如何将 ComboBox 中的项目设置为“SelectedText"加载中动态组合框的属性

问题描述

在 WinForm 中，我有一个 ComboBox.我正在尝试做这样的事情.

In WinForm, I have a ComboBox. I am trying to do something like this.

当 ComboBox 只有 1 个项目时，该项目应设置为 ComboBox 的选定文本"，并且当它有超过 1 项时，第一项应设置为选定文本".

When ComboBox has only 1 item, that item should be set as "Selected Text" for ComboBox,and when it has items more than 1, first item should be set as "Selected Text".

我希望这在 Form Load 时发生.

I want this to be happened at the time of Form Load.

我该怎么做?

推荐答案

如果我理解正确的话，您希望组合框的第一项被选择/显示在组合框中.

If I understand it the right way, you want the first item of the combobox to be selected/shown in comboBox.

这很简单:

comboBox1.SelectedIndex = 0; //This will select the first item in the combobox (zero based numbering)

要在表单显示后立即设置，只需将其放在

To set it right after the form is shown simply put it after

InitializeComponent();

适当的形式.
