Eliminate null entry in combobox

Question

Is there any property to remove the first (and empty) item in a combobox with style DropDownList ? In other words, I would like to choose the default selected item for a combobox.

I know i can validate the selected item with code, but i want to avoid showing message boxes to the user.

Answer 1

将comboBox.SelectedIndex属性设置为0以将选择设置为组合框中的第一个项目。

Answer 2

You should set the Text or SelectedIndex or SelectedValue property. In this way the combobox updates the text that's is showing and removes the first empty item (that actually is not a real item).
