Open the About. aspx page and switch to the Design view. As Figure 4 illustrates, the Left. Column. Content Content. Place.

Holders default content and is useful in scenarios where the content for some region is common among the majority of pages, but needs to be customized for a small number of pages. Step 3 explores specifying default content in the master page. Currently, Default. Content controls for the head and Main. Content Content. Place. Holders it does not have a Content control for Left. Column. Content. Consequently, when Default. Left. Column. Content Content. Place. Holders default content is used. Because we have yet to define any default content for this Content. Place.
