当表单加载时停止组合框的 selectedIndexChanged 事件 [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，它提供了一个下拉列表.在组合框的 SelectedIndexChanged 事件 上，正在运行一些代码，但我不希望该代码在表单加载时运行.不幸的是，当我加载表单时(在我在组合框中进行选择之前)，组合框的 SelectedIndexChanged 会触发(我认为当组合框是 databinding 时).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

如果你想只在用户改变组合框中的选中项时做出反应，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.
