Silverlight删除数据表格中的数据,表格头部定义全选按钮,批量删除
实现的效果如图:
前台实现:
<UserControl.Resources>
<Style x:Key="DataGridColumnHeaderCheckBox" TargetType="data_primitives:DataGridColumnHeader">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="data_primitives:DataGridColumnHeader":>
<Grid Name="Root">
<CheckBox x:Name="CheckAll" Checked="CheckAll_Checked" Unchecked="CheckAll_Checked" />
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources><!--用户自定义资源,用于实现表格头部的全选-->
<Grid x:Name="LayoutRoot" Background="White" Height="421" Width="442">

<sdk:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<TextBlock Text="{Binding Name,Mode=TwoWay}" />
</DataTemplate>
</sdk:DataGridTemplateColumn.CellTemplate>
</sdk:DataGridTemplateColumn>
<sdk:DataGridTemplateColumn Header="删除操作">

后台实现:

set { isChecked = value; }
}
}
//List<Person> itemList = new List<Person>();
ObservableCollection<Person> itemList = new ObservableCollection<Person>();//动态的数据集合
public MainPage()
{
InitializeComponent();
itemList.Add(new Person { Name = "当当", Age = 45, IsMan = true,IsChecked=false });

//删除单个
