我在 xaml 中创建了一个自定义依赖对象,我想将它的整个实例绑定到另一个自定义依赖对象的属性。控件内部发生的所有事情。例如像这样的东西
class row : dependencyobject
{
// this is a dp property
public static readonly dependencyproperty widthproperty = dependencyproperty.register...
}
class cell : dependencyobject
{
public static readonly dependencyproperty dataproperty = dependencyproperty.register....
}
class customGridView:Control
{
List<Row>Rows { get;set;}
List<Cell> Cells { get;set;}
}
现在我想将一个行的实例绑定到 cell.data 属性,也是这样的:
<customGridView>
<row x:name:row1 width=200/> (this is a class that derives for dependencyobject)
<row .../>
<cell data={Binding ElementName=row1}/> (this is another class that derives from dependencyobj and tries to bind to entire instance of row class)
<cell ..../>
<cell ..../>
</customGridView/>
有什么帮助吗?
根据需要,这是 cell.data 的 dp 属性:
public Row Data
{
get { return (Row)GetValue(DataProperty); }
set { SetValue(DataProperty, value); }
}
// Using a DependencyProperty as the backing store for ColumnName. This enables animation, styling, binding, etc...
public static readonly DependencyProperty DataProperty=
DependencyProperty.Register("Data", typeof(Row), typeof(Cell), new PropertyMetadata(null));
