推荐答案

删除处理程序SelectedIndex_Changed事件，绑定您的数据，然后再添加处理程序了。以下是如何可能的方法内完成一个简单的例子：

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);
}
