Deleting error webpart without using designer

          I was using a ReportViewerWebPart webpart at my home page. Sometimes during deployment this cause trouble that i could not open my home page since in some servers reports was not configured. I was resolving it using Sharepoint designer. I would open up my home page with sharepoint designer delete the webpart and now i could open my home page.

         Now i have found an alternate solution for this. We could use Web Part Page Maintenance for deleting this error web part. The solution is,

Procedure:

     Add the value ?Contents=1 at the end of your site.

     It now looks like http://yourservername/sites/yoursitename?Contents=1

     Hit Enter, that leads you to webpart maintenance page.

        

  The "Open on Page" shows error if that webpart contains error. you can select that particular webpart and delete it.

     Now the error webparts in homepage is deleted and the home page is displayed without the error webparts.

Different types in Updating Sharepoint List

            While creating Event Receivers or Workflows we need to update the list or list items using SPListItem method. However there are different types in updating. Most commonly used are Update and SystemUpdate. lets see the different types of updates and its use.

Update()

• Updates the item in the database.
• Updates the “Modified” and “Modified by” values.
• Creates a new version.

Systemupdate()

• Updates the item in the database(List).
• Does not update build in columns "Modified" and "Modified By".
• Does not increment item version.
• Triggers the item events.

Systemupdate(true)

• Updates data to database(List).
• Does not update build in columns "Modified" and "Modified By".
• Will increment Item Version.

Systemupdate(false)

• Updates data to database.
• Does not update build in columns "Modified" and "Modified By".
• Does not increment item version.

UpdateOverwriteVersion()

• Updates data to database.
• Updates build in columns "Modified" and "Modified By".

Note :

You can also disable the triggering of events by using “this.EventFiringEnabled = false;”. Do your update and enable the events again with “this.EventFiringEnabled = true;”
