我有一个名为“Employee”的对象,如下:
class Employee
{
public string EmpName { get; set; }
public string Surname { get; set; }
public Employee(string Name, string Surname) : base()
{
this.EmpName = EmpName;
this.Surname = Surname;
}
public Employee()
{
}
}
我这里也有这个简单的“EmployeeControl”。网格中只有两个标签:
<UserControl x:Class="LabelBindingTest.EmployeeCtrl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
Name="EmpCtrl"
d:DesignHeight="120" d:DesignWidth="411">
<Grid>
<Label Content="{Binding ElementName=EmpCtrl, Path=EmpName}" Height="28" HorizontalAlignment="Left" Name="label1" VerticalAlignment="Top" Width="81" />
<Label Content="{Binding ElementName=EmpCtrl, Path=Surname}" Height="28" HorizontalAlignment="Right" Name="label2" VerticalAlignment="Top" Width="81" />
</Grid>
</UserControl>
(编辑)EmployeeControl 代码隐藏:
public partial class EmployeeCtrl : UserControl
{
Employee thisEmployee = new Employee();
public string EmpName
{
get
{
return thisEmployee.EmpName;
}
set
{
thisEmployee.EmpName = value;
}
}
public string Surname
{
get
{
return thisEmployee.EmpName;
}
set
{
thisEmployee.EmpName = value;
}
}
public EmployeeCtrl()
{
InitializeComponent();
}
}
现在,我要做的是将“EmployeeControl”添加到我的窗口并将它们绑定到 Employee 对象。这是我的“窗口”代码:
<Window x:Class="LabelBindingTest.MainWindow"
Name="myWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525" xmlns:my="clr-namespace:LabelBindingTest">
<Grid>
<my:EmployeeCtrl EmpName="Daniel" Surname="Hammond" HorizontalAlignment="Left" Margin="23,26,0,0" x:Name="employeeCtrl1" VerticalAlignment="Top" Height="97" Width="429" />
</Grid>
</Window>
我已经尝试了很多东西,但我就是无法让它发挥作用。它编译得很好,但标签是空的。我只想将我的“Employee”对象附加到“EmployeeCtrl”控件。关于我如何解决这个问题的任何想法?我今天读了很多关于装订的书,但我还在摸不着头脑。我不确定是否需要实现 INotifyPropertyChanged,因为我现在只在运行时之前设置员工姓名。
(编辑):我已经下载了 Caliburn.Micro 并在上一个答案中使用了相同的代码。同样的结果,空的窗口。
这是整个项目。不过,它的所有代码都应该粘贴在这个问题中。这只是为了方便。
