When I clicked expand button in Hierarchial Grid, only the event of MasterTableView's OnNeedDataSource event is fired but DetailTablesis not expand.
After that I got javascript error as follow：
Uncaught Error: Sys.WebForms.PageRequestManagerServerErrorException: 運算式中語法錯誤。

The JavaScript error indicates that there might be a server error and is hidden by AJAX. To learn more about it and eventually find the underlying issue, please follow the instructions from the Get more descriptive errors by disabling AJAX article.
You can also check out the basic sample I've attached which fires the DetailTableDataBind event every time a row expands.
I hope this will prove helpful.

I tried to set EnableAJAX="false" but I can't find any other new error message.
My Asp.net's structure is MasterPage+ContentPage and RadScriptManager is written in MasterPage as pic
.
I load master grid successfully. If I click expand and there is no record in detail gird's datasource, error didn't occur, but if there are records, an Uncaught Error: Sys.WebForms.PageRequestManagerServerErrorException: 運算式中語法錯誤 occured.

According the error message, AJAX is still enabled on the page.
In order to provide you with a more accurate answer, we would require more information about the scenario. At this point I would advise you to Isolate the problem in a sample project and send it to us attached in a formal Support Ticket for further investigation. To save you some time, you can modify the sample page from my previous reply and attach it to the ticket.
