I'm attempting to use business objects as a datasource for an ASP.NET Microsoft rdlc Report and I am having problems displaying the values of subobjects in the report.
For example, if have the following two classes 'Customer' and 'Address'.
Customer
FirstName
LastName
Address
etc.
Address
HomeAddress1
etc.
Customer contains an instance of Address. If I set a list of Customers as the report datasource, I can refer to the values of each customer in the report as follows:
=Fields!FirstName.Value
However, I can't work out how to refer to the values of the 'Address' sub-object. I had assumed one of the following would work:
=Fields!Address.HomeAddress1.Value
or
=Fields!Address!HomeAddress1.Value
But neither of these do. Can anyone advise?
I had the exact same problem, and I'm sorry to say that I haven't found a way to reference sub-properties (I do hope that someone else has one though!)
What I ended up doing is creating a wrapper class that has all the properties I need directly in it.
The following syntax seems to work.
=Fields!Address.Value.HomeAddress1

I am working on an already started Delphi project where there is a TDBGrid. The grid seems to be filled by a TADOTable that refer to a Bill table in the dataset.
It display a bill by PkBill. I can't seem to find where in the design or in code someone told to load only for this pk.
I need to load multiples Pk at the same time. I'm used to create programmatically a TADOQuery, create a connection, write my SQL code, then do what I want with the result. With those objects/controls, I just don't know where to do that.
Thanks for the help and clarity!
Check TADOTable.MasterSource to see if it's in the Master-Detail relationship.
Or you could check TADOTable.Filtered and TADOTable.Filter to see if it's being filtered by PkBill.
it might be possible I'm searching for the wrong keywords, but so far I couldn't find anything useful.
My problem is quite simple: At the moment I get a list of individual Ids through a report parameter, I pass them to a procedure and show the results.
The new request is like this: Instead of showing the list for all individuals at once, there should be a list for each individual id.
Since I'm quite a beginner in srss, I thought the easiest approach would be the best: Create a subreport, copy the shown list, and create a subreport per individual id.
The amount of this IDs is dynamic, so I have to create a dynamic amount of subreports.
Funny enought, this doesnt seem to be possible. This http://forums.asp.net/t/1397645.aspx url doesnt show exactly the problem, but it shows the limit of the subreports.
I even ran trough the whole msdn pages starting http://technet.microsoft.com/en-us/library/dd220581.aspx but I couldnt find anything there.
So is there a possibility, to create a loop like:
For each Individual ID in Individual IDs, create a subreport and pass ONE ID to this?
Or is there another approach I should use to make this work?
I tried to create a 'Fake'-Dataset with no sql query but just for iterating the id list, but it seems the dataset needs a data-source...
As usual, thanks so far for all answers!

You didn't provide much detail about what sort of information needs to be included in the subreport, but assuming it's a small amount of data (say, showing a personnel record), and not a huge amount (such as a persons sales for the last year), a List might be the way to go.

All datasets require a data source, though if you're merely hard-coding some fake return data, any data source will do, even a local SQL instance with nothing in it.
I am running a query on a product. I need a field that will look at the user defined field which contains another product and check that stock level. Any help would be great.
What is the main objective?
Are you trying to check on that item because that item is the material/component? or act like a substitution?
Using UDF is quite not feasible as you have to get the link to the Item Master Data, and I have not figured out yet how to do that.
But if you are using it as substitution, why don't you use Alternative Item in Inventory > Item Management > Alternative Items? It will show on Sales Quotation for you to display it to customer. Or during Sales Order, you can get it displayed for alternative should your main item is shortage.
If you are using those item as a component, I suggest you use Bill of Material. During Production Order you will be able to see those component's availability in qty, and also you can have more than one, unlike UDF.
Hope this helps.
I think the key part you're missing here is the naming convention which SAP adpots for user defined fields.
Correct me if I'm wrong, but it seems that you're capable of querying these fields from a SQL point of view.
UDFs by defuault, will have their column name prefixed with "U_".
For example, the UDF 'AnotherProduct' will be referred to in SQL as 'U_AnotherProduct'.
Hope this helps, if not, please explain your problem in some more detail.
I am looking for a solution or to be told it simply is not possible/good practice.
I currently have a database whereby I can create new orders and select from a lookup table of products that I offer. This works great for the most part but i would also like to be able to add random miscellaneous items to the order. For instance one invoice may read "End of Tenancy Clean" and the listed product but then have also an entry for "2x Lightbulb" or something to that effect.
I have tried creating another lookup table for these items but the problem is i don't want to have to pre-define every conceivable item before I can make orders. I would much prefer to be able to simply type in the Item and price when it is needed.
Is there any database design or workaround that can achieve this? Any help is greatly appreciated. FYI I am using Lightswitch 2012 if that helps.
One option I've seen in the past is a record in your normal items table labeled something like "Additional Service", and the application code will recognize this item and also require you to enter or edit a description to print with the invoice.
In the ERP system which we have at work, there is a flag in the parts table which allows one to change the description of the part in orders; in other words, one lists the part number in the order and then changes the description. This one off description is stored in a special table (called NONSTANDARD) which basically has two fields - an id field and the description. There is a field in the 'orderlines' table which stores the id of the record in the special table. Normally the value of this field will be 0, which means that the normal description of the part be displayed, but if it's greater than 0, then the description is taken from the appropriate row in the nonstandard table.
You mean something like this?
(only key attributes included, for brevity)
I have a search form and result list. The form allows the user to search on the entity properties and related entity properties.
NameContains
EmailContains
CompanyNameContains
The result list displays the contact properties and the relevant related properties, in this case company name
Name | Phone | Email | Company
Company is a relation and for this scenario the relation is eager loaded. Everything is working fine for the search side, filtered results, paging, etc.
I'm using DetachedCriteria and I can only get the sorting to work on Contact properties. (actually don't need sorting on the emails and phone numbers really). I am having trouble sorting on Company Name which is the related property. I wondered if anyone could point me in the right direction. Thanks in advance for you assistance.
Hmm, I would think that something like this should do the trick
(the code below is not verified for syntax, since I was just about to shut down my pc, and I didn't wanted to restart VS.NET (lazy)
DetachedCriteria crit = DetachedCriteria.For<Contact>();
...
crit.CreateAlias ("Company", "c");
crit.AddOrder (Order.Asc("c.CompanyName"));
Something like that ?
At least, that is what I would try ...
