We have a page with search form, which uses 2 RadDatePicker components.
and a piece of javascript code :
Default values are set by C# code directly. In general it works fine, but the problem is, that we get errors from calendar components like this -

and a piece of javascript code :

Default values are set by C# code directly. In general it works fine, but the problem is, that we get errors from calendar components like this -
User Agent: Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)

at System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad)
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
These errors come from unknown user and we have no clue, how to reproduce and how to fix it. We use the version RadControls for ASP.NET AJAX Q3 2011. Do you have any ideas, why this can happen?
Best regards,
Leonid
Was this ever resolved? I'm getting the same error in 2024, using the current latest version. The issue seems impossible to replicate, but when users experience it, they get it repeatedly... The page does contain several Telerik datetime pickers but from what i can tell of the form postback data, none actually contained any values. As best i can tell the user did a search on a last name via a textbox. This filtered the results displayed on a radgrid, and then the user clicked one of the rows in the rad grid and got the error.

Hello Mark,
I tried replicating the behavior but as you said the issue is quite hard to replicate based on the given information. If you happen to replicate it on a runnable sample project and send it for further investigations or share the steps to replicate it, please share the information.
Regards,
Vasko
