How to customise the DataGridViewCol umn with a UserContro editingcontrol ?

[Tsair]

I do a customise DataGridColumn with a UserControl (TextBox + Button for
Calender), DataGridView does not show the data content of the column.

Why do you need a TextBox and a Calendar.. when you can just click to show a
calendar, allow the user to change date then...

the existing DateTimePicker input by Day then Month then Year which is not
convineance in keyboard stroke.

I customise the usercontrol with textbox + button to just type in the day
month year, and the button provide the option for popup the Datetimepicker
for selection.

When i include this usercontrol into DataGridView column, the column does
not show the input as user key in, it just blank.

Check out the following MSDN2 article. It illustrates a custom
DataGridViewCol umn control that uses a DateTimePicker:
