Hi,
I noticed that there is no way to load the buttonCombo in a ribbon even though it is based on a combobox so I thought I might help others out who need the functionality as I did.
In dhtmlx.js you need to add a couple of lines.
Look for
remove:function(a){if(a.combo instanceof dhtmlXCombo){a.combo.unload();a.combo=null}},
and add
loadButtonCombo:function(a,c){if(a.combo instanceof dhtmlXCombo){a.combo.load(c);}},
just behind it. Then look for
dhtmlXRibbon.prototype.setValue=function(g,c){var a=this._items[g];if(this.items[a.type]&&typeof(this.items[a.type].setValue)=="function"){this.items[a.type].setValue(a,c)}};
and add
dhtmlXRibbon.prototype.loadButtonCombo=function(g,c){var a=this._items[g];if(this.items[a.type]&&typeof(this.items[a.type].loadButtonCombo)=="function"){this.items[a.type].loadButtonCombo(a,c)}};
just behind it.
Now you have:
myRibon.loadButtonCombo(“itemId”, “some URL goes here”);
The values can be in xml or json format. From here it is easy enough to prototype the callback as well.
Cheers,
Alex
