Can i use Report viewer web part in SharePoint 2013 app to show SSRS reports?

Can i use Report viewer web part in SharePoint 2013 app to show SSRS reports?

SharePoint app you mean a simple sharePoint 2013 application like site, team site etc, or do you mean an App (the new feature like webPart).
To add a SSRS Report viewver web part follow these steps
1. Edit the page
2. Choose insert a webpart
3.Select SQL server Reporting -> SQL Server Reporting Services Report Viewer webpart
4. Configure the webpart to show your .rdl files.

Unable to open any Sharepoint 2013 Apps

Hi all,
I am having an issue whenever I try and open third-party SharePoint 2013 Apps on our on-premises server. I have configured the app domain as per
http://technet.microsoft.com/en-us/library/fp161236(v=office.15).aspx and installed some random third-party apps (eg. "Yammer App for SharePoint", "Corporate News App").
I can go to the Microsoft Store and purchase apps and make them available to sites, however whenever I go to any of these sites "Site Contents" page and click to open any of the Apps it ends up redirecting the user back to the top-level sites homepage.
Initially it was freezing on a blank page, but looking through the logs on the server there was an authentication error with a service account password. Having resolved that issue it now just returns to the homepage of the top-level site.
Looking through the logs it appears that it gets redirected to the appropriate app domain URL, it then gets an Access Denied errors and attempts to redirect to an "Authenticate.aspx" URL in the apps domain. It then seems to fail authenticating
with "Attempted to perform an unauthorized operation" and go back to the top-level site.
A copy of the log file can be found at:
http://insertdisk.com/log.txt
The main sites web application is configured to use claims-based authentication via ADFS, anybody have any ideas?

Hi ,
According to your description, my understanding is that you encountered an authentication error
when you try to open third-part SharePoint 2013 Apps on your on-premises server with ADFS authentication.
Configuring the app domain is
necessary for setting up SharePoint Apps Development environment. If you just install and open third-part SharePoint 2013 Apps, it is not necessary.
Also for your issue, you can have a look
to the blog:

Network Load Balancing between SharePoint 2013 App server and WFE

Hi,
Can we do NLB between SharePoint 2013 App server and WFE Server ?
Below is our Architecture,
1. WFE Server (1)
2. APP Server (1)
3. Database Server
4. Domain Controller
We have configured NLB but, when we stop IIS on APP server, SharePoint 2013 web app link is not working.
is it possible ?
Please help us

You can do NLB between WFE and APP server however make sure that web application service is started from central admin which host sharepoint sites.
Why do you stop IIS on APP server, definitely it will not be able to host web app sites. rather you can just disable APP node on NLB to test it.

We have our SMTP server under port number 141 and we should add username and password. but inside SharePoint 2013, I can only define the SMTP server name , from email, reply-to . But there are not fields to define the port number , the username and password.
So can anyone advice from where I can define the port number and other field settings for the SMTP server ?

Integrate Workday and ServiceNow applications with SharePoint 2013 online

Hello, we have to integrate Workday and ServiceNow applications with SharePoint 2013 online and need to display data from these applications
to SharePoint 2013 intranet site.
Any information about the integration of Workday and ServiceNow applications with SharePoint 2013 would be greatly appreciated. Thanks!

Shailendra

Hi Shailendra,
I searched a lot, there seems very few information from internet and internal about this topic, I'm not familiar with Workday and ServiceNow applicaitons, I would recommend you may post in the following community sites(which should be offcial
sites) for a better assistance regarding the integration questions between Workday and ServiceNow and SharePoint Online(O365).

SharePoint 2013 App Custom Action in Wiki Page

Hi
I am trying to create a SharePoint 2013 App that also has a Custom Action that has to be visible in Pages tab. Code below
<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">

<CommandUIHandler Command="COB.NewGroupInExistingTab.Command.Notify"
CommandAction="~remoteAppUrl/Pages/Default.aspx?{StandardTokens}"
/>
</CommandUIHandlers>
</CustomAction>
</Elements>
The above code works fine, but I want the Custom Action to Open in a new Pop up box, like
javascript:SP.UI.ModalDialog.showModalDialog({ url: 'www.google.com', title: 'Default' });
The movement I change the CommandAction to JavaScript, the app breaks, if I remove the ~remoteAppUrl/Pages/.... the app does not work, it does not apper in the site content. and in appcatalog it shows wrong version number and says Valid App package
as no. what am I doing wrong.

Hi Carl,
As a security policy, a new customer cannot upload images and links. You can try to add links as text and upload your images to Onedrive and share it temporarily.

How to create Ticket Booking Functionality in SharePoint 2013 App?

We have created a Ticket Booking site in Asp.Net.
In that in Ticket Booking page user can book the ticket and the booked seats will be stored in the database. If there are any booked seats it will be disabled for the user and from other user can book tickets.
Took reference from this site:
http://techbrij.com/online-ticket-booking-system-asp-net-sql-server
Now I want to do same functionality using SharePoint 2013 App Part with SharePoint Hosted App.
I don't know how to start
Anybody having Idea.
Thanks in Advance.

Hi,
According to your post, my understanding is that you want to create a Ticket Booking solution as SharePoint Hosted App.
To build the similar solution in SharePoint, I would suggest you take a look at the links below about how to create ShrePoint Hosted App for a quick start:
Create Host App:
How to: Create a basic SharePoint-hosted app
Create App Part:
How to: Create app parts to install with your app for SharePoint
Then for the data storage, here is a documentation will provide more information:
App data storage:
Data storage options in apps for SharePoint
For the responsive UI, HTML plus JavaScript would be OK.
Feel free to reply if there are still any questions.

Setting up SharePoint 2013 Apps in a load balanced environment

All,
Looking for some articles on how to configure SharePoint 2013 Apps in a load balanced farm (2 WFEs, 2 APP servers, 2 SQL DBs).
Thank you!

if the load balancing environment is already well configured, thes rest is very easy, there is no difference between a configuration of load balancing environment and a simple one, for you that is transparent, except the manual deployment and manual copying
of files in the directory 15

Unable to update rating (rating column) on host document using JavaScript Object Model API inside sharepoint hosted apps

Hi Everyone,
We are developing SharePoint hosted apps for Office 365, for that we are going
to implement document rating functionality inside Sharepoint app. The host web contain document library (“Documents”) and from apps we need to rate each document. The rating functionality working fine with CQWP in team site using
JavaScript Object Model API.
But the same code is not working inside apps and giving error:-
If we are using app context than error will be:-
"List does not exist.
The page you selected contains a list that does not exist. It may have been deleted by another user."
And for Host context than error will be:-
"Unexpected response data from server."
Please help on this
Please see below code..

Thank you in advance! :-)


Hi,
According to your post, my understanding is that you want to update list column in SharePoint hosted apps using JavaScript Client Object Model.
Based on the error message, it seems not retrieve the list object in context. I suggest you debug the code step by step using Internet Explorer Developer Tools to
find the problem.
Here are some demos about using JavaScript Client Object Model in SharePoint hosted app:

Server Error: Unexpected Error when running Napa SharePoint 2013 App

I am getting an error "Server Error : Unexpected error" when I try to run a SharePoint 2013 app in Napa Development environment.
It starts the process normally but after it shows "Uninstalling previous version" it throws the error. This has been happening since yesterday.Someone help

I have a solution to the problem. I had a folder with a JSON file. On renaming the file to .txt, the app ran normally. I believe .json files are not supported in SharePoint hence the error.

Possible to use both Tabular and Multidimentinal with same SharePoint 2013 farm?

I would like to build SharePoint 2013 based reporting portal with Power View as visualization tool.
Is it possible to install both Tabular and Multidimentional to same physical server?
Is it possible that some Power View reports use tabular and others multidimentional?
Could above requirement work in production environment? Anybody tried?
Kenny_I

Hi Kenny_I,
According to your description, you are going to create a PowerView report using SQL Server Analysis Services Multidimensional database or SSAS tabular model as data source in SharePoint 2013, now what you want to know is that is it possible to install both
Tabular and Multidimensional to same physical server? And is it possible that some Power View reports use tabular and others Multidimensional?
Of course we can install both Tabular and Multidimensional to same physical server that had SharePoint 2013 installed. In my tested environment, I have installed all of them on the same server. And we can use tabular model and others Multidimensional database
on individual PowerView report. However, it seems that we cannot use both tabular model and others Multidimensional database on the same Powerview report.
Even though we can install both Tabular and Multidimensional to same physical server, however in the production environment, the recommendation is that install them on different server, it will beneficial to troubleshooting the issue when some issue occur
on the environment.
If you have any questions, please feel free to ask.
