Eclipse RCP 4 - binding column in table and iobservable value - eclipse-rcp

I have the following issue - I have an IObservableValue, which is changing, and should be displayed in the first column of a table. The values in the other columns are based on this value (in each other column the value is calculated and the value is dependent on the value in the first column). How can this be done?

Perhaps you can try binding to a jface viewer. The tutorial here uses jface tree but it should work similarly with tables.

Combo Box Dropdown List from Table

First time creating forms to insert into a database.
I'm trying to create a drop down combo box that lists the entries in the second column...
This is in a seperate table. The issue I'm running into is how do I show what's in the Description column, but when I insert into the form, it's corresponding PMRT_Need value is put in the table.
The database is as such that it HAS to be the PMRT_NEED value unfortunately.
Thanks for your time!
After setting the Row Source to your appropriate table/query:
Set the Bound Column to column 1 (i.e. the PMRT_NEED field)
Set the Column Count to 2
Set the Column Widths to something like 0cm;5cm (adjusting the second width to suit your data) such that the first column isn't displayed to the user.
This ensures that your combo box returns the value of the PMRT_NEED field for the selected item, but only the Description is displayed to the user.

In Tableau, Is it possible to give Column number in Column Shelf

I'm using Tableau. So, instead of giving the [Column_name], Is it possible to give [Column_number] in column shelf?
- Hariharasudhan. R.
No -- for good reason.
Think of the data source as a template for a potential SQL (or MDX or TQL) query; specifying tables, joins, unions and possibly some where/having clauses for data source filters.
The actual SQL generated for any particular view will be an (optimized) query that only selects columns that are actually needed for that particular view, adds where/having clauses based on the filters being used etc.
So a column doesn't have a fixed number. The same column may be the first field selected in one situation, the last field in another situation, and left off completely in another.
If you want to change the name of column shelf:
Create a duplicate of variable and change original with duplicates and assign name as your wish by right-click on Edit Aliases and change as per your requirement.
Go to Data Source
On the middle right corner check on Show aliases
Go to column and right click on it. Go to Rename

Hide duplicate row SSRS 2008 R2

Duplicated data is coming in my report because source table has duplicate data. Without creating group, I want to hide duplicate data writing expression. So what I did: I select table row and put a expression for hidden property of table row.
The expression was like =(Previous(Fields!ID.Value) = Fields!ID.Value)
but it did not work ... Still duplicate data is showing. So tell me how to suppress duplicate rows in ssrs writing expression not by grouping.
You probably should try these options first:
Try to clean the duplicate data at the source.
Change your source query so the duplicates don't appear in the dataset. (e.g. SELECT DISTINCT)
If not, on the row's Visibility Hidden property you can use the Previous function:
=iif(Fields!YourField.Value = Previous(Fields!YourField.Value), True, False)
You would have to sort on the YourField column for it to work.
I was putting the expression above also until I started using the "Hide Duplicates" line in the properties pane. You basically just select the row, in the dropdown choose your Dataset and that's it. any duplicates will be hidden. Also if you just want to hide certain textboxes duplicates you can do the same as i stated earlier except click on the textbox and not the row. Just another alternative, i'm aware you said using an expression.
You can do it using expression or "Hide Duplicates" options from cell or row properties.
Expressions :
=IIF(Fields!YourField.Value = Previous(Fields!YourField.Value), True, False)
Hide Duplicates Steps:
Select row or cell
Click on F4 key on your Keyboard
Look for "Hide Duplicates"
Choose your DataSet from the dropdownlist
Done, I hope that helps
As an alternative option, you can do it by setting row groups. In a report I was trying to create, the Hide Duplicates property wouldn't behave correctly because of using the same dataset multiple times in a list container.
All you need to do is set the row group properties for the default row group (rightclick the grey row header, and go to Row Group then Group Properties), and add Group expressions on the General tab. Add as many as you need for each field. It's like the Remove Duplicates tool in Microsoft Excel
Sometimes the Hide Duplicates option does apply to the report content. If you add a =Sum(Field!Field_Name.Value) sum around field in the cell, it suppresses the copy from previous record. Of course, strictly speaking this is a solution where the incoming data set has NULL rows for the cells with the issue.
Since the using of Previous function in SSRS compare to the only record previous to it, thus it might cause the duplicate of records still shown if the repeated records not next to each other.
Use the sorting on each table you apply the Previous function, it should resolve the "non next to each other" duplicate records as well.

Displaying tables below each other in JasperReports

I have to create a report where several tables are diplayed below each other. Each table gets its data from a SubDataset and contains none, one or more rows.
For the first version of the report, I've simply ignored the possibility of a table having no rows and put all tables below each other, each with the height of 1 row. The idea was, that if there is more than one row, the table will grow in height, which seems to work fine. I've given the first table a fixed position and set all subsequent ones to float. In iReport it looks like this:
But when I create a report, only the first table is at the expected position. The rest is displayed too low and overlaps:
Any idea how to fix this? I can't use subreports, because the report is stored in a database so I can't reference other reports. Is there maybe another alternative to subreports or tables?
You have the "Position Type" property set to "Fix Relative to Top". Change it to "Float".
Try looking into using subreports. I do create table followed by another (datasource is XML).
create subreport using xPath
Use Data Source Expression property of the subreport to set the datasource for subreport
((net.sf.jasperreports.engine.data.JRXmlDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("/FUND_STATEMENT/FUNDS/FUND")

How do I hide the left-most column in an SSRS 2008 matrix?

I have a matrix in an SSRS 2008 report. The rows are grouped on the Time field, and the columns are grouped on the FieldName field. Pretty standard stuff, you can see the designer view of it below.
This works pretty well, except that in some instances I need to hide the "time" column (highlighted in the image).
I've tried setting the Hidden property, both on the column itself and the individual fields. This leaves a large empty area where the column would normally display. I've tried setting the hidden value for the time row group, but that hides the entire row of data.
Is there any way to hide this information with SSRS 2008?
I was able to find a work-around with a little experimentation. Here's what I did:
Added an adjacent column group to the FieldName column. This column was grouped on Time (the same as the row group).
Set the header of the new column group to always display the text "Time."
Right-clicked on the selection button for this new column and selected "Column Visibility..." from the list. Entered the hidden expression I wanted.
Deleted the original Time column, choosing to retain the associated group.
