在Silverlight中向ListBox的ItemTemplate添加行样式,可以通过以下步骤实现:
<ListBox x:Name="myListBox">
<ListBox.ItemTemplate>
<DataTemplate>
<!-- Add your item template here -->
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<ListBox x:Name="myListBox">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<ListBoxItem.Style>
<Style TargetType="ListBoxItem">
<Setter Property="Background" Value="LightGray" />
<Style.Triggers>
<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="DarkGray" />
</Trigger>
</Style.Triggers>
</Style>
</ListBoxItem.Style>
<!-- Add your item content here -->
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
在上述代码中,我们为ListBoxItem设置了一个样式,其中设置了默认的背景颜色为LightGray,并使用触发器在选中时将背景颜色改为DarkGray。
public class MyStyleSelector : StyleSelector
{
public Style Style1 { get; set; }
public Style Style2 { get; set; }
public override Style SelectStyle(object item, DependencyObject container)
{
// Implement your logic to select the appropriate style based on the item
// For example, you can check the properties of the item and return the corresponding style
// In this example, we'll alternate between Style1 and Style2
if (container is ListBoxItem listBoxItem)
{
int index = listBoxItem.GetIndex();
return index % 2 == 0 ? Style1 : Style2;
}
return base.SelectStyle(item, container);
}
}
<ListBox x:Name="myListBox" ItemContainerStyleSelector="{StaticResource myStyleSelector}">
<ListBox.Resources>
<local:MyStyleSelector x:Key="myStyleSelector">
<local:MyStyleSelector.Style1>
<Style TargetType="ListBoxItem">
<Setter Property="Background" Value="LightGray" />
</Style>
</local:MyStyleSelector.Style1>
<local:MyStyleSelector.Style2>
<Style TargetType="ListBoxItem">
<Setter Property="Background" Value="DarkGray" />
</Style>
</local:MyStyleSelector.Style2>
</local:MyStyleSelector>
</ListBox.Resources>
<ListBox.ItemTemplate>
<DataTemplate>
<!-- Add your item content here -->
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
在上述代码中,我们首先在ListBox的Resources中定义了一个MyStyleSelector实例,并为其设置了两个样式Style1和Style2。然后,将该实例赋值给ListBox的ItemContainerStyleSelector属性。
通过以上步骤,你可以在Silverlight中向ListBox的ItemTemplate添加行样式。根据需要,你可以选择为所有ListBox项应用相同的样式,或者根据数据项选择不同的样式。
