[rajesh]

I am using Telerik Reporting Controls in my application.I have a requirement where i will be having more than one table in a dataset.
i need to bind the data of first table to header and second table data to body and third table data to footer.

can it be possible to do like that.if it is then can you please let me know regarding this.

Thanks & Regards,

Rajesh

Hello rajesh,

Telerik Reporting supports data-bound items in the report header/footer sections, group header/footer sections, and the detail section of a report. Data-bound items in the page header/footer sections are not supported, because it does not make sense. You can bind to more than one DataTable from a DataSet, of course.

You can visit our online documentation to familiarize yourself with the different report sections and the supported data binding. Check our online examples too, to see if any of them does something similar to what you are trying to accomplish.

We are sorry that we can not be more helpful, but since we do not know your specific requirements, this is the best we can tell you so far. If you have more specific questions regarding Telerik Reporting, please, do not hesitate to ask.

Greetings,

I was just reading your posts to find out myself how to bind to more then one table in a Dataset and from your answer you stated that
"You can bind to more than one DataTable from a DataSet, of course."

You also linked to the data binding page and this is what that say's.  Unless I am missing something this is conflicting information.

"Telerik Reporting can be bound to a single table only. If your DataSource contains more tables, you can bind a separate report to it and take advantage of a subreport item or use table item to directly show data in main report."

Can you tell me what is correct?  I am not seeing how you can use fields from more then one table using the Report wizard and a dataset with more then one table.

Thanks,
Dave

Hi Dave,

The explanation from my colleague's post only explains that this is possible, while the information in the documentation explains how to bind to more DataTables - via table/crosstab or subreport items. The wizard allows you to bind to a single DataTable and as explained - this is by design.

How would you access a particular table at design time?  I'm using WCF webservices.  I need the codebehind code, and what settings or extra code I would need in the actual report itself.  I have multiple tables, but I can't seem to figure out how to access a particular table at run time.  There must be some code to set the datasource to a particular table, but I've tried many things including:

report.DataSource = dataset.Tables[0];

My fields are coming up blank.  But, with a ONE table dataset, it works perfectly.



Thanks.

Hello Chris,

If you prefer to design the report in Visual Studio designer with multiple tables you should use as many DataSource components as the number of the required tables. As I see from your explanation you are using  a DataSet but you do not show how the tables are filled with data and where and when this happen in your code.

We highly recommend you to open support ticket in order to send us a sample project demonstrating the issue.

I figured it out, thanks.  It was the fact that I had to bind a datatable to each object, such as a table, etc.  I can't use two different datasources for the main report, only one, but the objects such as subreport, table have to be in the detail section, not in the main page area, etc.

Hi Telerik Team

I want to make one stock report which contains data from 3 tables(sql) as given below. I want to show(select) all Products from 3 Tables, but products from “Purchase_Table” and  “Sale_Table”  should be between the user mentioned date (E.g.: 01-Jan-2013 to 01-March-2013, Date column(Filed) not mentioned in following Sales and Purchase Table but it is there). All Products from 3 tables should be grouped together according to their Product ID as given below(Stock Report).

1. Stock_Table
Product_ID	Product_Name	Opening_Stock	Current_Stock	Unit_Price	Total_Cost
101	Monitor	20	10	7200	72000

101	Monitor	10	7500	75000	3000
102	Keyboard	3	2200	6600	600
105	Scanner	10	5000	50000	5000
107	CD ROM	15	2300	34500	3000

Stock Reort
Pro ID	Product Name	Opening		Purchase		Sale		Closing
		QTY	Amount	QTY	Amount	QTY	Amount	QTY	Amount
101	Monitor	20	144000			10	75000	10	72000

Hope I will get solution soon, Thanks in advance...

Your scenario is actually pretty simple. You should JOIN the 3 tables, add WHERE clause for the dates and bind the data-source to a table. 
Most of the demos show how to work with parameters: http://demos.telerik.com/reporting/home.aspx , take a look at them and you should be able to do your report.

Hi Hadib Ahmabi,
God bless you,
I already used WHERE clause in my code snippette, but it only returns a product(s) which is stored on each 3 table). According to my table data mentioned above, when using WHERE clause it only returns 2 Products that is, 105, 107(Product ID is mentioned here). I want to Show detail of all products from Stock Table whether it is Available on other two tables or not. If it is available on other two table I need to merge these products with products from stock table according to user mentioned period (Date). Note that there is no date field in stock table. Just refer my table diagram given above.

[Hadib Ahmabi]

That's because you are making INNER JOIN. Try with OUTER JOIN.
LEFT OUTER JOIN between Stock Table and the other table should be the right one. 
See http://en.wikipedia.org/wiki/Join_(SQL)

You can bind to more than one DataTable from a DataSet, of course.

HOW?

[VEERANNA]

Hi ,

     I am using Qt RPT tool for making report for my qt application...my problem is that i have two tables for making report in single page ....how to do please explain?

 

[VEERANNA]

QTRPT supports sub report?

[Wayne]

Missing something. Binding DataSets at runtime with many tables to Reporting. I see we are told to look at the demos but the demos have no sample code to work\learn from.

Hello Wayne,

I will post below a reply from support ticket 1163463 that you opened for the same question:

"You can use a DataSet in Reporting with the help of the ObjectDataSource component. Sample code is available in How to: Bind to a DataSet. Since the report is rendered on the server in a client-server environment, keep in mind that the data has to be available on the server."

Katia
