Hi Friends,
I am using the DatePicker
<eo:DatePicker ID="txtDepTime" runat="server" SkinID="time" ></eo:DatePicker>
I want to use it as TimePicker . I able to take the Time from DataBase and display it in the DatePicker put i am not able to insert Time from the Picker back to the DataBase.
My Code where i takes Data From DB to the DatePicker
DatePickerDepTime.SelectedDate =TktLogEnt.DepartureTime;// Fetch Data From DB
My Code to Save it back in DB from DatePicker
TktLogEnt.DepartureTime = DatePickerDepTime.SelectedDate; // Store Data To DB from DatePicker
The Error:
The added or subtracted value results in an un-representable DateTime. Parameter name: value
The DepartureTime in my DB is of DataType DateTime.
And One cannot Enter only Time into this Column as it needs also Date.
That is the I need to Enter or it has to take the Date By Default.
Earlier i was using a normal TextBox From which i was easily able to Fetch and Store Records in this Column, and later i just gave a thought playing with the Datepicker i have and i saw it has for Time also.
Henceforth i am trying to use it as TimePicker also :) But i am stuck.
Any Help would be appreciated.
Thank you
Cheers
Menon

Hi Menon, As for the error message, please post the full stack trace. That will help us to identify where it occurs. In order to use DatePicker to edit time value, you must set PickerFormat to include time elements, as detailed here: http://www.essentialobjects.com/ViewDoc.aspx?t=EO.Web.DatePicker.PickerFormat.htmlThanks

Hi Menon,
Check the date part. When you use our DatePicker to input time, the date part is 1/1/0001 --- the mininum allowed date. So if you leave it empty, SelectedDate would be "1/1/0001". If you enter a time value, for example "1:00", it will be "1/1/0001 1:00".
If you try to subtract time from this value, you may get an error. For example, if the time user entered is "1/1/0001 1:00", and you try to subtract two days from it (new TimeSpan(2, 0, 0, 0, 0)), you will get that error because the minimum possible date is 1/1/0001, and you can not subtract two more days from it.
Mostly when you do not care about the date part, you are probably using today's date. So instead of doing:
DateTime userInput = DatePicker1.SelectedDate;
You might want to use:
DateTime userInput = DateTime.Today + DatePicker1.SelectedDate.TimeOfDay;
Thanks

Dear Admin
Thank you very much, I dont know how to say , but you really Helped me out.
Actully i didnt do
DateTime userInput = DateTime.Today + DatePicker1.SelectedDate.TimeOfDay;
But in my Entity Class i am initializing the Column DepartureTime. I initialized it as DateTime.Today;
And my problem was solved.
Thank you very much once again. EO objects has been the best choice , thats all i can Say :)
Cheers
