Databinding and BindingContext

[Alex]

Hi:

How can I binf different datasets to the same bindingcontext of the form?

Regards.

 

[Ilya Tumanov [MS]]

BindingManagerBase classes for both DataSet's will be in same BindingContext
collection on the form; you don't have to do anything.

Did you mean something different? Please clarify what you're trying to
achieve.



Best regards,

Ilya

I have following code, for example:

Public Class FrmClientes

Private oBMBDel As BindingManagerBase
Private oBMBDel As BindingManagerBase

Private Sub MiDataBinding()

Dim dtFmacli As DataTable = dsFmacli.Tables("Fmacli")
Dim dtFmainc As DataTable = dsFmainc.Tables("Fmainc")


txtNombre.DataBindings.Add("Text", dtFmacli, "nombre")
txtDomicilio.DataBindings.Add("Text", dtFmainc, "domicilio")

oBMB = Me.BindingContext(dtFmacli)
oBMBDel = Me.BindingContext(dtFmainc)

End Sub

End Class

Main table of the form is "Fmacli". My problem is that BindingManagerBase
oBMB doesn't works correctly,

Please be more specific. How exactly it "does not work correctly"? How does
it work?

I would say in this case you should get two completely unrelated bindings.
Is that not the case?

For example, when I try to change position of BindingManager, value for
oBMB.Position is always zero.
For example, when I do: oBMB.Position = oBMB.count - 1

Can it influence that primary key that I define are composed by 2 or 3
fields for each table ?

 

[Ilya Tumanov [MS]]

NETCF V1 does not support related bindings at all, so it's unaware of
primary key existence.

That would be two completely unrelated bindings.



On NETCF V2 you can bind to relations as you would on desktop.



As to position, what's the value of oBMB.count?
