wpf – 如何绑定文本框和属性？

概述<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xa

<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit"    xmlns:System_windows_Controls_Primitives="clr-namespace:System.windows.Controls.Primitives;assembly=System.windows.Controls.Toolkit"    x:Class="SilverlightApplication5.MainPage"    WIDth="640" Height="480">    <StackPanel x:name="LayoutRoot" Background="White">        <TextBox x:name="tbWIDth" textwrapPing="Wrap"            Text="{Binding Mode=TwoWay,ValIDatesOnExceptions=True,Path=RoomWIDth}"/>        </StackPanel></UserControl>

RoomWIDth – 属性.

using System;using System.Collections.Generic;using System.linq;using System.Net;using System.windows;using System.windows.Controls;using System.windows.documents;using System.windows.input;using System.windows.Media;using System.windows.Media.Animation;using System.windows.Shapes;namespace SilverlightApplication5{    public partial class MainPage : UserControl    {        public MainPage()        {            InitializeComponent();        }        private int roomWIDth = 10;        public int RoomWIDth        {            get { return roomWIDth; }            set            {                if (value < 0 || value > 100)                {                    throw new Exception("Data not correct");                }                roomWIDth = value;            }        }    }}

我需要添加到Binding源这个类.这是怎么回事？

解决方法 使用Elementname例如：

<UserControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="http://schemas.microsoft.com/winfx/2006/xaml/presentation/toolkit" xmlns:System_windows_Controls_Primitives="clr-namespace:System.windows.Controls.Primitives;assembly=System.windows.Controls.Toolkit"    x:Class="SilverlightApplication5.MainPage"    WIDth="640" Height="480"    name="control">    <!-- ... -->    <TextBox Text="{Binding Elementname=control,Mode=TwoWay,Path=RoomWIDth}" x:name="tbWIDth" textwrapPing="Wrap"/>

如果您遇到类似基本绑定的问题,那么您应该阅读它. (WPF/Silverlight)
