Middle Range thumb always visible

[Yen-Sheng]

I would like to have all three of my thumbs visible at any given time.
I have 0 to 10 for my data set but I would like to move the slider across like a non-ranged slider by grabbing the middle thumb. So I've set a minimum size on the middle thumb to be 8. 
However, this was back before the template structure changed to 2012. Now, after much shifting around, I've gotten it to look like what it used to look like with a always visible middle thumb. 

When I drag the thumb around, it works just fine, except when I drag the thumb all the way to the end of the scale, it throws the following

Error: Unhandled Error in Silverlight Application 
Code: 4008    
Category: RuntimeError       
Message: Layout cycle detected.  Layout could not complete.     
MethodName:      

(note, there is no method name).
It also does the same thing when I move the left thumb towards the right thumb such that range = 0.

Hi Yen-Sheng,

From your description it seems that you've defined custom style and logic for the control. Can you please send us a sample project where we can test your scenario as I can't reproduce it in a sample application using our latest official assemblies. Also can you tell us the RadControls version you're using? With previous versions of the RadSlider control there were similar scenarios where a Layout Cycle Detected exception was thrown but this issue is already fixed.

Thank you in advance for your cooperation.

Kind regards,

Hummm... I tried it in a new application and it didn't throw the error. You're right that it may be something I'm doing.

But there is the base problem of having the ability to use the middle range thumb for single drag. 
Here's my code for enabling the middle range thumb to be shown on default.

Internally, I believe that you're setting the "RangeMiddleThumb" width property to reflect the dragged size or something like that?

Hello,

The middle (range) thumb's size is used for calculations of the value as well as positioning the other thumbs. I would not recommend setting the min width property. Instead, you can use the MinimumRangeSpan property, which will ensure you a minimum range of the end thumbs - therefore the middle thumb will be visible. Please let me know if that is acceptable in your scenario.

All the best,
