We are facing the below issues on DateTimePicker
1st issue:
1) Enter the date, month & year.
2) If we highlight the whole date & update any value, year field is getting changed.
We need it to update from month date & year if it is fully highlighted.
2nd issue:
1) Enter the date, month & year.
2) If we click "Tab" it is getting focused on the next date time picker. When we go back to the previous datetimepicker it is focussing on the edited year.
It should focus on month on every datetimepicker.
Note : If datetimepciker is fully highlighted it should update on MM/DD/YYYY. Demo project & video link attached for your reference.

1. I was not able to reproduce this on my side (see attached). When I select the entire date and start editing the month is selected. Do I need to do anything specific in this case?
2. I was able to reproduce that, you can use the following approach for it:
Public Sub Datetimetype1(DName As RadDateTimePicker) 'other code omitted AddHandler RadDateTimePicker1.DateTimePickerElement.TextBoxElement.TextBoxItem.GotFocus, AddressOf GotFocusEnd SubPublic Sub GotFocus(ByVal sender As Object, ByVal e As EventArgs) Dim dtprovider1 As MaskDateTimeProvider = TryCast(Datepickename1.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider) dtprovider1.SelectFirstItem()End SubI am looking forward to your reply.

Please follow the below steps to reproduce the issue.
Issue1 :
Enter the month, date & year and without clicking anywhere please select the datetimepicker value from right to left, and enter the value it will focus on year.
Issue 2:
Thanks it is working fine, on the event which you have given, while running it does not call the autoselectnextpart event. But it should work like without pressing the arrow keys it should go to the next cell.
1. I was able to reproduce that, but, if I comment the SelectedItemChanged event handler the issue does not occur. Would it be possible to explain the purpose of this code and your exact requirement?
2. The AutoSelectNextPart is already set in your code and adding the GotFocus event handler is not breaking this behavior on my side. Perhaps you can attach a new project where this is broken?
I am looking forward to your reply.

Hi Dimitar,
Issue 2:
Thank you for the suggested solution it is working fine.
Issue 1:
The selecteditemchanged event is to stop the AutoSelectNextPart in the year cell. AutoSelectNextPart should be stopped in the year field & should not move further.
We have used a link for implementing it, link mentioned below for your reference.
-> link
Our requirement, if the cell column is fully highlighted (left-right/right-left, double clicked on the datetimepicker) & if we make any changes, it should start editing from month.
You have to handle these cases separately. I have updated the project and I have added MouseDown and KeyDown event handler which are selecting the first item.
I hope this helps. Should you have any other questions, do not hesitate to ask.

Hi Dimitar,
Thanks for the test project. It works but we have a small issue on it. In the test project once we click the datetimepicker it is getting focused on 1st entry (month) but we need an option to select the month/date/year or any of the 2 entries (month & date or date & year).
Please remove the selection option on month & enable an option for selection based on the user click. If the user clicks near to/on year it should focus on year & same applies to others too.
We'll share a video link of old application control for your reference.
The mistake is mine, you should check for the SelectionLength in the MouseUp event handler as well:
Private Sub TextBoxItem_MouseUp(ByVal sender As Object, ByVal e As MouseEventArgs) Dim item = TryCast(sender, RadTextBoxItem) Dim control = TryCast(item.ElementTree.Control, RadDateTimePicker) Dim dtprovider As MaskDateTimeProvider = TryCast(control.DateTimePickerElement.TextBoxElement.Provider, MaskDateTimeProvider) If dtprovider.SelectedItemIndex <> 0 And item.SelectionLength > 4 Then dtprovider.SelectFirstItem() End IfEnd SubPlease let me know if there is something else I can help you with.
