SliderExtender控件

[tourist_tsl]

<ajaxToolkit:SliderExtender ID="SliderExtender1" runat="server"
Minimum="-100"
Maximum="100"
BoundControlID="TextBox2"
Steps="1" />
运行时有如下错误：The TargetControlID of 'SliderExtender1' is not valid. The value cannot be null or empty.
但是它根本就没有value属性

<asp:TextBox ID="TextBox3" runat="server" Text="123123"></asp:TextBox>
<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
<cc1:SliderExtender ID="SliderExtender1" runat="server" TargetControlID="TextBox3"
EnableHandleAnimation="true" BoundControlID="TextBox4">
</cc1:SliderExtender>
需要设置TargetControlID="TextBox3"属性.但是被设置了TargetControlID的控件,在画面上就看不到了(目前只限SliderExtender ).
