dropdownlist onchange squiggly

[Guest]

hey all,

<aspropDownList id="DropDownList1" runat="server" onchange="Test();">

can someone please tell me why the onchange has a squiggly and if there is a
better way to access the client-side change event for the drop-down list?

The message is saying it's not a valid attribute of the drop down list
element but yet it still works for me?

thanks,
rodchar

Yes, you catch this message, but looked to the rendered code too?
The point is:
All attributes where not available in the control, throw such a message.
But ASP.NET do render all that attributes AS-IS to the Html Code.
In this point, this is not a fail in any case, but rather a possible
improvement for a future version of Visual Studio

Another way to add "custom" attributes to your control is wrote them in your
codebeside like:

this.dropTest.Attributes.Add("onchange", "foo(this.value);");
what's the best way to find all the possible client-side events for any
control?
