Postback and RegisterForEventValidataion

[SECSteve]

I am working with a radio button group. Depending on the seleciton panels
and controls will show/hide. I keep getting an Invalid Postback or Callback
argument. I have tried registering the values that I am using in render()
with ClientScript.RegisterForEventValidation but it is not working.

The buttong group only has 2 choices. At load choice #1 is selected. I can
select #2 and the proper events happen. However, if I go back to choice #1
I get the error. I have not found a satisfactory solution on the web.

Any ideas?

Here's a little more info that might help. All of these controls are in an
update panel. 1 of the controls that appears during the SelectedIndexChaned
event of the radio button is a drop down that is populated from a database.
If I comment out the code that populates the drop down everything works ok,
I don;t get the error.

This makes me thingk that I have to use the render()
ClientScript.RegisterForEventValidation for every value in that drop down.

How do I do that for a dynamically populated control???

Is there a better way, somethging that I am missing? After all, I am pretty
new to this.
Thanks.

Hello,

DropDownList should register it's values for event validation already. Is it
sure that you aren't databinding it on every request?

Could you provide a relevant snippet of your code (feel free to email me
directly), so I can take a look at it.
