[Solved] Issue with datetime picker 2011.1.315 french format not a valid datetime

[Julien]

Hi,

I am using the latest version of DatePicker (2011.1.315) and I've got the error message :
String was not recognized as a valid DateTime
<%= Html.Telerik().DatePickerFor(model => model.DateDebut).ShowButton(true) %>

The culture of my project is set to "fr" culture (with date format as dd/mm/yyyy) and I set Telerik Globalization to true but when I have the day of the date (DateDebut) greater than the 12 of the month I get the error.

Thanks for your help.

Hello Julien,

 
It seems that the server, to which the formatted date is send, cannot parse it. Here is an example which shows that the datepicker works correctly on the client.

Please verify that server can parse date formatted in dd/mm/yyyy.

Hi Georgi Krustev,

You're right, it works fine with a form using post method but I was using a form with get method and converting the string to a DateTime using DateTime.TryParse.
To fix my issue I've created a ModelBinder binding the string to a DateTime using the current culture and It's working fine.

Has this issue been fixed? Or is this always going to happen this way. I am getting the issue posting a date in british format DD MM YYYY, but it is received @ server as US format.

Hi Dean,

Is the date posted correctly if you use Html.TextBox instead of the datepicker? If it doesn't then there may be a problem which is not related to Telerik extensions for asp.net mvc.

Hi

If I set a model with a DateTime theDate and a String theString, and set them both to DateTime.Today in the controller.

Then have a view with 2 Text controls for the ViewModel, they are both shown as 04/07/2011  (correct for UK). If I then use a submit button to do a  HTTPGET , theDate has 07/04/2011 and the theString has 04/07/2011.

I have checked the CurrentCulture and CurrentUICulture, and this happens when both are en-GB.

Hi Dean,

This sounds like a known behavior of the model binder. You can find more info in this blog post.

Thanks, it is not a Telerik problem.

I have tried those suggestions, and it does not completely fix my problem.

Some dates might be a 'Post' and some a 'Get', and this is causing the date to switch from GB to US, and I don't know how to differentiate.
