Event handler for a client side OWC component

[nickless]

Hello Alvin,

There is an asp page that embeds the OWC object in the client and
defines event handlers like this:

<script language="javascript" for="ChartSpace"
event="CommandBeforeExecute">
<script language="javascript" for="ChartSpace"
event="BeforeContextMenu">
<script language="javascript" for="ChartSpace" event="Click">

how do i do the same in an aspx page (asp.net 2.0).
I have embedded the object in the aspx page (with clsid) properly, but
i do not know how to declare event handlers for it. the usual set of
EvenHandlers do not work for this object (onclick, onkeydown ...etc)
Also CommandBeforeExecute, BeforeContextMenu defined are not a part of
the intelliSense drop down.
Could you please suggest a method to do it.

Thanks in advance

OWC is a client side object, it does not run on the server. Event handlers
in an aspx page execute on the server. What you want to do is simply not
possible because a client object cannot fire server side code. You will need
a bridge between the client and the server to accomplish that.

ok, that is understood. Thanks.
but i want to run some Javascript on the client when the user clicks
the Chartspace object embedded in the page.

Q1: I have ave embedded the object like this:
<object id="ChartSpace" classid="clsid:0002E55D-0000-0000-
C000-000000000046" onclick="showMessage();"></object>
but the call to showMessage doesnt fire ! am i missing something here?
(I have tried other events available ..like onKeyDown etc even they
dont fire)

Q2: Eventually if i get to the events to fire how do i declare custom
events such as CommandBeforeExecute or BeforeContextMenu used in asp
page
in the aspx page.

Thanks again

Hello Alvin,

I request you to take a look at the post and suggest a direction, I
have hit a dead end on this one.
will be very helpful to me.

Hoping you would reply!
Thanks

You do the same thing in aspx as you do in asp

intellisense will complain at compile time because the schema will not
recognize the for keyword. But it will work at run time.
