想在silverlight的datagrid中添加一个列头控件，checkbox
首先添加资源文件，app也要用相应的设置，资源文件如下：
<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d">
<!-- 应该在此定义资源字典条目。-->
<Style x:Key="DataGridColumnHeaderStyle1" TargetType="sdk:DataGridColumnHeader">
<Setter Property="Foreground" Value="#FF000000"/>
<Setter Property="HorizontalContentAlignment" Value="Left"/>
<Setter Property="VerticalContentAlignment" Value="Center"/>
<Setter Property="IsTabStop" Value="False"/>
<Setter Property="SeparatorBrush" Value="#FFC9CACA"/>
<Setter Property="Padding" Value="4"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="sdk:DataGridColumnHeader">
<Grid x:Name="Root">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<VisualStateManager.VisualStateGroups>

<Grid HorizontalAlignment="{TemplateBinding
HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding
VerticalContentAlignment}">
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<ContentPresenter >
<ContentPresenter.Content>
<CheckBox Margin="0,0,56,0" Content="选择Foreground="Green"/>
</ContentPresenter.Content>
</ContentPresenter>
<Path x:Name="SortIcon" Grid.Column="1" Data="F1 M -5.215,6.099L
5.215,6.099L 0,0L -5.215,6.099 Z " Fill="#FF444444"
HorizontalAlignment="Left" Margin="4,0,0,0" Opacity="0"
RenderTransformOrigin=".5,.5" Stretch="Uniform"
VerticalAlignment="Center" Width="8">
<Path.RenderTransform>
<ScaleTransform ScaleY=".9" ScaleX=".9"/>
</Path.RenderTransform>
</Path>
</Grid>
<Rectangle x:Name="VerticalSeparator" Grid.Column="1"
Fill="{TemplateBinding SeparatorBrush}" Visibility="{TemplateBinding
SeparatorVisibility}" VerticalAlignment="Stretch" Width="1"/>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ResourceDictionary>
然后在grid中对应列添加如下代码:
<data:DataGridTemplateColumn HeaderStyle="{StaticResource DataGridColumnHeaderStyle1}">
这样一切都搞定啦。
效果如下：
方法二:
在页面内部添加资源:
<UserControl.Resources>
<Style x:Key="checkHeader" TargetType="sdk:DataGridColumnHeader">
<Setter Property="ContentTemplate">
<Setter.Value>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBlock Text=" "></TextBlock>
<CheckBox x:Name="headChoice" Click="chChoiceHeader_Click" HorizontalAlignment="Center"></CheckBox>
</StackPanel>
</DataTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
添加完以后,在gird列定义时添加如下代码:
<sdk:DataGridTemplateColumn Width="50" HeaderStyle="{StaticResource checkHeader}">
<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox x:Name="cbChoice" HorizontalAlignment="Center"></CheckBox>
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>就可以了.
麻烦的地方在于每个地方都要填加.
在程序后台获取的方法是:
CheckBox
button = this.gridManager.Columns[this.gridManager.Columns.Count -
1].GetCellContent(item).FindName("cbChoice") as CheckBox;
