Question

dateTimepicker选择了日期后，日历没隐藏起来

public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void dtpBirth_ValueChanged(object sender, EventArgs e) { dtpBirth.Format = DateTimePickerFormat.Short; dtpBirth.CustomFormat = null; } private void Form1_Load(object sender, EventArgs e) { dtpBirth.Format = DateTimePickerFormat.Custom; dtpBirth.CustomFormat = " "; }

我选择了日期后，日历不收起来

楼主可以把
dtpBirth.Format = DateTimePickerFormat.Short;
dtpBirth.CustomFormat = null;
写到
dtpBirth_CloseUp（）事件里，我测试过的，可以！
