Sandbox Visual Webpart: Visual Web Part are not Sandbox Solution by default

Quite recently I was with a task to develop a sandbox Webpart for the Office365 SharePoint site. 
So I started of with a sandbox SharePoint2010 empty solution and then added a Visual WebPart. After coding some logic I attempted to deploy the that by selecting deploy option and I encountered the following error. 

To solve error I downloaded Visual Studio 2010 SharePoint Power Tools from the following site:

The Correct Way:

  1. Create an Empty Solution of SharePoint 2010.
  2. Right click on the project under the solution and add new item.
  3. Select Sanbox Visual Webpart.
  4. Add some controls as per you requirement.
  5. After being done with the coding and successful building, right click on the project and select Package.
  6. This will create a .wsp file in \bin\debug\ folder.
  7. Now we need to upload this solution our Office365 site.
  8. Navigate to the site.
  9. Move to the site settings.
  10. Under  Gallery, select Solutions
  11. In the ribbon select Upload Solutions option.
  12. Browse to the .wsp file press upload.
  13. Then on the same screen select Activate option.
  14. Now navigate to the desired page and in the more webpart option in ribbon you will find you webpart

Reason Behind the Error

By installing above mentioned tool, I also got an option of Visual Sandbox solution in the Visual Studio 2010 installed templates. By using this template I was able to deploy my WebPart on my site directly and then later by generating the .wsp solution I uploaded the solution to Office365.
In principle, visual web-parts are not supported in the sandbox environment because of the fact that we have user control i.e. .ASCX  within the webpart control. The file is deployed to the _controltemplates virtual directory in the physical file system on each Web front-end server where as in a sandbox environment niether such access is granted nor it is possible to deploy physical files to the SharePoint root. Therefore here comes sandbox Visual webpart into play that makes our lives bit easier.

    Hey ud,
    I'm sorry for the belated reply. I did not see you comment in the first place.
    Anyways to my understanding you can get these control via jquery. I recently worked with jq for the getting the calender control and it worked quite fine. Let me know if you still have this problem.
    Cheers

SPFx: Develop using SharePoint Framework without Installing all the dependecies.

Image
SharePoint Framework (SPFx) has been around for more than 5 years now with being Generally available since Feb 2017.  In the recent times, its been possible to develop webparts for SharePoint on-prem as well using SPFx and with that it is getting harder to maintain multiple versions of required toolchains. e.g. Node. For M365 you can use the latest version of SPFx but probably you know, if you aim to develop webparts for the SharePoint Server 2016 platform, for instance, you need to use the SharePoint Framework v1.1.0 due to the server-side version dependencies. So yet another challenge is using the correct version of the SPFx and Nodejs for the particular project . Although I personally used to like Node Version Manager which lets you manage multiple installations of node.js on a Windows computer but still one needs to isolate SharePoint Framework dependencies if you are targeting multiple platform from on PC. 2nd Problematic scenario begins when you start developing SPFx extensi...

SharePoint Online: Elevated Permissions....with love

Image
Remember the good old days! when using RunWithElevatedPrivileges(SPSecurity.CodeToRunElevated), in the SharePoint server-side object model, would let us run our code (Full trust code) with full control i.e. granting us higher permission (as System Account) and letting us performs tasks that waren't permited to do in current user context.  Now, that, we have SharePoint addin and SharePoint online webparts, one still wonders if there is still a way of achieving that. Since there are use cases where a user needs a higher permission, for instance.  Changing a status of a field in a list where the current logged in user has read only permission.  Reading member of a SharePoint group.  In Workflows  like SharePoint Designer workflow you used to have App step, in Nintex workflow you have elevated permission and in MS Flow Impersonation is possible using connectors in Flow triggered by HTTP request can run under System account as show in the video below:  Other wa...

Powershell: Filling up an Existing Excel Sheet with data from SQL Server

Situation: The client required to have data from their SQL Server 2012 Database filled in to an existing Excel Sheet. This sheet had a table with around 40 columns of which 12 where to be filled by us and rest from different departments. I tried different solution for that since the requirements were not initially clear. Forexample OPENROWSET was tried. In this regards this link really helpful. Although this requires few configuration to be made on the server or to install e.g. ACE.OLEDB driver on server which was not possible in our case. So we decided to write a Powershell script and access SQL Now about the script: Take the file TestExcel.xlsx from C:\Temp folder Create its copy with the current date appended to its name.  Start reading the Excel file from Sheet "Specified Sheet Name" From Columns 1, it will take the name of the system.  Based on the name fill the excel sheet by executing the queries, here are the columns that are going to ...
