Hello Marian,
I have tried the following code and which worked as expected.

<telerik:RadComboBox ID="RadComboBox1" runat="server" Width="250px" ShowToggleImage="True">
 <ItemTemplate>
  <telerik:RadTreeView runat="server" CheckBoxes="true" ID="RadTreeView1" Width="100%" Height="140px">
    <Nodes>
      <telerik:RadTreeNode runat="server" Text="Australia">
        <Nodes>
           <telerik:RadTreeNode runat="server" Text="South East Australia">
               <Nodes>
                  <telerik:RadTreeNode runat="server" Text="Sydney">
               </telerik:RadTreeNode>
               <telerik:RadTreeNode runat="server" Text="Melbourne">
               </telerik:RadTreeNode>
               </Nodes>
        </telerik:RadTreeNode>
     </Nodes>
    </telerik:RadTreeNode>
</Nodes>
 </telerik:RadTreeView>
 </ItemTemplate>
     <Items>
        <telerik:RadComboBoxItem Text="" />
     </Items>
</telerik:RadComboBox>
<asp:Button ID="Button1" runat="server" OnClientClick="return UnCheckAll();" Text="UnCheckAll();" />

Javascript:

function UnCheckAll()
{
 var treeview=$find("<%= RadComboBox1.Items[0].FindControl("RadTreeView1").ClientID %>")
 treeview.uncheckAllNodes()
}

Thanks,
Princy.

Hello Marian,

For more details on the code that Princy has provided, you could take a look at the following two help articles:
