停止comboBox的selectedIndexChanged事件触发表单加载 [英] Stop comboBox's selectedIndexChanged event from firing when the form loads

问题描述

我有一个带有 ComboBox 的表单，提供了一个下拉列表。在comboBox的 SelectedIndexChanged事件中，我运行一些代码，但我不希望该代码在表单加载时运行。不幸的是，当我加载窗体（在组合框中进行选择之前），组合框的 SelectedIndexChanged 触发（我想当组合框是数据绑定）。有没有办法避免这种行为？

I have a form with a ComboBox that provides a dropdownlist. On the comboBox's SelectedIndexChanged event, am running some code, but I don't want that code to run when the form loads. Unfortunately, when I load the form (before I make a selection in the combobox), SelectedIndexChanged of the combobox fires (I think when the combobox is databinding). Is there a way of avoiding such behaviour?

推荐答案

如果您只想在用户更改组合中的选定项目时做出反应框，那么最好订阅 SelectionChangeCommitted 。

If you want to react only when the user change the selected item in the combo box, then it is better to subscribe to SelectionChangeCommitted.
