Regarding the content to be inserted in this control, it can be divided into three types: nothing, tables or advanced SQL. Choosing a type, the information in the window changes by questioning different options. Thus, you can link controls to:
None - The control will be empty by default.
Database Table - The control will be linked to a Database Table and the number of records will be the same as the source Database Table. For the data to be displayed, "Refresh Control" Action must be called.
When clicking on the database table option without having entered data in a table, the system immediately alerts you with the following message:
You cannot load the Control with a Database Table because you haven't Added/Created any Table.
SQL Advanced - You can use SQL Advance to fill the combobox.

You can remove or load more options by clicking the buttons on the right in the table.

Tab - Link
Links can be associated with this control. For this, the source must be indicated for them. These can be loaded in two types: database and expression.
Source - Origin of the data to show in the Input Box
Database: Connect the Input Box with a Column of a Database Table.
Expression: Fill the Input Box with the result of an Expression.
- When choosing database the options are:
There are two ways of connecting your Input Box to a Database therefore presenting the value of a specific Column.
1 – You can do it by simply defining the "Table" and "Column" properties and then using the "First Record"/"Last Record"/"Next Record"/"Previous Record" and "Refresh"/"Refresh Plane"/"Refresh Control" Actions.
2 – The other way is to implicitly define a "Select" statement. To do so, you have to define the "Table", "Column", "Where the value of" and "It’s equal to" properties then use the Refresh", "Refresh Plane" or "Refresh Control" Action. This way you are telling Kalipso to perform a "Select" statement like this:
Select <Column> from <Table> where <Where the value of> = <It’s equal to>
- When choosing expression the options are:
A new field is active to be filled in where you are asked to fill in the controlog with the result of ...
Target (store the control's Value in) If this property is set, when Kalipso tries to use the value of this Input Box for executing one of the above Actions, it checks if the value is non empty; if it’s not, Kalipso will produce an automatic error message.
Global Variable – Global Variable where to store the Input Box value;
Local Variable – Local Variable where to store the Input Box value;
Database
Table – Table where to store the Input Box value;
Column – Column where to store the Input Box value;
