So far, when you edit a SharePoint list item, a form pops up for Edit. If you need to edit many items, there is a more convenient way, which is to enable a little known feature called Inline Edit using SharePoint Designer 2010. This recipe will demonstrate how to enable and use this feature.
Ensure SharePoint Designer 2010 has been opened to the Chapter 4 URL:
From the Navigation section, under Site Objects, choose Lists and Libraries.
In the Lists and Libraries that appear, select the Proposals library.
From the Proposals tab, under the View section, click on All Documents. This is actually a link that will open the AllItems.aspx page for the Proposals library in editing mode.
With the List View Web Part highlighted, note the new List View Tools sectionthat appears in the ribbon with Options, Design, Web Part, and Table tabs, as shown in the following screenshot:
Click on the Inline Editing icon. And that is it!
Press the Save icon to commit the change...
