I am using a parameter to change the background color of my field when the field string contains the parameter string .
I have used IndexOf, Contains, and instr. All three work, however they are all case sensitive. (i.e. when I search 'Dol' Dollar Tree and Doldrum are highlighted but not Sandolski etc.)
It is not the stored procedure, the correct records display, however the SSRS functions are what is my challenge.
I have tried toLowerInvariant but was receiving an error Help please.
As I was writing this I checked my error and learned the issue..
I assumed the syntax was to pass my string as a parameter:
toLowerInvariant(Parameters!Param1.Value)
However the correct toLowerInvariant syntax is (in ssrs):
Parameters!Param1.Value.toLowerInvariant()
An explaination on toLowerInvariant can be found here: string.ToLower() and string.ToLowerInvariant()
And also I have found that this comparison is best done with a Switch (if you are comparing multiple parameters to the field).
I have not noticed a performance impact between Field.IndexOf(#Param), Field.Contains(#Param), or Field.Instr(#Param)
My final code:
=switch(
instr(Fields!Client.Value.toLowerInvariant(),Parameters!Client_Firm.Value.toLowerInvariant()) >= 1, "Cornsilk",
instr(Fields!Client.Value.toLowerInvariant(),Parameters!KeyWord.Value.toLowerInvariant()) >= 1, "Cornsilk"
)

I cannot work out why these Total expressions don't work...
I am trying to add any cells that have a date later than today, with any cells that have "Not Reqd", and then divide that by the number of rows, to get a percentage.
All I'm getting is #Error.
These are the expressions I've tried:
=SUM(IIf(Fields!Jetter_Trng.Value >Today OR
Fields!Jetter_Trng.Value = "Not Reqd",1,0)))/(Count(Fields!Jetter_Trng.Value)
and
=Count(IIf(Fields!Jetter_Trng.Value >Today OR
Fields!Jetter_Trng.Value = "Not Reqd",1,Nothing)))/(Count(Fields!Jetter_Trng.Value)
The "Not Reqd" string has come from an expression that changes a date (01/01/1950) to "Not Reqd". Maybe this is messing things up:
=iif(Fields!Jetter_Trng.Value = "01/01/1950", "Not Reqd", Fields!Jetter_Trng.Value)
The current working expression (not looking for "Not Reqd") is:
=COUNT(IIF(Fields!Jetter_Trng.Value>Today,1,Nothing)))/(Count(Fields!Name.Value))
I'm a bit lost...
A couple of notes on your expression as it stands at present
Jetter_Trng appears to be a string representing either a date or “Not Reqd”. You can’t compare strings to dates without casting them to a date type first using CDATE()
The number of braces (( and )) do not match
The root of your problem though is that you are using Jetter_Trng to return either a Date, or the value “Not Reqd”.
When SSRS attempts to evaluate an expression it does it all at the same time. It doesn’t follow a path to find the answer, and ignore other paths. Therefore, when you are attempting to compare
Fields!Jetter_Trng.Value >Today
This is comparing a string to a date, and throwing the error, as this mean nothing
"Not Reqd" > Today
You won’t be able to do all that you want to using only one Field of type string.
Your options are to
Use two fields – the date and a flag indicating not required, or
Use one field – but have an “invalid date” (01/01/2100 perhaps) that you could then treat as the “Not Reqd” value, and check if the current date is less than that (which it always will be)
Using the second option here you could then use the following expression to create the desired calculation
=sum(iif(CDate(Fields!Jetter_Trng.Value) > Today, 1, 0)) /
Count(Fields!Jetter_Trng.Value)
Which would evaluate this dataset as follows
So i'm testing sample code and I pasted some online text into a field and i'm getting an error and I have no clue why. Here is the entire method which is throwing the error:
EDIT the error is coming from the assignment. However, there is no
error thrown on any number of other input strings.
CurNodeName = RTrim(CurNodeName)
ADORecordset.Fields.Append CurNodeName, adVarChar, 500, adFldMayBeNull
tempString = XMLValueDecode(CurNodeValue)
ADORecordset.Fields(CurNodeName).Value = tempString
...
Here is the string which is being passed into the method:
Most of the methods of the DoCmd object have arguments ? some are
required, while others are optional. If you omit optional arguments,
the arguments assume the default values for the particular method. For
example, the OpenForm method uses seven arguments, but only the first
argument, FormName, is required. The following example shows how you
can open the Employees form in the current database. Only employees
with the title Sales Representative are included.
Here is the exact error description:
Multiple-step operation generated errors. Check each status value.
That is the whole story, and i just don't understand it. Can you tell me why this error is happening?
(From a comment to another answer:)
There must be some critical difference between adVarChar type and adVarWChar that the text being set responded differently to.
It was many versions ago (Access 2000, and the release of Jet 4.0) that Text and Memo fields in Access were upgraded to handle Unicode. From that point forward, Text fields and parameters needed to be referenced as adVarWChar (with a maximum length of 255), while Memo fields and parameters needed to be referenced as adVarWChar or adLongVarWChar (with a theoretical size limit of approximately 1 billion characters).
It is unclear why the code in the question would work for some strings and not others, but certainly using the correct ("W") data type would be a prerequisite.
Have you checked curNodeName for type? If you've passed a numerical type to append, it might be converting it to string implicitly when naming the field to avoid indexing errors, if that's the case, (and you are inadvertently trying to assign that string to the value of a field with an index that is not currently in the collection,) you might be throwing that multi error because you'd be trying to assign a string of a length longer than the default length to a field with an index way outside the current collection (either of which error alone might throw a specific exception, but depending on the way the parser is handling those terms, it might evaluate each side of the assignment for validity before trying to assign an error code.)
What I'm wondering is if you've debug.printed (or just counted, depending on collection size) the field names and indices as matched pairs and tried assigning the string to your field by index instead of name?
I am getting this error every time this report is rendered. I looked at the group expression for this group and it looks like this:
=Trim(Left(Fields!ILS_LS_USER_10.Value,InStr(Fields!ILS_LS_USER_10.Value,"->")-2))
The field ILS_LS_USER_10.Value is: BNST -> USWEOLN
I can't see the error. Can anyone help me diagnose this error, please?
It works if you put the string literal in place of Fields!ILS_LS_USER_10.Value.
The issue is that it isn't getting the value of the field as a string by default. Use the ToString() method after .Value and it should work, or at least it did on my machine.
=Trim(Left(Fields!ILS_LS_USER_10.Value.ToString(),InStr(Fields!ILS_LS_USER_10.Value.ToString(),"->")-2))
I found that the Group expressions, for some reason, do not seem to like the subtraction in the InStr. Leave out the subtraction and it works.
In fact, take the same formula, and place it into a placeholder in the Group and it seems to work just fine. Replaced with Split in the Group expression and it works.

I'm having an issue and everything i've tried doesn't work. I have a phone number datafield that returns numbers with no formatting '3055558798' but i want it to look like this '(305)555-8798'. I can get that done with this expression:
= Format(Convert.ToDouble(Fields!MyFieldName.Value), "(###)###-####")
The only issue is that when the return is null i get #ERROR in the space. I found an expression that got rid of the #ERROR but still no luck putting them both together. I would have to dig through my reports to find the expression but hopefully someone can help me. I've been doing reports for a couple of months but i'm still not very good with all the expressions that there are. I just need to format the phone number and if the return is null then not show anything. There's also this on the same site that i found the expression but it doesn't work so i dont know why the guy said it worked for him.
=Iif (Fields!MyFieldName.Value Is Nothing, Nothing,
Format(Convert.ToDouble(Fields!MyFieldName.Value), "(###)###-####"))
That just doesn't work for me, I believe the syntax is wrong but i don't know what to change to fix it. Thanks.
The error you have got is nothing to do with formatting, it is the conversion to Double that is failing. So your expression works perfectly as long as your field consists entirely of numeric characters. However, you have some data with non-numeric characters in it, causing the Convert.ToDouble() function to throw an error.
Unfortunately this can not be solved with an IIF expression because IIF is a function, not a language construct so both the true and false parameters get evaluated before being passed to the function regardless of the value of the boolean condition parameter. This means that:
=IIF(IsNumeric(Fields!Phone.Value), Format(Convert.ToDouble(Fields!Phone.Value), "(###)###-####"), Fields!Phone.Value)
will always attempt the conversion to double regardless of the result of the IsNumeric function. There are two ways to solve this:
Use Val instead of ToDouble
The problem with ToDouble is it errors when the string to be converted is an inappropriate form; Val doesn't have that problem - it simply grabs whatever numbers it can. So now we can use the expression:
=IIF(Fields!Phone.Value Is Nothing,
Nothing,
IIF(IsNumeric(Fields!Phone.Value),
Format(Val(Fields!Phone.Value), "(000)000-0000"),
Fields!Phone.Value)
)
(Use 0 rather than # so that leading zeroes aren't suppressed)
This expression returns Nothing if the field is Null, checks to see if it is numeric and if so converts it to a number and formats it, otherwise it just returns whatever is in the field.
Note that the Val function is still being run even when the field is not numeric but this expression succeeds because the Val function doesn't raise errors like ToDouble. We simply make the calculation and discard the result.
Custom code
On the Report menu, click Report Properties... and go to the Code tab. Insert the following code:
Function FormatPhone(Phone AS String) AS String
IF (Phone Is Nothing) Then
Return Nothing
Else If (IsNumeric(Phone)) Then
Return Format(Convert.ToDouble(Phone), "(000)000-0000")
Else
Return Phone
End If
End Function
Use the following expression in your phone number cell:
=Code.FormatPhone(Fields!Phone.Value)
SQL Server 2008 R2, using BIDS to design the report.
I have a table and I am trying to only show a certain row. Maybe there are better ways to do this, but I am coming across an error with the filter expression and regardless of how I achieve my initial task, I'd like to understand the filtering.
I started with the filter expression (set to type "Integer"):
RowNumber(Nothing) = 1
This gave the error:
Cannot compare data of types System.String and System.Int32.
I found the solution to this is to change the 1 to "=1" as 1 is evaluated as a string.
So I then had:
RowNumber(Nothing) = =1
That changed nothing, I got the same error.
Then I tried to do that to the first part of the expression:
=RowNumber(Nothing) = =1
This changed the error to a deployment problem (still builds, which is frustrating):
Error pvInvalidDefinition : The definition of the report '/ReportName' is invalid.
I then tried using CInt on RowNumber:
CInt(RowNumber(Nothing) = =1
Then I can deploy it, but the error just changes back to the first one:
Cannot compare data of types System.String and System.Int32.
It seems no matter what I try here I either can't deploy the report or I get an error that I'm comparing a string to an int.
RowNumber returns an integer, so it seems like this should work. I've tried using the name of the dataset in place of "Nothing" but that doesn't change what I'm seeing.
I realize there are many ways to solve my initial problem, but I am curious as to why the filter expression is invalid.
Its better to hide a row with visibilty property. Just click on any text box and go to visibily tab . You can now click on show or hode and go to expression.
That default to Hide . So write an expression there to hide the row.
=IIf(NOT(RowNumber = 1),TRUE,FALSE)
Let me know if you get any error
RowNumber is not available to use in a Tablix Filter.
Using RowNumber(Nothing) <> 1 as a Row visibility property fixed the issue.
Using BIDS you are not given any error that indicates what the problem is, but importing the report to Report Builder and deploying it from there will give a more descriptive error that, in the end, helped me to solve my problem.
