Q. How can we open a new modalwindow from another opened modal window(urlattach approach) ?
You can use the following approach:
var w2 = parent.dhxWins.createWindow(“w2”, x,y, width,height);
w2.setModal(true);
where dhxWins is dhtmlxWindow object that was initialized in the parent window
How to close parent popup window without closing child windows.
If you mean that you want to close dhtmlxwindow and don’t close dhtmlxwindow inside its iframe, it isn’t possible.
