SetParameterValue has no effect.

[Former Member]

When I use reportDocument.SetParameterValue("parameterField", "value") in any report I do not have any problem. My problem is when there is a report that has some sub reports and I use the SetParameterValue to pass a value to a parameter in the main report, the SetParameterValue has no effect and the promport for parameters appear even the sub report has only linked parameters.

I do not use refresh at all.

Please help me to discard the parameters propmpt.

I fixed this problem by setting the parameter values to the report viewer not to the reportDocument. If I SetParameterValue to the ReportDocument to some parameters in the main report in a report has sub reports. the Enter Parameter Value dialog appears even the sub report has no any parameters.

I've found that SetDataSorce resets all the params

Set all your datasources first (including the subreports, if it applies) and then SetParameterValue
