使组合框的下拉菜单更短? [英] Make the dropdown of a combobox be shorter?

问题描述

有点困惑.我有一个数据绑定到字符串列表的组合框.在过去，我记得如果我只有一两个东西，组合框就会很短.但是现在组合框大约是 5 个项目的高度，即使少于 5 个项目(空白下拉框的高度).我需要改变什么来解决这个问题?我玩过 Maxdropdown，没有任何变化.

Mildly confused. I have a combobox that is databound to a list of strings. In the past I recall the combobox being short if I only had one or two things in it. But now the combobox is about the height of 5 items, even when there's less than 5 items (the height of a blank drop down). What do I need to change to fix this? I've played with Maxdropdown with no changes.

推荐答案

您可以覆盖 Template，如果您的控件已经使用 costom 模板设置样式，则 MaxDropDownHeight 属性可能是模板内没有正确绑定，在这种情况下更改它不会做任何事情.

You can override the Template, if your control is already styled with a costom template it could be the case that the MaxDropDownHeight property is not properly bound inside the template, in this case changing it will not do anything.
