Generator Quick Response Code in C#.NET Using and configuring Web Parts in SharePoint 2010

If a page is personalized, SharePoint uses the Personal view by default. If you want to make changes to the Shared view, select User > Show Shared View. Use the same menu to switch back to the Personal view by selecting Show Personal View. If you re a wiki page editor and want to create a Personal view of the page, you have to add PageView=Personal to the URL of the page, as in

Likewise, this parameter can be used to show the Shared view, by appending PageView=Shared to the URL. In standard Web Part pages, choose Users > Personalize This Page to create a Personal version of the page.

Closing and deleting Web Parts One very important thing to keep in mind is that there s a big difference between closing and deleting Web Parts. Deleting a Web Part does exactly what it says; it removes the Web Part from the page, including all customization and personalization. Closing a Web Part, on the other hand, only makes the Web Part invisible the Web Part is still loaded when the page is rendered but it doesn t do anything. If the user wants to remove a Web Part from a personalized page and the Web Part is added to the Shared view, the user only has the option to close the Web Part because it can t be deleted from the Personal view. Having a lot of closed Web Parts can cause performance implications for your site both in terms of speed and storage. In chapter 4, I ll show you why it can slow down your page, and, in chapter 5, you ll learn how to prohibit the users from closing Web Parts. All closed Web Parts are accessible through a special group in the Web Part Gallery for the page called Closed Web Parts. This is a virtual group and only appears in the gallery when there are closed Web Parts. It doesn t correspond to any group in the site collection s Web Part Gallery; it exists only for the actual page. To restore a closed Web Part, select the Web Part from the Closed Web Parts group and add it back to any zone on the page. Maintenance view If you re editing a page and you want to ensure that any changes you make are reflected for all users, you can remove all Personal views for that page by appending Contents=1 to the page URL for example:

This will redirect you to the /_layouts/spcontnt.aspx page, called the Web Part Maintenance page (see figure 2.10). This page will display all Web Parts that are used on the page without loading and rendering them. It will show Web Parts that you won t see in the normal views for instance, if they re closed, hidden, or in any way failing. This application page can be used to reset, close, or delete Web Parts. If you have a Web Part that fails and crashes the whole page you re using, perhaps due to bad error handling in your code or someone else s, enter the Maintenance

Figure 2.10 The Maintenance View of a page can be used to close, reset, and delete Web Parts from the Shared or Personal Views when, for instance, a Web Part fails to load and makes the whole page inaccessible.

mode of the page and delete the failing Web Part(s). Simply check all the Web Parts that you d like to remove and click the Delete link. If you select to close a Web Part instead, it s not removed and you can restore it as described in the previous section. You can reset Web Parts if you ve reconfigured a Web Part in the Shared view and you d like to remove all personal settings. This approach will reset the selected Web Parts in all Personal views to the current Shared view configuration. Using the SharePoint web interface to customize Web Parts and build simple mashups is just one method. Sometimes using the free tool called SharePoint Designer 2010 is the better choice.
