Get which UpdatePanel is updating at the server side. Check these links:</p> <blockquote> <p><a class="" href="http://msdn2.microsoft.com/en-us/library/system.web.ui.updatepanel.isinpartialrendering.aspx">UpdatePanel<span class="cs">.</span>IsInPartialRendering Property</a> </p> <blockquote> <p>Gets a value that indicates whether the <a id="ctl00_rs1_mainContentContainer_ctl03" href="http://msdn2.microsoft.com/en-us/library/bb359258.aspx">UpdatePanel</a> control is being updated as a result of an asynchronous postback.</p> <p>The <span class="selflink">IsInPartialRendering</span> property is intended for use by control developers who want to know when an <a id="ctl00_rs1_mainContentContainer_ctl28" href="http://msdn2.microsoft.com/en-us/library/bb359258.aspx">UpdatePanel</a> control is being updated as a result of an asynchronous postback. </p></blockquote> <p><a href="http://forums.asp.net/t/1151141.aspx"><font color="#5403fa">Which UpdatePanel issued an Async Postback Call?</font></a></p> <p><a href="http://forums.asp.net/t/1056213.aspx"><font color="#034efa">how to get which UpdatePanel has posted</font></a></p></blockquote> <p>2. use try... catch to catch errors, and in catch block, create an new&nbsp;exception which contain information of which updatepanel is updating and throw it.</p> <p>3. check the information in the error at the client side, process the error based on the information</p> <p>If you have further questions,let m eknow!</p> <p>Best Regards,<br /></p>http://forums.asp.net/thread/2164047.aspxSun, 10 Feb 2008 10:54:10 GMT4c671506-2930-414c-a40b-8bf57ded5924:2164047MNFMNF0http://forums.asp.net/thread/2164047.aspxhttp://forums.asp.net/commentrss.aspx?SectionID=1007&PostID=2164047<p>I &nbsp;have an ASP.NET AJAX page with several UpdatePanels. If error occured during asyncronous postback, I want to ignore it for some UpdatePanels and show errors for other UpdatePanels . The samples that I found(like&nbsp;&nbsp;<a href="http://www.asp.net/AJAX/Documentation/Live/tutorials/CustomizingErrorHandlingforUpdatePanel.aspx">Customizing Error Handling for ASP.NET UpdatePanel Controls.</a>) suggested to call <span style="COLOR:#006600;"><a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.WebForms/PageRequestManagerClass/PageRequestManagerEndRequestEvent.aspx">add_endRequest</a> and from <a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.WebForms/EndRequestEventArgsClass/default.aspx">EndRequestEventArgs</a>&nbsp;</span>&nbsp;use <a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.WebForms/EndRequestEventArgsClass/EndRequestEventArgsErrorProperty.aspx">error Property</a>&nbsp; .</p> <p>My question is how can I find which of UpdatePanels caused the particular Request in EndRequestHandler? </p> <p>I found&nbsp;an idea in comments of <a href="http://smarx.com/posts/how-to-handle-a-timeout-in-an-async-postback.aspx">How to handle a timeout in an async postback</a>&nbsp;to use <a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.WebForms/EndRequestEventArgsClass/EndRequestEventArgsResponseProperty.aspx">response Property</a> (<a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.Net/WebRequestExecutorClass/default.aspx">Sys.Net.WebRequestExecutor</a> class.) Then I can access <a href="http://www.asp.net/AJAX/Documentation/Live/ClientReference/Sys.Net/WebRequestExecutorClass/29f9ec8a-adc2-4d52-a831-fc0956c01099.aspx">webRequest Property </a>, but what to do next?</p>
