Hello,
I'm using the color picker control, and I seem to have a problem with setting the selected colour. If I set the selected color to the ARGB value (255, 173, 18, 15) in XAML using:
<Media:SfColorPicker SelectedColor="#FFAD0F12" HorizontalAlignment="Left" Margin="305,30,0,0" VerticalAlignment="Top" Height="225" Width="329"/>
the position of the selected color thumb appears to be in the wrong place. It's at the left of the color window when it should be at the right. This also happens when I set the selected colour programmatically. However, it doesn't happen with all colours, some seem OK.
I may be doing something stupid, but I don't know what. Thanks for any advice.
Hello,
I've attached an image showing the problem. On the left it shows the position of the thumb when I set the selected colour to (173, 15, 18) (a shade of deep red) programmatically or in XAML. On the right it shows the situation when I try to drag the thumb manually to the that colour value. The closest I could get manually was (173, 16, 19), but it can be seen that although the colour RGB values are almost identical the thumb is in two very different positions and the colours inside the thumb are very different. If I set the colour (173, 15, 18) in PaintShop Pro I get the colour under the thumb on the right of my images.

Hello,
It looks like its due to the fact that I was manually setting a width and height (see my original XAML). I've attached a modified version of your sample which now shows what I'm seeing.
Are there limitations of some sort on the width/height?

have logged a bug report and fix for this issue will be available in our next Service Pack release which is scheduled at the end of September 2013.
Please let us know if you have any queries.

Hello,
I was wondering if there's any information on whether the update with the fix for this issue is still scheduled to be released by the end of September?
Thanks

Hello,
There still appear to be remaining issues with the colour picker.
1. The colour (0, 0, 0) isn't accessible by dragging the thumb. Red never goes below 31 in the attached demo.
2. (possibly related to 1). The thumb keeps tracking when the mouse goes outside the control window. I have no problem with that, but the colours displayed are sometimes not correct, particularly when the mouse is outside and above the window.
I've attached the demo project updated with the latest assemblies to demonstrate.

Hi Robert,
Query 1:The colour (0, 0, 0) isn't accessible by dragging the thumb. Red never goes below 31 in the attached demo
We are able to reproduce the reported issue '0,0,0 color is not acquired using selectedcolor thumb'. We have logged a bug report and fix for this issue will be available in our upcoming service pack releases.
Query 2: The colours displayed are sometimes not correct, particularly when the mouse is outside and above the window.
Please mention whether you are referring problem is with 'Selectedcolor Thumb' or 'Hue thumb'. At the edge of the window we assign the color which is available at that point hence provide us the color you are mentioning and the snapshot which is displayed wrongly and provide is more information on this issue. So that it will be helpful for us to check and provide you accurate solution.
Please let us know if you have any queries.

Hi,
For the second point, I'm referring to the selected colour thumb. I've attached a very short movie file showing what I mean.

Hi,
Do you have any information on when the service pack with a fix for this issue will be available?
Thanks,

Hi Vignesh,
Thanks for the update. I've now released my app, so if there's going to be a release fixing both issues before the end of the year, I'll wait until then to update it.
Robert
