解决方案

OK，所以问题是jQuery $（document）.ready（）事件在updatepanel异步回发中没有被触发，解决方案是将ready（）中的函数定义重构为显式函数定义（函数pageReady（）{...} ），并将新的pageReady（）事件处理程序添加到ASP.net Sys.WebForms.PageRequestManager endRequest 事件，该事件仅在异步回发时触发。所以现在的代码如下所示：

  Sys.WebForms.PageRequestManager.getInstance（）add_endRequest（pageReady）; 
 $（document）.ready（pageReady）; 
 
函数pageReady（）{
 ... 
 oAutoCompleteTextBox = GetElement（'<％= this.AutoCompleteTextBox.ClientID％>'）; 
 ... 
 SetupDefaultValues（）; 
 
 
函数SetupDefaultValues（）{
 ... 
 if（canFocus（oAutoCompleteTextBox））{
 oAutoCompleteTextBox.focus（）;

The issue is now resovled :) Thanks for everyone's help and attention!

I'm getting the JS error "Unexpected call to method or property access" in IE6 intermittently on the line "oAutoCompleteTextBox.focus();".  Hopefully, someone has seen this issue before and can provide some insight on how to solve it.  Below is the context of the usage.  
$(document).ready(function () {
    ...
    oAutoCompleteTextBox = GetElement('<%=this.AutoCompleteTextBox.ClientID%>');
    ...
    SetupDefaultValues();
}

function SetupDefaultValues() {
    ...
    if(canFocus(oAutoCompleteTextBox)) {
        oAutoCompleteTextBox.focus();
    }
}

解决方案
OK, so the issue was that the jQuery $(document).ready() event isn't fired on updatepanel async postbacks.  The solution is to refactor the function definition inside the ready() into an explicit function definition (i.e. function pageReady(){...}) and add the new pageReady() eventhandler to ASP.net Sys.WebForms.PageRequestManager endRequest event which is only fired on async postbacks.

So the code now looks like this:
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(pageReady);
$(document).ready(pageReady);

function pageReady() {
    ...
    oAutoCompleteTextBox = GetElement('<%=this.AutoCompleteTextBox.ClientID%>');
    ...
    SetupDefaultValues();
}

function SetupDefaultValues() {
    ...
    if(canFocus(oAutoCompleteTextBox)) {
        oAutoCompleteTextBox.focus();
    }
}
Thanks for everyone's help and attention - took a while to figure out, I'm just glad it's resolved :)
