在comboBox控件中选择数据 [英] Selecting a data in a comboBox control

问题描述

在我的Windows窗体应用程序的comboBox1中，有超过100个学生名称可用。 comboBox1按字母顺序排序。如果用户想要选择以R开头的名称，则用户必须滚动comboBox1以选择该特定名称，这是一种耗时的方法。我想应用一个设施，比如当用户写第一个字母R时，只有以R开头的名称应该在comboBox1中突出显示，如果再次用户写第二个字母就像RA一样，应该显示以RA开头的名字。但我不知道怎么做？请有人通过提供正确的代码来帮助我。

In a comboBox1 in my Windows Form Application, there are more than 100 Student Name available. The comboBox1 is sorted alphabetically. If the user wants to select a name starting with R, the user has to scroll the comboBox1 to select that particular name which is a time consuming method. I want to apply a facility like when the user write the first letter R, only the name starting with R should be highlighted in the comboBox1, if again the user write the second letter like RA the name starting with RA should be displayed. But I don’t know how to do this? Please somebody help me by giving proper codes.
