WPF-Grid使用

Grid设置行和列

Grid.RowDefinitions

Grid.RowDefinitions用于设置行数量，在的标签中添加 元素，有几个元素表示有几行。
例如两行

<Grid.RowDefinitions>
            <RowDefinition>RowDefinition>
            <RowDefinition>RowDefinition>
Grid.RowDefinitions>

Grid.ColumnDefinitions

Grid.ColumnDefinitions用于设置列数量，在的标签中添加 元素，有几个元素表示有几列。
例如三列

<Grid.ColumnDefinitions>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
Grid.ColumnDefinitions>

完整两行三列代码
ShowGridLines=”True”用于设置程序运行后显示网格线，在测试环境中使用

<Window x:Class="combination.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="396" Width="502">
    <Grid ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition>RowDefinition>
            <RowDefinition>RowDefinition>
        Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
        Grid.ColumnDefinitions>
    Grid>
Window>

设置元素在Grid中的位置

使用Grid.Row和Grid.Column的数值设定第几行第几列， Grid.Row=”0” Grid.Column=”0”表示第0行第0列。如图代码展示出的按钮位置。

<Window x:Class="combination.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="396" Width="502">
    <Grid ShowGridLines="True">
        <Grid.RowDefinitions>
            <RowDefinition>RowDefinition>
            <RowDefinition>RowDefinition>
        Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
            <ColumnDefinition>ColumnDefinition>
        Grid.ColumnDefinitions>
        <Button Content="Button" Grid.Row="0" Grid.Column="0" />
        <Button Content="Button" Grid.Row="0" Grid.Column="1"/>
        <Button Content="Button" Grid.Row="1" Grid.Column="2"/>
    Grid>
Window>

调整Grid行列的尺寸

1.设置绝对尺寸Width和Height
2.设置自动尺寸，满足容器大小
3.比例设置尺寸。

<Grid.ColumnDefinitions>
            <ColumnDefinition Width="*">ColumnDefinition>
            <ColumnDefinition Width="2*">ColumnDefinition>
            <ColumnDefinition Width="4*">ColumnDefinition>
Grid.ColumnDefinitions>

UseLayoutRounding 抗锯齿，处理Grid分配后不为整数的情形Grid.ColumnSpan和Grid.RowSpan设置元素跨行或者跨列

分割线GridSplitter

代码使用GridSplitter属性后的效果如下

<Window x:Class="combination.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="396" Width="502">
    <Grid >
        <Grid.RowDefinitions>
            <RowDefinition>RowDefinition>
            <RowDefinition>RowDefinition>
        Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*" >ColumnDefinition>
            <ColumnDefinition Width="Auto" >ColumnDefinition>
            <ColumnDefinition Width="2*">ColumnDefinition>
            <ColumnDefinition Width="4*">ColumnDefinition>
        Grid.ColumnDefinitions>
        <Button Content="Button" Grid.Row="0" Grid.Column="0" />
        <Button Content="Button" Grid.Row="0" Grid.Column="2"/>
        <Button Content="Button" Grid.Row="1" Grid.Column="3"/>
        <GridSplitter Grid.Column="1" Width="3" Grid.RowSpan="2" VerticalAlignment="Stretch" HorizontalAlignment="Center"/>
    Grid>
