DatetimePickerAdv - Editing Over Null Text

[Tom Affholter]

My students and I have been studying the datetimePickerAdv. Is there a way to make it more like the FoxPro/dBase (dbx) date control? My students are working on an app that manages our college’s apprentices. The app they gave us to “upsize” was originally developed in Visual FoxPro. Although I do not think it a major problem, the student’s client does. FoxPro dates are/were entered 020207 = 02/02/2007 or 2/2/07 = 02/02/07. It did not have a calendar sub-control. But FoxPro identified null dates as " / / ". To enter a date you were in edit mode immediately.

With the current control, we enter default null text such as "no date". I can simulate " / / ", but the user cannot edit directly without some programmatic intervention. Can we make it such that the user can type over the null text? We added a hotkey (ENTER) that changed the null to today’s date and positioned the cursor in the first field. Still, the users want the older method.

Any suggestions? If not, this might be a nice future feature.

Thanks,

Tom

Hi Tom,

This could be achieved by setting NullString and NullModeKeyReset property of the DateTimePickerAdv control. NullString property assigns some test representation for null value. NullModeKeyReset property assigns reset key to preset null values. That is it enables us to enter value to the DateTimePickerAdv. One more property CustomFormat enables us to enter date time values as per our wish. AutoForwarding forwards the key to Day, Month and Year fields automatically.

[Code]
this.dateTimePickerAdv1.IsNullDate = true;
this.dateTimePickerAdv1.NullModeKeyReset = Syncfusion.Windows.Forms.Tools.NullModeKeyReset.NumericKeys;
this.dateTimePickerAdv1.NullString = " / /";
this.dateTimePickerAdv1.CustomFormat = "dd/MM/yyyy";
this.dateTimePickerAdv1.AutoForwarding = true;

Please refer to this sample and let me know if it helps you.

Thank you for your interest in Syncfusion products.

The DateTimePicker control is part of a group of ActiveX controls so you should be looking for the Mscomct2.ocx file for users to be able select a date from a drop-down calendar interface. fast essay writing service

I need to find more information about DateTimePicker, because I'm preparing a written work on this topic and I need to do it properly. I want to know your experience and tips about it. I already looked at examples of guys on this topic https://gradesfixer.com/free-essay-examples/religion/ but there are still questions, for me, all this pretty hard!

I'll be very grateful for any recommendations.

I am using  SfDateTimeEdit1 AllowNull. and 

 SfDateTimeEdit1.Value = Nothing

Now when i try to edit the null value... value is not editable.

is there NullModeKeyReset in sfdatetimeedit control..

[Harinath Navaneethakrishnan]

Hi singh,

We are able to edit the datetimeedit value when it is null with NumericKeys using the keyboard. Please refer to the sample and the video from the attachment for your reference.

Currently, there is no support like NullModeKeyReset in DateTimePickerAdv. Could you please elaborate your requirement that you want to meet? based on that we will try to provide a solution with existing API or we will consider it as a feature request.
