Auto size Button Style | 易学教程

问题

I have this Style:

<!--Normal Button Style -->
<Style TargetType="{x:Type Button}" x:Key="NormalButtonStyle">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ButtonBase}">
                <Grid Background="{TemplateBinding Background}" SnapsToDevicePixels="True" Effect="{DynamicResource ShadowEffect}" >
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="16"/>
                        <ColumnDefinition/>
                    </Grid.ColumnDefinitions>

                    <Image Source="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Tag}" HorizontalAlignment="Left" Width="16" Stretch="None"  Margin="0,1" />
                    <!--<TextBlock Grid.Column="1" Text="{TemplateBinding Content}" Width="Auto" Margin="0,1" Padding="0" TextWrapping="Wrap" VerticalAlignment="Center" />-->         
                    <ContentPresenter Grid.Column="1" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" 
                      VerticalAlignment="{TemplateBinding VerticalContentAlignment}" RecognizesAccessKey="True" />
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

And this Button:

<Button Content="Record" HorizontalAlignment="Left" 
    VerticalAlignment="Top" Width="63" Style="{StaticResource NormalButtonStyle}" 
    Tag="Blabla.png" Height="24"/>

That gives me this:

The Question

For localization reasons, How to make the button with automatic size depending on the inner text?

回答1:

Your code is also working.You have to remove "Width=63" from buttton only.

Another approach Here I am using stackpanel as stack panel size based on the contents and ignores how much space is available and used TextWrapping here if there is extra space available.

 <Window.Resources>
    <Style TargetType="{x:Type Button}" x:Key="NormalButtonStyle">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type ButtonBase}">
                    <StackPanel MinHeight="{TemplateBinding MinHeight}" Orientation="Horizontal" Background="{TemplateBinding Background}" SnapsToDevicePixels="True" Effect="{DynamicResource ShadowEffect}" >
                        <Image VerticalAlignment="Center" HorizontalAlignment="Center" Source="{Binding RelativeSource={RelativeSource TemplatedParent}, Path=Tag}" Margin="2,0,2,0"  Width="16" Height="16" Stretch="None"/>
                        <TextBlock MaxWidth="{Binding Path=ActualWidth,RelativeSource={RelativeSource TemplatedParent}}"  HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Text="{TemplateBinding Content}" TextWrapping="Wrap" />
                    </StackPanel>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Window.Resources>
<Grid ShowGridLines="True" Width="500">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="100"/>            
    </Grid.RowDefinitions>
    <Button Content="R" HorizontalAlignment="Left" MinHeight="30" Padding="2,0,5,0"  Style="{StaticResource NormalButtonStyle}" Tag="btn1.jpg"/>
    <Button Content="Record" HorizontalAlignment="Left" Grid.Row="1" MinHeight="30" Padding="2,0,5,0"  Style="{StaticResource NormalButtonStyle}" Tag="btn1.jpg"/>
    <Button Content="Record here" HorizontalAlignment="Left" Grid.Row="2" MinHeight="30" Padding="2,0,5,0"  Style="{StaticResource NormalButtonStyle}" Tag="btn1.jpg"/>
    <Button Content="Record record record record Record record record record Record record record record Record record record record Record record record record Record record record record" Grid.Row="3" MinHeight="30" Padding="2,0,5,0"  Style="{StaticResource NormalButtonStyle}" Tag="btn1.jpg"/>
    <Button Content="Record record record record Record record record record Record record record record Record record record record Record record record record Record record record record" Grid.Row="4" MinHeight="30" Padding="2,0,5,0"  Style="{StaticResource NormalButtonStyle}" Tag="btn1.jpg"/>
</Grid>

Note :

Use MinHeight / MinWidth / MaxHeight / MaxWidth properties in style designing.it helps in localization.
Use Auto sizing grid for Designing.

Result

回答2:

Simple: don't give the button a fixed width (you've set it to 63) and make sure its HorizontalAlignment is not set to Stretch (so Left is fine).

You may also want to add some padding to give the text more breathing space.
