在GridView中访问Grid以编程方式操作其宽度

Question

    <GridView x:Name="MainGridView">
            <ItemsPanelTemplate>
                <StackPanel Orientation="Vertical"/>
            </ItemsPanelTemplate>
        </GridView.ItemsPanel>
        <GridView.ItemTemplate>
            <DataTemplate x:DataType="viewModels:SomeViewModel">
                <Grid x:Name="I_NEED_THIS">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="40*"/>
                        <ColumnDefinition Width="60*"/>
                        <ColumnDefinition Width="180*"/>
                        <ColumnDefinition Width="40*"/>
                        <ColumnDefinition Width="40*"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock with some binding/>
                    <TextBlock with some binding/>
                    <TextBlock with some binding/>
                    <TextBlock with some binding/>
                    <TextBlock with some binding/>
                </Grid>
            </DataTemplate>
        </GridView.ItemTemplate>
    </GridView>

我需要在运行时访问每个Grid（x：Name =＆＃34; I_NEED_THIS＆＃34;）以在运行时操作一些网格参数。我如何可以遍历创建的每个网格？

实际上，您必须遍历Visual Tree并找到您想要进行更改的元素。这篇博客文章可以帮助您入门：
