updatepanel

Is there a workaround for IE 6/7 “Unspecified Error” bug when accessing offsetParent

I’m using jQuery UI’s draggable and droppable libraries in a simple ASP.NET proof of concept application. This page uses the ASP.NET AJAX UpdatePanel to do partial page updates. The page allows a user to drop an item into a trashcan div, which will invoke a postback that deletes a record from the database, then rebinds the list (and other controls) that the item was drug from. All of these elements (the draggable items and the trashcan div) are inside an ASP.NET UpdatePanel.

Adding PostBackTriggers and AsyncPostBackTriggers to UpdatePanel for dynamically-generated grandchild controls

I have a page with a ScriptManager, a generic HTML drop-down list (<select>), and an UpdatePanel. The UpdatePanel contains a PlaceHolder (for now). During Page_Load, a number of user controls are added to the PlaceHolder (really, it’s several instances of the same user control). The number to add is not known until the page loads, so they do need to be loaded dynamically. The drop-down list is populated with the same number of menu items, and there is javascript on the page also (using jQuery) to show only one of the controls at a time depending on the state of the drop-down list.
