Problem with partial post back & master page

Hi,

I have ASP.NET user control that implements ICallbackEventHandler. Partial
postback works perfectly when I put control on a regular webform.
But when I put it on page that has master page control doesn't work.

I'm getting following error :"The target <name> for the callback could not
be found or did not implement ICallbackEventHandler."

It's error like when control didn't implement ICallbackEventHandler, but
this one did. The only difference is when I put it on page that has master
page things stop to work.

Any ideas how to solve this problem is very appriciated. I'm stuck with this
for days and going crazy...

Thank you,
s

I had the same problem but found the solution..

The issue I had was that in the WebForm_DoCallback in the first parameter
position I was using the Control.ClientID and this is not correct as it uses
the underscore as a seperator. When I use the Control.UniqueID then
everything is fine as it uses the colons.
I noticed this when I found that the
Page.ClientScript.GetCallbackEventReference call returns a string and in the
string I they use of the Control.UniqueID.

This is the code I ended up with just to show the overloads I used.

WebForm_DoCallback('" & Me.UniqueID & "',eventName,
ClientSideAjaxCallback,srcID);

Page.ClientScript.GetCallbackEventReference(Me, "",
"ClientSideAjaxCallback", "", False)
