I made a simple query to return 1 field. One of the fields is the user's input.
Item (input)
Description (return value)
I now want to use the returned value in a simple textbox on the report, but it's giving me a scope error. Makes sense, but how do I tell the textbox which dataset to look in (there are multiple datasets)?
If you right mouse click on the text box you can create a placeholder.
You can then specify the value of this placeholder to be the required value from the dataset.

I have an unbound form with some required fields that must be field. I have already executed the vba code to achieve just that. Now my question is how do i specify thefields so that he end user can vividly see those fields. I already have an idea of using red stars but i am open to more suggestions.
You can add (*) symbol in the label that denotes its mandatory to fill.
PICTURE OF QUERY :
I'm plotting graphs for 10 machines (machine 1, machine 2,...) performance -
average vs date graph.
User shall select the machine from a combobox (i made the values obtained from query, or should I make it from the table?) and set it to contain unique values only.
After selecting the machine, user shall click OK button. and a graph of the selected machine should be displayed in a new form.
Problem is, every time I click OK, it prompts me with the ENTER PARAMETER VALUE Forms!ViewReport!Combo9.
After I enter "machine 1" in the ENTER PARAMETER VALUE, it displays the graph correctly. I am expecting the graph to be displayed directly without the error.
The dialog appears because the query has no access to the field Combo9. Probably your form is not open or ViewReport is a subform, in this case, the reference to Combo9 should be different. Check, for instance, this giude for controls references.
But the most reliable method is to create a public function in the standard module, which should return the value from the desired form's field. It can check if the form is open and return the default value if the form is not available or the value is not selected. This function can be used in queries as criteria or in calculated fields.
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.
I've a dijit.form.Combobox field which uses a ItemFileReadStore to pull Its data.
Teh ItemFileReadStore has two attribute per Item value which will be used for form submission , generally Unique Integers and label which is Human Understandable String.
In ComboBox HTML I've done searchAttr="value" labelAttr="label"
When the ComboBox Shows the list it uses teh label Attribute.
But When the User selects one of the Item it shows the value of that Item.
What I want is , The value Attribute will Still be used for Form Submission. But the User will always see the label in the combobox Control.

e.g. I Want to Show The Label for value 3 (Admin) instead of 3
Use FilteringSelect instead of Combobox.
Note: ComboBox only has a single value that matches what is displayed while FilteringSelect incorporates a hidden value that corresponds to the displayed value.
I have tried the following.
var cmbObject = Registry.byId('combo dojo id'); var id =
cmbObject.item.<Code Property>;
You should check if item is null.
