When you want to create a SharePoint 2010 sandbox branding solution, you will notice that your files will be in draft (Checked out). This means that these files are not available yet for all users. Therefore two actions need to be done for each file:
- Check in the file;
- Approve the file. As an example I deployed a master page using a sandbox solution. When the solution is deployed and the feature is activated, the master page file has the following properties.
As you can see the file is not checked in and the approval status is still draft.
A solution is to check in and approve the file when the feature is activated.
Create a feature event receiver for the feature that deploys the branding files (in this example this is a Site Collection feature), and write code for the FeatureActivated event.
The following code retrieves the file, checks it in, and approves it.
When the new solution is deployed, you will see that the file is now a major version and approved.
