如何在C#中选中切换按钮时隐藏网格列

Question

在表单的右侧，我有一个网格，其中有两列，右列是"45〃；宽度和左边一个命名为"；LeftColumn"；被设置为"；"自动"；宽度。我想使用名为"的切换按钮的已检查和未检查事件；切换btn"以显示和隐藏"；LeftColumn"；

Answer 1

将名称添加到ColumnDefinition

<ColumnDefinition x:Name="ExchangeColumn" Width="0" />

<Button Clicked="OnExpandExchange" BackgroundColor="Transparent"/>

并使用以下方法

private void OnExpandExchange(object sender, EventArgs e)
{
if (ExchangeColumn.Width.Value == 0)
{
GetExpandAnimation().Commit(this, ExpandAnimationName, 16,
100,
Easing.CubicIn,
null, () => false);
}
else
{
GetCollapseAnimation().Commit(this, CollapssAnimationName, 16,
100,
Easing.CubicInOut,
null, () => false);
}
}
private Animation GetExpandAnimation()
{
return new Animation
{
{0, 1, new Animation(v => ExchangeColumn.Width= v, 0, 45)}
};
}
private Animation GetCollapseAnimation()
{
return new Animation
{
{0, 1, new Animation(v => ExchangeColumn.Width = v, 45, 0)}
};
}
