I am working VB.NET 08 Access Database. I have Two "DateTimePicker" controls one is "StartDate" and one is "Enddate". Now I am selecting Startdate like May 1st OK. Now when I select Enddate control this calender shows only Equal or Greater than dates should be Enable. EndDate should be Always Greater than Equal Date.

View 1 Replies1.I want to click the datetimepicker and textbox will display dates by dates,I want to know if I can do this. Example - textbox will display -> 2/10/2010,2/12/2010,2/25/2010.
2. Can I off the today default on the datetimepicker?
When entering a date in the text-part of a datetimepicker, one could find him in deadlocked situations in normal conditions, but even more if min/max dates are set.Explained by example: having format set to mm/dd/yyyy, having date set to 01/31/2010, wanting to change it to 02/28/2010.At this point the '02' for the month isn't accepted because the day is set to 31, not existing in month 02.
When min- or maxdates are set, the situations where fluid date-entering is even more difficult, are even more frequent.To keep some compatibllity, a new property named 'partialvalidation' which defaults to 'True' could make that when set to 'False' a date is only validating/validated when the control loses focus or any other event (EndCurrentEdit, ...).
I have a dateTimePicker and I set the maxdate to today's date Now when a user select the date after today's date it won't select it but it still be displayed. How can I remove them or disable them do the users can't even click on the date if it is after today's date

Does anyone know what is the best way to check has datetimepicker been clicked and value selected before saving and updating database. I am working on a database app and database field for "Date" does not allow null so in order for app to work properly i would like before saving to check if the date is selected and if not to create warning for user. I have created that for "Name" and other columns, but those are text boxes so I had no problem with that. I could change the database field for "Date" to allow null, but that the easyer way and not what I really want. If someone has solution for problem
