何时在WPF中使用用户控件 [英] When to use User Controls in WPF

问题描述

我有一个看法，过滤一个DataGrid，我想使用相同的集合的完全相同的过滤（除了列将是不同的）在不同的视图。

当然，我不想在这个新视图中复制XAML，所以当用户控件是正确的事情吗？

我唯一的问题是，新的DataGrid将被放置在新视图的下面，这样可能吗？而且正如我上面所说的那样，这些列在过滤中可能会有所不同，所以在用户控制中再次有可能出现这种情况？

感谢

解决方案

想要创建一个UserControl一种新的UI控件，或者导出一个现有的控件，并增强其功能。

你需要的是一个样式，你想要设置certian属性您对证书价值的控制：

 < Style TargetType =Button> 
< Setter Property =BackgroundValue =Red/> 
< Setter Property =Template> 
< Setter.Value> 
< ControlTemplate TargetType =Button> 
< Grid> 
< Rectangle Fill ={TemplateBinding Background/> 
< ContentPresenter /> 
< / Grid> 
< / ControlTemplate> 
< /Setter.Value> 
< / Setter> 
< / Style> 
  

I have a view that Filters a DataGrid and I want to use the the exact same filtering with the same collection (apart from the columns will be different) in a different view.

Of course I dont want to duplicate the XAML in this new view, so is this when a user control would be the correct thing to do?

My only problem is that a new DataGrid will be put underneath in the new view so would this be possible? And as I said above, the columns also may be different in the filtering, so again, possible within a user control?

Thanks

A UserControl should be used when wanting to create a new kind of control for your UI, or derive an existing control and enhance its capabilities.

What you need sounds like a Style, where you want to set certian properties of your control to certian values:

<Style TargetType="Button">
  <Setter Property="Background" Value="Red"/>
  <Setter Property="Template">
     <Setter.Value>
         <ControlTemplate TargetType="Button">
             <Grid>
                 <Rectangle Fill="{TemplateBinding Background"/>
                 <ContentPresenter/>
             </Grid>
         </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>
