Just wondering if it is possible to do the following on SSRS for a textbox visibility (hide), it seems to return an error for me:
=iif(parameters!category.value = "All",True,False)
I have a long list of category so therefore is impossible to list them all, is it possible to the above? I keep getting an error with the above-outlined syntax
I assume the category parameter is multi-select with available values fed by a SQL query. You can use the Count property on the parameter to get the number of selected items and compare that to the number of items returned by the SQL query using the COUNT() SSRS aggregate function with a scope of the dataset. If the number of selected items matches the number of available values then they must be all selected.
So your code would look like:
=IIF(Parameters!category.Count = COUNT(Fields!CategoryName.Value, "CategoryParameterDataSetName"), True, False)
In this case the dataset that contains all of your available values is named CategoryParameterDataSetName and contains a field named CategoryName. Change these values as appropriate.

I'm using report viewer and trying to create dynamic groupings on my table. Before the report is generated, I have a popup that ask if the report generated should be grouped by category or not.
I have two datasets, one called ReportParameterDTO and the second is called LoanDTO
The tablix is connected to the dataset LoanDTO. I want to create a parent grouping expression for that tablix such that if the first value of ReportParameterDTO.GroupByCategory is true, then it should group, otherwise do nothing.
What I tried
=IIF(First(Fields!GroupByCategory.Value, "ReportParameterDTO") = true, Fields!Category.Value, ""))
It gives me back and error around Fields!GroupByCategory.Value and the error within the error list states that A group expression for tablix includes an aggregate function.
The IIF Expression will compile if I use Field Values from LoanDTO but I don't want to do that.
Add a new parameter.
Set it to Internal.
Set the Available Values to pull from the ReportParameterDTO dataset and the Value field will be GroupByCategory.
Also set the Default Values to pull from the ReportParameterDTO query.
Now you can refer to this internal parameter in your grouping expression like so:
=IIf(Parameters!GroupByCategory.Value = True, Fields!Category.Value, Nothing)
You can create both table and whit your parameter show or hide the table visibility. So like this I think is going to be more easy for you to set up your table and groups.
I thought this would be simple, but i must be missing something
here is my expression
=Sum(ReportItems!ID.Value)/Sum(ReportItems!NumberofUnits.Value)
I get this error.
The Value expression for the textbox 'textbox14' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers.
I really just want to divide those two report item values.
You cannot use an aggregate function (SUM) on a ReportItem. remember that a ReportItem is a textbox or other object inside the report. So either change your expression to:
ReportItems!ID.Value/ReportItems!NumberofUnits.Value
Or in case your ID and NumberofUnits reportitems are inside the context of a dataset (for example, in a tablix), and both of them corresponds to fields in the dataset, do this:
Sum(Fields!ID.Value)/Sum(Fields!NumberofUnits.Value)
You may optionally specify the scope over which the SUM function should work, by adding the name of the scope (for example dataset name, tablix name, group name) as a 2nd argument to the SUM function.
I have a data set that is returning two properties, a name and a total units. I am trying to set an iif expression on a data bar where iif(field!Name.Value = "Name", field!Total.Value, 0)
this is not working I get an error of rsFieldReferanceAmbiguous, the fields refers without specifying a dataset aggregate. And the only option that it gives me as an aggregation is First, but I do not want to get the first name, I want the bar to display the total units base on the name field that is in the iif expression.
rsFieldReferenceAmbiguous refers to trying to match something that is not in local scope. Therefore you have to aggregate it. You are probably wanting something like this:
=Sum(IIF(Fields!Name.Value = "Name", Fields!Total.Value, 0))
The function you are trying to use would be better suited to a calculated field in your dataset. Then you can just refer that that field in your report. This allows you to filter the data line by line instead of by groups.
Right-click on the dataset and go to Dataset Properties.
Go to Fields.
Click Add then Calculated Fields.
Enter the name of the field and then the expression here.
Make sure your tablix has the dataset specified under General -> DataSetName on the properties pane. If you have more than one data set on the report you will need to specify which data set your reffering to like so:
(Fields!Name.Value, "NameDataSet")
If your useing tables you may need to ckeck if you have grouping and if so how your grouping your data.
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.
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)
