Convert 2005 RDLC to 2008 using VS2010


Hi and thanks.


I'm getting an error on serveral reports that I built  in VWD2005 (express) using the reportviewer control.  Trying to edit the rdlc file in VS2010, VS2010 asks if i want to convert the file to RDLC 2008 format and I click ok.  When I build the site, I get this error (and of course also when the report is ran):


Error 1 The report definition is not valid.  Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition' which cannot be upgraded. C:\inetpub\wwwroot\mastercardlcm\Reports\WorkLists\OpenSRStatus.rdlc 1 


Here is my web.config concerning the RDLC assemblies, etc.

How can I pass a parameter into my report?


I looked all over the forums, spent about a day on it, found numerous people having similar problems passing a parameter, but all the solutions I found so far were partially incomplete or incompatible to my project. I tried using a few of the "solutions" and they generated exceptions. I'm using straight ASP.NET so far with no c#. Is there a way to do it without code behind?

If someone suggests a solution I would be very grateful! Laughing I'm certain that if you provide a complete working example that others in the future will be very grateful as well.

Here is what I have thus far:

I used studio to create an .ASPX web form, and I used the report wizard to create a .RLDC file on the .ASPX page.

When I execute it, it works! Beautiful... Now how do I pass it a parameter?

So this is what I have below (which works), but I want to pass in a single int32 parameter to the stored procedure usprptGetData in which it is based.

ssrs 2008 R2 - report parameter with no default set throws java script error

We have recently upgraded from SQL Server 2008 to SQL Server 2008 R2....I am experiencing a problem with my report parameters on my SSRS reports. It seems that my report parameters that I do not have a specified 'default' value throws a java script error when I try and run/render the report under R2.  As soon as I put a 'default' value on the report param, everything is fine.  However, that is not the behavior we need for our reports...the user needs to pick their selection. Can anyone shed some light on this, it seems to be an AJAX problem...I need to be able to have report parameters with a list of values, but no 'default' value on the parameter.

Displaying a Parameter Value in the report footer that corresponds with the parameterized data on ea

I've got a report that has only one parameter, it determines the department (or departments) to base the report on, the parameter is set to allow for multiple values. The report returns only on page per department, so the report could be anywhere from one to a hundred pages, one page per department. I've included a text box in the report footer that displays the report name and the parameter value, the expression looks like this: =Globals!ReportName & " For Department " & Parameters!Dept.Value(0)    I know that in this example the zero inside of the parenthesis of the parameter value is what is returning the actual value when the report is rendered, and I understand that the zero is value in the array of parameter values. What I'm looking to do is adapt this expression so that the parameter value rendered on each page corresponds with the data (departement) displayed on the specific page. So using the example of the data, if the user selected three departments in the parameter drop down, then each page that displayed the different department’s information would also display that departments name in the page footer text box. I'm thinking that each time a page is rendered that there is a group or global variable that can be called to provide this dynamically but I can't seem to find the information. Appreciate any help, Dan

Having problem accessing multi-choice parameter in SQL Query in Report.

Hi, I have a report with a multi-choice input parameter. My report contains a dataset that uses CHARINDEX on this multichoice parameter. The dataset query is in text, not in stored procedure. When I run the report I get "the charindex requires 2-3 arguments the reason being that the SQL is run as follows (You can see the multi-choice list screws up the string: exec sp_executesql N'Select test.Region [Region], test.Location [Location], nvarchar3 [Year], nvarchar4 [StatisticType], nvarchar5 [StatisticType2], ntext2 [Detail], float1 [Amount]   from [WSS_Content].[dbo].[AllUserData] UD   inner join [WSS_Content].[dbo].[AllLists] AL on AL.tp_ID = UD.tp_ListId and AL.tp_Title=''Statistics''   left outer join   (       Select UD.tp_id [ID],nvarchar1 [Region],     nvarchar3 [Location]   from [WSS_Content].[dbo].[AllUserData] UD   inner join [WSS_Content].[dbo].[AllLists] AL on AL.tp_ID = UD.tp_ListID and AL.tp_Title=''Regions''   where UD.tp_ListId = AL.tp_ID   and UD.tp_ListId = AL.tp_ID   and UD.tp_DeleteTransactionId = 0x0   and tp_IsCurrentVersion = 1   ) test on test.id = UD.int1   where UD.tp_ListId = AL.tp_ID   and UD.tp_ListId = AL.tp_ID   and UD.tp_DeleteTransactionId = 0x0   and tp_IsCurrentVersion = 1  &n

How to re-render report on parameter change?

I have a drill-down report with several levels. I added a parameter to allow me to collapse/expand all so I don't have to go through all the levels to open individually. This works but I have to set the collapse state on the param, then I have to click View Report button. I haven't found a way to tell report to re-render when a certain parameter changes so I don't have to click the view report button. Is it not possible?   Thanks!--ACG
