Create or change a connection between two Web Parts
By using menus and dialog boxes, you can connect Web Parts, pass data between them, and synchronize their behavior.
- Open the Web Part Page.
- On the Site Actions menu
, click Edit Page.
- Decide which two Web Parts you want to connect. You can create or change the same connection by starting from either Web Part.
- From either one of the Web Parts, click the Web Part menu
, point to Connections, point to the type of connection that you want to create or change, such as Provide Row To or Get Sort/Filter From, and then click the name of the Web Part for which you want to create or change a connection.
The Web Part menu may not be enabled or visible on your Web Part Page for several reasons, including that the Web Part or the zone does not support connections, you are using a browser that is not compatible with Windows SharePoint Services, or connections are disabled on your site.
- For some Web Part connections, you might need to select additional information in the Configure Connection dialog box. For example, you might need to select the connection type that you want to use or a column that you want to filter. Also, depending on how one or both of the Web Parts were created, you may see additional dialog boxes that are unique to the Web Part connection. For more information, see the Help information, if any, for the custom Web Part.
Tip You can hide a Web Part if you want to use it to provide data to another Web Part through a Web Part connection, but you don't want to display the Web Part.
