SSRS Multi Value Parameter. Check whether "Select All" is selected - reporting-services

I have a multi value parameter in my SSRS Report. I want to find out whether (Select All) is checked in that parameter.
In other words, whether all the values in the parameter are checked or only some values are checked.
Is it possible?
I am able to find out number of selected values through Parameters!Parameter.Count. Is there a way to find out total of items in that parameter?

In case anyone is still having issues doing this, I just coded this easy fix.
=IIF(COUNTROWS("dataset").Equals(Parameters!parameter.Count),"it is equal","this is not equal")

For the specific use-case of showing the selected filter on your report in a textbox, here's the expression that will show "All" if "(Select All)" is selected, otherwise it will show all the selected values as a comma-separated list:
=IIF(
Parameters!YourMultivalueParam.Count = countrows("YourDataset"),
"All",
Join(Parameters!YourMultivalueParam.Label,", ")
)
(split onto multiple lines for readability)
countrows reference: https://technet.microsoft.com/en-us/library/dd255215.aspx
Credit to other answers, just want to extend them for this common scenario.

Your approach sounds good: I would make the options for the parameter come from a dataset.
Then you can use =COUNTROWS("DataSetName") to return the total number of options for your parameter and compare this with Parameters!*Parameter*.Count as you suggest.

I also faced this problem and I solved it this way.
I have one multivalued parameter named "Carrier". Then I have added one parameter "CarrierHidden" which is same as "Carrier" only thing is I made its Visibility as Hidden.
="Carrier=" & Switch(Parameters!CarrierHidden.Count = Parameters!Carrier.Count, "All",
Parameters!Carrier.Count > 1 And Parameters!CarrierHidden.Count > Parameters!Carrier.Count, "Multi",
Parameters!Carrier.Count = 1, Parameters!Carrier.Label(0))

The easy way will be to count the number of the selected parameters and compare them to the dataset
=IIF(Parameters!company_number.Count = CountRows("Dataset1"), True, False)

The problem is if you're trying to pull something for another data set then cross referencing the row count in another dataset won't work. You will have to go with what the previous post states. Create an internal parameter of the exact type and assign the default value to the entire dataset. That way you have the max count of the rows since the hidden parameter.count = rowscount. That way you can use it within another dataset also provided that dataset is AFTER the first one is populated.

According to Microsoft's SSRS help search:
=Parameters!<ParameterName>.Count
Returns the integer value 1. For a single-value parameter, the count is always 1.
I verified this does indeed work, check the integer returned for the built-in parameter count field.
Allow multiple values on a parameter selection. Checking the value of the above field will let you know how many values the user actually chose.
In my situation, I allow multiple values on company number. This gives users the ability to choose one company to report on or several at once. Per client request, if they choose more than one, display data horizontally. If only one company is chosen in the parameter list, show the data vertically and hide the other tablix.
So my visibility show or hide expression looks like this in the one tablix:
=IIF(Parameters!company_number.Count > 1, True, False)
and like this in the other:
=IIF(Parameters!company_number.Count = 1,True,False)

Enable Selection of only two values in SSRS multiple select parameter

I have a SSRS report in which i have a parameter which comes in a dropdown it is a multiselect parameter, now i want that at most user should be able to select only two values from the dropdown.
Although you can't stop the user from selecting more than two values, you can keep the report from being shown if they do. First, I created a red-text textbox at the top of my report that holds an error message. Something like:
You selected more than two values for ReportParameter1, try again...
Then, I set the visibility of this message with an expression (for hidden) set to =(Parameters!ReportParameter1.Count<=2). Now this error will show only when the user has selected more than two parameters.
I then hide the content of my report with a visibility expression of =(Parameters!ReportParameter1.Count>2). Note that you can simply put all your content in a rectangle and then hide the rectangle.
If your user selects more than two parameters, only the red error message is shown. If they select two or less, everything looks normal. I would also write your stored procedure in a way so that if a user selects too many values for the parameter, it won't return any data.
This is not possible. A multi-select parameter is that and just that: a parameter that lets you select multiple values.
If you will always only have two values that need selecting, the easiest way of implementing this would be to have two single value parameters labelled as Value 1 and Value 2 which are then both referenced in your report query.
There are workarounds as suggested by #Kyle Williamson in his answer, but there is no exact answer possible as this facility is not present in SSRS

SSRS - Multiple Tablix Filters Based on Mutiple Parameter Values

I have an SSRS Report parameter set up with 3 different values ("Paid", "Denied" and "Open"). I want to set a tablix filter up so when the user selects one of the parameters, and a condition in the data is met, that row is returned. I want to give the user the option to select all there parameter values.
When I use the following Expression into the Tablix filter(Paid), it works correctly:
=IIf(Parameters!ClaimStatus.Value(0) = "Paid"
and Fields!TotalPaid.Value > "0"
, "Include"
, "Exclude")
If I try adding an additional filter(Denied) with the following Expression, neither filters work:
=IIf(Parameters!ClaimStatus.Value(0) = "Denied"
and Fields!Denied.Value > "0"
, "Include"
, "Exclude")
Is it possible to pass multiple parameters into a Tablix Filter? I've searched all day with no luck. Any help would be greatly appreciated. Thanks.
You should set up the filter to check the values in teh DataSet are 'IN' the multi-select parameter
In this example my DataSet has a field called Status which could be Open, Paid or Denied.
I also have a multi-select parameter as you describe above called ClaimStatus.
Using the IN operator makes the filter look for instances where Status is in the list of ClaimStatuses selected. Note the default when you add the ClaimStatus parmater as an expression is to add a (0) on the end. Remove this
When this runs and I select Paid and Open, only the Paid an open records are returned in the table that has the results filtered.
Hopefully this will work for you. Let me know if I can assist further.

Using optional multi-value textbox as dataset filter

I have a report which returns list of product names and other product specs. This report currently has different search options. My users now also want to be able to search by product number by putting in multiple product numbers.
How can I add a filter by product number which is an optional multi-value textbox?
I have tried to add a multi-value textbox. The report doesn't seem to work when no values are entered. If I put one or more product number in the text box, it seems to work fine. Is there a way I can tell the report doesn't filter on the Null value parameters? Or any other idea to work with optional multi-value parameters?
Here is the setting for my multi-value textbox
Name = ProductNumber
Prompt = Product Number
Data Type = Text
Allow Blank Value (checked)
Allow Null value (not checked)
Allow Multiple Values (checked)
Here is the data set filter
Expression = [ProductNumber]
Operator = In
Value = [#ProductNumber]
Thanks
TL
I think you should trick the dataset filter by:
Expression should check to see if the parameter is blank and if so give expression a 1 else the field.
Value should do the same check and if parameter is blank set value to 1 else set it to the parameter.
But keep your operator.
Alternatively you could do this similarly in the SQL and with more flexibility and performance.
So as you've seen in your own testing, at least one value must be selected with multi-value parameters. You can't set Allow null value to true at design time and if you run a report without selecting any values it will throw an error message.
So you can't really have a report where users can run it with no values selected.
Taking a step back, what you're trying to achieve when ignoring the parameter is to include all Product Numbers by default. So why don't you set the parameter to have a default value of all Product Numbers selected? That way, users can just ignore and leave them all ticked if they don't want to filter by Product Numbers. Seems like a good workaround to me.
To do this, set the default value for the parameter using the same dataset that populates it:
All Product Numbers are now selected and users only need to take action if they want a subset of these returned.

Adding optional filter in SSRS 2008

I am trying to add an optional filter on a text field in a report. I have tried setting it up in the dataset but it treats it as a required filter so if it is not populated, no results are returned. It needs to use the Like operator. Any advice?
As I was typing out a work-around to this problem, I realized an incredibly easy solution (now that I understand better how it works).
Here's what I did:
Since Hong pointed out that all filter conditions must be met, I reversed my thinking. I moved my existing "IN" filters to the query and fed the parameter directly to the query. Then I created by "LIKE" text filter on the report which a default value of "*" so it would immediately return everything.
Here's what I could've done:
Just the last part. Added the "LIKE" filter with a default value of "*" so it immediately returned everything.
I also agree that most of the time it's best to send the params back to SQL. Since that's not what the OP is asking, here is the best option I have found for doing this. And it is actually quite simple.
Add your parameter with the appropriate data type. Let's use the
example of a "City" in this case (a text/string field).
Check "Allow Nulls" on the parameter.
Add a filter to either a tablix, table or dataset.
In the expression, select the field you want to filter on. Select the appropriate operator, in my example of a data set with Cities, in the Value put in this:
=IIF((Parameters!City.Value Is Nothing), Fields!City.Value, Parameters!City.Value)
I don't think you can make an optional filter in DataSet Properties/Filters, adding filters there means returning results that match ALL filter contiditions, so it is "AND" logical relation among all filters, not "OR".
My sugguestion is to use filter in query designer of the dataset, where you can define "OR" relations to filter out data. For instance: Your_Text_Field="SomeValue" OR Your_Text_Field is Empty.
Although I agree that most of the time it is best to send the parameters back to the stored procedure or data layer to reduce the amount of data returned, I have a case where it is just as easy to do the parameter handling in the RDL file via a filter. Due to this unique situation I found this solution which gives you a way to create an Optional filter in the RDL file.
http://www.andrewshough.com/development/sqlserver/ssrs/optional-filter-in-ssrs/
It is a great blog post with easy step by step instructions on how to create an optional filter.
Please Note: This is NOT my blog but I though this solution was great for what I needed and I hope it helps someone else when they google for "optional filter in SSRS" like I did.
I found a post which solved my problem setting the filter for a report-consumer to a) all multivalue fields being selected so the user b) could specify his/her selection if necessary.

In reports when we want to default the multivalue parameter to 'Select All' following are the steps.
Open the Report parameter window from the Report menu.
Select the Report parameter from the left handside of the window.
Select 'Multi-value' checkbox and appropriate 'Available values'.
Under default values select 'From Query' radio button'.
Select the appropriate 'Dataset'.
Select appropriate 'Value Field'.
Save the Report and select Preview Tab. You will find all the items selected in the multivalue >parameter list and the result displayed for all the selected items.

(The Post came up in the comments quite in the middle.)
You can accomplish this by using an expression on the dataset filter.

SSRS: Can I know if user selected "ALL" in multivalued param?

Customer wants me to repeat the parameter values in the page header of the report. But if they just choose "Select All" on a multi-valued parameter, they want the text "Any" listed.
For example, one parameter has a fixed set of 9 values. I hard-coded the expression for a text box to:
="Room Size: " &
iif(Parameters!pRoomCap.Count=9,
"Any",
Join(Parameters!pRoomCap.Value, ", "))
How can I do this if the parameter source is a query of unknown size?
Try this out. You need to compare the total number of parameters in the dataset to the count of selected parameters. The following assumes that your multivalue parameter is using a dataset called "dsRoomSizes"
="Room Size: "
& iif(Parameters!pRoomCap.Count = count(Fields!pRoomCap.Value,"dsRoomSizes"),
"Any",
Join(Parameters!pRoomCap.Value, ", "))
This expression will work in the page header/footer.
UPDATE
In the interests of finding a solution to your problem, the following should work for you. It feels hackish and I encourage you to keep research alternative methods but this will work:
Create a second multivalue parameter and name it something like "pRoomCap_hidden".
The source of the parameter is the exact same query
In the parameter properties, setting the default values to the same query
Important: Set the parameter visibility to hidden
This will create a second multivalue parameter in your report that is exactly the same as your initial multivalue parameter only this parameter list will have all values selected by default.
Enter the following expression in a textbox in your header:
=IIF(Parameters!pRoomCap.Count = Parameters!pRoomCap_hidden.Count,"All",Join(Parameters!ReportParameter1.Value,", "))
The above will compare the selected values in each parameter list. If the lists contain the same selected values then that indicates that "All" have been selected in the first list.
Like I said, it is hackish but it definitely works. Until you are upgraded to 2008, this might not be a bad workaround for you.
Can you compare the count of the parameter to the count of the dataset you pull the parameter values from?
I unioned my dataset for the parameters with one which I created manually with a "select" statement - I was then able to force the value to be something like -1 or null.
Then simply check if the parameter contains -1 or null and replace the value in the header with the replacement text.
BTW- I am now using SSRS 2008 R2 and this solution worked for me. My report uses three datasets; but only one in the tabilx that I needed to hide a row in. After long hours of searching and many, many, many unhelpful for wrong answers; the solution of creating a identical parameter only hidden (I marked it as internal) and then comparing to the exposed one is brilliant and easy.
Thank you very much!
