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 an SSRS report that has a hidden parameter that is based on a dataset. the parameter is multivalued and is set as the default value as well. If the dataset returns no data is there a way to suppress the message during report preview "The parameter name is missing a value" and continue to load report.
I've not tested this but I would do something like...
Allow null values on the parameter.
Then in your report check the number of selected items in your parameter and set the hidden property of a text box (with your info/warning in) to show the textbox if something nothing is selected. Set the Hidden property to something like
=Parameters!myParameter.Count >0
Alternatively check the first value is not empty with something like
=LEN(Parameters!myParameter.Value(0)) > 0
I have a multi-parameter report in SSRS where I want to display or hide a report depending on the parameter selection. If the user selects only one facility from a multi-value facility parameter then I want a second report to display along with the main report(it would be a separate tab). If multiple facilities are chosen then I only want the main report to display.
I've been playing with the visibility expressions on the second report but I can't seem to get it to work.
I've tried:
=IFF(Parameters!entity.IsMultiValue, "True", "False")
but that returns an error "The hidden expression used in tablix returned a data type that is not valid.
I've also tried:
=IIF(Parameters!entity.Count = 1), "False", "True")
But I get the same error. I'm using SSRS 2016.
False and True are not strings but constants.
Change it to:
=IIF(Parameters!entity.IsMultiValue="Your value", True, False)
And the second one to:
=IIF(Parameters!entity.Count = 1, False, True)
Good luck.
True and False are not strings, they are booleans. The Visibility property looks for a boolean, but in the expressions you gave (assuming your syntax was correct when testing it), you are passing strings since you have them enclosed in double quotes. Remove the double quotes and that will clear that error.
You also don't need to use IIf here -- you can simply use the first argument of the IIf, since that by itself will evaluate to True or False. I doubt there is any appreciable performance difference, but just a small thing to note.
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'm using Microsoft Visual Studio and I'm trying to stop duplicate rows. The row in question is grouped. Under field properties there is an area called Visibility. For the Hidden value I am entering
Fields!fp_id = Previous(Fields!fp_id, True, False)
I get the message that it is not a valid Boolean value.
The previous Function has this signature:
Previous(expression, scope)
Also, you're calling the field itself instead of its .Value.
Finally, SSRS usually doesn't like comparison statements in places where it wants a single final value.
Try this:
=Iif(Fields!fp_id.Value = Previous(Fields!fp_id.Value), True, False)
The Iif function has this signature:
Iif(TestExpression, TrueValue, FalseValue)
I am working on a SSRS Report.
In the report , i need do display a field of type: boolean that is either true or false.
When I try to display it on the report , it's showing as true/false.
But, I would like to represent it as yes if value is true and no if false.
I think one way of doing is by changing the query that gets data to report.
But I would like to know, is there any way we can write that condition in the report itself
to change representation.
You can use an expression field, add a textbox, right click => expression and use something like this: =IIF(Fields!LineTotal.Value = True, "This is true", "This is False")
