Trouble with DateTimePickerExt

[Kenneth Johnson]

I'm not having much luck getting help from Syncfusion with the DateTimePickerExt control. Is anyone else out there using it? Have you figured out a way to initialize the date value to null? I'm also having problems with the CloseUp event. Anyone using it?

Hi Ken,

For question 1, you should use

this.dateTimePickerExt1.IsNullDate = true;

For 2, can you send a snippet that illustrates what you are doing?

Thanks,

I've already tried this:

this.IsNullDate = true;
this.Value = System.DateTime.Parse("1/1/1753");
this.NullString = "";

This was suggested by Clay yesterday morning. It didn't work.

For number 2, all I'm doing is using the designer to create an event handler for the CloseUp event, putting a break point on a line inside, and running my app in debug. The app does not stop after selecting a date from the calender like it does in the MS DateTimePicker.

Ken,

For 1, lines 2 and 3 are not required. It should just be

this.dateTimePickerExt1.IsNullDate = true;

What version of the product are you using? Do you have the latest service pack?

Thanks,
Daniel

When I set IsNullDate=true, the text box is initialized with 10/25/2002. I found in your source code where value is being set to this date. The IsNullDate property does not appear to be affecting the initial value.

When I look at the properties of the reference in my project, the version is listed as 1.5.1.1.

Hi Ken,

WRT problem 1, I can see the problem. It only happens when the value is changed from the default. I have logged a high priority bug report. It should be fixed later today.

Thanks,

OK.

Any thoughts regarding the CloseUp event?

Ken,
The current version is 1.5.1.6. With version 1.5.1.3 we completely rewrote the DateTimePickerExt (external interface remains the same) to overcome some restrictions of the common control (the common control is restricted to displaying dates in the culture of the thread etc). We will have a service pack version available as soon as problem 1 is fixed. With the new version you should not experience problem 2) either.

Thanks,
Daniel

Hi Ken,
Service pack 1.5.2.0 is now available. It can be downloaded using the Direct-Trac interface.

Hi Ankur,

In the DateTimePickerAdv, the Value has to be reset (right click on the Value field in the property grid and check Reset) in the designer before setting the IsNullDate property to true. If not, IsNullDate gets reset to false. Please try this and let me know if you need further assistance. Note that you need to have Essential Suite v1.6.1.8 or higher for this. Thanks for choosing Syncfusion products.

I am using version 1.6.1.8 but DateTimePickerExt control not DateTimePickerAdv. I tried resetting the value property but it didn''t do anything.

Hi Ankur, The DateTimePickerExt control was renamed as DateTimePickerAdv in the v2.0 releases according to the v2.0 naming convention. I have attached a sample_application created using v1.6 which shows how a null value can be assigned to a DateTimePickerExt. Please refer to it and let me know if you need further assistance.
