dateTimePicker控件怎么赋空值
展开全部
初始化时：
this.dateTimePicker1.Format=DateTimePickerFormat.Custom;
his.dateTimePicker1.CustomFormat=" ";事件里写： private void dateTimePicker1_ValueChanged(object sender, System.EventArgs e)
{
this.dateTimePicker1.Format=DateTimePickerFormat.Long;
this.dateTimePicker1.CustomFormat=null; }
已测试
this.dateTimePicker1.Format=DateTimePickerFormat.Custom;
his.dateTimePicker1.CustomFormat=" ";事件里写： private void dateTimePicker1_ValueChanged(object sender, System.EventArgs e)
{
this.dateTimePicker1.Format=DateTimePickerFormat.Long;
this.dateTimePicker1.CustomFormat=null; }
