[Solved] $addHandler

[Michael Tissington]

I'm trying to use $addHandler to hook up some client side events but my event handlers are not getting called ...

Can you provide an example of using the $addHandler AJAX method to do this please.

Hi Michael Tissington,

What event do you want to add? If it is, for an example, SelectedIndexChanged, you can do it, like:

combo.add_selectedIndexChanged("NameOfTheEventHandler");

Hope this helps.

Hmm, thanks ... its is OnClientSelectedIndexChanged ... I have tried add_selectedIndexChanged and the code executes but my code does not catch the event ...

If I do 

rcb = $find("<%= SearchPanel.FindItemByValue("ItemWhat").FindControl("What").ClientID%>");

rcb.add_selectedIndexChanged("What_SelectedIndexChanged");

I get Microsoft JScript runtime error: Sys.ArgumentTypeException: Object of type 'String' cannot be converted to type 'Function'.
Parameter name: handler

And if I do similar without the quotes

rcb.add_selectedIndexChanged(What_SelectedIndexChanged);

the code executes but I do not catch the event.
