Canceled event is not reverting RadButton to initial value

[Brett]

Setting the cancel property (to true) of the telerik eventArgument (e) accompanying the RadButton Client OnValueChanging event is no longer setting the value back to the oldValue or initialValue.

I put up a StackOverflow Question in this regard.

actually.. it does revert the value back if I blur / raise the onchange event of the radTextbox a second time. I have debugged through this, and it is setting e._cancel to true each time.

I have also commented out the xhr.send line, forcing it to return my error response: `{ "isValid" : false, "isOverrideable" : false, "StatusCode" : 500 }`. the issue persists.

The issue seems to be with sender.get_editValue in the sender._setValue method.. when is the edit value assigned/determined.. is it not before the OnValueChange event is raised?

First, can a moderator move this thread to the Appropriate RadTextbox forum, I just noticed that I apparently put this in the RadButton forum..


I'm still not sure what the root of the issue is, but I can see how to resolve/workaround this behavior.

sender.get_displayValue, sender.get_editValue, sender._text don't reflect the value in e.get_newValue() ... explicitly calling sender._setHiddenValue(e.get_newValue) seems to resolve canceling of the event properly.. 


The canceled event handler seems to call sender._SetValue(sender._initialValueAsText), (I kind of expected it to use e.get_oldValue, but I suppose keeping the initial value with the control instance reduces/prevents timing and sync issues/considerations).. Since _SetValue essentially call sender._setHiddenValue.. I would expect, at the very least, that sender._value should reflect to the value of e.get_newValue();
