I have a datalistparent and a datalistchild . Inside the datalistchild itemtemplate, I have checkboxes. When the user clicks on a checkbox then all checkboxes inside that datalistchild should be disabled. all in server side code. I have attached the html and .vb code. Please help. Thanks

 Protected Sub Value_Clicked(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim chk As CheckBox = DirectCast(sender, CheckBox)
        Dim intValueID As Integer = DirectCast(chk.Parent.FindControl("lblAttributeValueID"), Label).Text
        Dim intNameID As Integer = DirectCast(chk.Parent.FindControl("lblAttrNameID"), Label).Text
        If chk.Checked Then
            AddNavigationProductFilter(intNameID, intValueID, True)
            'here diable all checkboxes in this particular item template (dlAttributeValues)
        Else
            AddNavigationProductFilter(intNameID, intValueID, False)
            'here enable all checkboxes in this particular item template (dlAttributeValues)
        End If
        BindProductFinderItems()
    End Sub


    <div class="Attributes">
<asp:DataList ID="dlAttributes" runat="server" RepeatDirection="Horizontal" RepeatColumns="3" Width="100%">
<ItemStyle Width="33.3%"/>
    <ItemTemplate>    
    <asp:Label ID="lblAttributeNameID" runat="server" Visible = "false" Text='<%# DataBinder.Eval(Container.DataItem, "ID")%>'></asp:Label>
        <span style="color:#58595B;font-size:14px;font-weight:bold;"><%# DataBinder.Eval(Container.DataItem, "ShortName")%></span>    
        <div style="height:100px;overflow:auto; border: 1px solid #CACACA;margin:10px 10px 10px 0px;padding:10px;">
           <asp:DataList ID="dlAttributeValues" runat="server">
              <ItemTemplate>
                    <asp:Label ID="lblAttrNameID" runat="server" Visible = "false" Text='<%# DataBinder.Eval(Container.DataItem, "AttributeNameID")%>'></asp:Label>
                    <asp:Label ID="lblAttributeValueID" runat="server" Visible = "false" Text='<%# DataBinder.Eval(Container.DataItem, "AttributeValueID")%>'></asp:Label>
                    <asp:checkbox ID="chkValue" runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"AttributeValue")%>' AutoPostBack="true" OnCheckedChanged="Value_Clicked"/>
                </ItemTemplate>
            </asp:DataList>
