I have 18 Boolean parameters in my report. I want to make their default value to false through expression when ever user runs the report.
I am trying this but its not working
=SIDIdNum.Value = "false"
Getting Error: parameter SIDIdNum caontain an error [BC30451]
Have you tried just...
false
I'm also not sure where you're trying to set this value? If you are accessing the parameter from somewhere other than parameter properties dialog, you'll need to use
Parameters!SIDIdNum.Value="false"
I had to tweak the prior answer in SSRS 2012.
I needed to make the value: =false

I am using visual studio 2008 to write a reporting services report.
I am trying to conditionally hide a textbox/label on my rss report. I have an integer input parameter the user in the form marks yes or no, but the parameter is assigned either a 0 or a 1 depending on the answer.
My current expression is:
=iif(Parameters!#onetime.value = 0, True, False)
I get error bc30455, argument not specified for parameter 'TruePart'... blah blah
It looks like you may be declaring the parameter incorrectly.
Your parameter should look like Parameters!onetime.Value without the # sign.
Additionally, for the full statement, I'm assuming this is being used in the visibility settings. For that property, False means the textbox will be visible and True will hide the textbox. The expression you'll need should look like this:
=IIF(Parameters!onetime.Value = 0, True, False)
This expression will hide the textbox if the onetime parameter is set to 0.
You seem to be using the parameter incorrectly.
If your parameter is named onetime, the expression should be
=IIf(Parameters!onetime.Value = 0, True, False)
When using the expression editor, you can insert the correct syntax by selecting your parameter from the list of parameters.
Using this expression in the Visible property, the textbox will be visible if and only if the onetime parameter is set 0.
I have a rectangle.
I want to hide it if a field (X) is NOT NULL.
I tried this but it is not working:
=IIF(NOT IsNothing(Fields!filepath.Value), 1, 0)
I get the error:
An error occurred during local report processing.
The Hidden expression used in rectangle 'ID2398' returned a data type that is not valid.
Anyone know why I'm having this issue?
Do I need to place the actual field onto the report? I tried it but I keep getting the same error.
If you're using that for the Visibility expression, I believe you need to explicitly use True/False rather than 1 or 0. So try:
=IIF(NOT IsNothing(Fields!filepath.Value), True, False)
I do prefer to use =iff(Fields!filepath.Value IsNot Nothing, Fields!filepath.Value, ) in Textbox/Properties/Visibility/Hide as it is more intuitive for me.
In my report, I have an expression which is used to pass a parameter to a child report parameter which is set to allow null values. The expression is :
=IIf(Parameters!Lead.Value = "False",Nothing,Fields!Paid.Value)
The above expression returns values only when Fields!Paid.Value is not blank. Therefore when Fields!Paid.Value is blank I get an error
"the value provided for the report parameter is not valid"
How do I modify my expression to parse these two conflicting issues?
What I want is to be able to return values when the Fields!Paid.Value is blank or when it is not. So at all time when the expression runs corresponding values are returned without the error stated above.
Thanks for helping out.
The first thing you do, wherever you have used the "Paid" parameter, set it to allow null value. Allow null only not blank.
The second thing about the expression, use something like this,
=IIF(Parameters!Lead.Value "FALSE", Nothing, IIF(IsNothing(Fields!Paid.Value),0,Fields!Paid.Value)
I have a drilldown report whose parameters are: parent report - #valid Nvarchar(20) = '' and in child report - #valid Nvarchar(20) = Null.
Both reports run very well but I have an issue after mapping up this parameters in the Text Box Properties > Action > Go to Report. When the report is run I get the error,
"the value provided for the report parameter is not valid"
The query for this report is from a stored Procedure. In the child report, Parameter Properties, I have ticked the "allow Null values" text box, Set available parameter to come from a query and specify a default value to come from a query. What have I done wrong to allow for the error returned? Your help is appreciated.
Thank you.
If you're second report is expecting a NULL values, (i.e. Nothing in SSRS), you can pass an expression-based parameter to the child report based on the parent parameter, making sure that if it's an empty string at the parent level, you can explicitly set this to Nothing:
=IIf(Parameters!valid.Value = "", Nothing, Parameters!valid.Value)
This way the empty string will never get passed and your child report; only the NULL value it expects.
if you're considering passing a null parameter from URL, let's say some sort of CLI, you must include a parameter:isNull=True in the parameter section of the URL. and allways remenber to check the "allow null value" in report editor, parameter properties.
let's say we have a report, of sports and stadiums, and we have a null sport... it would be something like this>
http://<server/report>&rs:Command=Render&rc:Parameters=false&rc:toolbar=false&sport:isNull=True&stadium=CampNou
Set the Parameter to Allow Blank = Yes and the Default Value = "". In the code make allowances for the blank parameter.
I created a new report for an overview of a company. I added a report parameter, which default value is determined by query. But if I run the report and this query returns no results, I get the error "Parameter x is missing a value."
I found this post Parameter is missing a value ssrs 2008. But setting the available values to none didn't solved my problem. I allowed empty and null values too.
If I make the parameter visible everything is okay, I can choose a value or not and it works.
My parameter has following settings:
Type: text
Allow empty values: true
Allow null values: true
Allow multiple values: false
Parameter visibility: Hidden
Available values: none
Default values: Get values from a query (this query sometimes has no results)
This appears to be a glitch with SSRS.
From this MSDN blog post:
Force the update of the properties by renaming the parameter
Open the report for editing in Visual Studio.
Expand the Parameters node and rename the affected parameter to ParameterName1.
Set Allow Blank and Nullable to True if not already set.
Deploy the report.
Rename the parameter back to ParameterName.
Deploy the report.
