I made a simple test using WebGrid 7 in VS 2010 by simply create an empty C# WebSite and set the test site to use .NET Framework 4. After the project is created, I add a page and followed by drag-dropping WebGrid from VS 2010 toolbox to the form page.

An unbound hierarchical WebGrid is added into the page. And after everything is set up, the page is viewed in IE 8 browser and found that everything work smoothly and the grid page was accessed without any issues.

The test uses WebGrid 7.0 build 403. From the test result, I’m sure that WebGrid 7 is compatible with Microsoft .NET Framework 4.

Hope this helps.

PS: I haven’t finished the test uses WebGrid 6. I will need more time to configure my local test for WebGrid 6. I’ll give you the reports as soon as I finish configure my local test-pc.
