问题描述

我的XAML代码是这样的:

My XAML code is like this:

<Window
    xmlns                 ='http://schemas.microsoft.com/netfx/2007/xaml/presentation'
    xmlns:x               ='http://schemas.microsoft.com/winfx/2006/xaml'
    Title                 ='Print Preview - More stuff here'
    Height                ='200'
    Width                 ='300'
    WindowStartupLocation ='CenterOwner'>
    <DocumentViewer Name='dv1' ... />
</Window>

如何在XAML或C#中消除搜索框?

How can I, in XAML or in C#, eliminate the search box?

推荐答案

使我研究了如何以编程方式获取保存有查找工具栏的ContentControl.我真的不想为DocumentViewer编写一个全新的模板.我只想更改(隐藏)一个控件.这就将问题简化为如何检索通过模板应用的控件?.
这是我发现的:

Vlad's answer led me to look at how to programmatically grab the ContentControl that holds the find toolbar. I didn't really want to write an entirely new template for the DocumentViewer; I wanted to change (hide) only one control. That reduced the problem to how to retrieve a control that is applied via a template?.
Here's what I figured out:

  Window window = ... ;
  DocumentViewer dv1 = LogicalTreeHelper.FindLogicalNode(window, "dv1") as DocumentViewer;
  ContentControl cc = dv1.Template.FindName("PART_FindToolBarHost", dv1) as ContentControl;
  cc.Visibility = Visibility.Collapsed;
