Extjs Grids with Locked columns, columns missing in grid.columns property

I have a ExtJs Grid with two left most columns locked, Now I have listener which cycles through all the columns of a grid and updates the header information.

var grid = this.grid
var columns = grid.columns;
for(var i=0;i<columns.length;i++)
  {
//do something with columns[i];
}

This used to work previously but now after locking columns it no longer works as expected.

Extjs Locked columns feature changes how the grid is stored in the Extjs Application tree.

Suppose you have a grid of 5 columns and you lock leftmost 2. Then Extjs internally divides your grid into two grids having 2 and 3 columns respectively. Therefore your code should be :

var grid = this.grid.items.items[0];
var columns = grid.columns;
for(var i=0;i<columns.length;i++)
  {
//do something with columns[i];
}

var grid = this.grid.items.items[1];
var columns = grid.columns;
for(var i=0;i<columns.length;i++)
  {
//do something with columns[i];
}
