Readonly Checkbox cell

Is there a way to put a readonly checkbox cell in the grid loading from a xml file?

You may use setDisabled method to block the checking of a checkbox: … etdisabled

or you may block it using the onEditCell event:

grid.attachEvent("onEditCell", function(stage,rId,cInd,nValue,oValue){
      return false; // block the edit operation
   return true; // allow the edit of the cell
