HI,

The question:
i would like have a list of "items" (Combobox or other object)  always visible and on selecting one or more item from the list i would like to see a report of data .What matter is that the second report be displayed just after selecting one or more items from the combobox ( or other object).
This is a scenario very close to a Drilldown one or a Master/details one, but in my scenario there is no Database relathionship between items and the report i want to be displayed. Lets say that the items are the names of  some tables on DB. The user  selects one or more of this table from combo (or other object) and a the report with data from this table is shown. This report has own parameters and one or more crostables to analyze the data.
If it is possible to keep on the same report (Area) the combobox and the the related data-report it will be  perfect. But also having the list and  the report in two separated area could be fine. The matter is that the list be always visible.

The History:
Working  with a crossTable: no problem to bind it to a datasourceObject from my DataLayer.So i have my data grouped and crossed as expected.
Next i added some parameter at design time (report.reportParameters object), here the problem. Using parameter (multivalues) the crossTable is rendered consequently(record are filtered) but not total and grand Total. The total fields show always the total calculated  at the time i  have bounded the datasource. 
In other words once you change parameter, the crosstab is re-rendered but not re-calculated.

To solve this i tougth to re-bind the datasource every time the parameters are modified. That is:

1- getting my data record list  from my DataLayer lets call it listDL
2- passing listDL to a businees object list (lest call it listBO) to work with data in memory
3- populate the parameters collections assigning listBO as datasource
4- executing LINQ queries on listBO using the parameters values.
5- rebind crossaTable datasource to listBO.

The report i am working on is an aggregate report, it shows several tables, them are different views on the same datasource.
That is: different LINQ queries on listBO . This is why i use ListBO: i don't  want call several time my DataLayer and i prefer to use ObjectDataSource then SqlDatasource planning to use this code with our MVVM model.

This was the idea and i started this way:
the first 3 steps are executed in the report constructor
the last 2 steps are executed in NeedDataSource routine
All seems working fine but :
at step 1 i have to pass a parameter (table name) at the method calling my DataLayer to retrieve the set of Data i needs.
let say this parameter is the name of a table Database.
The user have to be make able to choose table's name  from a list . The list of tables is retrieved by a call to  DataLayer .
The question is: where and how i can do this?
I can't add another parameter (for table name) ad design time because i can catch its value just in NeedDataSource routine, but the this value have to be cathced at step 1  (in the constructor ).
The only way i see is to pass the parameter to the constructor, but how can i do this?
The closest thing i could think is something like a subReport, but to manage a subReport with own Parameters UI seems too complex to me.
A easier solution could be to create a report for choosing the tables and then navigate at the crosstable report passing the choosen parameter.But i whould like to select the tables without navigate trought the windows.( User should select table very frequently)

I have no idea about to accomplish this


Thanks for reading

Hi,

I am using Telerik Reporting and my client wants column sorting. The scenario is that when the report loads completely he  must be able to click on a on any particular column title and the data sorts accordingly and after that sends the report to printer. Any help would be greatly appreciated.

I want to custom button "Preview" and others when I use ReportParameters in Report.Can you help me to resolve! Thank you!

In the calling application I am able to set the datasource of my subreport with:

 

Dim subRepItem2 As Telerik.Reporting.SubReport = TryCast(TryCast(ReportViewer1.Report, rptRemit).Items.Find("rptSubRemitTransactions", True)(0), Telerik.Reporting.SubReport)

 

subRepItem2.ReportSource.DataSource = ReportsDAL.RemitByTransDateHistory(

Me.txtStartingDate.SelectedDate)

I then try to customize the contents of a textbox based on the same report parameter but I get an error:

 

 

Dim txtbox As Telerik.Reporting.TextBox = TryCast(subRepItem2.Items.Find("txtTotalSince", True)(0), Telerik.Reporting.TextBox)

 

txtbox.Value =

"Total Since " & Me.txtStartingDate.SelectedDate.ToString

The error is:
System.IndexOutOfRangeException: Index was outside the bounds of the array.

Help please!

 

Hi

I am trying to pass an int array from SilverLight Codebhind throigh ReportParameters to the Report. I am getting the follwoing error when i run the app.
"An error has occured while processing Report 'Report2'
An error has occured while resolving 'Objectdatasource1 datasource: Object must implement IConvertible'".

The fllowing is the xaml codebhind


The following is the method the object data source is bound to using dataMember propery


Please help me how do i do it.

Thanks in advance

Is the Telerik Reporting component compatible with ASP.NET 2.0/Visual Studio 2005?

>>>>>>>>>i not understand! Admin can you help me? thanks you very much!

When I move my application to a different server I get the 'Report is unavailable or sessions expired' error I've read about.  The ASP.NET report viewer on a webpage on the same machine works fine.  Since it works on my other servers, this must be machine specific and it's different because it's server 2008, IIS 7.5.
I'm looking at the Session State page and the Session State Mode is set to 'In process'  This should be fine right?  It's on a dedicated server.  What else should I look for?
