How pull in fields value from created parameter - ssrs-2012

I created a parameter [GroupID] that is used to query several datasets in my SSRS report. It is using the field [GroupID] from my GroupList_Rolling12 dataset. An example of [GroupID] is 77610N. When 77610N is selected, all of my datasets are correctly 'filtering' for this [GroupID].
I now need to create a text box that returns the [GroupName] of [GroupID]. In other words, when 77610N is selected from my GroupID parameter, I want the [GroupName] that is associated with the selected GroupID parameter to display.
I'm still very new to SSRS and cannot figure this out. I tried creating the expression =First(Fields!GroupName.Value, "GroupList_Rolling12") but that did not work since it simply returns the first value from the query.
I also tried =First(Parameters!GroupID.Value(0)) but this also did not work
I also tried this expression =Lookup(Fields!GroupID.Value, Fields!GroupID.Value, Fields!GroupName.Value, "GroupList_Rolling12")
)
Can you please help?

You can reference the parameter label directly like this
=Parameters!GroupID.Label
There is no need to put the index on the end (=Parameters!GroupID.Label(0)) unless your parameter is multi-value, in which case it would select the first selected entry.

SSRS Report Parameters Interactive

I have a report that requires 3 parameters, all 3 has q query to pre populate them using a dataset for each, so the under their properties the available values is selected with the query. Default were also set to use the same query. This work fine.
My problem is when the user of the report wanted to enter the values themselves rather than going into the list populated by the query. Users know the value that they wanted to enter so it's faster for them to enter rather than select. SSRS report seems not to give you the ability to enter if you have set the available values and default values for some reason. Is their a way to go around this please?
Many thanks.
There is one straight forward way to use comma separated multi value parameter rather than list where user enters input.
Below link explains in detail, but I am quite sure you do not want to stick to below solution.
https://www.mssqltips.com/sqlservertip/3479/how-to-use-a-multi-valued-comma-delimited-input-parameter-for-an-ssrs-report/
Another thing you could do is keep your multi value parameter as list as it is and create a text input parameter.
Now if user want to simply choose from list fair enough you will have to handle second parameter as null because user chose from list.
Then on your dataset check and apply filter as 2nd parameter value as not null.
Same goes if user does text input then multi value parameter as not null.

Crystal Report not filtering SQL records based on selection formula

unfortunately I'm not an expert of Crystal Report, so I'll post here my question hoping for any help about my issue.
I want to display inside my report the result of a filter on a SQL RecordSet; this RecordSet is looked up from an a single table, of which I want to show some fields of my SQL table, while the filter I want to apply is based on a field parameter (defined static) that I'm trying to set programmatically.
Here below I attached my code where I'm applying the record selection formula, I tried also hard-coding the value instead of passing it through a dropdown selection:
ReportDocument RPT_Doc = new ReportDocument();
RPT_Doc.Load(RPT_Path_Name, OpenReportMethod.OpenReportByDefault);
ApplyConnInfos(ref RPT_Doc);
RPT_Doc.SetParameterValue("data_riferimento", "20161001");
RPT_Doc.RecordSelectionFormula = "{viaggi.data_part_pre} = '20161001'";
crystalReportViewer1.ReportSource = RPT_Doc;
In the first image attached you can find the field parameter definition, while second image is the record selection formula I defined inside my report:
The report always shows all the records of my table (more than ten thousand rows), instead of displaying a filtered RecordSet. The odd thing is Preview function from Visual Studio works like a charm; it prompts the field value, once I confirm the value the viewer displays the report with the rows filtered as I expect..
What am I missing from report/C# program configuration to make the record selection work?
Thank you in advance for any suggestion you can give me :)

Ok, finally we got the solution to our issue.
We found the CrystalReportViewer object used to display generated reports has 2 different properties, SelectionFormula and ViewTimeSelectionFormula; both has default value set to empty string.
Below I attached the picture of .Designer.cs file with the 2 properties valued:
We commented those 2 properties and the selection formulas and field parameters applied through code / report designer worked again.

How to exclude values when passing multivalue parameters in Visual Studio?

I have an Action that opens another report and it passes a multivalue parameter. Is there a way to exclude for example, the first value of the multivalue parameter?
Assuming that you are using SQL Server for your queries.. when you pass the list of parameters into your subreport, I would take the parameter pass it to a splitstring function and then exclude the first row and then use the result in your where clause for your subreport parameter.
This way you have flexibility to exclude what ever row you want by passing the row number as a parameter as well.. just saying.. and you cal also check that you have more than one parameter selected before excluding it.. else you won't get a result back

How do I set an SSRS Parameter that doesn't have a value to something else?

I have an SSRs Report with a parameter that gets information from SQL. If it hasn't found anything, at the moment it is just empty. Is there anyway to set it such that if it's empty it will return a different value, say "Please Extend Date Ranges" and disable the parameter?
If you using it to fill it using the SQL and using it for only internal purposes then there is option to make the parameter internal and it will be hidden and it will does not prompt the user.
Make a change to the stored procedure or query that populates the parameter. Include some logic so that if no results are returned by the query you are using now, it adds a row with the default label you want.
But no, you can't disable the parameter dynamically, I don't believe.

ReportViewer - how to filter on Multi Value Parameter

I have a report that uses a Multi Value parameter. I have added this to the report and can specify the parameter values in code.
Now I want to filter the data on the report by the multiple value parameter. Eg, I pass in a list of account no's and I want to filter the data on the report so only records with the passed in account no's are shown.
In the tablix properties there is a filters option which looks like the place I need to set up the filters.
I have added a new one, selected the Account Number column on the report. The operator that seems relevant to me is the 'in' operator. So show records that a 'in' this list. However, If i select the 'in' filter the expression text box is disabled. Is this what im meant to use?
Found it:
You should filter on The name of the parameter rather than an expression.
eg:
[#CostCentres]
rather than:
=Parameters!CostCentres.Value
