I am using Pentaho report designer 5.0 CE.
My report is having two groups, and one group contains row band with elements and values like,
Group1
Group2
Label1 - Value1
Label2 - Value2
Label3 - Value3
...
I need to show a row only if the value is not empty(without leaving blank space).
I set the 'invisible-consumes-space' property to false (band level). The blank space is still there.
how could i hide a label & value (entire row) if the value is empty?
have you tried to put the label element and value element in a band. assumingly value is printed by name field.
this is your band.
-----------------
|label | name |
-----------------
select the band from structure tree and go to style tab->size&position -> visible option.
then open the expression tab and paste
=IF(ISBLANK([Name]);"False"; "True")
OR
=IF(LEN([Name])<=0;"False"; "True")
I use the one below to hide all the group headers & footers when there is no data.
set no data band -> hide-on-canvas option to false. Add a message
field and let's say 'No data available for selected date range'
And set all Report Header & Footer's visible option to:
=IF(ISEMPTYDATA();"False"; "True")
And it works.
Hope helps to you too.
And empty string is not the same as an invisible element. Use the "visible" style instead and add your formula to the band's "visible" style setting to hide the band and all its subbands.

i am using mat-radio-group to bind my data. here data & value are same. which means i have 4 value binded and all 4 value are same. So to differentiate the radio buttons i added index as last value for every radio button.
Now i want to fetch this radio button value into my typescript and also eliminate the lastcharacter(which is index). so i use ngModel & ngModelChange.
I can get the output. but the `mat-radio-button' is not selecting
Here is my code
`
<mat-radio-group class="radioButtonAxis" [(ngModel)]="ngM_Fax" (ngModelChange)="onFaxChange($event)">
<mat-radio-button *ngFor='let data of resultSet;index as i' [value]='data.Fax+i'>{{data.Fax}}</mat-radio-button>
</mat-radio-group>
onFaxChange(value){
this.ngM_Fax = value.substring(0, value.length - 1);
}
`
expecting your help on this.
You are using ngModel wrong. The right value is always in this.ngM_Fax, but it has to match 100% [value]. If you want to use the variable without the index, i would suggest to use an extra variable.
Here is a working StackBlitz.
Trying to show/hide a couple of rectangles in SSRS based on an expression which uses the value of a parameter in the report. See the screenshots for more details. When the '-Cover pages' label is picked I want it to display the rectangle but I consistently get the following errors. It can't seem to convert and read the parameter expression no matter what I do.
The expression I'm trying to use is:
=iif(Parameters!specparam.Value="-Cover Pages",true,false)
It looks like the label of your parameter is what you're looking for based on the image provided and your expression. Try to switch instead to:
=IIF(Parameters!specparam.Label="-Cover Pages",TRUE,FALSE)
(Note: I switched specparam.Value to specparam.Label.
Your comment is very close. Apply this expression to the Hidden property of the rectangle:
=IIF( Parameters!specparam.Label.Equals("-Cover Pages"), FALSE, TRUE )
You'll notice I have switched around the FALSE and TRUE as you don't want the rectangle to hide when the parameter matches.
Edit:
As you're dealing with a multivalue parameter, you can use a combination of Array.IndexOf and Split to check if your value is one of the selected parameters.
Apply this expression to the Hidden property of your rectangle:
=IIF( Array.IndexOf( Split( Parameters!specparam.Value, "," ), "-Cover Pages" ) > -1, FALSE, TRUE )
I have a simple TextBox in my Precision Design related to a Field in Temporary Table.
I need to show this TextBox only If the it value under Temporary Table is pupulated : so if the value field is pupulated (is a string) I show the Text Box , otherwise I don't show the text Box.
I need to set Visibility by Expression :
Which is the best way forward over ?
Thanks!
You can use iif function. Press fx button, here you can writte your code.
iif function evaluate a condition and return 1 of 2 options, for example, in your case you need show one value only if exist.
check this code:
=iif(fields!YourFieldName.value = "", true, false)
if your field is a number
=iif(fields!YourFieldName.value = 0, true, false)
This code evaluate the value of your field and only populate the value if is complete.
I am using an Entry with an EntryCompletion opbject that has a ListStore model.
For each record in the model, there is an image I would like to display in the autocomplete-popup list.
How can this be done?
Is it possible to add a Gtk.CellRendererPixbuf column to the model?
Interesting enough I could not find any examples of this yet it turns out to be possible and not insanely complicated. Lets start with a small image of the goal which uses icons for convinces reasons.
So how do we get there, first we create the ListStore containing a column with strings to match on and a icon-name to convert into a pixbuf (this could also be a pixbuf directly).
# Define the entries for the auto complete
entries = [
('revert', 'document-revert'),
('delete', 'edit-delete'),
('dev help', 'devhelp'),
]
# Setup the list store (Note that the data types should match those of the entries)
list_store = Gtk.ListStore(str, str)
# Fill the list store
for entry_pair in entries:
list_store.append(entry_pair)
Next step is setting up the EntryCompletion and linking it with the Liststore
# Create the Entry Completion and link it to the list store
completion = Gtk.EntryCompletion()
completion.set_model(list_store)
Now the magic, we need to create 2 renderers, one for the text, one for the pixbufs. We then pack these in the completion to add columns to it.
# Create renderer's for the pixbufs and text
image_renderer = Gtk.CellRendererPixbuf.new()
cell_renderer = Gtk.CellRendererText.new()
# Pack the columns in to the completion, in this case first the image then the string
completion.pack_start(image_renderer, True)
completion.pack_start(cell_renderer, True)
In order to make sure the renderers use the the correct column we here specify which column from the ListStore the renderers should read. For the image_renderer we set the icon_name attribute as we give it icon names. If we would feed it Pixbuf's we would need the pixbuf instead.
# Set up the renderer's such that the read the correct column
completion.add_attribute(image_renderer, "icon_name", 1)
completion.add_attribute(cell_renderer, "text", 0)
As there are no multiple column we need to tell the completion which column contains the string. In our case column 0.
# Tell the completion which column contains the strings to base the completion on
completion.props.text_column = 0
# Create the entry and link it to the completion
entry = Gtk.Entry()
entry.set_completion(completion)
And that's it!
I have declared variable in beforeFactory of BIRT Report.
For example:
This variable I am incrementing in table row render like:
Now when all the rows are rendered I want to set above variable to specific cell/ element. I tried
document.getElementName("numberOfMobilityFilesProcessed").text = numberOfMobilityFiles;
AND
reportContext.getDesignHandle().getElementByID
but they are not working out for me.
I had some problems with temporaly local variables used at multiple steps of datasource scripting so I always used global persisting.
After changing your variable you convert it to a String (because only Strings can be persisted) and before editing your variable again, you load the String from persisted context and convert it to the type you want (String to Integer are automatically converted by JavaScripts dynamic typed variables, but don't forget the toString() when you are saving otherwise you will risk an error).
Because you are using reportContext.setPersistentGlobalVariable your variable is accessable in every Element of your Report.
Example:
var rowNum = reportContext.getPersistentGlobalVariable("row_number");
if(rowNum == null){
rowNum = -1;
}
rowNum++;
reportContext.setPersistentGlobalVariable("row_number", rowNum.toString());
Ok, you have a text element displaying a number of row in a table element. The text element appears before the table in the report.
If you are using two separate tasks RunTask and RenderTask:
Add a report variable in your report (see "variable" node on the Data Explorer view). Then you can change the report variable in onCreate() event handler of the table row:
vars["numberOfSomething"] = vars["numberOfSomething"] + 1;
and access its value in an onRender() evenet handler of some text element, for instance DynamicText:
this.text = "Number of something: " + vars["numberOfSomething"];
If you are using RunAndRenderTask, you must look for another approach. In this case an order of onCreate() and onRender() calls is different. You could bind the same DataSet to the text element displaying the counter, as the one bound to the table. Than you can add an aggregation binding to the text element that will count all rows in the dataset.
