setRowExcellType problem

When trying to apply the setRowExcellType method I receive the following error:

Uncaught TypeError: Cannot read property 'childNodes' of undefined
 dhtmlXGridObject.setRowExcellType @ dhtmlx.js:9
(anonymous function)	@ griddemo.html:47

I am including demo files and as you can see by them, I tried setting the method before and after the grid init and load.
I have tried this with setRowColor also with the same results. What am I doing wrong? (1.26 KB)

A little more explanation on what I’m wanting to achieve.

As you can see by the demo file, I set my grid excell types by the column initially. I want to maintain these types throughout the grid with the exception of select row(s).

On these row(s) I would like to disable the excell types and make the cells in them read only.

Thank you,

You should call the setRowExcelltype() method after the data is loaded:

myGrid.load('demo.xml', function(){ myGrid.setRowExcellType('1000','ro'); });

That works. Thank you.
