DataMember property 'ContractID' cannot be found on the DataSource

Hi,

I get above error when I use the find function on a bindingsource control.
The datasource member of the bindingsource is another bindingsource
control, where the datamember is a relational member of the datasource

The field I'm searching on is absolut in the table behind, I can browse to
it when I debug the bindingsource via the current member.

When I use the table directly on me bindingsource component, it is working
fine. So, only when I bind it to a relational component of another
bindngsource, it doesn't work.

What could be wrong?
Thanks
Bart
 
Hi Bart,

From your description, I understand that you're setting a BindingSource
object as the DataSource of another BindingSource object, like

BindingSource1.DataSource = BindingSource2;

If there is any misunderstanding, please point me out.

The DataMember property is a member of the DataSource object itself. It has
to be a list(or row) in the DataSource. Now the DataSource is the
BindingSource2 object. The object itself does NOT have a property named
"'ContractID". In this case, we cannot do it like this. Instead, you can
try the following:

BindingSource1.DataSource = BindingSource2.DataSource;
BindingSource1.DataMember = "ContractID";

HTH.

HI Kevin,

This is my bindingsource snipped:
'bsContract
'
Me.bsContract.AllowNew = True
Me.bsContract.DataMember = "FK_Contracts_Customers"
Me.bsContract.DataSource = Me.bsCustomer

where 'FK_Contracts_Customers' is the relation between Customers and
Contracts and also exist in the bsCustomers databidingsource..
The bsContract bidingsource is behaving normal, I can browse the records
etc, except the find is not working on my fields in the table 'Contracts'
 
Hi Bart,

To make the Find method work in this case, you have to change the code to
the following:

'bsContract
'
Me.bsContract.AllowNew = True
Me.bsContract.DataSource = Me.fkContactsCustomersBindingSource

fkContactsCustomersBindingSource is an auto generated binding source in
your form that you can use and Contact ID is a part of its properties.

Please try it and let me know the result.

Hi Bart,

Although you can see the DataRows, they are not a part of the
BindingSource's properties. You have to get the relationed BindingSource
first and then get its properties.
