Detecting crtl + click on a checkbox in TreeGrid

Suite and Optimus Suite 5
#1

Hello,

I have code written that displays a tree grid. The tree may have several levels all of which have check boxes in the first column. The code below causes all the child nodes under a parent to be (un)checked when the parent node is (un)checked.

Is it possible to detect a ctrl + click so that I can avoid (un)checking all child nodes? It seems that the API does not allow me to detect this with the given parameters.

Thanks,
Mike

It looks like the functionality I’m looking for is available on the dhtmlxmenu here: docs.dhtmlx.com/doku.php?id=dhtm … boxclick&s[]=attachevent&s[]=oncheckbox.

Does anyone know how to replicated this functionality for the TreeGrid onClick event?

Sorry, here is the link: http://docs.dhtmlx.com/doku.php?id=dhtmlxmenu:event_oncheckboxclick&s[]=attachevent&s[]=oncheckbox

Unfortunately it impossible to detect if check box has be clicked with ctrl button pressed. As a workaround you can create custom “ch” eXCell type which will handler this. docs.dhtmlx.com/doku.php?id=dhtm … creation&s[]=custom&s[]=excel

Thank you Olga. I will look into the link you have provided. At least I know that it is possible.
