Your object isn't implementing a DataPortal_Create method.oneinone replied on Tuesday, January 27, 2009
hi,
I have created Dataportal_Create method also,
but still im getting the same problem.
[RunLocal()]
protected override void DataPortal_Create()
{
_id = Guid.NewGuid();
ValidationRules.CheckRules();
}
pls help me
esteban404 replied on Wednesday, January 28, 2009
Try this method signature:
[RunLocal()]
private void DataPortal_Create()
{
_id = Guid.NewGuid();
ValidationRules.CheckRules();
}
If you need to pass in criteria, then embed the criteria class and use this type:
[RunLocal()]
private void DataPortal_Create(Criteria criteria)
{
_id = criteria.ID;
ValidationRules.CheckRules();
}
Step throught the creation and you'll see the failure happen when the method getter tries to find the Create method in your object and can't.
