Fetching report parameter value [message #544080]

Hi,

Is there any way to fetch report parameter value?

For example, I have default parameter value in dataset, and I would like to fetch that value and show in column.

I tried with this:

myValue = params["Name"];

but doesn't work...

There's not going to be a simple way. The value you want isn't a direct attribute of the parameter, it's part of the report design. There's probably an API call that will fetch it - someone more experienced in that area can address this.

Is this a dataset parmeter or a report parameter.
myValue= params["Name"].value should work to retrieve the current report
parameter value. If you want the default value you could call the RE
API from script like :
var rr = reportContext.getReportRunnable();
var engine = rr.getReportEngine();
var tsk = engine.createGetParameterDefinitionTask( rr );
aaa = tsk.getDefaultValue("Name");
tsk.close();

Jason and Richard, thanks for your reply.

I would like if you could tell me one more thing:

how could I fetch some value in row during creation?

for example,
i know how to catch row value:

some_var = row["Name"];

now, how can I do this in reverse way:

example
row["Name"] = some_var;

Is this correct or...?

Regards,

It sounds like you want to replace the field value in that row with a different value. I'm not sure where that would be necessary. Do you really just want to display a different value on the final report? If you can explain what your full goal is for this question, people can have a better idea how to answer.

I have two datasets binded to two different tables:

dataset1 and
dataset2

When I show dataset1 on report in table, on tableCreate event, I am fetching some values.
Then, each of that values I want to bind in dataset2 to be default value in some dataset parameter.

Is that possible?

I'm still confused when you say you want to set the default parameter on dataset 2 based on data already retrieved from dataset 1 and used in table 1. BIRT prompts for all parameters at the same time.

Richard, sorry if my explanation is confusing...
I''ll simplify:

Can I onCreate event on table row change some row value?

for example:

onCreate event on table row I want to change my data value:

ex:
if (this.getRowData().getExpressionValue("row[WI_ID]") == 2851){
row["WI_ID"] = 2852;
}

so, on row create I want to change data value...

Regards,

I wouldn't do it there unless there's something else referencing that data valye. If you're just trying to change the amount that shows on the report, I would do that with the Map property.
