Hi, guys! Who knows how to iterate over the grid columns. I need this method in order to get columns attributes (such as width, visibility - hidden or not). Now I use this method like this.




var columns = grid.headerCt.getVisibleGridColumns(false);

var fn = function (item, index, all)
{

//for ex. I get width attribute
colwidth = this.width;

}

Ext.each(grid.columns, fn);



But this method works only with "first-level" columns. If a grid has some grouped headers, the method does not iterate over sub-headers. Let me give you a concrete example. I have a grid like below and using this method I can get attributes of the "first-level" columns and can't reach attributes of subcolumns... Really need help. Many thanks!

So, if there is an alternative or an extension of "Ext.each" method, that will do what is expected?

I got it! This piece of code works fine.




var cls = grid.headerCt.getGridColumns();

var i = 0;

var ln = cls.length;

while(i<ln){

if(grid.headerCt.getHeaderAtIndex(i)) {

//for ex. I get width attribute

colwidth = grid.headerCt.getHeaderAtIndex(i).width;

}

i++;

}
