How can I cancel OnSelectedIndexChanged ?

[Shawn]

Hi.
I have a DataGrid with a DropDownList, like this:
<aspropDownList id="ddlStatusCode" OnSelectedIndexChanged="SetDirty"
runat="server"></aspropDownList>
If the user selects a new value I set a flag on the row in the SetDirty
method so that I know the row has been changed. My problem is that now I
have to change the value of the DropDownList myself using a javascript, but
I don't want the SetDirty method to set a flag on the row. Can I use a
javascript to somehow cancel the OnSelectedIndexChanged event?

Thanks,
Shawn

You should then pass another post variable letting your server code know
it was the javascript that changed the value, not the user. Check out Page.RegisterHiddenField
to create a new hidden field for the flag.

Thanks Allen,
I've already solved it by using session to set a new flag, but I was hoping
there was a way to cancel the event without having to set a new flag.

Nope, there's not really since all the server knows is that the posted value
is now different than the previous value.
