Need to use DateTimeEditor with empty date enabled in property grid

[Steve McWilliams]

I have a date field that can be null. I don't want to show 1/1/0001 as the default date.

Default widget for DateTime property is DateTimeEditor without the No date option.

Default for DateTime? type is just a text box.

How can I connect a nullable DateTime property with a DateTimeEditor having IsEmptyDateEnabled = true ?

Hi Steve,

We have checked your reported query and it can be achieved by using the Custom Editor in the PropertyGrid. In order to display the null value in the DateTimeEdit, we need to set the properties IsEmptyDateEnabled, NoneDateText, ShowMaskOnNullValue and the type of DateTime should be nullable. We have prepared a sample for the same and it can be downloaded from the following location.

Please check with the above sample and let us know whether it meets your requirement.

Thanks. I got this to work for the DateTime properties.

I also realized I need to do the same thing for some nullable int properties.

I followed the DateTime example to try and add a custom editor using IntegerTextBoxEditor for int? property type.

I got as far as getting the box to allow null values, but it's not accepting and storing actual values.

Could you send me an example of similar code I need to construct IntegerTextBox Editor with UseNullOption = true ?

Hi Steve,

Thanks for your update.

In IntegerTextBox, we have maintained Int64? Type for the Value property and since you have set the property as int? type, the value was not updated properly in the sample. We have now modified the sample by adding a CustomEditor for the IntegerTextBox and have set the type as Int64?. Please download the modified sample from the following location.
