Yes, you have to do it field-by-field, recursively into all containers. My Process All Fields script can help you with that.

How can we set the background color of all the fields in a particular subform based on a dropdown value.
Do we need to go field by field or do we have a script to access all fields in a subform with nested subforms.

Thanks

Setting a fill on a circle or rectangle is a little tricky. In this case, the XFA object will look like this (for a circle or rectangle):

<draw>
    ...
    <value>
        <arc|rectangle>
            ...
        </arc|rectangle>
    </value>
</draw>

When setting a solid fill, you need to set the following XFA structure inside the <arc> or <rectangle> value type node:

<fill presence="visible*">
    <color>R,G,B</color><-- start -->
    <linear type="toRight*|toLeft|toTop|toBottom">
        <color>R,G,B</color><-- end -->
    </linear>
</fill>

(* = default)

The problem is that, initially, none of those nodes exist so you need to create them.

Here’s a sample script that sets a linear to-right fill on a circle object:

// JavaScript:

// create start color
var startColorNode = xfa.form.model.createNode("color");
startColorNode.value = "255,0,0"; // red

// create end color
var endColorNode = xfa.form.model.createNode("color");
endColorNode.value = "255,255,0"; // yellow

// create linear node for fill type
var linearNode = xfa.form.model.createNode("linear");
linearNode.type = "toRight"; // start on left, end on right
linearNode.nodes.append(endColorNode); // add end color

// create fill node for arc (circle)
var fillNode = xfa.form.model.createNode("fill");
fillNode.nodes.append(startColorNode); // add start color
fillNode.oneOfChild = linearNode; // add fill type

// remove old arc fill (if any) and set new one
if (Circle1.value.arc.resolveNode("#fill"))
{
    Circle1.value.arc.nodes.remove
    (
        Circle1.value.arc.resolveNode("#fill")
    );
}
Circle1.value.arc.nodes.append(fillNode);

For a radial fill, you need to set the following XFA structure inside the <arc> or <rectangle> value type node:

<fill presence="visible*">
    <color>R,G,B</color><-- start -->
    <radial type="toEdge*|toCenter">
        <color>R,G,B</color><-- end -->
    </linear>
</fill>

(* = default)

The code would therefore be very similar to the example above, creating a new radial node rather than a linear node.

For the solid fill case, the XFA structure is much simpler:

<fill presence="visible*">
    <color>R,G,B</color><-- start -->
</fill>

How do you reference the visual properties of non-interactive objects in Adobe LC Designer?

I need, for example, to fill a circle (or rectangle) in solid, linear, or radial format (with start and end colors).

Actually, I had the show/hide solution working and thought there might be a more elegant solution to accomplish the same thing.

Unfortunately, you can’t change the object at runtime. The best you can do is show/hide the appropriate object or use the instance manager to add/remove the appropriate subform that contains the object you want to use (better for data binding).

Is it possible to change object type for instance textfield to drop-down list at runtime?

Thank you for your help.

I appreciate your efforts and time with trying to help me solve this. We will have to just live with the colors being printed until i can come up with something else but if you think of anything else i would appreciate more input. thanks again.

Sorry, I just tried out that script and also referenced the LC Designer Reference document and it looks like a fill can’t be given a relevant property – sorry!

The script I gave earlier only removed the border’s edge (I assumed it applied to all of the border’s child objects and therefore the edge and the fill would not be printed).
