Hi to all,

Is it possible to change in a row the background of a unique cell ?

I've found examples for changing the background of a whole row but not
for a cell:

Thanks a lot for your help

You can set the background of a cell using the onCreate and
this.getStyle().backgroundColor = "blue";

I assume you want to do this based on a value in the control on the cell.

If you have a value in a data element called samplevalue in the cell and
you color the cell if this value is > 5,
then in the onCreate of the row you could.

if( this.getRowData().getExpressionValue( "row[SampleValue]" ) > 5 ){
yellowme = true;
}else{
yellowme = false;
}

define yellowme in initialize

yellowme = false;

finally on the chosen cell

if( yellowme ){
this.getStyle().backgroundColor = "Yellow";
}

I dont think this will work if you try to to set it on the getValue() of the
control, because by that time the onCreate has already been executed on the
cell.

I've found the solution ....
I've created a class which implements ICellEventHandler and applied it
to the specific cell in my rptdesign :

For example :

public class CellImpl implements ICellEventHandler {

public void onCreate(ICellInstance arg0, IReportContext arg1) {
try {
Object data = arg0.getData();
if (data != null) {
if ("".equals(data.toString().trim())) {
arg0.getStyle().setBackgroundColor("yellow");
}
}
} catch (Exception e) {
// TODO: handle exception
}
}

public void onPrepare(ICell arg0, IReportContext arg1) {}

public void onRender(ICellInstance arg0, IReportContext arg1) {}

}

Best regards

Dov
