  How to GET the color of FILL

  Sep 19, 2007 03:17 PM | LINK

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

  <Rectangle X:Name="Test" Fill="#FFF85B5B" />

   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...?

  does fill.tostring() work?

  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

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

   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;
  }
