  My apologies if this has come up before but when using the ShowIcon mode is there a way to make this work properly with No colour?
  
  If I select no colour then the colour shown in the Icon is white - not the nothing icon (checked background with a red line through it).  I appreciate the fact that it does work behind the scenes but visually this is very misleading to the user.
  
  When opening a form how do I know which are set to white and which are set to no colour?  This wouldn't be so much of a worry if when clicking the icon you could tell if white or no colour is picked but you can't - there is no indication whatsoever which is the active colour.
  
  Does anyone know of a work around and can this be added as a bugfix or improvement (depends on your viewpoint but I regard as a bug).
  
  Best Regards,
  
  Jon

  Further to my comment yesterday I've had to implement the result of changing a colour in a grid - to that end i just used a div and coloured the background accordingly,  then for an empty colour I reused the transparent image as the background-image.
  
  Looking at the css it looks like there is a distinct rule for this, could something be added to the OnClientColorChanging event to change the rule to show an image instead of the background-color style (css tag seems to be .RadColorPicker .rcpIcon em)
  
  It would be nice to have this built in but for now a work around would be helpful
  
  Regards,

  Hello Jon,
  
  Thank you for your suggestion about the color preview when the RadColorPicker's ShowIcon property is set to true and No Color is selected. It will be brought to the attention of our developers and the feature's implementation will be discussed.
  
  Currently, such effect could be achieved by modifying the CSS styles of the control on its client event OnClientColorChange, as you have correctly guessed. For your convenience I have prepared a sample project, demonstrating this solution. Please use it as a reference for achieving the desired effect into your actual project.
  
  Kind regards,
  Slav

  Slav,
  
  You're a star!  That works perfectly and it looks much better than having the white.  
  
  If anyone else uses this you'll need to use the same function call for the OnClientLoad event of the colourpicker - otherwise it starts off white...
  
  Thanks again Slav,
  
  Best Regards,
  
  Jon
