dataform里ComboBox 的SelectedIndex的问题:
cb.SelectedIndex = 0;//这里设定后，后面不管ComboBox 的SelectionChanged事件如何变化，cb.SelectedIndex始终等于0，请问这里如何修改呢？
前台：
<toolkit:DataForm HorizontalAlignment="Left" Name="dataForm1" VerticalAlignment="Top" Height="161" Width="378" ContentLoaded="dataForm1_ContentLoaded">
<toolkit:DataForm.EditTemplate>
<DataTemplate>
<StackPanel>
<toolkit:DataField Label="事业部名称*">
<ComboBox Margin="3" Name="cbUnit" SelectionChanged="cbUnit_SelectionChanged" />
</toolkit:DataField>
<toolkit:DataField Label="部门名称*">
<TextBox Margin="3" Text="{Binding DepartmentName, Mode=TwoWay,NotifyOnValidationError=True, ValidatesOnExceptions=True }" Name="texDepartmentName" />
</toolkit:DataField>
</StackPanel>
</DataTemplate>
