c# - C#/WPF Grid MaxWidth in relation to screen resolution

Question

I've got 2 Columns that are divided by a GridSplitter. And I want to set the MaxWidth of the columns in percentage (e.g. 5*) but it doesn't work. Is there any other way to do it?

<Grid.ColumnDefinitions>
      <ColumnDefinition Width="6*"  />
      <ColumnDefinition Width="Auto"  />
</Grid.ColumnDefinitions>
<GridSplitter ResizeDirection="Columns"
              Grid.Column="0"
              HorizontalAlignment="Right"
              VerticalAlignment="Stretch"
              Height="auto"
              Background="#c1c1c1"
              BorderBrush="#c1c1c1"
              BorderThickness="1"/>

Answer 1

如果您检查MSDN文档中的ColumnDefinition,MinWidth和MaxWidth是 类型double，而不是像Width属性，这是类型GridLength- 这就是为什么它支持Auto，*作为宽度的有效值。因此，根据百分比指定 MinWidth、MaxWidth 并不是一件简单的事情。

但是，您可以编写一个Converter，它可以Auto, *作为输入值并进行数学运算，然后为 MaxWidth 设置一个有效值。
