You can use next syntax in XML
    <column id=“level1” width=‘100’ type=‘ro’> Level1

And later in javascript
    var pos=grid.getColIndexById(‘level1’)


Thank you for your Information…



 



 If suppose the Headers are Dynamic one…



Can I  check whether the Column Header is Exists or Not…



 



For Example the Level is from 1 to 10



Suppose I check is Level11 is exists or not…



Please provide some solution for this.



 

You can get count of columns as
    grid.getColumnCount();

If you need to check existence of some column , you can use approach described above

  var pos=grid.getColIndexById(‘level11’)
  if (typeof pos == “undefined”) alert(" level11 doesn’t exists ");
