在组合框中默认的文本 [英] Default text in combobox

问题描述

我有2个组合框，如图像，并想知道是否可以设置一些文本字段的组合框（所以第一个框将陈述成员）。这样，我想摆脱组合框上面的文本框。

I have 2 comboboxes like on the image and would like to know if it is possible to set some kind of text field for the combobox (so the first box would state Members). This way I would like to get rid of the textboxes above the comboboxes.

我知道这可以通过添加成员的数据集，但我DONOT想这样做来完成。有另一种方式？

I know this can be done by adding the "Members" to the dataset but I donøt want to do that. Is there another way?
