如何通过 wpf 中的行和列获取网格子项?

how to get grid children by its row and column in wpf?(如何通过 wpf 中的行和列获取网格子项?)

问题描述

<Grid x:Name="LayoutRoot" HorizontalAlignment="Center" VerticalAlignment="Center" >
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="Auto"/>
        <ColumnDefinition Width="Auto"/>
    </Grid.ColumnDefinitions>
    <Button Width="150" Height="50" x:Name="Btn1" Content="Button1" Grid.Row="0" Grid.Column="0"/>
    <Button Width="150" Height="50" x:Name="Btn2" Content="Button2" Grid.Row="0" Grid.Column="1"/>
    <Button Width="150" Height="50" x:Name="Btn3" Content="Button3" Grid.Row="2" Grid.Column="0"/>
    <Button Width="150" Height="50" x:Name="Btn4" Content="Button4" Grid.Row="2" Grid.Column="1"/>
</Grid>

Visual childVisual = (Visual)VisualTreeHelper.GetChild(LayoutRoot,0);

根据 Grid.Children/library/system.windows.controls.grid.getrow.aspx">Grid.GetRow 和 GetColumn 为每个孩子返回.

Filter the Grid.Children based on what Grid.GetRow and GetColumn returns for every child.

例如

var itemsInFirstRow = LayoutRoot.Children
                          .Cast<UIElement>()
                          .Where(i => Grid.GetRow(i) == 0);
