When trying to view columns for any band besides Invoice, I get the attached error. We are using NHibernate for our business objects and the child bands (Detail, NonStockItems, DistributedApproval) are HasMany collections of the Invoice object.
Any thoughts?
Here's the text of the exception:

Hi,
I took a look at the source code for the designer where the error is occurring and it looks like this code was changed very recently to use a BeginInvoke instead of calling the code directly.
But the code here is calling BeginInvoke on the control itself, so if you are at the point where you are clicking on the control, it's handle has to have been created. So the error message you are getting here does not seem possible. And I am unable to reproduce this behavior.
Can you describe exactly when this error message occurs? Is there some specific series of steps you have to follow to get this to happen?
Here's a simple example. I created a new project, referenced my business objects, added a grid and bound the grid to the invoice object. If you go into the "Bands and Columns" portion of the grid designer, expand the "Detail" band and click columns, the error will occur.
I tried opening your sample project, but I cannot open the form because your project is referencing some assemblies that I don't have.
I can't see how this error could be caused by the data source, though. The Stack trace shows you are getting an exception because the handle of the control you just clicked on doesn't have a handle, yet, which does not seem possible. The DataSource doesn't even enter into it, unless maybe your DataSource is somehow causing some kind of interference in the controls on the designer dialog.
Are you able to reproduce the same error if you bind the grid to, for example, an UltraDataSource component with the same structure as the NHibernate data source you are using?
I have encountered a similar problem (although I am not using NHibernate).
I am attaching a simple project that demonstrates the problem.
Here's what I do to make it happen:
1. Open the form that contain the grid.
2. Click on the grid's Start button, to open the designer.
3. Expand the "Band and Column" settings for the first band ('PrintLayout').
4. Expand the second band ('Records').
5. Click on "Columns", under the band - the exception occurs.
Hi Mikel,
Thanks for the sample. I tried it out and I get the same results. I am going to forward this over to Infragistics Developer Support so they can create a case for you and write this issue up for developer review.
