Answer 1

You can either convert the format of your date before you load them to the combo box or run this code after the combobox have been filled:

for (int index = 0; index < this.comboBox1.Items.Count; index++)
        {
            this.comboBox1.Items[index] = DateTime.Parse(this.comboBox1.Items[index].ToString()).ToString("dd-mm-yyyy");
        }

Edited:

If your are using databinding and sure that the type of data being displayed is date. Try this:

 this.comboBox1.FormatString = "dd-MM-yyyy";

如果您接受在应用程序中进行全局更改，则将CultureInfo.CurrentCulture设置为欧洲语言环境。
