Iam using Pentaho report designer and we want to hide a subreport if there is no data .
I have tried to use this formula :
not(isemptydata())
in the visible expression but it does not seem to work .
So how to hide a subreport if no data .
Pentaho Report Designer elements have "attributes" and "style" sections. In style section there is a field "Visible". If you don't want to make the sub-report visible, it must be set to "false".
When want a function to disable it, the expression must return a "FALSE()" value.
You don't specify how the sub-report is generated and where is it placed (Details, Report Footer, etc), but, I'm gonna assume you have defined a function that has the count of rows for a group "TOTAL_ROWS" (and this is gonna be the field you are gonna compare), so, to hide the sub-report when 0 rows are present:
=IF([TOTAL_ROWS] = 0; FALSE(); TRUE())
"if the total number of rows is zero, return false, else return true".

I need a lab report that has several pages. Each test has a unique reference number and I would like it to appear in the header according to what I have on the page. At the moment I only see one reference number and it remains unchanged after switching to another page. See attached image.
If possible, I would like to get rid of the SampleNo column so that its value is only in the header
The easiest way to do this is to reference the the textbox in your tablix that contains the "Sample No.".
Click the textbox that you have highlighted in the tablix, show the properties window (F4 in Visual Studio - can't remember in Report Builder, I think View/Properties).
Find the Name property of the textbox, this is often the name of the field it contains but not always.
In the example below the textbox name is 'oYear`
Next, set the expression in your header to be something like
=FIRST(ReportItems!oYear.Value)
Change oYear to whatever textbox name in your tablix is.
ReportItems refers to the rendered object name so here we just get the first on each page.
Here the first two pages from a small sample of data which groups by year.
I have a simple report with a dataset( Patient id, programid, name, address, phone). In my report footer, I am trying to write a condition where the footer value shouldn't show up for specific program ids. But the report footer doesn't display the dataset fields. How do I write this condition for report footer?
Headers and Footers can't display fields from your datasets because the dataset is out of scope for the header and footer - it wouldn't know which row to display the field for.
However, you can use aggregate functions to specify a scope and the row and field; for example, to show the ProgramId field from the first row of a dataset, you can use the First function, specifying the scope of the dataset:
=First(Fields!ProgramId.Value, "MyDataset")
So you could do something like this for the Visibility-Hidden property of the footer:
=IIF(InStr("10090,116,10094,10083", First(Fields!ProgramId.Value, "MyDataset")) > 0, True, False)
The footer and header sections of an SSRS report cannot have dataset items.
You can use the ReportItems to refer to a text box that is on your page.
Create a text box on your page with the value that you need then refer to that text box with the expression in your footer.
=IIF(ReportItems!TextBox1.Value = 4321, NOTHING, "Your Text Here")
MSDN: Report Items
we can use parameters in footers. you can have a parameter for the specific column and pass the value from code and use the parameter in footer expression like,
=Parameters!Param1.value
Page headers and footers can contain static content, but they are more commonly used to display varying content like page numbers or information about the contents of a page. To display variable data that is different on each page, you must use an expression.
If there is only one dataset defined in the report, you can add simple expressions such as [FieldName] to a page header or footer. Drag the field from the Report Data pane dataset field collection or the Built-in Fields collection to the page header or page footer. A text box with the appropriate expression is automatically added for you.
To calculate sums or other aggregates for values on the page, you can use aggregate expressions that specify ReportItems or the name of a dataset. The ReportItems collection is the collection of text boxes on each page after report rendering occurs. The dataset name must exist in the report definition.
For example, to hide or show a logo based on the value of the Customer Type in the dataset, create a Text Box called CustType in the report body, in that Text Box will be your CustomerType field. Then in the header or footer create another Text Box for your aggregate expression like so:
=ReportItems!CustType.Value = "Direct"
I'm new to SSRS 2012 and have a question about variables. I have a report that retrieves order and order line information from our database (order #, order line #, item, quantity, etc). I need to add a textbox to the footer of the report that can only be displayed for certain items (i.e. if item # equals "123" then show textbox, otherwise hide it.
I added a report variable called 'ItemExists', and unchecked the read-only flag, and set the default value to 0.
I then added an expression to the textbox on the report footer to show it if variable=1, and to hide it if variable=0.
I'm trying to add a textbox with an expression to the body of the report (same group as where the item # is displayed), but I'm unable to get the report variable to update properly. Here's what I tried:
=IIF((Variables!ItemExists.Value = 0) and (Fields!item.Value = "123"), (Variables!ItemExists.SetValue(1)), Nothing)
This works if the value of the item is 123, but if the item is not equal to that value, it still sets the ItemExists variable to 1.
The reason I'm checking to see if the variable is equal to 0 is that there may be multiple lines in the report, and if any one of the items is a match, I want the variable to be set to 1.
I'm not sure if I'm way off track here, but if you could provide any assistance on the best way to achieve this, that would be great.
Thanks in Advance.
My query returns location_cd(string) and item_count(int). I only need certain rows from the result however and I need them to display in specific places in my layout so I don't think the table solution is going to work. Can I determine where I place the value for a particular row of the result set?
I am using a grid to display values for a number of fields. I cannot seem to be able to get the values from the results to show. The grid is bound to the result set. I even tried binding the cells to the result set but that didn't work either.
I checked in the query editor and there is a result set shown in the Preview so I know the query works. The complete and correct result set shows if I put a table on the page.
I tried inserting a Dynamic Text or Data object in a cell and used the expression:
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:""
This returns a blank and does not seem to evaluate. I tested it with :
dataSetRow["location_cd"]=="3SD"?dataSetRow["item_count"]:"BLANK"
and got 'BLANK' to appear in that cell.
dataSetRow["location_cd"] and dataSetRow["item_count"] will display the location_cd and item_count from the first row of the result set. row.outer[] did the same thing. Obviously I am just hacking at this report at this point.
A co-worker suggested that she uses a JAVA if-statement in places like this but I could not get that to work either.
Any ideas or suggestions that will get me on the right road??
Thanks
An elegant option would be to use a HashMap storing the result of the dataset.
Declare a report variable named "values", with a new hashmap as default value (see image below)
Fill values in the onFetch script of the dataset: vars["values"].put(row["location_cd"],row["item_count"]);
Insert new data elements at any place of the report with expressions such: vars["values"].get("myFavoriteLocationCD");
Though it is important to note the dataset should be triggered by the report before these data elements.
The particular row you want to display you specify in a "Text" field inside your grid. Just drag and drop a "Text" field inside your grid. If you bound the fields you want to display to your grid, the "Text" field inside the grid inherits the bindings of its parent (the grid), so you can access the bindings automatically in the "Text" field.
You could try following steps, maybe that works.
Don't use "Dynamic Text" field, instead use a regular "Text" field
Ensure the fields of your query which you use, are bound to the grid (you sayed you already did)
Open the "Text" field
Change preselected pull-down entry "Auto" into "HTML"
Change preselected pull-down entry "Formatting" into "Dynamic Text"
Wrap your code in <value-of format="HTML"> your code goes here... </value-of>
Note: You should check in the "Expression Builder" of your "Text" field if you are able to access the fields you bound to the grid. If they are not available sth. went wrong with your binding. Avoid binding query records to cells this will drive you crazy.
If you want to display a list, ensure you didn't set a constant height in the row of your grid. Set the height to 100% than the row takes its height dynamically.
What about the idea to optimize your query, that only get the results you want are displayed, than you don’t need to filter them with java script? If you don’t need the filtered results in another place this would be the cleaner solution in my opinion.
I'm trying to show / hide fields in a Pentaho report based upon user input.
For example, I would like to offer a checkbox to the user saying "Show Product Count" -- if the box is unchecked, it will not include that column in the report.
Is there a way to do this in Pentaho Report Designer, perhaps using Parameters?
Thanks for the help -Monica
Yes, you have half the answer. Have a Yes/No Parameter "ShowProductCount"
Then on the conditional fields, go to the visible property, click the + formula icon and enter:
=IF([ShowProductCount]="Yes"; TRUE(); FALSE())
Simple! :)
There is more to this that the above answer. For example, if you don't want a field to show on the report, you pass the value mentioned above by Codek but the field will not show but the space for it will. The field has to be in a BAND and the band layout has to be set to ROW. Also, on the field you want to not display or display based on user selection, you have to set that field's style properties under size & position - invisible-consumes-space = false.
