当设置为 false 时,我必须更改Text
组合框的属性,并且当同一控件为 trueIsEnabled
时,它可以从项目源中手动选择字段,这可能吗?IsEnabled
XAML:
<ComboBox Name="cmbIntervals"
Grid.Row="5"
Grid.Column="1"
Width="150"
HorizontalAlignment="Left"
VerticalAlignment="Top"
IsEnabled="{Binding ElementName=chkBox,
Path=IsChecked}"
ItemsSource="{Binding Source={x:Static res:Parameters.Instance},
Path=Intervals}"
Text="{Binding [Intervals], Mode=TwoWay,
UpdateSourceTrigger=PropertyChanged}" >
<ComboBox.Style>
<Style TargetType="{x:Type ComboBox}">
<Style.Triggers>
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Text" Value="1"/>
</Trigger>
</Style.Triggers>
</Style>
</ComboBox.Style>
</ComboBox>
