    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:
