Browser differences

if (HostBrowser[0] == “IE” || HostBrowser[0] == “Firefox”) {
TslGrid.setStyle("",“font-weight:bold;”,"","");
}

Setstyle, like above, does not work in Opera and Chrome ( reason of the if clause ).
It leads to error on upload.

Any suggestions of work arounds?

Try to change command line as
TslGrid.setStyle("",";font-weight:bold;","","");

With such css code it must work in all browsers
