在一个页面中,我设置了一个如下按钮:
<myProject:ButtonWithImage ImageSource="/Resources/test.png" Text="Back" Name="btnBack1" Command="NavigationCommands.GoToPage" CommandParameter="ViewModel/Categories.xaml" />
但是,文本和图像源不在按钮上!他们没有出现。我做错了什么?您已经命名了
UserControl
ImageControl
,但是您尝试使用nameImageButton
在XAML中访问它。如果你坚持用一个名字,你会有更多的运气。请尝试以下方法:
<UserControl x:Class="myProject.ButtonWithImage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:myProject="clr-namespace:myProject;assembly=myProject.BusinessLogic"
mc:Ignorable="d"
Name="ImagedControl"
d:DesignHeight="300" d:DesignWidth="300">
<Button Height="35" Width="90" FocusVisualStyle="{x:Null}" Foreground="White"
Click="OnClick" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Padding="0 0 1 1">
<StackPanel Orientation="Horizontal" Margin="3">
<Image Source="{Binding ElementName=ImagedControl, Path=ImageSource}" Stretch="None" Margin="0 0 5 0" />
<TextBlock Text="{Binding ElementName=ImagedControl, Path=Text}" FontSize="12" VerticalAlignment="Center" />
</StackPanel>
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" CornerRadius="8">
<Border.Background>
SlateBlue
</Border.Background>
</Border>
</ControlTemplate>
</Button.Template>
</Button>

这还假设您已在
用户控件中正确声明了两个类型正确的DependencyProperty
,分别命名为ImagesSource
和Text
,并为它们设置了适当的值。已创建按钮用户控件
<Button x:Class="WpfApplication5.UserControl1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300"
FocusVisualStyle="{x:Null}" Content="ok" Foreground="White" Height="30" Width="90" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Padding="0 0 1 1">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" CornerRadius="8">
<Border.Background>
SlateBlue
</Border.Background>
<StackPanel Orientation="Horizontal" Margin="3">
<Image Source="{Binding Path=Tag, RelativeSource={RelativeSource TemplatedParent}}" Height="30" Width="30" Stretch="Fill" Margin="0 0 0 0" />
<TextBlock Text="{Binding Path=Content,RelativeSource={RelativeSource TemplatedParent}}" FontSize="12" VerticalAlignment="Center" />

将Name=“btnBack1”更改为x:Name=“btnBack1”可能不是这样,但它是安全的,并将Name=“ImagedButton”添加到您的用户控件将Name=“btnBack1”更改为x:Name=“btnBack1”可能不是这样,但更安全。。。是什么让您认为这样做更安全?至少在VS2010、VS2012、VS2013中,在使用.Net 3.5时,您可能会遇到这样一种情况,即指定了Name属性的UserControl将导致VS在输出窗口中生成带有奇怪描述的xaml有效性问题
