I've been reading Telerik's documentation and I'm not sure if this is possible: I'm being asked to add tables to a report at run time, without doing so programmatically. A query is run that fetches hierarchical data, and the report owner would like to add a new table to the report for each member of the topmost parent, so that each topmost parent has their own table, with a text box title on top of the table containing the parent's name, in the following pattern:
TopParent1
[Parent1's table]
TopParent2
[Parent2's table]
...
Does anyone know how I could go about doing that without doing so programmatically? Every example and/or bit of documentation I've seen pertains to programmatically adding tables.
It is possible to add tables to a report at run time, without doing
so programmatically?
R: It's not possible to add table with out saying programmatically : the size of each element , the exact position , etc .. .. ..
HowTo create a 'hierachical' report with conditional display ?
1/. Hierachical Report.
Read the telerik official tutorial on How to: Create a Master-Detail Report Using a SubReport Item
Using the SubReport report item you can display one report within another report. The data for each SubReport can be completely different.
But You can achiev Parent/chield relation by Passing Parameters to a SubReport.
/!\ Caution /!\
Page sections are not related to the report itself, but are relative to the paper or screen. Thus page sections of nested/detail reports are ignored and only the page sections of the main report are visible.
In order to have sections that repeat on every page similar to page sections, consider using an unbound group (no grouping criteria specified) and set the PrintOnEveryPage property of its sections to True. Be aware that you cannot use PageCount and PageNumber global objects in group sections.
2/. Conditional Display
You will need to hide Report if subreport have no result.
If you want the user to choose if he want some sub report.
You can do it by passing parameter from your calling application to your report constructor.
And use Something like a Bitfield or an enum to choose what to display.
And What about a C# controler in the master report code behind ?
public myReportConstructor(int SubreportToDisplay)
{
InitializeComponent();
Hiden_Display(SubreportToDisplay);
}
private void Hiden_Display(int _code)
{
if ((_code & (int)myEnum.InfoClient) != (int)myEnum.InfoClient)
HideNShrink(SUBREPORT_CLIENT);
if ((_code & (int)myEnum.Item) != (int)myEnum.Item)
{
HideNShrink(SUBREPORT_Product.Item1);
HideNShrink(SUBREPORT_Product.ItemTWO);
}
}
private void HideNShrink(ReportItem target)
{// http://www.telerik.com/support/kb/reporting/details/collapse-the-container-when-hiding-child-report-items-
target.Visible = false;
target.Height = Telerik.Reporting.Drawing.Unit.Pixel(1);
}
I use a little trick here in my designer every subreport item is set to public:
private Telerik.Reporting.TextBox textBox17;
public Telerik.Reporting.SubReport SubReport_Client;
public Sub_Client sub_CLI1;
When hidding Client I will use the SubReport_Client.
That is the SubReport item, the container of my SubReport Sub_Client ;
(Yes they name the container and the containt are the same name, thats confusing at First, but it's Vs/Telerik choice)
When hidding a Sub Report That is in an other Sub Report.
I use the ContaintSubReport, Container of the nested-nested SubReport.
like: sub_CLI1.nested-nested_SubReport
I was able to answer my own question as follows:
Create two blank reports.
On the report chosen to use for the detail report, remove the report header and footer.
Add data source and parameter/s to the detail report (in my case, an SQL data source) and set report data source to the data source created here.
Add group to report with the value of groupings set to the top-most result in query bound to report. (Groupings = Fields.Parent)
Create text box with the value set to the field for the top result (textbox1.Value = Fields.Parent) or use data explorer to drag and drop Fields.Parent into the group header.
Create text boxes to mimic table column heads (one text box for each title of the columns) and place them into the group header with the text box containing the topmost result (or Fields.Parent).
Drag or create text fields for the rest of the fields in the query (Fields.Child1, Fields.Child2, Fields.Child3, etc) in the detail section of the report, aligned vertically with their column header. Preview the report--it should contain a table-like structure that repeats on each top result.
Switch to other report.
Add same parameter/s to that report.
Add subreport item to the detail section of that report.
Set subreport report source to Type and report document, then select the name of the detail report (the first one created here).
Set parameter/s for subreport to the same parameter/s used in the subreport.
Using that, I was able to essentially add a table per item in the first column of the query. The report created first serves as a wrapper for the query, and because it's being placed in the other report as a subreport item with the grouping I created, it is allowed to repeat as much as it needs to in order to display all the rows in the query.
I used the Telerik documentation for master-detail reports and report structures for this.

Can dynamic text be entered into a header or footer of a master page?
I have placed dynamic text into a grid which then sits in the master page footer, this doesn't work and gives error:
ReportDesign (id = 1):
+ Invalid javascript expression: ReferenceError: "row" is not defined. (<inline>#1)
When I test the expression in the footer of the report layout itself this works.
Please see the expression below:
if( BirtComp.lessOrEqual( row["Aggregation"], "1,500.00" )){"user1.jpg"}
else if (BirtComp.greaterThan(row["Aggregation"], "1,500.00")){ "user2.jpg"}
The easiest way to use dynamic text in the master page is as follows:
Optional, but recommended: Create a dataset "MasterPage" which selects the dynamic data that you need.
Create a grid in the page footer (and/or header) of the master page.
Bind the grid to the dataset "MasterPage".
Use dynamic text items and data items inside the grid as you like.
Important:
The grid uses only the first row returned by your dataset.
Thus, it is best practice to create the dataset in such a way that it will return exactly one row.
This means that BIRT aggregation functions won't work here.
If your "MasterPage" dataset is JDBC based, you can of course use SQL aggregation functions like SUM, COUNT etc.
It is not possible to access "the current first record for the current page" this way: The "MasterPage" dataset returns one record for the whole report.
I have a report where I need to add a note/number where a record has data in a particular column. I then need to add a reference to that to the bottom of the table, much like a footnotes section you would see in a book.
I've tried adding the rownumber but it pulls in the actual rownumber and not the record count. I'm using oracle for my db.
In my report, if the record has a value for the column RETURN_NOTE (not shown), then concatenate an int tot he end of the TASK_NAME column. Then underneath the table, add the int from above with the RETURN_NOTE value.
You can see the red numbers and their description in the image below.
Thanks
The best way to go here is when you add a calculated field to your dataset where you put your footnotes into the expression. Lets assume your footnotes depend on the Fields!Task.Value and lets call this calculated field Footnotes:
'Name: Footnotes
=Switch(Fields!Task.Value = "Prepare for Coordinator", 1, Fields!Task.Value = "Ready for Closeout", 2)
Now add another column to your tablix and put the field Fields!Footnotes.Value in this column.
Then add a rectangle or another tablix somewhere in your report (put in the values which explains the footnotes). Then go to the properties of this tablix/rectangle (pane on the right) and under Other > Bookmark write in a bookmark code (for example: FootnotesExplained).
Go back to your textbox with the Fields!Footnotes.Value in it and right click on this textbox and go to Text Box Properties > Action and check the Go to bookmark option and write below your bookmark code from before FootnotesExplained.
When you click now on one of the value in the column where the footnotes are the report will jump to the tablix/rectangle where your footnotes descriptions are.
I'm trying to create a report with some controls "anchored" to the very end. The difficulty is that I can't add this to the page footer because the report could span multiple pages leaving a giant white space at the end of each report if I decide to toggle visibility. The items I have should only appear on the very last page and be positioned just above the footer.
For example, in this scenario, I need the letter's closing signature, titles, etc. positioned at the very end of the last page the report spans.
As an alternative to adding a sub report you could try the suggestion below.
It all depends on how you data is laid out in your report whether it could work for you.
If all the data required to populate the controls exists in the report dataset why not add an outer lever of grouping that encompasses the entire dataset. You could do this using a dummy column containing 1 for example.
Just add a footer to this group and put your data in the group footer.
You can additional rows as necessary to the group footer.
This footer will always appear as the last row(s) in the tablix
I am fairly new to BIRT reports.
In the BIRT reports designer I have added a 2nd row to my table which is binded to a data set. In this 2nd row I want 1 column from my data set to take up the whole row.
So what I did was to add the second row and merge all the columns in that row to form one column. I then added a text field with Dynamic HTML Text.
<VALUE-OF>row["ITEMDESCRIPTION"]</VALUE-OF>
The problem I have is that the data is not taking the whole row. It is being wrapped into only a small section of the row. I must be missing something. Can someone help me with this pls.
I'm attaching both the way the end report looks like and also the screenshot of the set up in the designer.
End Result
Designer (you can see all the rows merged in the second row of the table and in the properties i can see a colspan of 10 for that single column)
thanks
I've found out that the asnwer to this question is to make the field element inline style rather than block and also to check the No Wrapping check box for this field int he designer.
I am a relative APEX noob.
I'm running APEX 4.0 against a 10gR2 database.
I've written a query that takes a few inputs (two date fields, for start and end, and a text field for further filtering) and created a dynamic report out of it that works when I pull the input variables (:START_DATE, :END_DATE, :OFFICE) out of it or replace them with static values.
I want to create a form on a page that submits those values to the dynamic report page for use in the query to filter the results the user sees when he or she hits the report.
I'm not having much luck finding a good step-by-step example of this. I created a blank page with two Date Pickers and a LOV select dropdown, but am unsure how to best translate those values into the dynamic report.
Can somebody point me at the right documentation for this?
The following was developed using Apex 4.1 but apart from some cosmetic changes the principles should be the same.
The data comes from the standard scott.emp schema.
Overview
This is page 1, the user can enter an empno and\or a hiredate.
When submit is pressed the following report on a different page is displayed:
How it works
On page 1 I have created the three items shown. The text items are called them P1_EMPNO, and P1_HIREDATE. The action for the button is "Submit Page"
Still on page 1, create a branch with the following values:
This branch navigates to page 2 (which is yet to be developed) and sets the values of items on page 2 with the values from page 1.
Create a new page, in this example this will be referred to page 2.
On page 2 create a new interactive report using the following query:
select e.*
from emp e
Next create two text items in the same region as the report and call these :P2_EMPNO and :P2_HIREDATE. I have found it useful to show these items during development so you can see that the correct values are being passed through to the page. You can always set them as hidden once you happy with the report.
Finally amend the query used by the interactive report to use the values supplied by page 1
Run the application.
You want to reference your page items in your query, which means you'll have to submit your page before your query will pick up the session state of them. What I do when I provide a small parameter form, is to put a button up there as well (i.e. labeled 'Query'), which does a submit.
In your report you can then reference your items. If for example you have 2 items P1_DATE_START and P1_DATE_END, your query could look like:
SELECT firstname, lastname, job
FROM employees
WHERE employment_start BETWEEN to_date(:P1_DATE_START) AND to_date(:P1_DATE_END);
