problem with setting up multiple grid application

I am building an app with numerous GridControls. Each is initialized with:

GridFormulaEngine engine = ((GridFormulaCellModel)gridName.Model.CellModels["FormulaCell"]).Engine;
engine.FormulaCopyFlags |= GridFormulaCopyFlags.ClipBoardText;
engine.FormulaCopyFlags |= GridFormulaCopyFlags.ClipBoardFormula;
engine.FormulaCopyFlags |= GridFormulaCopyFlags.InsDelRangeReferencesUpdated;
engine.FormulaCopyFlags |= GridFormulaCopyFlags.ClipBoardReferencesAdjusted;
engine.FormulaCopyFlags |= GridFormulaCopyFlags.NamedRangeReferencesUpdated;

Everything works fine with cut/paste and calculation/formula support working as long as I am operating within each grid separately. However, as soon as I add the lines:

int sheetFamilyID = GridFormulaEngine.CreateSheetFamilyID();
GridFormulaEngine.RegisterGridAsSheet("grid1", grid1.Model, sheetFamilyID);
GridFormulaEngine.RegisterGridAsSheet("grid2", grid2.Model, sheetFamilyID);

The program crashes with the following message:

"Object reference not set to an instance of an object."

in the line:

engine.FormulaCopyFlags |= GridFormulaCopyFlags.ClipBoardText;

for one of the grids.

Has anyone run into this problem and know how I can fix it?

I stripped the app down to a single grid and no functionality. I started testing at each step of development. Occurence of the "object reference not set to an instance of an object" error begins as soon as I change the value of the CellType parameter for the Standard Cells in the BaseStylesMap from "TextBox" to "FormulaCell". Is this a bug in Syncfusion's libraries? For those using new versions, I am using version 8.2.0.18 of the libraries.

Hi Jan,

Thank you for your interest in Syncfusion products.

I am afraid that I was not able to reproduce the issue. Could you please share us simple sample to demonstrate the issue so that we could sort out the cause of the issue and provide you a solution?

Appreciate any additional information.

Regards,
Asarudheen.
