Question

I have a usercontrol wich is visible=false when the page is loaded.
Then, it becomes visible=true.
I want some javascript to be executed when this usercontrol is set to visible=true in the code-behind.
the only solution i found is to use ScriptManager.RegisterStartupScript in the

usercontrol’s code behind.
But i don’t like writing my javascript in the codeBehind.

This jQuery in the usercontrol doesn’t work :
$(document).ready(function() {
alert(‘test’);
});

The usercontrol is into an updatepanel.

Try this jQuery plugin. It makes use of the onpropertychange event in IE and the DOMAttrModified mutation event in supported browsers. With it, you should be able to watch for the visibility property being changed.
