如何更改comboBox.Text一个comboBox.SelectedIndexChanged事件中？ [英] How do I Change comboBox.Text inside a comboBox.SelectedIndexChanged event?

问题描述

代码示例：

private void comboBox_SelectedIndexChanged(object sender, EventArgs e)
{
    if(some condition)
    {
    	comboBox.Text = "new string"
    }
}

我的问题是对ComboBox文本始终显示所选指标的字符串值，而不是新的字符串。是一个解决方法呢？

My problem is that the comboBox text always shows the selected index's string value and not the new string. Is the a way round this?

推荐答案

此代码应工作...

public Form1()
{
    InitializeComponent();

    comboBox1.Items.AddRange(new String[] { "Item1", "Item2", "Item3" });
}

private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    String text = "You selected: " + comboBox1.Text;

    BeginInvoke(new Action(() => comboBox1.Text = text));
}
