Tony,
>What I have encountered is that I (having come from the DataSet world) have added my BizObjs - generated nicely by the BLG - to the solution's DataSources. When I place a control on my UserControl - say, mmTextBox - and attempt to set the 'BindingSource' property, nothing appears in the dialog. I imagine that is because my BizObjs of interest are not registered with that UserControl. If I use a non-mm control, setting the "DataSource' property causes Visual Studio to generate a BindingSource for my BizObj and place it in the non-visual designer tray. The BindingSource+BizObj combination, while permitting display of the bound data, does not seem to communicate regarding modifications to that data!
Now that MM .NET 2.4 is released, here is some code from what will be in the next version of MM .NET. For now, try adding this code directly to your project. You should then be able to create user control subclasses of this class that allow you to register business object and bind your user interface controls in the "regular" way:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using OakLeaf.MM.Main.Business;
namespace OakLeaf.MM.Main.Windows.Forms
{
public class mmUserControl : UserControl
{
public virtual mmBaseBusinessObject RegisterBizObj(mmBaseBusinessObject businessObject)
{
if (mmAppBase.IsRunning)
{
mmBusinessBaseForm ParentForm = mmAppDesktop.FormMgr.GetParentBusinessForm(this);
if (ParentForm != null)
{
ParentForm.RegisterBizObj(businessObject);
}
}
return businessObject;
}
public mmUserControl()
{
InitializeComponent();
}
}
}
Here is an example subclass:
public partial class TestUserControl : mmUserControl
{
private Orders oOrder;
public TestUserControl()
{
this.oOrder = (Orders)this.RegisterBizObj(new Orders());
InitializeComponent();
this.oOrder.GetOrderByOrderID(10248);
}
}
