我有类:如何更新样式的内容?
class NoExp : Expander
{
public long Id { get; set; }
public string btnBackGround { get;set;}
public bool btnEnabled { get; set; }
public string btnForeground { get; set; }
public string tbText { get; set; }
public string tbTime { get; set; }
public string tbNumber { get; set; }
public string tbForeground { get; set; }
public ServiceReference.PickerItemItem[] DGItemSource { get; set; }}
和样式:
<Style x:Key="ExpanderStyle" TargetType="{x:Type local:NoExp}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type local:NoExp}">
<Grid>
<Button Content="Собран" Height="35.5" Margin="5,0,1,0" VerticalAlignment="Top"
Foreground="{Binding btnForeground, RelativeSource={RelativeSource TemplatedParent}}"
Background="{Binding btnBackGround, RelativeSource={RelativeSource TemplatedParent}}"
IsEnabled="{Binding btnEnabled, RelativeSource={RelativeSource TemplatedParent}}"
Tag="{Binding Id, RelativeSource={RelativeSource TemplatedParent}}"
Style="{DynamicResource ButtonStyle1}" Click="Button_Click_1"/>
在代码中,我试图改变:
foreach (NoExp exp in listBox.Items)
{
exp.btnForeground = "#808080";
}
数据的变化,但在界面上没有变化。请告诉我应该怎么做。
分配风格忘了。当创建一切工作,因为它应该。更新出现问题。 – Kirill
