Getting OnLoaded to Fire

Post by larrydhunt » Wed 18 Feb 2009 16:10

I have a question about the partial OnLoaded method. I am using the sample project:
C:\Program Files\Devart\dotConnect\Linq\Samples\MySQL\VBasicLinqDemo.sln

OnLoaded fires when a DataGridView is used, i.e.:
C:\Program Files\Devart\dotConnect\Linq\Samples\MySQL\VB\Queries\MainForm.vb

Code: Select all

dataGridView.DataSource = query.Query
However, if I try to convert a query to an Array the OnLoaded doesn't fire.

Code: Select all

crmDataContext = New CrmDataContext.CrmDataContext(connectionString)
Dim query = From Company In crmDataContext.Companies Select Company.CompanyID, Company.City
Dim anArray As Array = query.ToArray
What do I need to do to get OnLoaded to fire? Note; I think this also happens with MS LINQ to SQL.

The problem is that you are loading only a subset of Company properties, not the Company object itself. No method should fire in this situation.
