I have a power bi report which i am embedding on my web application.
Is there is anyway that is can embed directly a drill down view of the report?
in short i want to open the report in drill down mode on.How can i do this programmatically.
I am using dot net mvc for my web application.
Yes, that is possible (assuming that you want to apply a "default" filter in your report). When you embed the report, you can add a list of filters to your embedConfig (documentation):
var embedConfig = {
...
filters: [...]
};
A single filter, in the list of filters, can look like the following (documentation):
const myFilter = {
$schema: "http://powerbi.com/product/schema#basic",
target: {
table: "Table1",
column: "Column1"
},
operator: "In",
values: ["A"]
};
In which case you specify the filters in embedConfig according to
filters: [myFilter]
However, note that this is not a secure way to prevent users from seeing data, a user can easily, using javascript, remove the filter and gain access to all the data.

I'm working on a project that contains Dynamics CRM and Portal Connector which built upon Sitefinity.
There is a way to retrieve data inside Portal Connector from Dynamic CRM called Saved Query and this way generate a URL for you to retrieve data by HTTP request in front-end but I don't want to access it by the front end I want to access the Dynamics CRM by Backened, specifically by Entity framework, is it possible to connect to Dynamic CRM by Entity framework and retrieve the data by C# then send it to View?
My apologies for not coming across your post sooner.
A better way is to use the CRM connection provided by the Portal Connector. It essentially wraps the CRM SDK so calls you want make to the SDK can be made here and it uses the CRM connection configured in the site.
https://www.crmportalconnector.com/developer-network/documentation/developing-for-tpc/Dynamics-CRM-Connection-API
// Required usings
using System;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Query;
using pavliks.PortalConnector.Crm.Connection;
// The Code
// Create an instance of the connection manager
CrmConnectionManager manager = new CrmConnectionManager();
// Use the Connection property of the manager to access the
// configured CRM connection and create a new account
Guid newId = manager.Connection.Create(new Entity("account")
{
Attributes = new AttributeCollection()
{
{"name", "My Account Name"}
}
});
// Create Query Expression
QueryExpression query = new QueryExpression("account")
{
ColumnSet = new ColumnSet(true),
};
// Use manager to query CRM
EntityCollection entities = manager.Connection.RetrieveMultiple(query);
All the required assemblies are already in the Sitefinity site bin folder as they come with the Portal Connector assemblies and are copied to that location with the Portal Connector during installation. If your code is in another project, either reference the assemblies in the Sitefinity project or add them from the Portal Connector deploy package to your project.
I know it's a bit late but I hope it helps you in your next portal project.
let me answer my question, in case anyone wants to do a similar thing in the future :
1- first thing connect to Dynamic CRM is not related to Portal Connector, so the area that you should search in is Dynamic CRM.
2- To connect to Dynamic CRM you should follow the below steps :
2.1- install this package "Microsoft.CrmSdk.XrmTooling.CoreAssembly"
2.2- find what is your connection string.
2.3 use below code
var service=new CrmServiceClient("AuthType=Office365;Url=https://ititisdf.crm4.dynamics.com;Password=1234" )/*put your connection string instead*/
3- Some example of you could create or retrieved data
service.Create(new Entity("account"){["name]="Test connection"}); // add record
// retrive data
//1- query expression
//var query= new QueryExpression().Criteria. <===== from here you can add filteration ... and so on
//2- fetch xml expression
//var query=new FetchExpression(#"fetch xml value"); // you need to use XrmToolBox to generate your fetchXml
//3- var query=new QueryByAttribute("account");
// query.AddAttributeValue("name","Test1");
var entities=service.RetrieveMultiple(query).Entities;
foreach(var entity in entities)
{
entity["name"];
}
var organization=new OrganizationServiceContext(service);
// below code is under a concept called late-bound
var result=(from account in organization.CreateQuery("account")
join contact in organization.CreateQuery("contact")
on account["primarcontactid"] equals contact["contactid"]
where account["gendercode"] == "test" AND account["industrycode"]=1
select new {
Name=account["name"],
ContactName=contact["fullname"]
}).ToList();
// to implement Early bound
1- go to XrmToolBox ==> About ==> Plugin Store ==> Early Bound Generator==>Early Bound Generator Page will opened choose Entity to skip and choose which entity to want to include and which want to exclude
===> choose the path of generated .cs class that will represent you Entity in your project ===> press on Create Entities ===> now copy the generated file .
Now you have something like Entity framework :
Just use Entity name as a normal class :
var account = new Account{Name="Ahmed"};
and instead of this :
organization.CreateQuery("account")
use
organization.CreateQuery<yourEntityName>()
Actually, I got all of this information from youtube serious related to Dynamic, and here is the link
note: this serious in the Arabic language for this reason I summarised the steps in this answer to make it helpful for all.
This topic might be opinionated. If it is so, apology. I need to assess the below questions:
Should I use ASP.NET MVC controller to generate chart and return the image to the client side?
If this approach is chosen, is there any reliable free MVC chart control that I could use?
Should I use Client Side charting control to generate chart and return the JSON data to be consumed by the client side?
If I go along using this approach, how to secure the data consume by the client side? I want to prevent the plain data is being copied over or read by simply view source feature of the browser.
Thanks!
Disclaimer: I didn't try this in ASP.NET MVC > 3, but probably works fine.
As a follow-up for my comments. If you need just: Bar Chart, Pie Chart, Column Chart, you can use ASP.NET Web Helpers Library https://www.nuget.org/packages/Microsoft.AspNet.WebHelpers/.
In your controller you'll have an action 'DrawChart' or something like this (for PNG format) :
public ActionResult DrawChart()
{
var chart = new Chart(width: 300, height: 200)
.AddSeries(
chartType: "bar",
xValue: new[] { "10 Records", "20 Records", "30 Records", "40 Records" },
yValues: new[] { "50", "60", "78", "80" })
.GetBytes("png");
return File(chart, "image/bytes");
}
And view : <img src="#Url.Action("DrawChart")" alt="Drawing chart with HTML Helper" />
An example here : http://weblogs.asp.net/jalpeshpvadgama/chart-helpers-in-asp-net-mvc3
Give a look at this library.
It uses a Canvas control (instead of PNG), giving you interactivity and animation.
The data are generate server-side (so you don't need to expose your datasource) and pass it to chartJS, an open source library that draws the graph.
I'am new in MVC. I'am currently working to transform a desktop to a web application.
I need to make an update to the user view when an event of an object occurred. I have an object that observe a humidity sensor. Let say This object will trigger an event when the humidity above 70%. The code might be like this:
Private Sub Humidity_Alert(sender As Object) Handles objSensor.Alert
'Update user chart
End Sub
In desktop application, I just make an update to the view as usual in realtime, but I don't have any idea yet how to return this event to the client in MVC, without using javascript timer to make an ajax call to request if there is any alert. How to solve my problem?
I would suggest using ASP.NET SignalR library: signalr.net
You can use it for real-time updates from server to client.
ASP.NET SignalR is a new library for ASP.NET developers that makes it incredibly simple to add real-time web functionality to your applications. What is "real-time web" functionality? It's the ability to have your server-side code push content to the connected clients as it happens, in real-time.
Some pseudo-code example:
SignalR Hub:
public class HumidityHub : Hub
{
public void RefreshChart(string data)
{
Clients.All.refreshChart(data);
}
}
ClientCode:
var hub = $.connection.humidityHub;
hub.client.refreshChart= function (data) {
//refresh your chart
};
$.connection.hub.start();
ServerCode:
var hubContext = GlobalHost.ConnectionManager.GetHubContext<HumidityHub >();
hubContext.Clients.All.refreshChart(data);
I am creating a site which will be accessible via mobile and desktop devices. So I want to create 2 views of my application. My action code and everything else in the backend (manageers, DAOs) is same. Just JSP changes for both.
How I can do this via Struts 2?
In struts there are many way to obtain the same thing.
In this case, the one I prefer is:
You could write an interceptor that changes the return code based on the user-agent of
the client, such that there would be versions for PC and mobile of each jsp.
In your configuration you need to have all the result codes for all jsp (or you could simply define the result through the wildcard mapping).
For example: change the result code from "success" to "mobile_success". In case you want map both results in the same jsp you can map, as I said before, in this way
<result name="*success">
not sure whether there is library for automating such task for struts 2. but if there is, using such libraries might be better
anyway, here is the theory. every browser has its own "signature" written in the request header, called "User-Agent". different browser (supposedly) has different user agent. for example, my firefox user agent is as following:
Mozilla/5.0 (Windows NT 6.0; rv:5.0) Gecko/20100101 Firefox/5.0 FirePHP/0.5
basically, by detecting the user agent, you can know what browser is used to access your site. the list of mobile browser user agents can be found in http://www.zytrax.com/tech/web/mobile_ids.html
if i'm not wrong, you can retrieve the user agent in server by httpServletRequest.getHeader("User-Agent"); (correct me if i'm wrong)
you can then create an interceptor which will decide whether a client is from mobile or from desktop. that interceptor can return different result for different client type. for example, if the client is desktop, you can return "successDesktop" and if the client is mobile, you can return "successMobile".
well, hopefully someone else can come up with (far) easier solution
I am currently trying to solve this very same problem. A framework would be nice, and I'm all ears if anyone has tested and approved one. That said, I can't find anything mature enough for me to be justify moving from Struts for the mobile view.
My best solution currently is to create actions for each of the parts of my full page which will be displayed on full browsers. Then to reuse those actions to display page segments on the mobile side.
I found trying to make one page look right for a desktop browser and a mobile browser simultaneously was not a sustainable approach.
jQuery mobile looks like a very promising library for styling the elements retrieved by struts.
So while it is surely possible to cram both versions of the site into one action I think taking the time to create small reusable actions that result in jsp snippits will pay off as your app scales.
Here are some possibilities for the near future:
(I can't add these as links as I don't have enough reputation...you'll have to add the 'http://www.')
Struts2 jQuery Mobile Project homepage: http://code.google.com/p/struts2-jquery/
Struts2 jQuery Mobile project: code.google.com/p/struts2-jquery/downloads/detail?name=struts2-jquery-mobile-showcase-3.1.1.war

#fajrian - using 'user agent' to determine a browser type could become a real pain as more and more mobile and desktop browsers are released. A better approach would be to determine whether to display a mobile version or full version based on the window's dimensions. A perfect example.
edit - Check out CSS3 media queries.
As Maurizio said you could use interceptors. Here is what I found.... http://www.benmccann.com/blog/struts-2-tutorial-interceptors/
This works for me and should basically get round the problem. You do need to know at least part of the user agent strings though:
public class MobileInterceptor extends AbstractInterceptor {
private static final String RESULT_CODE_SUFFIX_MOBILE = "mobile";
private static final String REQUEST_HEADER_ACCEPT = "Accept";
private static final String[] MOBILE_BROWSER_UAS = {"iPhone OS","Android","BlackBerry","Windows Phone"};
public String intercept(ActionInvocation invocation) throws Exception {
invocation.addPreResultListener(new PreResultListener() {
public void beforeResult(ActionInvocation invocation, String resultCode) {
// check if a wireless version of the page exists
// by looking for a wireless action mapping in the struts.xml
Map results = invocation.getProxy().getConfig().getResults();
System.out.println("Results:"+results.toString());
if(!results.containsKey(resultCode + RESULT_CODE_SUFFIX_MOBILE)) {
return;
}
// send to mobile version if mobile browser is used
final String acceptHeader = ServletActionContext.getRequest().getHeader(REQUEST_HEADER_ACCEPT);
//Get User Agent String
String userAgent = ServletActionContext.getRequest().getHeader("User-Agent");
System.out.println("UA: "+userAgent);
//Boolean to indicate whether to show mobile version
boolean showMobileVersion = false;
//Run through each entry in the list of browsers
for(String ua : MOBILE_BROWSER_UAS){
if(userAgent.toLowerCase().matches(".*"+ua.toLowerCase()+".*")){
showMobileVersion = true;
}
}
if(showMobileVersion) {
invocation.setResultCode(resultCode + RESULT_CODE_SUFFIX_MOBILE);
}
}
});
return invocation.invoke();
}
I came across a sample MVC3 code which had following in the Global.asax file:
public static void RegisterGlobalFilters(....)
{
filters.Add(new MyFilter1());
....
var provider = new MyFilterProvider();
provider.Add(c => c.HttpContext.IsDebuggingEnabled ? new MyProvider2() : null);
FilterProviders.Providers.Add(provider)
}
Both MyProvider1 and MyProvider2 are implemented with IResultFilter, and I am confused why one of them is added to FilterProviders and the other one is registered as a global filter.
Why and when should we add custom filters on FilterProvider, and why and when should we register them as global filters?
When you add a filter to GlobalFilters.Filters the filter will get executed for every request.
When you add an IFilterProvider to FilterProviders.Providers the filter provider will have a chance to decide whether a particular filter applies to the current request.
FilterProviders gives you greater control while GlobalFilters makes it easy to register a filter for the entire site.
