.NET Exception during Deserialization on Postback with RadDatePicker

[Laku]

Hello,

We are getting the following error on a page where we have a RadDatePicker on the form during postback. I am wondering if this has something to do with differences in locale between the user and the browser but am not sure. Has anyone encountered this before?

Thanks,
Eric

Hi Eric,

I'm afraid that I'm unable to recreate the behavior you have described locally. Can you please provide some more details about your RadDatePicker declaration, page setup etc?

Hello,

It appears that this is happening when the client is accessing the site and their time zone is set to a value that is ahead of the clock of the server. For instance our servers are set to -6 GMT, but the client that was accessing the site was set to +5 GMT. If we set the client to -6 GMT the problem seems to go away. Do you have any suggestions?

Thanks,
Eric

Hello Eric,

Unfortunately I'm still unable to reproduce the described behavior locally. I have attached a simple test page, please take a look and let us know if I'm missing something obvious. You may consider sending us (attached to a formal ticket) a small runnable application in which the behavior can be observed.

Best wishes,
Rosen

Hello,

Thanks for your help we have found the issue. In our code we were setting the MaxDate and MinDate properties to DateTime.MaxDate and DateTime.MinDate, which I guess was causing it to overflow if the client was on a different timezone that was ahead of us on postback.

Thanks,
Eric
