Hi Martin,
We don't have direct option to set the cell number format. However, it can be possible by using the .NET string format to set the format. Please refers to the below code for number format and for the cell alignment in Grid Model:
//Set the Right to left property for the cell
cell.Value = String.Format("{0:n2}",10.124322);
cell.Properties.Alignment = TextAlignment.Center;
//cell.Properties.VerticalAlignment = LineAlignment.Top;
Please refers to the below sample which illustrate above said feature:
