Hi
I have several html file with some form control and grid control. I want to attach it with a Window. How?
I have used like the following coding. But it shows blank as white space. Is anyone help me? 
function doOnLoad() {
dhxWins = new dhtmlXWindows();
dhxWins.enableAutoViewport(false);
dhxWins.attachViewportTo(“winVP”);
dhxWins.setImagePath(“…/…/dhtmlxWindows/codebase/imgs/”);
w1 = dhxWins.createWindow(“w1”, 20, 30, 320, 240);
w1.setText(“dhtmlxWindow”);
w1.button(“close”).disable();
attachURL();
}
function attachURL() {
w1.attachURL(“testgrid.html”, true);
}
