predefine a value in a datagrid field on edit

[jaimi]

How can I set a defined value to a numberbox and a combobox when the row switches to edit-mode?
I tried this but doesn't work:

Code:

 ,{field :'CUR_CDE',title:'Währung',width:090,sortable:'true',align:'left'
	  ,editor  : {
        type   :'combobox'
	   ,options:{
	      valueField:'CUR_CDE'
	     ,textField:'CUR_DES'
		 ,url:'pferd.lkp.cur.json'
		 [b],value:'EUR'[/b]
		 ,required:true
		 ,editable:true
		 ,prompt:'Währung...'
		 ,missingMessage: 'Wählen Sie die Währung aus.'
       }//Options
      }//editor
    }//field

Code:

   ,{field:'HTH_GESAMT',title:'Gesamt',width:070,sortable:'true',align:'left'
      ,editor:{ type:'numberbox'
              ,options:{ required:true
			            ,prompt:'Gesamt-Preis...'
			            ,missingMessage:'Geben Sie den Gesamt-Preis für die Behandlung ein.'
						,precision:2
						,decimalSeparator:'.'
						[b],min:0[/b]
						,max:10000
						[b],value:0.00[/b]
					   }
	  }//editor
    }//field

You have to change this value when beginning to edit a row.

Code:

onBeginEdit: function(index,row){
  var ed = $(this).datagrid('getEditor',{index:index,field:'listprice'});
  $(ed.target).numberbox('setValue', 100);
}

It works in general. But I can not longer put the decimal point where in the field-options set.
How to define the options for this element?
