<para>This interface is designed to be used with Web Parts connections. In a Web Parts connection, two server controls that reside in a <see cref="T:System.Web.UI.WebControls.WebParts.WebPartZoneBase" /> zone establish a connection and share data, with one control acting as the consumer and the other control acting as a provider. The mechanism for sharing data in a Web Parts connection is an interface instance, which the provider serves to the consumer by means of a callback method. To establish a connection, the consumer and provider must both work with the same interface type for sharing data. If the consumer does not recognize the interface type sent by the provider, it is still possible to connect the controls by means of a transformer (a <see cref="T:System.Web.UI.WebControls.WebParts.WebPartTransformer" /> object) that translates the interface instance sent by the provider into a type that the consumer recognizes. For details on connections, see <see cref="T:System.Web.UI.WebControls.WebParts.WebPartConnection" /> and <format type="text/html"><a href="d98cfd0f-ebd6-4871-89d5-abbd2cdef67b">Web Parts Connections Overview</a></format>. </para>

<para>The <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartRow" /> interface is a provider interface included with the Web Parts control set as a standard interface for creating connections based on a data row. You can also create custom interfaces to use with Web Parts connections, but in many data-driven Web applications, it is useful to create connections based on a common field (for details, see the <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartField" /> interface), table (for details, see the <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartTable" /> interface), or row from the data source. In a typical connection, a <see cref="T:System.Web.UI.WebControls.WebParts.WebPart" /> control acting as a provider would implement the <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartRow" /> interface and provide an instance of the interface to consumers in a special callback method. For example, the provider might implement an <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartRow" /> interface for a row that corresponds to a user in your user information table. Another <see cref="T:System.Web.UI.WebControls.WebParts.WebPart" /> control acting as a consumer would define a special method to receive the interface instance, and could then extract the user data, use it to look up additional information about that user's accounts, and display all the information related to that user on the page.</para>

<para>The <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartRow" /> interface has two exposed members. The <see cref="P:System.Web.UI.WebControls.WebParts.IWebPartRow.Schema" /> property returns schema information about the data row encapsulated in a <see cref="T:System.ComponentModel.PropertyDescriptorCollection" /> object. The <see cref="M:System.Web.UI.WebControls.WebParts.IWebPartRow.GetRowData(System.Web.UI.WebControls.WebParts.RowCallback)" /> method declares a method that an implementer (such as a provider control) uses to retrieve the interface instance's row data when the callback method is invoked.</para>

<para>This property provides property information for the data. Using the <see cref="T:System.Web.UI.WebControls.WebParts.IWebPartRow" /> interface in a connection, you get a <see cref="T:System.ComponentModel.PropertyDescriptorCollection" /> object, which is referenced by the <see cref="P:System.Web.UI.WebControls.WebParts.IWebPartRow.Schema" /> property. The contract specifies that calling Schema[n].GetValue(RowData) returns the value of the nth column in the row. You need to use the <see cref="P:System.Web.UI.WebControls.WebParts.IWebPartRow.Schema" /> property to get the values in the row.</para>
