Infragistics date picker no edits and no nulls

2 New Member
Hi Friends,

Iam new to this forums. by the suggestion of my friend i came to know that this forum is very very good and we get a very good responses. iam new to .NET 3.5 , WPF, infragistics and MVVM.



I have two calender controls and button control ( when clicking the button user see a list of events between the date range. We follow MVVM pattern

1. Start Date(Date Picker) 2. End date(Date Picker) 3. search button

Hi Friends, I have a question on picker validation.

I have done all validation for the date controls except for the following two:

1. when editing the date picker (manually with out using calender and typing the date) the change event is never recognized in View Model

2. Date picker is not allowing null values ( i need my one my date picker to be empty in page load).

I appreciate your answer.


thanks
Divya

Hi. I have a date time picker in my program which uses ADO to read from an Access database. It works perfectly, unless the database is empty (no records) when opened.

Hi, I generate a report using two dates (From and To). I notice if I enter 01/10/2003 that it is interpreted by Access as 10/01/2003 i.e 10th January rather than 1st October as I intended. This is the old problem of US date format mm/dd/yy versus dd/mm/yy. I am stepping through the code and the dates do seem to be ok but when the report runs I get records earlier than 1st October which is not what I want.

Is there a way to say "hey i don't want a...

Hi Guys I have two DateTime pickers one shows the Date and the other the time, this is a requirement of the solution. The problem I have is that when the time is saved to the sql database into a datetime field it uses the default date which is a problem when I try to sort, what I wanted to know is there a way for me to set the date in the time picker to the date in the date picker? Any help greatly appreciated.

Hi, I want to create an asp.net page with a tabpage. On the tabpage I want to use the WebDateChooser and WebDataInput controls of Infragistics. These 2 controls use a mask to enter a date and bankaccountnummber, so that no invalid date or bankaccountnumber can be inputted. I started out with the tabcontrol of infragistics. But I also want to use the atlas update panel, and this gives conflicts when used together with the infragistics...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
