Hi,

When creating SSRS report, I'm adding a selection in my Data Contract Class, which the plan is to determine it will process a detail or a summary report. In the SSRS report it self, it will have 2 design, for detail and summary.

Question is, in my controller class, what should I write to read that result selection from contract class ?

In some blog or thread, I found some example of needed to method preRunModifyContract(). May I know it looks ? and how about the method main().

I used to put the report name and design in this main() method. Something like this:

        controller.parmReportName(ssrsReportStr(ItemSummaryReport,Empty));        controller.parmArgs(_args);        controller.startOperation();

But now what should the main method() need to be written, while we have preRunModifyContract().

Thanks.

Hi,

Sorry, for late reply. I change the way I create this report, by not using 2 different TempTable. So, actually it is not solved.

But the thread can be close, I guess.

Thanks

Hi,

Regarding to 2nd issue

Try the following:

1- Check the fields on the DataSet of the report for any duplications also the parameters if any were duplicated.

2- Try to create new report, add the dataset to be your query and copy designs from the old report

Thanks

Hi Ken,

I think this is another issue.

So is the report name error gone now when debugging or not?

Regarding the 2nd error, do you have two fields with the same name?

Thanks,

Probably it's because my RDP class. There are 2 temptable, which actually not too sure that is the way of doing it.

Why I can say this, because I realized my report data set missing 1 parameter: the checkbox for "isSummary" (btw this checkbox is newly added after I make sure the report is fine for just 1 Design and 1 temptable, for the "Details" only) but if I tried to restore will show error:

And I get the same message if I open Dataset property - Query.

Thanks.

Hi Ken,

I think you still need this line in the main method.

controller.parmReportName(ssrsReportStr(YourReport, Summary));

Then maybe preRun method will override the value. Give it a try please

Look at where the exception is thrown, e.g. by checking its StackTrace property. So far, all you know is that it something called inside startOperation().

My guess is that some logic requires a report name already selected before reaching preRunModifyContract(). Debugging will tell you more.

How to make my controller class read contract class ?

Hi,

Thanks, but unfortunately I'm hit run time error ->

Just to share, the way I call is just by creating output menu item and set to this controller class. If I understand correctly, all class should first call this main() method, am I right to say that ? Is there some method missing in this controller class, because looks like the report name has not been hit (have value).

Perhaps some other information I should share ? Sorry, this is my first time create something like this, so I don't know as well what important information I should tell earlier.

Thanks.

Hi Ken,

Just rename the variable to sth else. Or say reportName=... Without declaring it as it's already defined. Or do like i showed you

contract.Summary()?this.parmReportContract().parmReportName(ssrsReportStr(YourReport, Summary)) : this.parmReportContract().parmReportName(ssrsReportStr(yourReport, Detail));

Thanks,
