  Hi Luis,

  To restrict users to only select the data specified in the combo i[/i] list you can assign the DropDownStyle property of C1ComboBox equal to DropDownStyle.DropDownList.
  
  This way the text portion of the C1ComboBox will not be editable and the user cannot enter a value not existing in the drop down.

  Refer to the code snippet below

  c1ComboBox1.DropDownStyle = C1.Win.C1Input.DropDownStyle.DropDownList;
  

  Please find attached a sample implementing the same.

  Regards,
  
  Anand
