c# – 防止重新排序第一列

我有一个listview,其中包含gridcolumns的网格视图,我想重新排序除第一列以外的所有列.我怎样才能做到这一点？另外我想保存新列位置.

我的listview代码是：

<Style x:Key="myListViewStyle" targettype="{x:Type ListView}"  x:Shared="False">
        <Setter Property="BorderBrush" Value="RoyalBlue" />
        <Setter Property="Foreground"  Value="teal" />
        <Setter Property="FontSize" Value="14" />
        <Setter Property="Margin" Value="20,60,20,50" />
        <Setter Property="BorderThickness" Value="4,4,4" />
        <Setter Property="ListView.View">
            <Setter.Value>
                <GridView AllowsColumnReorder="True" >
                    <GridView.Columns>
                        <GridViewColumn Header="A/A" Width="30" displayMemberBinding="{Binding AA}"></GridViewColumn>
                        <GridViewColumn Header="Price" Width="350" displayMemberBinding="{Binding Price}" >
                        </GridViewColumn>
                        <GridViewColumn Header="Shop" Width="200" displayMemberBinding="{Binding Shop}" >
                        </GridViewColumn>
                    </GridView.Columns>
                </GridView>
            </Setter.Value>
        </Setter>
    </Style>

我也用这样的代码创建listview：

ListView l1 = new ListView();
 l1.Style = Resources["myListViewStyle"] as Style;

解决方法

如果它只是你想要kepp的第一列,试试这个：

XAML：

<GridViewColumnHeader x:Name="FirstColumn" MouseMove="PreventDrag">

代码背后：

public MyWindow()
{
    InitializeComponent();
    (MyListview.View as GridView).Columns.CollectionChanged += ColumnsReordered;
}

private void PreventDrag(object sender,MouseEventArgs e)
{
    if (e.LeftButton == MouseButtonState.pressed)
        e.Handled = true;
}

private void ColumnsReordered(object sender,NotifyCollectionChangedEventArgs e)
{
    if (e.Action == NotifyCollectionChangedAction.Move)
    {
        var columns = sender as GridViewColumnCollection;
        if (columns != null)
            dispatcher.BeginInvoke((Action)(() => columns.Move(columns.IndexOf(FirstColumn.Column),0)));
    }
}
