RadDatePicker in Radgrid,the calendar didn't popup

[Charles]

I used RadDatePicker in EditItemTemplate of GridTemplateColumn in a Radgrid, following this demo:
http://demos.telerik.com/aspnet-ajax/calendar/examples/datepicker/databinding/defaultcs.aspx

But when page first loading, the calendar didn't popup if I click the button, if I changed the RadSkinManager option, the calendar will display correctly.
Could you please help me find the issue? Thanks.

Hi Charles,

From the provided code it would be hard to pinpoint what is preventing the popup from opening.

Common reason for the popup of RadDatePicker not to open is a JavaScript error on the page. Please ensure that there are no such errors when the page is opened initially.

Also would you try commenting out the RadAjaxManager, RadSkinManager and RadFormDecorator in order to test a more isolated scenario? With what skin is the popup not showing? Would you also try triggering a postback with a button and check if the popup will be shown then?

Hi,
If I comment out the RadAjaxManager, the datepicker can work properly, the calendar would be popup.

Hello Charles,

I tried replicating the issue, however I was unable to. I am sending a sample project, based on the code from your post that I used for testing. The calendar popup is opening as expected on my end. Give it a try and let me know if it is working for you.

In order for us to be able to pinpoint the cause for the described behavior we need to replicate the problem locally. Could you open a support ticket and send a runnable project where the issue is observed? This would allow us to debug the code and look for the cause of the problem.
