I have a report with a multi-valued parameter on it. I'm looking to output the selected values which is accomplished with Join(Parameters!State.Label,",")
Every solution I've found on the web indicates I should use something like the following to detect when the (Select All) "value" is selected.
E.g. expression for the text box on the header should be:
="State: " & IIF(countrows("prc_prompt_state").Equals(Parameters!State.Count),"(All)",join(Parameters!State.Label,","))
CountRows() tells me the total number of parameters available, e.g. 8 states in Australia. Parameters!State.Count is supposed to tell me how many are actually selected by the user. However this always reports the full value (8 in this case) regardless of how many are selected. This is in agreement with the official docs (https://technet.microsoft.com/en-us/library/aa337293(v=sql.100).aspx), but NOT in agreement with every single search result I come up with on how to solve this problem.
So how can I rewrite this expression so I can find out when (Select All) is/isn't checked? I'm using report builder 3, which I believe is based on the 2008 edition - we deploy to Azure, but I haven't got that far yet.
Examples of questions whose answers seem to be wrong:
Displaying Multi-Value Parameters
SSRS: Can I know if user selected "ALL" in multivalued param?
This is old, but google found it for me, and then I figured out an answer on my own that worked. (I was using a list of users.)
I created a separate dataset that returns a count of all available options in the default parameter lookup (username). Then, I assigned that as a default value to an internal parameter. (UserCount) This worked as a text expression:
=Microsoft.VisualBasic.Interaction.IIF(Parameters!username.Count = Parameters!UserCount.Value, "All Selected", Microsoft.VisualBasic.Strings.JOIN(Parameters!username.Value, ", "))

I hope this is not a stupid question, but I have searched everywhere and have tried everything.
I have a dashboard and would like to group the tablix (The dashboard is inside the tablix) by one of the Parameters (Consultant). There are a few Data sets(queries) in the report and all of the Parameters are filtered with IN in the where clause.
The problem I have is that when I go to the row group properties and select the Parameter in the expression, then it automatically adds a (0) at the end. If I take the (0) away then I get the error message:
the group expression used in grouping 'Group1' returned a data type
that is not valid
I know the (0) is for getting the first value, but I am using Multi-valued Parameters.
I have tried one thing I found, but unfortunately it didn't work for me (SSRS Group By Parameter).
Edited:
This is to show you that there are multiple Data Sets(Queries) in this report
I have the dashboard in a tablix so that I can group for each Consultant, so when I choose 3 Consultant, I get 3 dashboards.
Expression used:
Then I get this error:
I have also tried using the CStr, but also no luck.
When I add the Parameter in any expression box it automatically put the (0) as below:
But then it doesn't use the parameter as I get an #Error where is should be the Consultant name.
I also used this option for page break but end up with graphs below each other:
This is what happens to the Charts(Sub Reports)
To give you an idea how the dashboard should look for each Consultant.
Regarding the other question I saw. I just tried exactly as they said but also no luck
I hope this isn't too much information. Just trying to help you help me.
Thank you!
UPDATE:
Parameter Properties:
Have you tried using the list tool to separate the sub reports by Consultant? A list acts like a container and will create whatever is inside for your grouping. You should also be able to apply a parameter to the list for filtering.
I am using stored procedure in mssql as backend, vb.net as frontend (just info).
There are a lot of records in the database and I am printing in crystal reports.
Now I want to filter the records from crystal report and not by adding a new parameter to procedure or changing database structure or else.
For now,Say there are columns : Name , Amount.
I want to put filter in amount like only display records whose amount above 100 or something. So other records with less than 100 should not be displayed.
This filter will be passed by the user so it'll be random.
I can't find a proper answer on internet. Might be a duplicate question, if so please post the link of the question if it is duplicated.!
Thanx anyways...!
In general the idea is to:
Create the parameter (user choose what will be the input/value) - link
Set filters, what values should be displayed in regards to parameter - link
On right side there is a DataExplorer window, where You need to add a Parameter (define his name, what question will be shown to user and what type the param will be / what values can be set inside).
Once done, You can jump to Data tab of a report, click Interactive Filter and specify which column must fit what condition with what value = Parameter (that one user will enter in Report).
Example: I will create AmountParam, with message "What should be the minimum amount?". Type will be set to Integer. Going to Report->Data->Interactive Filter, choose Amount as a Column, AmountParam as a Parameter and set condition Greater then (>).
I have a report in ACCESS that Is based on a query of a table populated by a form with an Option group. ( to try to explain this better - Table is inspector qualifications, the query pulls all of the qualifications for the inspector, the qualifications are selected via option group on a form that populates the fields of the inspector qualification table.) Of course, the choices are stored as numeric values, "1, 2, 3 or 4" in the table, but 4 actually designates a N/A or NONE. Since everything is already built out this way, I am trying to write a code that will run when the report is generated (or opened,) that will take the "4" value entered (if the field equals that) and change it to a Null value /blank in the report - not in the query or table. I still want this report to generate everything else as is - show all records - just change the value if that particular option is the one shown in that field for that particular record.
Anyone know of a good way to do this? Any help would be GREATLY appreciated!!!!
You would just place an 'IIF' in the query that tests for the value you want to change, then either changes it to something else, or retains the original value. The below will test field 'Nbr1' for the presence of a 4, and if found, change it to 'N/A', otherwise it stays the same.
Note! You will need to change the control source in the report to reflect the name you provide (i.e. 'MyChange') because you can't keep the original name.
SELECT Table1.ID, Table1.EMPID, Table1.TestResult,
IIf([Nbr1]=4,"N/A",[Nbr1]) AS MyChange, Table1.Nbr2
FROM Table1;
I got the Tumbleweed badge for this question.... :)
I've moved on a little from the original question but still looking at using internal/hidden parameters, this time passing to another report which runs a stored procedure (which sends an email).
The main report (report A) has a parameter called StudentCourses (originally called ReportParameter1) which I have tried both as Hidden or Internal, and currently has ticked Allow blank value and Allow multiple values.
(Its default value is a field from the result of a query, which shows the courses a student is enrolled on).
Action for my textbox no longer goes to URL (to open PHP form) but now uses Go to report to call report B. Under action options I've added two parameters; StudNetworkID and StudCourses. The number of courses can vary from 2 to 5.
The new report (report B) has two parameters also called StudNetworkID and StudCourses; both are Hidden and StudCourses has ticked Allow blank value. [All parameters are text, btw].
If Report A StudCourses is set to =Parameters!StudentCourses.Value(0) then the first course is shown on Report B. So far so good.
If Report B StudCourses is set to Allow multiple values, then Report B shows #Error and the Warning description given is "[rsInvalidExpressionDataType] The Value expression used in textrun ‘Textbox3.Paragraphs[0].TextRuns[0]’ returned a data type that is not valid."
If Report B StudCourses is set to NOT Allow multiple values and Report A StudCourses value is set to [#StudentCourses] then Report B shows the text "[#StudentCourses]".
If Report B StudCourses is set to Allow multiple values again, then I get the same invalid data type error as before.
Having turned off Allow multiple values on Report B to avoid the #Error issue...
Setting Report A StudCourses to =Parameters!StudentCourses.Value(0) & Parameters!StudentCourses.Value(1) then Report B shows course 1 and course 2 on one line. OK so far.
However, setting Report A StudCourses to =Parameters!StudentCourses.Value(0) & Parameters!StudentCourses.Value(1) & Parameters!StudentCourses.Value(2) gives me a runtime error that the Index was outside the bounds of the array (because there are currently only two courses). On clicking the textbox, Report B just says "The 'StudCourses' parameter is missing a value".
OK...
I turned off Allow multiple values on Report A StudentCourses parameter (the one holding the result from the query) and for the Go to report parameter StudCourses I added the other values, so eventually had value(0) to value(4), the result was interesting. For each parameter value used it gave me a letter from the first course on Report B. Hence when I included up to value(4) it gave me the first five letters of course one!
Yep, ok, this is because it is no longer reading multiple values and so specifying a number just returns the letter from that position.
SO...
How do I allow for up to 5 courses to be passed over???
What follows below is the original question
I have a small report designed in Visual Studio that displays courses that a student is enrolled on. The number of courses can vary from 2 to 5, depending on the student.
Also on the report is a text box, which when clicked will action a url to open a PHP form.
I have worked out how to pass the user id to this PHP form but, if possible, I would also like to pass the course titles.
If I use internal report parameters* I can add these to the url, like this:
="http://myurl/webform.php?param=" & Mid(User!UserID,InStrRev(User!UserID,"\")+1)
& Parameters!ReportParameter1.Value(0)
& Parameters!ReportParameter1.Value(1)
& Parameters!ReportParameter1.Value(2)
& Parameters!ReportParameter1.Value(3)
& Parameters!ReportParameter1.Value(4)
but unfortunately I get the runtime error "The Hyperlink expression for the text box 'Textbox7' contains an error: Index was outside the bounds of the array."
If I just put the first two report parameters it works fine.
I tried using parameter count, e.g. iif(Parameters!ReportParameter1.Count > 2, Parameters!ReportParameter1.Value(2), " "), but I still get the same error.
Please can someone show me how to get around this runtime error, or suggest another way to do this?
Thanks
PS * Report Parameters set up as Text, Allow blank value, Allow multiple values, Internal, Available Values = None, Default Values = Get values from a query; Value field = course title.
I'm working on a report in Reporting Services and I can't figure out why I'm having trouble with Non-queried report parameters.
I'm trying to get the current year and have tried:
=YEAR(TODAY())
=DATEPART("yyyy",TODAY())
I have also tried TODAY instead of TODAY()
All of these seem to break the Year dropdown on my report. I thought if something was wrong it would just not get the correct default... but nope, it breaks the whole field.
Any thoughts? articles?
UPDATE:
Wait, wait, wait... the weirdest thing. The Year parameter is the second parameter of this report. And its grayed out (with no value) UNTIL I select the first parameter (im my case "category"). Am I somehow telling the Year param to do this? or does SSRS 2005 process the params in order? I don't think I ever noticed this before.
UPDATE 2:
Please see all comments
=DateTime.Today.Year
should work as well.
Edit: Bruno - i have the same behavior as you are seeing. I created a sample report with a string first parameter with no default value, and a string 2nd parameter with a default of =DateTime.Today.Year. When I have the one with the default as the 2nd parameter in the order, it shows up empty and disabled.
I was able to fix this problem 2 ways: first by adding a default of =String.Empty to my first parameter, and the second way was to just change the order of the parameters.
Not sure if this behavior is by design or a bug - but like you said, I hadn't noticed it either until today when you pointed it out in your question.
Try:
=Year(Now)
I'm not sure if this is what you need, but it worked for me. I used it to form a date string so I used =Year(Now).ToString().
SSRS does process the report parameters in order - order can be important if you have dependencies between your parameters.
From MSDN: "Parameter order is
important when you have cascading
parameters, or when you want to show
users the default value for one
parameter before they choose values
for other parameters."
So, it will always wait until you have a default value for your first parameter or you enter the first parameter's value, before it processes the next one, and so on.

I found the by making sure that ALL of my parameters had at least some default value, then you will not experience they greyed out datetime picker. So, every parameter before your datetime paremeter in order needs to have a (default) value or it will not work.
Def due to order of evaluation of parameters.
Simple workaround ; in the parameters tab you can change the order of the parameters - this will move the date pickers to the top of the list and are then enabled straight away, on my server at least.
Someone raised the issue of basing a date filter on a queried default value - if you do this, you will notice a very annoying knock-on effect of getting screen refresh any time the dates get changed, before you have a chance to requery the reports.
