我正在尝试创建一个UserControl,它是图形项的图例, 我已经定义了它,因此它有一个带有图形名称的标签,一个复选框 定义我们是否显示它和一个带有图形颜色的矩形。
xaml的定义如下:
<UserControl x:Class="Resources.LegendItem"
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">
<UserControl.Template>
<ControlTemplate>
<StackPanel Margin="1,0,0,0" Orientation="Horizontal">
<CheckBox Name="cb" IsChecked="{TemplateBinding IsGraphVisible}" >
<StackPanel Margin="1,0,0,0" Orientation="Horizontal">
<Rectangle Name="rec" RadiusX="2" RadiusY="2" Height="10" Width="10" />
<Label Name="lab" Content="{TemplateBinding GraphName}" />
</StackPanel>
</CheckBox>
</StackPanel>
</ControlTemplate>
</UserControl.Template>
</UserControl>
和cs文件是:
namespace Resources
{
public partial class LegendItem : UserControl
{
public static readonly DependencyProperty IsGraphVisibleProperty = DependencyProperty.Register("IsGraphVisible", typeof(Boolean), typeof(LegendItem));
public static readonly DependencyProperty GraphNameProperty = DependencyProperty.Register("GraphName", typeof(String), typeof(LegendItem));
public bool IsGraphVisible
{
get { return (bool)GetValue(IsGraphVisibleProperty); }
set { SetValue(IsGraphVisibleProperty, value); }
}
public string GraphName
{
get { return (string)GetValue(GraphNameProperty); }
set { SetValue(GraphNameProperty, value); }
}
public LegendItem()
{
InitializeComponent();
}
}
}
但是当我编译它时,我得到一个错误“无法在类型'Control'上找到静态成员'IsGraphVisibleProperty'。” 任何帮助将不胜感激。

根本不需要模板。 UserControl
允许直接声明XAML。您无法在UserControl
:
<UserControl x:Class="Resources.LegendItem" x:Name="MyControl"
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">
<StackPanel Margin="1,0,0,0" Orientation="Horizontal">
<CheckBox Name="cb" IsChecked="{Binding ElementName=MyControl, Path=IsGraphVisible}" >
<StackPanel Margin="1,0,0,0" Orientation="Horizontal">
<Rectangle Name="rec" RadiusX="2" RadiusY="2" Height="10" Width="10" />
<Label Name="lab" Content="{Binding ElementName=MyControl, Path=GraphName}" />
</StackPanel>
</CheckBox>
</StackPanel>
</UserControl>

您需要在TargetType="{x:Type Resources.LegendItem}"
上指定ControlTemplate
,否则默认为Control
的模板,您就会收到错误。
