I need help in including the plus and minus operators in row rendering.
Please see my below which is throwing an error
// Row Rendered event
public void Row_Rendered() {
//VarDump(<FieldName>); // View field properties
ShortPayment.EditCustomAttributes = "readonly=\"readonly\"";
InvoiceTotal.EditCustomAttributes = "readonly=\"readonly\"";
InvoiceTotal.EditValue = "ExtendedAmount + TaxAmount";
ShortPayment.EditValue = "InvoiceTotal - PaymentAmount";
}
InvoiceTotal, ShortPayment, ExtendedAmount, TaxAmount are all existing fields in the table
