WPF中GridSplitter控件的使用

先看一下效果，左边是一个树形列表，右边是选中后的说明。

实现起来也很简单： 

 <Grid Margin="0,32,0,28" Name="gridMain" Loaded="TreeViewItem_Loaded">
            <Grid.ColumnDefinitions>
                <ColumnDefinition Width="70*"/>
                <ColumnDefinition Width="30*"/>
            </Grid.ColumnDefinitions>           
            <GridSplitter Width="5" Loaded="TreeViewItem_Loaded"></GridSplitter>
            <TreeView FontSize="14" Grid.Row="0" Grid.Column="0" Margin="0,0,5,0" Name="trvList" Loaded="TreeViewItem_Loaded">
             </TreeView>
            <Label Background="LightGreen" VerticalContentAlignment="Center" HorizontalContentAlignment="Center" Grid.Row="0" Grid.Column="1" Loaded="TreeViewItem_Loaded" />
</Grid>
