50 Limitations of SharePoint Sandboxed Solutions
1. Deployment at site collection level (No Web Application-scoped Features or Farm-scoped Features). So, If you have 100 site collections, then you have to deploy the same sandbox solution to 100 site collections.
2. No SPSecurity - Therefore no Elevated Privileges
3. You can't use SPSite object to get other site collections. (But you can use it to get current site as : SPSite site = SPContext.Current.Site)
4. Visual webparts are not supported (But you can use the "Visual Studio 200 SharePoint Power Tools" to get this functionality)
5. cannot call to the network resources. E.g. You cannot read/write to a database on the server (But you can use Silverlight)
6. Only "No code" workflows allowed. No Visual studio workflows (But the workflows without classes which are imported and edited in Visual studio will work!)
7. No support for System.IO, Therefore you Cannot read/write to the file system.(But you can use Web Services hosted in your on-premises and call from workflow)
8. HideCustomAction, CustomActionGroup are not allowed. But you can use <CustomAction>
9. Remember, Resource Usage Quotas/Limits applied on Sandboxed solutions http://msdn.microsoft.com/en-us/library/gg615462.aspx

ReplyDeleteAny one else experience frustration while converting a solution package to a sandboxed solution package. It's been quite a challenge for me because I have to look for work arounds to doing things like adding a web part to a page, programmatically adding an event receiver, and programattically editing the properties of a field.

ReplyDeleteI am unable to export more than 2000 records to excel from SharePoint external list. External list has 5000 records but only 2000 records getting exported to excel.
ReplyDeleteAny help on this would be highly appreciated.
Thanks in advance.
This is because of the throttling limit on External List. Use Set-SPBusinessDataCatalogThrottleConfig to increase the limit.
