WPF：无下拉按钮的ComboBox

问题描述：

我想要一个ComboBox没有下拉按钮，但是当我点击组合框中的文本仍然可以打开。
这是可能与一个WPF组合框吗？

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

答

这可能，但你需要retemplate它达到完美。您可以通过覆盖系统参数来获得大部分的方式，如下所示：

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>
    <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，这不是完美的，因为焦点矩形仍然假设有一个下拉按钮。

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