设置为modeTwoWay时，在UserControl的组合框中绑定到SelectedIndex的操作中断 [英] Binding to SelectedIndex in a Combobox in a UserControl breaks when setting to modeTwoWay

问题描述

由于某种原因，它还为某些(相同的)userControl绑定，而对于某些用户控件，它最初并没有绑定.

It also, for some reason, binds for some of the (identical) userControls and for some it does not bind in the first place.

那些绑定的对象，绑定可以从代码开始工作，但是从UI设置时会中断.请帮忙.

Those that bind, the binding works from code but breaks when set from the UI.  Please help.

< Grid.Column ="1" 边距 =" 10,0,0,0" Grid.Row ="1" Horizo​​ntalAlignment =左" VerticalAlignment =" Center" MinWidth ="50" x : 名称 SelectedIndex =&; { ElementName = TreatmentButton， 路径

<ComboBox Grid.Column="1" Margin="10,0,0,0" Grid.Row="1" HorizontalAlignment="Left" VerticalAlignment="Center" MinWidth="50" x:Name="LeftComboBox" SelectedIndex="{Binding ElementName=TreatmentButton, Path

= LeftTSelection}"// 

=LeftTSelection}"/> 

C#相关代码:  UserControl

public IEnumerable LeftCBValues { set {LeftComboBox.ItemsSource = 值 ; }}

public IEnumerable LeftCBValues { set { LeftComboBox.ItemsSource = value; } }

public 静态 DependencyProperty LeftTSelectionProperty = DependencyProperty .Register( "LeftTSelection" ， typeof ( typeof (

public static DependencyProperty LeftTSelectionProperty = DependencyProperty.Register("LeftTSelection", typeof(int), typeof(TreatmentButton));

public int LeftTSelection { 获取 { 返回 ( int )GetValue(LeftTSelectionProperty); } set {SetValue(LeftTSelectionProperty， 值 )； }}

public int LeftTSelection { get { return (int)GetValue(LeftTSelectionProperty); } set { SetValue(LeftTSelectionProperty,value); } }
