Conditions in Ireport

[bigelo]

Hello.

 

I am new with IReport so I hope that sb can help me.

 

How is it possible to use conditions in IReport.

 

Example:

 

I have two parameters. "Param1" is boolean and "Param2" is a String.

Now I only want that the value of Param2 is shown in the report only when Param1 ist true!!! (Sounds very simple ;) )

 

How can I do this (textfield expression)?

 

Thx a lot

Code:

Param1 ? Param2 : ""

bigelo,

 

Use the IF-ELSE ternary operators:

 

Code:

condition ? statement1 : statement 2

 

Explanation:

IF condition is true, statement1 is executed

ELSE statement2 is executed.

 

The statement given by kaunietiss is exactly the way you should interpret the example you gave.

Code:

[code] Param1 ? Param2 : ""

 

The statement above has the same effect as...

 

Code:

[code](Param1 == TRUE) ? Param2 : ""

 

You normally would use this in Print when expression.

You could also use the statement in the middle of static text or in a text field.

This is very useful as you most likely will need it in many of the reports that you will be making.
