Hi all,



I am having a problem using the GridView component and the WebBusinessBindingSource. When I click update or cancel on the grid, I get the message: The business object 'Customers' could not be found on this page.





[InvalidOperationException: The business object 'Customers' could not be found on this page.]

To work from a common ground I have simply taken the C# Web Sample code, added a page (StrataFrame Web Form), dragged on a WebBusinessBindingSource, bound it to the Customers business object, dragged on a grid and bound the grid to the WebBusinessBindingSource. When running the app, if I click the edit on a row and then click either update or cancel, I get the above exception.



There must be something amazingly simple that I am missing here ...



Please will someone point me in the right direction to resolve this.



Many thanks.

Gavin,

Have you downloaded this C# sample (http://forum.strataframe.net/FindPost12344.aspx)?  Because I have run this sample over and over again and it is working just fine.  So first, download this sample, open the solution and press Ctrl+F5.  The sample should run and you should be able to go to the Customers Grid without issue.  If this doesn't work, then there is something else in the mix here.

Hi there,



Yes I have downloaded the sample - the updated version that includes the WebBindingSource.aspx page. I run the sample, click edit against a record, and then cancel and get my favourite message:
