扶醉桌前 提交于 2020-01-14 13:44:06

不想你离开。 提交于 2020-01-14 10:36:09
问题 I use a DateTimePicker on a WPF application. I would like to bind the .Text property to the SelectedDate, so I use binding like this: <DatePicker x:Name="DateTimePicker_Date" Text="{Binding dDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, TargetNullValue='', ValidatesOnDataErrors=True}" TabIndex="3" Grid.Column="1" /> My problem is I use an European culture, so: DAY/MONTH/YEAR instead of MONTH/DAY/YEAR, so if I input : 14/02/2013 , I have a validation error ! How can I solve this? 回答1
