推荐答案

要通过代码绑定组合框 - 你可以这样做：



combobox.datasource = yourdata;

combobox.DataValueField =FieldFromYourDataToReturn;

combobox.DataTextField =FieldFromYourDataToShow;





要不显示元素 - 您可以像下面一样删除它：

combobox.Items.RemoveAt（combobox.Items.Count-1 ）;

或者你可以确保它从未被选中 - 这可能是一个更好的解决方案。

To bind the combobox through code - you would do something like:

combobox.datasource = yourdata;
combobox.DataValueField = "FieldFromYourDataToReturn";
combobox.DataTextField = "FieldFromYourDataToShow";


To not show an element - you could just remove it like below:
combobox.Items.RemoveAt(combobox.Items.Count-1);
Or you could make sure that it was never selected - which would probably be a better solution.
