Thanks Niven.

The grid really needs to have a LayoutSet or GridTable property controlling whether to automatically remove hidden columns from the GrouppedColumns and FilteredColumns collections.

I cannot go back and re-query the database based on the user using the filter row.  Additionally, I can't obviously group in SQL and then display a hidden column groupped in the grid with this issue.

I have attached your sample, but built it as a Web Application Project connected to an IIS virtual directory (not the ASP.NET Dev Server).  I am using Windows 7 running IIS 7, which may make the difference.  The attached sample runs through the VS Development Server, but not IIS, which leads me to believe its either an IIS 7 issue or a strict permission issue between NETWORK SERVICE and my local account.

Steps to reproduce:

1. Copy sample somewhere
2. Create virtual directory in IIS for sample
3. Run sample (either through VS or standalone) after modifying the virtual directory you use (mine is located at http://localhost/TestChartingPrj).
4. View chart
5. Drag OrderID column into Data series
6. Change chart type to Basic 3D Pie or any other 3D chart.
7. You should see the grid error window with the DLL error.

Looking in .NET Reflector, the ISNET.WebGrid.ISChartEngine does have dependencies/references to 2 Xceed DLLs (GraphicsCore and Utilities).

Well, the sample works to show 3d charts somehow.  I've been looking for differences between the sample and my project and I'm not seeing any so far.  I know the sample is using the WebSiteProject and mine is the Web Application Project style in Visual Studio, but both have the WebGrid/Chart DLLs in the bin folder.  They seem to have the same DLL versions (but different file dates 7/22 in the sample and 7/26 in my DLLs).

I debugged both applications, I see the assembly binding call that's different, but don't know why its different.

Sample App:

A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll
A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll
A first chance exception of type 'System.Web.HttpException' occurred in System.Web.dll

No binding after the Graphics2D to the GraphicsGL in my application.  I see the DLL is being stored (dynamically copied) into 'C:\Users\miked\AppData\Local\Temp\{85c02c6d-73d3-438c-a622-6f46d42eec70}" which is strange.

I'm wondering if its a permission issue because the sample is running under WebDev.WebServer.EXE and is running under my credentials as Full Trust.  But my application is running through IIS under the NETWORK SERVICE credentials, which isn't Full Trust.

Any ideas?

Mike

Yup, that's what I figured.  I have submitted this in Developer Network, Product Feedback as a feature request (aka. the black hole :-)   Hopefully it will get reviewed and resolved along with the other requests I need from there.

Thanks,

Mike

Any update on the fix for this?
