Thank you, you saved me a lot of time!

Just one comment - this only works if the eventName is the clientId of the control, not the Id... Also, I did prm._doPostBack instead - otherwise it was still doing a full postback.

Cheers!

Great solution; One thing though - If the UpdatePanel's UpdateMode is set to Conditional, a server side call to myUpdatePanel.Update(); is needed, or else the partial page postback won't be visible on the client side.

Excellent solution. My scenario was clicking on the Label should open a Modal Pop-Up after performing few operations in Code-Behind. The page was really should the post back even though it was in UpdatePanel. Your blog gave me the Answer!!!

function OpenModal(btnHDNCI)

{

var btnHDN = document.getElementById(btnHDNCI);

doPostBackAsync(btnHDNCI,'OnClick');

// __doPostBack("'"+btnHDNCI+"'",'OnClick'); //--- This actually did full postback

}

function doPostBackAsync( eventName, eventArgs )

{

var prm = Sys.WebForms.PageRequestManager.getInstance();

if( !Array.contains( prm._asyncPostBackControlIDs, eventName) )

{

prm._asyncPostBackControlIDs.push(eventName);

}

if( !Array.contains( prm._asyncPostBackControlClientIDs, eventName) )

{

prm._asyncPostBackControlClientIDs.push(eventName);

}

__doPostBack( eventName, eventArgs );

}

Hi Coriscow,

I'm not exactly sure what you're doing but the exception occurs because te parameters that are passed to the function do not match the conditions. But you probably figured that out yourself :-)

It think you can easily solve this at the serverside aswel. If you mark CallBackHome as a trigger for the updatepanel you can call your custom control in CallBackHome's eventhandler.

Hi Martinjn!!

I tried your solution, and it almost works for me. I have an UpdatePanel with a custom control inside of it (ID=romulo : IPostBackEventHandler) and a button (ID=CallBackHome) outside. My intention is to do an async postback when CallBackHome is clicked. This postback has to be received by romulo. However, it crashes in the following function from the Microsoft Ajax lib, more specifically at 'if (e) throw e;'. If I skip that line it works perfectly. Any clue you could give me?? Thanks in advance!

<code>

Sys.WebForms.BeginRequestEventArgs = function Sys$WebForms$BeginRequestEventArgs(request, postBackElement) {

/// <param name="request" type="Sys.Net.WebRequest"></param>

/// <param name="postBackElement" domElement="true"></param>

var e = Function._validateParams(arguments, [

{name: "request", type: Sys.Net.WebRequest},

{name: "postBackElement", domElement: true}

]);

if (e) throw e;

Sys.WebForms.BeginRequestEventArgs.initializeBase(this);

this._request = request;

this._postBackElement = postBackElement;

}

</code>
