Created Unassigned: colorpickerextender not doing anything [27669]

Hello,
I am trying to use the ajax colorpickerextender my code is below when I run the page I get No errors but when I click on the textbox nothing happens. the color chooser never pops up. I can type in the textbox and it works like any other textbox. I have tried this on chrome, internet explorer and firefox all with the same results
```
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>


<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:ColorPickerExtender ID="TextBox1_ColorPickerExtender" runat="server" Enabled="True" TargetControlID="TextBox1">
</asp:ColorPickerExtender>
```
