[CLOSED] Check all checkbox for TreeGrid

[bakardi]

I have extended TreeGrid to show checkboxes (TreeGridNodeUI renderElements). Now I want to add check all checkbox to the header. Could you please give some advise where to find right method to override (something like renderHeaders).

Hi,

Headers template is within the initComponent function.

You can find TreeGrid sources here:
<Ext.NET sources root>\Ext.Net\Build\Ext.Net\ux\extensions\treegrid \treegrid.js


You will probably need to also override the handleHdDown function.
