I'm trying to Clear a RadComboBox in javascript, and have it post back (when AutoPostBack is enabled). I've been searching around for a solution, and this is the best I can come up with - but it feels incredibly hacky - is there a more appropriate method of doing this?

var combo = $find(comboId);
combo.hideDropDown();
combo.trackChanges();
combo.clearSelection();
combo.commitChanges();
var f = { Command: "Select", Index: combo.get_selectedIndex() };
combo.postback(f);

Thanks
Fergal

Hello Fergal,

Regarding the clearing of the RadComboBox, the used approach is the correct one. As for having the RadComboBox to artificially fire a postback, this is however consider as a hack, therefore, it is possible to pally the custom approach you are currently using.
