I will install the next version and will let you know how it goes.

Thank you.

Would it be possible for you to load the 1.7.0.7? Depending on what is going on in your code, this issue may already be resolved.

I am using the 1.7.0.6 version.

Ruchika,

What version of StrataFrame are you using? Have you downloaded the most recent updates? This could play a factor as well.

Can you reproduce this in a sample and attatch it to a post? The only thing I could see as being an issue here is if either the bo translation isn't set up properly (i.e. not pointing to a valid BO), or the control itself isn't bound properly. Past that, we'll need to trace through it and see where it is coming from.

Error description:

I am getting this exception when i hit the form close. And the error happens in a user control dispose method.The user control has bo translation on it and if i remove the bo transaltions i do not get this error.

Any ideas..

Thanks.
