Best Option To Retrieve Analysis Services (SSAS) Cube Data Dynamically In MVC
Mar 18, 2011I need to dynamically add/remove dimensions and facts in web application and get results from SSAS. The cube in SSAS is defined and ready to use. So far the best idea I found is use MDX queries to get metadata from SSAS cube and display those data in web page. Then user can choose needed dimensions/facts and I need to costruct dynamic MDX query and get results from SSAS. Communication with SSAS is made with AdomdDataReader. Is there better options to solve this task that require less effor? Maybe somehow make use of Reporting Services (SSRS).

.net - Control Concurrency : Syncing Data Through Web Services?
Jan 4, 2011Actaully i developed an Asp.net website which has a PDA app part. The case is that employees from company come in the morning and get data in their PDA's and they work on them the whole day and in Evening they again come to office or from any web access they update the data on server. We did this through Web services because web services are remote methods so they could access that by only web access..
Now the problem is Concurrency that while syncing through web servies how to control Concurrency however their could be many employee who try to update data at a time.In web servies we receive DataTable from PDA application and do update or insert operations through LINQ with Sql Server.

WCF / ASMX :: Data Being Returned By Web Services But Result Object Is Nothing?
Nov 10, 2010I have a .net app consuming a java web service. I added the web reference in visual studio to the proper wsdl, it created the proper proxy class and I can call the web service without any problems but looking at the result that is returned, it is always nothing. I can see, by using Fiddler, that the response is returning what it should. If there is a response, why is the return object never being populated and no errors are thrown?
View 2 RepliesObject Data Source With Reporting Services In Visual Studio?
Oct 12, 2010I'm working on a site where we want to include a pie chart on a page. Right now I'm working on implementing that through Reporting Services (RDLC file) with an object data source.The SelectMethod of my object data source is a method that returns a list of business objects; lets say a List<Alpha> and Alpha has a sub object Beta with a Name property. In my report definition I have set the Category groups to be: =Fields!Beta.Value.Name this means that Alpha.Beta.Name are my pie slices. I got the following error:
An error has occurred during report processing. The Group expression for the rouping 'chart1_CategoryGroup1' contains an error: Object variable or With block variable not set.I was able to confirm this is because Beta is nullable and was able to fix the issue by updating the object Alpha to return a new Beta() if the Beta property is null. This solution is not ideal though because there are other places in my code where I need Beta to be null if it doesn't have a value yet.Is there a way to update the report definition to accept a null property as valid? Ideally I would like to specify the value as "Not Set" if Beta is null.
C# - Why Is System.Data.Services.MimeTypeAttribute Now Only A Class Level Attribute
Apr 7, 2010I'm getting started with Astoria/ADO.NET Data Services/WCF Data Services. Looking through a lot of the code samples out there, it appears that the MimeType attribute used to be a method level attribute. After installing the latest update, it is now a class level attribute.
If I have more than one Service Operation that I want to return as a certain MimeType, then it appears now that I have to create a new service for each operation. Is this correct?
Most examples are like this:
[WebGet]
[SingleResult]
[MimeType("application/pdf")]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}
I get "Attribute 'MimeType' is not valid on this declaration type. It is only valid on 'class' declarations." when I compile, because now I can't do this.
Now, I have to do this:
[MimeType("FooPDF", "application/pdf")]
public class FooService : DataService<FooDBEntities>
{
public static void InitializeService(DataServiceConfiguration config)
{
config.SetServiceOperationAccessRule("FooPDF", ServiceOperationRights.All);
}
[WebGet]
[SingleResult]
public IQueryable<byte[]> FooPDF()
{
var result = from p in this.CurrentDataSource.MyPDFs
where p.FooID == 2
select p;
return result.Take(1).Select(p => p.PDF);
}
}
What's worse is that I can't add duplicate MimeType attributes to my class.

How To Retrieve A Subset Of Data From Entity Object Data Source And Pass To Another Page/
Oct 8, 2010I am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)
This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid
