Updatepanel not updating
In this walkthrough you will update part of a web page at a timed interval by using three ASP.NET AJAX server controls: the Script Manager control, the Update Panel control, and the Timer control.In addition to these issues, I know users have problems with Update Panel Triggers, User Controls in Update Panels, and Update Panels in Master Pages. NET AJAX docs to become familiar with the controls.Also, check out the AJAX Videos which discuss usage of not only the Update Panel but also the AJAX Control Toolkit.
This thing is quite simple when we are trying to update any control which is inside the updatepanel itself. We have one Button say Button1, which is also inside the Update Panel.As a result, users no longer see the whole page reload with every postback.This topic assumes that you are familiar with the , the outer panel is not refreshed when only the inner panel is triggered.The filter and the repeater have to be in the same update panel or you have to specify some triggers in code.Your best bet to get them to work together would be to wrap them in a webpart zone and set the update pane on the webpart zone. In our website we can't add the update panel to webpart zone because the Product Filter and the Repeater are in different webpart zones.
