Can anybody pls tell me the difference between
1.print when expression and text field expression of a textfield
2.Variable expression and initial value expression of a variable
Would u pls give a little example of both.Thanx.

Well I'll try...
1.) TextExpression of a TextField is WHAT is printed... so what Field value or if you use some more complex TextExpressions you could do something like:
1.) TextExpression of a TextField is WHAT is printed... so what Field value or if you use some more complex TextExpressions you could do something like:
| Code: |
"captiontext: " + $F{Field0815} + " / " + $F{Field0816}</td></tr></tbody></table><br />
<br />
2.) PrintWhenExpression is an expression of ANY Element to show/print it or not (so <b>WHETER </b>a field - or better an element - is printed).<br />
if the expression returns true it will be printed otherwise it won't be printed<br />
e.g. <table align="center" border="0" cellpadding="3" cellspacing="1" width="90%"><tbody><tr><td><b>Code:</b></td></tr><tr><td><pre>new Boolean($F{Field0815}.equals("SomeText"«»))</td></tr></tbody></table><br />
<br />
3.) a VariableExpression is an expression to calculate for example a field (e.g. the sum of Field0815)<br />
<br />
4.) a intitial ValueExpression is the value that the variable get BEFORE any calculation will happen. (so the initial value for some cases the VariableExpression won't be calculated and you don't want to see null but better BigDecimal.ZERO. <br />
if the variable is reset the initial value is set again (so for each page, group or whatever resettype you choose)<br />

Therefor you have to create a ConditionalStyle....
in iReport it's somewhere in menue (I'm at home now... so I guess to remember "Edit" --> "Styles"...)
Just create a Style "MyBorders" and add some conditions where you set the expression to your needs. You can add as many expressions as you want. For each condition you can set different element properties (colors/fonts/borders/whatever....)
At your textfield you just have to set that style in the properties.
it's quite simple

Well again:
if your PrintWhenExpression is:
if your PrintWhenExpression is:
| Code: |
new Boolean($F{Field0815}.equals("SomeText"«»))</td></tr></tbody></table><br />
<br />
and your Field0815 has "<i>SomeText</i>" as value... than the whole field is printed.<br />
<br />
if your Field0815 has "<i>OtherText</i>" as value... than the whole field is <b>not </b>printed. <br />
<br />
...<br />
this question I don't understand:<br />
<table cellpadding="0" cellspacing="0" align="center" width="525" bgcolor="#cccccc"><tr><td>How can I show my entire textfield with value on such condition.</td></tr></table><br />
<br />
Please describe a bit more in detail what you want to achieve.<br />

Brother I think u've already answered my question.By this-
I wanted to mean that depending on the passing text value("Sometext"),I want to show/hide my textfield.Actually I want to put a border around my textfield,then if $F{Field0815} matches "Sometext" the textfield will be shown,otherwise the textfield will not be shown.Can I do it?
