Hi Hugues,

Thank you for contacting us. 

Yes, you can set the Minimum property to negative number. Here is the code snippet: 

this.radTrackBar1.Minimum = -20;
this.radTrackBar1.Maximum = 20;
this.radTrackBar1.Value = 0;

Please refer to the attached sample demo and image which demonstrates you the code and the result.
 
Should you have further questions, I would be glad to help. 

Regards,
