I've created an application that uses WebGrid and the IsDataSource. So far everything works properly, the grid fills in with data, and I am able to edit a text field, and it updates properly.
I wanted to add a web service to the application, however by simply adding a blank file into the App_Code directory, called "myservice.vb", the Update on the WebGrid no longer works. It gives an error:
"ISDataSource ... could not find a non-generic method 'Update' that has parameters ... "
When I delete the "myservice.vb" file, the update functionality works again. This file is not referenced anywhere in the project, and I have also tried with the file there when it has proper webservice functions inside of it, but still get the error.
Is there anyway around this issue?
I don't know what the issue is exactly, but I found a work around that I am happy to use. While reading about the App_Code folder (http://msdn.microsoft.com/en-us/library/t990ks23.aspx), I tried their suggestion and made sub folders, one for my webservice, and one for the datasets. Putting the webservice in a seperate folder seems to have stopped the issue, and allows the update command to work again.
I followed the steps to repro your issue based on your information carefully, but I was unable to replicate it in my end. I also found that this issue is not replicable using WebGridSamples project, start > All Programs > Intersoft WebUI Studio 2009 R1 SP1 > WebUI Studio for ASP.NET > WebGrid7 > VB Sample (Visual Studio 2008 Solution). There is a web service inside the App_Code folder of the project.
Do you have a running simple sample that repro the issue?If you do, could you please send us the sample so that we can investigate it further?
