Hi Intersoft,

I have to get the connection strings from database based on the site login and apply retrieved data to ISDatascource which inturn display the events,resources etc in the WebScheduler.

So, i have written the required code in ISDataSource 's Object created event. This complete things works just fine, i mean... i would get the connection strings based on the login id and WebScheduler displays the resorces,events etc perfectly.

But, i am stuck with an unknown exception "Exception has been thrown by target of invocation" while creating an event, creating category etc (basically all insert statements) 

Displaying,deleting all things works as expected...but only insertion is problem.

We have bought the WebUI studio licence and if you want our order id to provide premium support, please let us know. I would provide them seperately to any of your email. Also i have created a sample project with DB script to reproduce this issue which i can share with you too.

Your help is much anticipated...thank you.
