Version 2.0.7.122 Firebird .net 2.0.1

When I add a user control to another project I get this error.

When I comment this line I can add the usercontrol.

Types.GetMulti(Nothing)

The error when that line is not commented out. I have the app.config in all projects.

An invalid connection string argument has been supplied or a required connection string argument has not been supplied. Hide

Did you use the app.config generated by LLBLGen? Does the project that contains the user control have the same app.config? Are you able to access the database using your project that is having the user control added? This info may help isolate what is causing the issue.

Yes, I haven't set the connection string so I am assuming it is pulling from the app.config. All projects have the same app.config file.

I don't seem to have this problem in the usercontrol project. It is when I add the usercontrol on a form I am getting that error. For some reason the getmulti is what is triggering the error.

I think this is bacause Lazy Loading is automatically triggered.

That is what it was. Thanks.

I can bind it at runtime no problems. It is at design time the error would happen when i tried to use that usercontrol.

Thanks,

Thomas

Hello,

at design time when did this errors come? Did it come only with that usercontrol?

It came when I added the user control to another project form.

I had the getmulti in the load event of the user control with the collection bound to my grid through the designer.
