock.Text;

但有没有办法获得实际显示在屏幕上的文字？
含义"TextBlock:显示......"

谢谢
