推荐答案

删除 SelectedIndex_Changed 事件的处理程序，绑定数据，然后重新添加处理程序.以下是如何在方法中完成此操作的简单示例:

Remove the handler for the SelectedIndex_Changed event, bind your data, then add the handler back. Following is a simple example of how this might be done within a method:

private void LoadYourComboBox()
{
    this.comboBox1.SelectedIndexChanged -= new EventHandler(comboBox1_SelectedIndexChanged);


        // Set your bindings here . . .


    this.comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_SelectedIndexChanged);
}
