TabContainer使用过程中混肴滚动位置问题

>>Issue:

I have a 3 tab panels in a tab container in the middle of the page. The problem is that when the page loads the first tab panel gets focus and the page is scrolled to that position.

Looking at the latest AJAX Souce code from December, I noticed that the _app_onload function forces the focus to the active tab.  I believe this is occuring upon every postback.  Before I muck around with the source, I wanted to see if there was a reason for this.

Since posting this I commente out the "activeTab._setFocus(activeTab);" line.  It works in multiple browsers; just not IE8, which is what my organization is current stuck on.  Still looking for a solution to the Scroll Position.

>>Solution:

<ajax:ToolkitScriptManager ID="scriptmanager1" runat="server"></ajax:ToolkitScriptManager>
    <script type="text/javascript">
        Sys.Extended.UI.TabContainer.prototype._app_onload = function (sender, e) {
            if (this._cachedActiveTabIndex != -1) {
                this.set_activeTabIndex(this._cachedActiveTabIndex);
                this._cachedActiveTabIndex = -1;

                var activeTab = this.get_tabs()[this._activeTabIndex];
                if (activeTab) {
                    activeTab._wasLoaded = true;
                    //activeTab._setFocus(activeTab);     // the only change made to this prototype
                }
            }
            this._loaded = true;
        }
   </script>
