found in the Schema property of the IWebPartRow interface. The Schema contains information, such as the name and type, about all columns in the row. When a column with the name URL is found in the row, this Web Part assumes that it s a URL column. The column is transformed into a SharePoint SPFieldUrlValue object. From this object the Url property is retrieved and put into the Web Part RssFeedUrl property. If no column called URL is found, it sets the feed URL to null. That s all you need to connect the custom RSS Web Part to a standard SharePoint Links list. Deploy the solution and go to your site. Use an existing Links list or add a new one, and then fill the list with a few links to RSS feeds. When you ve done that, create a new page and add the Links list to that page and then the RSS Web Part. Click Edit Web Part on the Links list options menu; then once again in the options menu of the Web Part, select Connections > Send Row of Data To > RSS Web Part. Click OK in the edit pane of the Web Part. Now the Links list is connected to the RSS Web Part and you can see that the Links list has a new column called Select. If you click the Select icon on any of the rows, the RSS Web Part displays the contents from the URL of that selected row in the Lists Web Part, as shown previously in figure 14.10.

The third connection type that I ll show you is an alternative to the IWebPartRow when you need to select a list column to send to the consumer during the connection. The interface you ll use for this is called IWebPartParameters. This approach is better than iterating over the columns in the row as in the previous sample because it doesn t depend on a specific hardcoded name of the column. The connection provider interface requires that the consumer tell the provider which field or fields to send to the consumer. You must add the connection endpoint to the RSS Web part and mark it as a connection consumer endpoint:

This implementation differs from the previous ones because it s not just storing the value of the connection endpoint. In this case you need to inform the provider Web Part about the property (or properties) that you d like it to provide to your consumer. You do so by creating a PropertyDescriptorCollection that consists of PropertyDescriptor objects. In this example, the property you need is a string to set the feed

B, using the current Web Part type, the name (RssUrl), and the type of property. The collection of property descriptors is then used with the SetConsumerSchema method of the connection provider interface before the connection instance is stored to a local variable. Using the property descriptors and the configuration of the connection, the provider Web Part will know which property to send to the consumer. The connection configuration is determined when the connection is established in the user interface. Before modifying the OnPreRender method to support this new connection endpoint, you have to update the IsConnected method once again. It ll now check whether the Web Part is connected to any of the three connection endpoints:

TypeDescriptor object
internal bool IsConnected() { return _provider != null || _row != null || _parameters != null; }
You then update the OnPreRender method so that it ll retrieve the feed URL from the new parameterized connection:
protected override void OnPreRender(EventArgs e) { if (IsConnected()) { if (this._provider != null) { this.RssFeedUrl = this._provider.Url; } else if (this._row != null) { this._row.GetRowData(getRowData); } else { this._parameters.GetParametersData( getParametersData); } } renderFeed(); base.OnPreRender(e); }
