Hello

From the posts thus far I assume you are using windows controls and not web controls. The concept I suggest should work for both. I have created the following object for my web apps which gives me access to the web pages methods and objects. It has given me the ability to bind the WebGrid objects using the web pages .BindControl({control}) method.

Changes/Modifications

1. You should change the namespace to something useful for yourself.
2. BusinessWebPage property should be based on your MM form or web page at it's highest level without being specific e.g. mmBusinessForm versus mySalesForm. Replace dcgBusinessWebPage with your object mmBusinessForm.

Of course, when you use UserControls you will not have the kind of access to the data elements because you are not registering the controls on a MM Bindable form or object. You can still assign the data properties manually or programmatically. Using this object allows you complete access to the properties and methods of the form or web page. And it is simple.

Examples of use (Web version):

//get a reference to the business object within the usercontrol
//assign it to a UserControl property for future use
//any properties on the retrieved object are the same as if they were on the webform itself
this._Waiting = (Waiting) this.BusinessWebPage.GetBizObj("Waiting");

//Bind the grid control using the MM version of binding
//The BindControl method is only available on the mmBusinessWebPage
this.BusinessWebPage.BindControl(this.grdWaiting);

using System.ComponentModel;
using System.Web;
using System.Web.UI;

using DCG.Main.Web.UI.Containers;

namespace DCG.Main.Web.UI.Containers
{
	/// <summary>

		public dcgBusinessWebPage BusinessWebPage
		{
			get
			{
				return this._BusinessWebPage;
			}

			set
			{
				this._BusinessWebPage = value;
			}
		}
		protected dcgBusinessWebPage _BusinessWebPage = null;
		#endregion

		#region Object Events
		protected override void OnInit(EventArgs e)
		{
			base.OnInit (e);

			// This must be outside the Page.IsPostBack testing
			// This should be before the OnLoad, so that the Page_Load can see it properly
			this.SetBusinessWebPage();
		}

		public void SetBusinessWebPage()
		{
			if (this.BusinessWebPage == null)
			{
				this.BusinessWebPage = (dcgBusinessWebPage) this.Page;
			}

When i click on a record in teh datagrid on FormA, I want all the controls on UC1 (which include UC2) to dispay the detail information, and that includes the user control UC2 (the combo box on UC2 displays drop down information pertaining to the record selected in the datagrid).
