我有類:如何更新樣式的內容?
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; }}
和樣式:
<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"/>
在代碼中,我試圖改變:
foreach (NoExp exp in listBox.Items)
{
exp.btnForeground = "#808080";
}
數據的變化,但在界面上沒有變化。請告訴我應該怎麼做。
分配風格忘了。當創建一切工作,因爲它應該。更新出現問題。 – Kirill
