[tooltip] Tooltip in UserControl with an UpdatePanel disappears

[klogan]

I am using the tooltip from ​http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/ in .NET, inside of a UserControl. The UserControl has an UpdatePanel inside of it that is triggered by a button. After clicking the button and causing the AJAX update post back, the tooltips are not displayed. The events are firing, but there is a problem in the javascript code for this situation.

1. after the AJAX postback, in the update function, the current property is null, so the function returns and no tooltip is then displayed.

To fix this I added two fixes (see the attached file and search for custom).

1. I added this to the $.fn.extend function - this.each(function() {

custom

if (((typeof(this.toolTipText) == "undefined")

this.toolTipText == "") && this.title != "") {

this.tooltipText = this.title;

}

2. I needed to force the helper class to be recreated, so in the createHelper function I added this:

custom if (helper.parent) {

helper.parent = null;

}

Using these fixes/hacks will lose some of your performance gains from checking for the helper.parent and reusing (instead of recreating it), so there might be better way of addressing this issue. The scenario could be quite common for .Net developers, but not for other language developers. Is it worth putting in the trunk of the code?
