数据绑定类的定义
说明：可以在类中输入propdp，按两下Tab键，自动带出依赖属性的代码,这是一个快捷键
public class FData2:DependencyObject //注意要继承DependencyObject
{
//定义三个依赖属性
public static readonly DependencyProperty FSelectedProperty;
public static readonly DependencyProperty FItem2Property;
public static readonly DependencyProperty FItemProperty;
static FData2()
{
//在构造函数中注册三个依赖属性
//DependencyProperty.Register 参数说明,1:FSelected,暴露给外面的属性,2:typeof(bool)，属性的类型
// 3:typeof(FData2),填写类名,4:new PropertyMetadata(false) 里面的false为属性初始化时的默认值
FSelectedProperty =
DependencyProperty.Register("FSelected",typeof(bool),typeof(FData2),new PropertyMetadata(false));
FItemProperty =
DependencyProperty.Register("FItem",typeof(string),new PropertyMetadata(""));
FItem2Property =
DependencyProperty.Register("FItem2",new PropertyMetadata(""));
}
public bool FSelected
{
get { return (bool)GetValue(FSelectedProperty); }
set { SetValue(FSelectedProperty,value); }
}
public string FItem
{
get { return (string)GetValue(FItemProperty); }
set { SetValue(FItemProperty,value); }
}
public string FItem2
{
get { return (string)GetValue(FItem2Property); }
set { SetValue(FItem2Property,value); }
}
}
====================================================================================
List<FData2> lst = null;
public RadGridView用数据绑定方式实现复选框全选全清()
{
InitializeComponent();
lst = new List<FData2>(){
new FData2{FSelected=false,FItem="内容1",FItem2="内容1-2"},
new FData2{FSelected=false,FItem="内容2",FItem2="内容2-2"},FItem="内容3",FItem2="内容3-2"},FItem="内容4",FItem2="内容4-2"},FItem="内容5",FItem2="内容5-2"},FItem="内容6",FItem2="内容6-2"}};
dgList.ItemsSource = lst;
}
private void btnSelectAll_Click(object sender,RoutedEventArgs e)
{
SelCheckBox(true);
}
private void btnClearall_Click(object sender,RoutedEventArgs e)
{
SelCheckBox(false);
}
private void SelCheckBox(bool bSel)
{
for (int i = 0; i < lst.Count; i++)
{
lst[i].FSelected = bSel; //由于定义了依赖属性，所以这里数据一改变，界面上的复选框也跟着改变，文本也一样
if (bSel)
{
lst[i].FItem = "选择";
}
else
{
lst[i].FItem = "非选择";
}
}
}
====================================================================================
//复选框选择的的一个转换类
public class SelDataConvert : System.Windows.Data.IValueConverter
{
public object Convert(object value,Type targettype,object parameter,System.Globalization.CultureInfo culture)
{
bool bSel = (bool)value;
return bSel;
}
public object ConvertBack(object value,System.Globalization.CultureInfo culture)
{
bool bSel = (bool)value;
return bSel;
}
}
====================================================================================
关键代码
<navigation:Page.Resources>
<local:SelDataConvert x:Key="SelCTS" />
</navigation:Page.Resources>
定义转换器资源
<CheckBox IsChecked="{Binding FSelected,Mode=TwoWay,Converter={StaticResource SelCTS}}"/>
使用双向绑定，使用SelCTS转换器
