Hi have a RadScheduler related to an objectdatasource. When i do some operation on the Scheduler, like Insert, Edit or Delete, I've notice that the scheduler exec the operation two time. The first time is executed from some "embedded" method and second time is execute from my method of the datasource. Why this happens? There is a way to disable the calling of the "embedded" method???
Thank's
Dan

Could you please send me in a sample project what is this "embedded" method which is called before your method from the datasource? Meanwhile please take a look at our"Car Rental" application for an example of RadScheduler bound to ObjectDataSource.
All the best,

The pasted code is very hard to format and run.
Could you please send me a runnable project so I can inspect it and help you?
Thank you!

As I see your status is "No Active Support" and by default we don't answer to such clients. However I'll make an exception for you. Please attach your code to one of the sites for free online storage and send me the link. For example : http://www.4shared.com/.
I'll do the needful to inspect it and help you.

this is the link where u can download the project :
http://www.4shared.com/file/KX_FMguI/scheduler_ObjectDatasource.html
Into the visual studio project you'll find a readme file where there are the step to reproduce the behaviour.
Thank'you very much for you'r availability

Unfortunately we don't work with MySQL. Can you convert the project to SQL Database and Sql connection and I will try to help you.
Thank you!
