Body
Here are simple provider and consumer Web Parts. The provider UI accepts a text field that it passes to the consumer Web Part which simply outputs it. The connection between the Web Parts is the following interface: <pre><code>namespace ConnectedWebParts { public interface IParcel { string ID { get; } } } </code></pre> The Provider Web Part implements this interface and must have a method with the attribute ConnectionProvider that returns itself (since it implements the interface): <pre><code>namespace ConnectedWebParts { public class ProviderWebPart : WebPart, IParcel { protected TextBox txtParcelID; protected Button btnSubmit; private string _parcelID = ""; protected override void CreateChildControls() { txtParcelID = new TextBox() { ID = "txtParcelID" }; btnSubmit = new Button() { ID = "btnSubmit", Text="Submit"}; btnSubmit.Click += btnSubmit_Click; this.Controls.Add(txtParcelID); this.Controls.Add(btnSubmit); } void btnSubmit_Click(object sender, EventArgs e) { _parcelID = txtParcelID.Text; } [ConnectionProvider("Parcel ID")] public IParcel GetParcelProvider() { return this; } string IParcel.ID { get { this.EnsureChildControls(); return _parcelID; } } } } </code></pre> The Consumer Web Part must define a method with a ConnectionConsumer attribute that accepts an object that implements the connection interface (the provider Web Part) as a parameter: <pre><code>namespace ConnectedWebParts { public class ConsumerWebPart : WebPart { protected IParcel _provider; protected Label lblParcelID; protected override void CreateChildControls() { lblParcelID = new Label(); if (_provider != null && !String.IsNullOrEmpty(_provider.ID)) lblParcelID.Text = _provider.ID; this.Controls.Add(lblParcelID); } [ConnectionConsumer("Parcel ID")] public void RegisterParcelProvider(IParcel provider) { _provider = provider; } } } </code></pre>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
