Hi,

I am facing problem after upgrade 1.6.1. Now, whenever I click new button, I will hit error below even though I have set AllowNullValueOnNewRow = false. Before this, everything just working fine. Any ideas?



System.InvalidCastException was unhandled by user code

Message="Specified cast is not valid."

Source="InventoryBusinessObject"

StackTrace:

at JK.Inventory.Product.BusinessObject.ItemsBO.get_Recalled() in F:\Projects\Inventory\InventoryBusinessObject\Product\ItemsBO.Designer.cs:line 980

at JK.Inventory.Product.BusinessObject.ItemsBO.Field_Recalled_Descriptor.GetValue(Object component) in F:\Projects\Inventory\InventoryBusinessObject\Product\ItemsBO.Designer.cs:line 2545

at System.Windows.Forms.BindToObject.GetValue()

at System.Windows.Forms.Binding.PushData(Boolean force)

I tried to restore back those DLL, but it will crash VS, cause I am unable to open my project.



Please advice. URGENT!!!

Hi,

Just to add on, 1.6.1 mentioned is refering to assemblies posted in forum as patch.



Thank you

1) Are you explicitly setting the value of the Recalled field to DBNull.Value in the SetDefaultValues()?

2) Are any of the other fields in the new row DBNull.Value also, or just the Recalled field?

3) Is it trying to cast a DBNull.Value to a Boolean, or something else?

Hi,



1) Are you explicitly setting the value of the Recalled field to DBNull.Value in the SetDefaultValues()?



No, I doesn't set DBNull.Value to recalled field. Beside, the error occurred BEFORE SetDefaultValues event fired.



2) Are any of the other fields in the new row DBNull.Value also, or just the Recalled field?



It happen to ALL fields.



3) Is it trying to cast a DBNull.Value to a Boolean, or something else?



To Boolean. The same problem happen to other fields as well, which is integer.



Please advice. It is urgent.



Thank you

Is there more to the stack trace, or is what you posted in the first post all of it?  I'm wondering if we could get back to what is causing the binding to update immediately after you add the new row... the binding shouldn't be updating until after all of the values are initialized and the SetDefaultValues() is called.

I checked my code again, and found that as you suspected it might be caused by data binding. It works fine If I just





In my project, the error happen at least two fields which :-



1. Bind to SF's check box

2. Custom lookup control inherited from DevExpress lookupedit.



How should I check next?

Hi.

Just curious, any ideas why didn't the error happen in prior version? Anything changed?

Hi,

Any possible to get the full source code for 1.6.1 (as posted at forum) so that I could debug?



You helps are much appreciated.



Thank you

Hi,

I have successfully reverted back all SF assemblies. And now my application is working fine. So, I am sure something goes wrong with the latest 1.6.1 as posted at forum. Either my mistake or SF source code bug. How could I clarify this?
