User control updatepanel not updating

NET AJAX Control Toolkit is not just a control but a whole framework to add animations to a control.For the contents of an Update Panel, a special extender exists that relies heavily on the animation framework: Update Panel Animation. One has a Drop Down and another Update Panel with content.How can I trigger update to the Update Panel by the Drop Down's selected Item Changed event when they are in different Content Placeholders?

Two objects used to draw the rectangles are then created: a Bitmap and a Graphics object.

property to image/jpeg, so that the entire page will be rendered as a JPEG image.

The code then calls the Clear method to ensure that no extraneous content is sent with this response.

The variables created in the page are used as coordinates to draw the rectangles and a string that appears inside the largest rectangle.

When the three rectangles and the string that appears inside them are drawn, the Bitmap is saved to the Stream object that is associated with the property and its format is set to JPEG.
