Executing SSRS using the 'label' field instead of 'value' field

Question

Hi,
We have in house custom SSRS reports built for our clients and each of those reports have a 'label' field and a 'value' field. Now the 'label' field is something that the client sees on the UI as a friendly name. When a client runs the report, it gets executed
against the 'value' field and so I was wondering if there was a way to tell SSRS to execute against 'label' field as oppose to 'value'.
Appreciate your response!
Thanks,

I found the solution!!! By design, SSRS will not convert Label to Values. You will need to write custom code to do this. You need to do the below
a) You need create an instance of
ReportingService2010
rs =
newReportingService2010();
b) Then you need to populate the ParameterValue[] array and populate the 'Name' and 'Value' (here the 'Value' is actually the Label that the client sees on the UI)
c) Assign the following
string report = "[report_path]";
bool forRendering = true;
string historyID = null;
DataSourceCredentials[] credentials = null;
ItemParameter[] parameters = null;
and then call parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials);
d) The above call gives you the Label-Value pair mappings within the "parameters" object and if you have cascading parameters, you will need to recursively call parameters = rs.GetItemParameters(report, historyID, forRendering, values, credentials); which
will give you the complete set of the Label-Value pair mapping.
e) You then iterate through the above collection and the get the Value for that Label and pass it on to SSRS
I have tested this internally on several reports and it seems to be working. I can now pass in the displayed values to our custom web services and the above steps take care of populating the Label-Value pair mapping and then calling SSRS with the actual
'Value'
