[英]Set size of border inside ControlTemplate to size of button
I want a ControlTemplate for a few buttons so I can control the colour of the button when the mouse is over it.我想要几个按钮的 ControlTemplate,这样当鼠标悬停在按钮上时,我可以控制按钮的颜色。 The problem is that I use a border as the ControlTemplate content and I want the size (BorderThickness) of that border to be equal to the button's size.问题是我使用边框作为 ControlTemplate 内容,并且我希望该边框的大小(BorderThickness)等于按钮的大小。 And since the button is part of a grid, its size is flexible.由于按钮是网格的一部分,它的大小是灵活的。 This is my code so far:到目前为止,这是我的代码:
<Window x:Class="WPFTesting.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:local="clr-namespace:WPFTesting"
mc:Ignorable="d"
Title="MainWindow" Height="400" Width="350">
<Window.Resources>
<Style TargetType="Button" x:Key="ex">
<Setter Property="Background" Value="Black"/>
<Setter Property="Foreground" Value="White"/>
<Setter Property="FontSize" Value="50"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<Grid.RowDefinitions>
<RowDefinition/>
<RowDefinition/>
<RowDefinition/>
</Grid.RowDefinitions>
<Button Content="Btn0" Margin="0, 10, 0, 30" Style="{StaticResource ex}" Grid.Row="0"/>
<Button Content="Btn1" Margin="0, 10, 0, 30" Grid.Row="1"/>
<Button Content="Btn2" Margin="0, 10, 0, 30" Grid.Row="2"/>
</Grid>
How can I make the BorderThickness fill the entire grid row.
如何使 BorderThickness 填充整个网格行。
Should I even be using a border as the ControlTemplate content in the first place?
我是否应该首先使用边框作为 ControlTemplate 内容?
You should just write你应该写
<ControlTemplate TargetType="Button">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}">
<ContentPresenter
HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Border>
</ControlTemplate>
