My wrong form.
exception Microsoft JScript Runtime Error: ' Sys.Extended.UI ' is empty or not an object.
My method of modification
Put <asp:scriptmanager id= "ScriptManager1" runat= "Server" >
</asp:ScriptManager>
Switch
<ajaxtoolkit:toolkitscriptmanager id= "ToolkitScriptManager1" runat= "Server" >
</ajaxToolkit:ToolkitScriptManager>
validation controls
<ajaxtoolkit:autocompleteextender id= "Textbox1_autocompleteextender" runat= "Server"
Targetcontrolid= "TextBox1" minimumprefixlength= "1"
Scriptpath= "" Servicemethod= "Getcompletiondblist"
Servicepath= "Autocomplete.asmx" >
</ajaxToolkit:AutoCompleteExtender>
The above control is Microsoft's own, followed by the Ajax toolbox of controls.
Personally think it might be Microsoft's own control does not support Ajax Toolbox Autocompleteextender But after all, the same toolbox is supported.
So just replace that manager control.
Information:
the Toolbox;

The wrong form on the forum
I am using the ASP. NET AJAX Tooklit control, after dragging an AJAX control, the operation will interrupt the error,
Microsoft JScript Runtime Error: ' Sys.Extended.UI ' is empty or not an object.
What the hell is going on here?

To resolve this issue simply add combinescripts= ' false ' to the Ajaxtoolkitmanager tag, <asp:toolkitscriptmanager id= ' to olkitscriptmanager1″runat= "Server" combinescripts= "false" ></asp:ToolkitScriptManager>
<ajaxtoolkit:toolkitscriptmanager runat= "Server" id= "Ajaxscriptmanager" enablepartialrendering= "true" Combinescripts= "false"/>
