Generate Your Dynamic Report Through Reporting Service

I have posted some articles on reporting service. Here is a sample project which will generate report dynamically. It is having an interface where you select the database in a DDL then a table or view from the selected DB and select some columns for details and group of the report. Then it will generate the report RDL and publish it to your report server. If you want to select from multiple tables with joining, you can do that also by giving your custom query.
Here are some setting which you will have to change to run the project like
string serverName = "localhost"; //The server where the report will be published.
string reportVirtualPath = "LocalReportServer"; //The virual directory path of the reportserver
string parentFolder = "QuoteReports"; //The folder where the reports will be published.
Here i am using some AppSettings val in web.config. Change those according your local settings. But in "MasterConStr" the 'Initial Catalog' value should be 'master' because this connection string is used for fetching data about DBs.
Add the web reference of the reporting service to your ptoject. You may have to change the "RSLocal.ReportService2005" AppSettings value.
Here is the link of the project http://w17.easy-share.com/1700907813.html
Here i am using sql express repoting service and my report server and database is in dame machine. If you have the Report server installed in other machine than the Database you may have some problem with the DataSource. For that pls refer to my other post Use stored credential for report created by c# code.

Reporting service: Dynamic Toggle Group

In my current project i have to use Reporting Service 2005 for generating some reports. It was the first time for me to RS. The report was showing some group on Year >> Month >> Day. The report was drill down one. I had to show the current month's days open i.e when the user open the report which is decending sorted with year,month,day will show the report with current mont's days expanded. All other years and month will remain collapsed.
For that i added two parameter to my report through
Report Layout (Designer)-> Report (Menu) -> Report Parameters(sub menu).
The parameters are showYear of type int and showMonth of type int.
Default value for showYear, i selected "non-queried" and in the textbox wrote =Year(Today)
and same for showMonth with TB value =Month(Today) so that the default value is set to the current month and year.
Now i edit the group showing the month and in the visibility tab i set "Initial Visibility" expression to "=IIF(Parameters!showYear.Value=Fields!Year.Value,false,true)", so that if the yeay is equals to current year then it will stay initially visible. And for day i set expression to "=IIF(Parameters!showYear.Value=Fields!Year.Value,IIF(Parameters!showMonth.Value=Fields!Month.Value, false,true),false)", so that if the month and year is euals to current then it will be stay initially visible (i kept the "Visibility can be toogled by another report item" section as it was.).
Now when i preview the report i found everything is running fine. By default it is expanding current year and month and if i put some other value in the report changing textbox it is expanding corresponding record. But the "+" and "-" signgs for toogle for those initially expanded is showing opposite i.e. "+" even when initially it is expanded and "-" when clicked to collapse.
Why this is happening? After searching various properies for the report and its item i got the "InitialToogleState" property of the textbox which by default is collapsed. Then i set this property to expression so that it is "Collapsed" and "Expanded" properly to show "+" and "-" sign respectively.
I set the year textbox's (TB which is responsible for toggle in year group row) InitialToogleState property to "=IIF(Parameters!showYear.Value=Fields!Year.Value,true,false)" and for month's one "=IIF(Parameters!showYear.Value=Fields!Year.Value,IIF(Parameters!showMonth.Value=Fields!Month.Value, true,false),true)" . Then i saw the result was as desired.
We can hide the Parameter Promt in the report viewer by ShowParameterPrompts="False" in the reportviewer control and send the parameter by querystring as 'showYear=2004&showMonth=5' .
Some points to note:
1) "InitialToogleState" property is boolean. "Collapsed" indicates false and "Expanded" true
2) "Initial Visibility" is set to month and day rows where as "InitialToogleState" is set for year and month TB.
