Grid binding and add row with csla 2.0.3

figuerres posted on Wednesday, October 18, 2006

Hi, can anyone tell me if the 2.0.3 source has a problem with gridviews?

I found a note and a downbload from 2003 that talks about chnages -- seems like they would be in the 2.0.3 code by now.

I am trying to use the Developer Express XtraGrid to allow users to edit and add rows.

if I add a row in code that row seems to edit ok.

but a GUI attempt at an add fails W/o any error messages.

? anyone know the way to fix this ?

more info:  after reading some posts I am trying a few chnages,

CurrentSale = MCS.FitPro.Library.Invoice.NewInvoice(0, True)
CurrentSale.Invoicelineitem.AllowEdit = True
CurrentSale.Invoicelineitem.AllowNew = True
CurrentSale.Invoicelineitem.AllowRemove = True
CurrentSale.BeginEdit()
CurrentSale.Invoicelineitem.Add(Me.CurrentSale.Invoicelineitem.NewLineItem())Me.InvoiceBindingSource.DataSource = Nothing
Me.InvoicelineitemBindingSource.DataSource = Me.CurrentSale.Invoicelineitem
Me.InvoiceBindingSource.DataSource = CurrentSale

this all runs but now when I start to edit I get an exeption. Here is part of the trace:

System.MissingMethodException was unhandled

I think when I used codesmith I generated
Invoice - EditableRoot
InvoiceLineItems - EditableChildList
InvoiceDetails - EditableChild

does that sound right??

Ok found and fixed!

 

notes:  the Codesmith templates from codeplex download are not adding an override that was needed.  the template has the code, but it's not added.

override CoreAddNew() was missing and the contructor needed .AllowAdd = True
