Hi all,

I am using C#, .NET and I regularly use PropertyGrid control in my project. Ifound difficulty in creating and applying a datemask(dd/mm/yyyy) to the DateTime property item in the propertygrid such a way that, user can enter only in that format. For example, by default "dd/mm/yyyy" should be displayed in the DateTime property field. When user key in numbers, the numbers should replace the respective places in the field dynamically. Ofcourse, user can give input from DateTime picker also.

Please, suggest me withcode snippets or sample source code. Thanks in advance.
Let me know if further information is needed.

Regards,
Kumar

Hi,

Base on my understanding, you want to custom date format for DataTimePicker. You can try it like this:

DateTimePickerFormat.Custom;

"dd/MM/yyyy";

Custom Date and Time Format Strings

If I misunderstood you, or you have other questions, please feelfree to tell me.

Best regards,

Ling Wang

Hi Ling

Thank you for your response. As you know, in general, there are two ways of giving input values to a property item which is of type DateTime.

1) UsingDateTimePicker
2) Entering numbers using keyboard

Here, I am talking about using keyboard. By default, format (e.g., mm/dd/yyyy ) should be displayed in the property item field. When user wants to key in values using keyboard in the DateTime property field in the propertygrid, each key in number should replace the respective letter of the mask at current selection. For example, if user enters 6 at 2^nd position of the month part, m6/dd/yyyyy should be displayed in the field and separators and other letters should remain same in position even user deletes them.

Please, suggest me in the same.

Another question:

For suppose, there are 4 propertygrids and3 list boxes have been placed on a main Form in my solution. How can I get information of the currently active/selected controlwhen the project isrunning and how canI access that control in the code? Please, advise me.

Hi,

Do you mean you want to display the string “mm/dd/yyyy�in the dateTimePicker?

If we set the customFormat follow my last reply, this will restrict dateTimePicker only accept the digit. So we can’t add the string to the dateTimePicker follow this way.

You can use this.ActiveControl to get the current control.
