CellValueType set to string for expression columns

I have been struggling to format the cells in the expression field of my grouping grid, but the Format property doesnt seem to work. On further investigation, i found out that the cell value types for those columns is set to System.String. I am trying to set it back to typeof(decimal), but this doesnt seem to work. Can someone please post a workaround! thanks

Faraz, the following ctor initializes a new expression field with a name, expression, and result type. The result type will then be picked up by style.CellValueType and your style.Format should work then. public ExpressionFieldDescriptor( string name, string expression, Type resultType ); Parameters: name - The name of the field. expression - The expression. See the Grid User''s Guide for expression syntax and examples. resultType - The result type.
