Upgrading from 1.1 to 2.0 .net framework

[Maxim Software Systems]

We are in the process of upgrading our current projects from VS2003 to VS2005 and are currently working with v3.3.0.0 of the Syncfusion Grid.

After moving a project to VS2005, the 1.1 .net framework versions of the grid libraries cause "stack imbalance" exceptions. Of course, it makes sense to change the Syncfusion references to the 2.0 .net framework versions, which I did by removing the 1.1 references and replacing them with the 2.0 references.

Unfortunately, we're getting strange exceptions now, like: "Unable to cast object of type 'Syncfusion.Windows.Forms.Grid.GridBaseStyle' to type 'Syncfusion.Windows.Forms.Grid.GridBaseStyle'." during the initialization of a form that has a grid on it (the full exception is at the end of this message).

Is there some special process for switching from the 1.1 to the 2.0 framework versions of the Syncfusion libraries?


--------------------------------

Example error that appears after replacing 1.1 with 2.0 .net framework versions of the grid dlls:

An error occurred while trying to show the Main screen.

Silly me. The project this exception was seen in was using an extended grid class which was defined in another project which was still referencing the 1.1 dlls. I updated that project and the errors all went away.

I may have spoken too soon. Thought the previous exceptions no longer appear, I'm getting the PInvokeStackImbalance errors again now like I was back when all the Syncfusion dlls were the 1.1 .net framework ones.

--------------------

PInvokeStackImbalance was detected
Message: A call to PInvoke function 'Syncfusion.Shared.Base!Syncfusion.Runtime.InteropServices.NativeMethods::ImageList_DrawEx' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.

Upgrading to th 5.102.0.51 version of the Syncfusion Studio appears to have solved all my problems.

I hope this little adventure will be useful to others. :)
