没有下拉按钮的 WPF ComboBox [英] WPF ComboBox without drop-down button

问题描述

我想要一个 ComboBox，它没有下拉按钮，但当我点击 ComboBox 中的文本时仍然可以打开.这可以用 WPF ComboBox 实现吗?

I want a ComboBox which has no drop-down button but can still be opened when I click on the text in the ComboBox. Is this possible with a WPF ComboBox?

推荐答案

这是可能的，但您需要重新设计它以达到完美.您可以通过如下覆盖系统参数来获得大部分方法:

It's possible, but you would need to retemplate it to achieve perfection. You can get most of the way there by overriding a system parameter as follows:

<ComboBox xmlns:sys="clr-namespace:System;assembly=mscorlib">
    <ComboBox.Resources>
        <sys:Double x:Key="{x:Static SystemParameters.VerticalScrollBarWidthKey}">0</sys:Double>
    </ComboBox.Resources>
    <ComboBoxItem>One</ComboBoxItem>
    <ComboBoxItem>Two</ComboBoxItem>
    <ComboBoxItem>Three</ComboBoxItem>
</ComboBox>

但是，它并不完美，因为焦点矩形仍然假定存在下拉按钮.

However, it isn't perfect because the focus rectangle still assumes there is a drop-down button present.
