Data binding using Strataframe Business Layer

Hi Kingsley.

Yep, I hit the same limitations as you did. So far, I haven’t used the BindingSource for the grids and I usually get the row PK and fill another BO instance with the grid current row, and from then on I do whatever has to be done.

And you are right, we can take advantage of all the other business layer features. In my case I am doing a migration to the web and I have loads of BOs and their rules, etc., which are ready to go. I also use the Security feature completely, will also create the UI for it later. Not to mention the BOM and DDT.

On maintenance forms, I have migrated the SF MaintenanceToolStrip and am able to take advantage of all BO events and methods.

So far its been saving a lot of time for the whole process.

Cheers.

Hi Ivan

Thanks for the response.

I had got as far as using myBO.CurrentView with WiseJ BindingSource for a DataGridView and BindingNavigator

Me.BindingSource1.DataSource() = myBO.CurrentView
DataGridView1.DataSource = BindingSource1
bnav1.BindingSource = BindingSource1

Trouble is (as expected) I cannot bind to custom fields defined in the business object when we use CurrentView or CurrentDataTable. Also the BO.Move/Navigate methods don’t affect the grid current row. But you can handle BO nav events to do this.

And it looks like I’ll need to wire-up CRUD operations from the grid to the BO

So I guess it half works. We can still use the data access part of the SF BusinessLayer, BO.Fills etc (which saves a lot of ADO.NET data access plumbing) and code that was working with BOs,  but binding to controls looks like it has limitations. Still looks like its worth migrating SF BOs to WiseJ web app though.

By the way, as for a Wisej DataGridView I have done it just setting the CurrentView to it.

this.myDGV.DataSource = this.myBO.CurrentView;

Hi Kingsley.

I have been binding SF Business Objects to Wisej DevExpress DataGrids Extensions using the AsEnumerable from DataTable.
It looks like this:

this.myDataGridView.Options.dataSource = this.myBO.CurrentDataTable.AsEnumerable();

Hope it helps.
