mrt based query with parameters

In the standalone designer I open an mrt fiile containing a connection to a sql database, with a query :

Code: Select all

select * from tblStatement where ID = @prmStatementID
When the query runs as a test, it works fine, but when the report is previewed, it reports the following error:

Code: Select all

Stimulsoft.Report.Design, Version = 2012.1.1300.0
System.Windows.Forms, Version = 2.0.0.0

If I provide an "expression" value to the Parameter 'object', this error goes away. Is that expected behavior.

However, if I then attempt from the C# code to apply the parameter:

Code: Select all

report["prmStatementID"] = 17745;
The change does not propogate to override that value I set in the expression (above).

Can you explain what I'm doing wrong...? How can I create an mrt that works in both the standalone designer, AND called from csharp ?

Thanks.

mrt based query with parameters

thanks to this post (( http://forum.stimulsoft.com/Default.aspx?g=posts&t=6086 )) .. I found my answer...or at least one that seems to get me there.

If I change my c# code to apply the parameter as such...

Code: Select all

            // Set some report parameters
            report.DataSources["DataGet"].Parameters["prmStatementID"].Value = id.ToString();
            report.DataSources["DataGet"].Parameters["prmStatementID"].ParameterValue = id;
then everything seems to work just fine. Setting JUST the ParameterValue as in the linked URL above did NOT work, but when I also changed the Value property, then it all clicked together nicely.

Any issues with this solution, Stimulsoft?

Hello.

Did you try to use this code before compilation?

Code: Select all

report["prmStatementID"] = 17745;
If yes, then it's wrong.
Before compiling yo should set

Code: Select all

report.DataSources["DataGet"].Parameters["prmStatementID"].Value
Thank you.

Did you ever get an answer on compiling?

The data in my report appears to be correct using the report["FromDate"] = new DateTime(2010,10,1); syntax but the parameter values which are shown in the report header don't reflect the value used.

Hello,

Please try to use the following code:

Code: Select all

report.Dictionary.DataSources["Name"].Parameters["FromDate"].Value = "\"10/1/2010\"";
Thank you.
