wpf grid怎么隐藏一列?
<Grid Margin="0,-24,0,2" x:Name="dataGrid1">
<Grid.ColumnDefinitions >
<ColumnDefinition Width="89"/>
<ColumnDefinition Width="423"/>
<ColumnDefinition Width="480"/>
<ColumnDefinition Width="100" />
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="103*"/>
<RowDefinition Height="30*"/>
<RowDefinition Height="237*"/>
<RowDefinition Height="30*"/>
<RowDefinition Height="181*"/>
</Grid.RowDefinitions>
我要把第一列 <ColumnDefinition Width="89"/> 进行隐藏和显示转换,请问如何来做呢?
