I have put the DateTimePicker control on my Form and I have made it's CheckBox property to ture ,
Now I need to know is there any Event which is fired when the Check status of the checkbox in DateTimePicker is Changed.
It looks like there is a bug in the DateTimePicker control, because I don't find any event specific for the changing the check state of the checkbox, only the ValueChanged event seems available. So that event should trigger every time the date in a dtp is changed manualy, or by choosing a date from the calender or when the checkbox in the dtp is checked or unchecked by clicking on it, the event ValueChanged should be triggered. But it doesn't do that all the time.
[Code]...
If DateTimePicker1.Value.Year <= DateTimePicker2.Value.Year Then 'dtp2 = expiry date
If DateTimePicker1.Value.Month <= DateTimePicker2.Value.Month Then
MsgBox("Expiry Date Correct!")
Else
MsgBox("Expiry Date incorrect!")
End If
End If
How would I get it to check the date? Datetimepicker1 is the current date, while Datetimepicker2 is the expiry date.
I am writing a User Control. Into each control I am loading a custom biz object. Because the biz object implements IDataErrorInfo interface I am able to use the ErrorProvider control on the user control.
I am binding the ErrorProvider to the biz object like this:
Me.ErrorProvider1.DataSource=MyBizObject This is all working perfectly EXCEPT. The validation is happening (and therefore I am displaying the blinkey error signs next to all feilds) as soon as the User control is loaded into the host form.
Each biz object implements a SAVE method and I want the validate to not happen until the save event is triggered on the biz object.
When DateTimePicker check state changed,ValueChanged and TextChanged events don't work always.

View 4 RepliesI hope you'll humor me with this, but I can't wrap my brain around it. I am attempting to add a ToolStripControlHost(DateTimePicker) to a MDIParent form, which will be used to call a method which shows the Child form(s). I have no problem with the adding the DateTimePicker, the showing of children, etc., but how to call the method from event(.ValueChanged?) of ToolStripControlHost? Despite much Googling and reading I'm not very clear on the entire event handler code. The following is where I currently am:

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

In Vb.net 2005 how can i trap the checked/unchecked state of a datetimepicker through an event. I'm trying to execute two different methods based on the checked/unchecked state of a datetimepicker when the user clicks the datetimepicker. When the user checks the dtPicker Method A is executed, when the user unchecks it Method B is executed. How can i trap it.

View 6 RepliesI have not been able to find a way to get the datetimepicker with ShowUpDown= True and custome format set to h:m tt to increment in 15 min intervals. I have been able to set it when the form is loaded to the nearest 15 min increment. But I need it to increment in 15 minutes units.
This can be down with the NumericUpDown control, but I need two of them one for the hour and one for the minutes and set it's Increment property to 15. Again I can set it to adjust to correct hour and the nearest 15 min. And of course I have to watch and when I go over 60 reset to zero and increment the hour control.
The users will be burly oil field workers using a Panasonic Tablet PC with a stylus in the field. It seems that it would be easier if I could increment the datetimepicker in 15 intervals.
Basically, I have a form. It has two datetimepickers which both have the format of "dd MMMM yyyy hh:mm:ss"..However, I want to be able to do some calculations with them and return a format of: "ddd dd MMM yyyy HH:mm:ss" with the milliseconds but not sure how to show the milliseconds. And how to do the calculations..A date and time gets entered in the datetimepicker of "18 November 2010 02:59:07"And in the other one the data may be: "20 November 2010 01:59:07"..I want to be able to find the difference between them - including the milliseconds, seconds, minutes, hours, year, month and date. etc..I have looked through the internet however, nothing uses a datetimepicker [code]I currently have this, it returns the number of different fields, but not sure how I can convert this into a readable time/date.

View 1 RepliesIf you enter 11 for instance into the year component of the date then tab off the control the text returned to the validation function is the text before the year was entered rather than the new text.The problem can be overcome by making the control invisible then visible. This has been the case since Visual Studio 2003, it would seem to be a bug.
View 1 RepliesWasn't really sure what to name this thread or how to explain it. I have a form with a dateTimePicker control on, textbox for days, button and label, when the button is pressed I'd like the amount of days put into the textbox to be added to the value in the datetimpicker then the result being put into the label.
E.g. Select 26th November in the DTP, then put 6 into the textbox, press the button then have 2nd December come out in the label. I've tried a few things but all fails and just gives me back the original value in the DTP.
is it possible to set the datetimepicker control's borderstyle = none? 2nd question, how to use 32bit api functions in 64bit vb2010 express beta 2?
View 4 RepliesI am having the following problem, when the user wants to use the DateTimePicker (DTP), the date box shows in the middle of the screen. Then if the user wants to select a date he cant, instead the date box goes away and the DTP value remains unchanged. This is not always happening, sometimes it works fine and sometimes this happens.Please go to the link below for an image (you can see that the DTP control is on the left while the date box is to the right):[URL].. application is being run from a server to a local client on the user machine, I dont know if this has anything to do with it.

View 11 RepliesI am developing with VS2010 VB.Net and a SQL '08 dbase. I have a DateTimePicker control that by default displays the current date. If you ignore the DTP control and accept what the default is and save the record, in the database table, the value for the date is 'NULL'. I delete the record out of the database and re-create the record in the UI, but this time, I click on the DTP control and actually click my mouse on the current date or any date and then save the entry and it saves to the database properly. I guess what I am after is if a user instantiates the UI form to perform data entry and accepts the current date in the DTP control without clicking on the control, the value is saved properly to the database.

The backcolor of a default DateTimePicker control seems to be Color.White, but can this change based on a users theme colours and how do I find out what it is currently set to?(There is no backcolour property and DateTimePicker.DefaultBackColor returns SystemColors.Control which is not actually correct)I guess that if someone can confirm that this can't change then I am safe to hard code it? The basis of this question was not actually a typo, it was the fact that BackColor does not show up in my DateTimePicker control intellisense.
