General
Condition elements can be used to exclude certain parts of a Template based on a condition.
Properties
This type of report element has the following properties:
Name | Description |
|---|---|
| Name | The name of the condition element. This name will be displayed in the tree hierarchy of the content explorer of the Report Designer. |
| Code | The code of the condition element. There must be no other report element within the same report with the same code. The code is used to reference the report element from within a Template (see below). |
| Condition | An optional condition Expression; if it returns True or 1 the condition is considered to be fulfilled and the portion encapsulated by the condition element will be included in the report document. If it returns something other than True or 1 the portion encapsulated by the condition report element will be excluded. If you leave this property empty, the condition is considered to be always fulfilled. The condition expression is evaluated after the preparation Actions of the image element have been executed. |
| Preparation Actions | A list of Actions that will be executed before the condition element will be processed. |
| Fail On Filter Exception | Determines what shall happen if an exception occurs when executing a preparation action that performs a filter (e.g. because the value to which you want to filter does not exist). When enabled, an exception will be thrown and the report document creation will be cancelled; when disabled, the portion encapsulated by the condition report element will be excluded. |
Insertion
You can insert the placeholder for the condition element by dragging and dropping the report element from the content explorer of the Report Designer into the template. You will then see a start and an end tag for the condition element:
Condition Element Start Tag
[[<code>]]
Condition Element End Tag
[[<code>]]
Every content between the start and the end tag of the condition element will be removed from the report document, if the condition is not fulfilled or the condition element is excluded for any other reason. Take for example the following screenshot:

NOTE
If you change the code of a condition element after you have inserted the placeholder into the template, you need to change the start and end tag of the element in the template as well. Otherwise error messages will occur when creating the report document.
