this have (allradcontrols return me radsplitter, radpane ans radbuttons master page)

 function disablesave(habilita, botao) {                     var btsalvar = $find(botao);                     if (btsalvar != null) {                         var allradcontrols = $telerik.radcontrols;                         if (habilita == "true") {                             btsalvar.set_enabled(true);                             $("#<%=pnlprincipal.clientid%>").find("input,a,textarea,table").attr("disabled", false);                         }                         else {                             btsalvar.set_enabled(false);                             $("#<%=pnlprincipal.clientid%>").find("input,a,textarea,table").attr("disabled", true);                         }                     } 

radcombobox exposes array @ client-side contains radcombobox instances. array can accessed like:

telerik.web.ui.radcombobox.comboboxes

for example:

if radcombobox controls embedded in control, can these controls array described above.

here example of radcombobox nested inside grid:

<telerik:radgrid id="radgrid1" runat="server" ...>         ...          <edititemtemplate>             <telerik:radcombobox id="radcombobox1" runat="server"></telerik:radcombobox>             <telerik:radcombobox id="radcombobox2" runat="server"></telerik:radcombobox>             <telerik:radcombobox id="radcombobox3" runat="server"></telerik:radcombobox>         </edititemtemplate>    ... </telerik:radgrid> 

and here javascript code:

<script>     function pageload() {         var combo1 = telerik.web.ui.radcombobox.comboboxes[0];         var combo2 = telerik.web.ui.radcombobox.comboboxes[1];         var combo3 = telerik.web.ui.radcombobox.comboboxes[2];     } </script>
