Lines in text boxes

This is a situation which has been around for a long time.

One approach is to create those writing lines as part of the contents of the form (in other words, in the layout software). So, if the user prints the blank form, he has the writing lines.

Now, if the form is filled on screen, those writing lines are more an annoyance than useful. And they are not needed, because text in a field will always be well aligned.

With a little bit of JavaScript, we can have both options. In the Format event, you could add the following custom script:

if (event.value.toString().length > 0) {

event.target.fillColor = color.white ;

} else {

event.target.fillColor = color.transparent ;

}

If there is something in the field (the length of its value as string is greater than 0), the background of the field is white, and covers he writing lines. Otherwise, the background is transparent, and the lines are visible.

Hope this can help.
