its simple

var vobj=document.getElementById("YourSilverlightObject");
    var mainCanvas=vobj.content.findName("RectangleID");
    var mainc=Convert.ToCanvas(mainCanvas);

    var sc=Convert.ToSolidColorBrush(mainc.get_background());
    bgcolor=sc.get_color();
    bgcolor=getFillColor(bgcolor);

//-------------------------------------------------------------------------------
//-------Color value convertor function
//-------Hexadecimal value from RGB Value
//-------------------------------------------------------------------------------
function getFillColor(color) {
   var fill = color;
   if (fill < 0) {
      fill = (16777216 + parseInt(fill));
   }
   fill = fill.toString(16);
   if (fill.length > 6) {
      fill = fill.substr(fill.length - 6);
   }
   while (fill.length < 6) {
      fill = "0" + fill;
   }
   fill = "#ff" + fill;
   return fill;
}

There is a thread on converting the color value you get here:

Nope... In VisStudio I see

Sender.Fill.toString() "SolidColorBrush" String

I did do this work around since I simply want to apply the color of another object ... I can use the long value... so,

var SndFill = Sender.Fill.Color

var TmpRct = '<Rectangle Canvas.Left="'+(XPos-10)+'" Canvas.Top="'+(YPos-10)+'" Width="'+SWd+'" Height="'+SHt+'" Fill="red" StrokeThickness="1" Stroke="blue" Opacity="0.35" IsHitTestVisible="false"/>';

this.TempBlock = this.control.content.CreateFromXaml(TmpRct); this.TempBlock.Fill.Color = SndFill;

.... this works but it bothers me that I can't get a hex value for the color .... seems to me to be a minor bug in the object model

What I'd like to do is (bold italic):

var TmpRct = '<Rectangle Canvas.Left="'+(XPos-10)+'" Canvas.Top="'+(YPos-10)+'" Width="'+SWd+'" Height="'+SHt+'" Fill=="'+SndFill +'" StrokeThickness="1" Stroke="blue" Opacity="0.35" IsHitTestVisible="false"/>';

But this fails because its a long number

By the way there's the same issue with Stroke

Sender.Stroke.toString() "SolidColorBrush" String

How to GET the color of FILL

I want to GET the color of the FILL of a Rectangle.... the object xaml

via script I want to get that color value and apply it to another object ... I can't find the way...

on mouse down I tried:

var SndFill = Sender.Fill
var TmpRct = '<Rectangle Canvas.Left="100" Canvas.Top="100" Width="50" Height="50" Fill="'+SndFill+'" StrokeThickness="1" Stroke="blue" />';

This fails and when I look at the text output for TmpRct I see Fill="SolidColorBrush"

Sender.Fill.Color gives a non hexidecimal, long number ... -500901

What's the solution...?
