WPF UI 设计需要自动适应窗体大小,那么Grid是非常好的布局控件。

首先看看这个控件的布局：

这个Grid是3列5行的布局, Grid里面可以包含任何子元素,因此是所有布局的首选, 还有一些其他的空间如DockPanel,Canvas,StackPanel,WarpPanel也是非常好的布局控件.

先看如下代码：

        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        
        <Grid.RowDefinitions>
            <RowDefinition Height="25"/>
            <RowDefinition Height="60"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="25"/>
            <RowDefinition Height="20"/>
        </Grid.RowDefinitions>

 不多说,上UI全部的代码：

    <Grid Background="#989898">
        
        <Grid.ColumnDefinitions>
            <ColumnDefinition/>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        
        <Grid.RowDefinitions>
            <RowDefinition Height="25"/>
            <RowDefinition Height="60"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="25"/>
            <RowDefinition Height="20"/>
        </Grid.RowDefinitions>
        
        <Border Background="#989898" BorderBrush="#989898" BorderThickness="2,0,2,2"  Margin="0,0,5.643,0"  Height="24.75" VerticalAlignment="Top" Grid.ColumnSpan="3" HorizontalAlignment="Right" Width="112">
            <WrapPanel>
                <Button Height="22.75" Name="btn_Top"  Width="35" Content="T" Margin="0,0,1,0" HorizontalAlignment="Stretch" VerticalAlignment="Top"/>
                <Button Height="22.75" Name="btn_Min" Width="35" Content="-"  Margin="0,0,1,0" HorizontalAlignment="Stretch" VerticalAlignment="Top"/>
                <Button Height="22.75" Name="btn_Close" Width="35" Content="X"  Margin="0,0,1,0" HorizontalAlignment="Stretch" VerticalAlignment="Top"/>
            </WrapPanel>
        </Border>
        
        <DockPanel Grid.Row="1" Grid.ColumnSpan="3" Margin="7,0" Background="#989898">
            <Label Height="28" Name="lblForder" Margin="7,0,0,0">Forder Path：</Label>
            <Button Height="23" Name="btn_Broswer" DockPanel.Dock="Right" Padding="8,3" Margin="7,0">Broswer</Button>
            <TextBlock Height="23" Name="tbk_ForderPath" Background="White" ForceCursor="True" Foreground="Red"/>
        </DockPanel>
        
        <GroupBox Grid.Row="2" Grid.ColumnSpan="3" Margin="7">
            <GroupBox.Header>
                <WrapPanel>
                    <TextBlock Text="{Binding ElementName= listbox1, Path=Items.Count}"/>
                    <TextBlock Padding="2,0,0,0"> file(s) found.</TextBlock>
                </WrapPanel>
            </GroupBox.Header>
            <ListBox Name="listbox1"  SelectionMode="Single">
                <ListBox.ContextMenu>
                    <ContextMenu>
                        <MenuItem Name="cmi2" Header="Delete selected files" />
                        <MenuItem Name="cmi3" Header="Clear"/>
                    </ContextMenu>
                </ListBox.ContextMenu>
            </ListBox>
        </GroupBox>
        
        <DockPanel Grid.Row="3" Margin="0" Name="dockPanel1" Grid.ColumnSpan="3">
            <Label Height="28" Name="label1" Margin="7,0,0,0">Status：</Label>
            <Button Height="23" Name="btn_Start" DockPanel.Dock="Right" Padding="8,3" Margin="7,0">Start</Button>
            <TextBlock Height="23" Name="tbk_Status" Background="White" Text=""/>
        </DockPanel>
        
        <ProgressBar Name="pBar" Grid.Row="4" Grid.ColumnSpan="3" Visibility="Hidden" />
        
    </Grid>
</Window>

Grid.Row="" 代表在几行, Grid.Column="" 代表在几列. RowSpan,ColumnSpan 代表跨几行,几列.  和HTML的table是一样的道理.

Padding=““  Margin=”“  这些都是定位这个位置,类似HTML的属性.

这个设置Window在屏幕中间:WindowStartupLocation="CenterScreen"

最好设置一下Window的最小大小,这样就不会把重要信息隐藏了.

MinWidth="550"
MinHeight="550"
WindowStyle="None"
