You can use next syntax in XML
    <column id="level1" width='100' type='ro'> Level1 </column>

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 ");
