After upgrading to RadControls for ASP.NET ( not ASP.NET AJAX ) my client-side validation does not perform properly. The code below puts the function into an infinite loop.
function ValidateLongitude(sender, args)
{
var newValue = String(args.NewValue);
if( newValue.charAt(0) != '-' )
{
newValue = '-' + newValue;
sender.SetValue(newValue);
}
if( newValue.length >= 4 && newValue.indexOf('.') < 0 )
{
if( newValue.substring(0,4) < -520 )
{
newValue = newValue.substring(0,3) + '.' + newValue.substring(3);
}else{
newValue = newValue.substring(0,4) + '.' + newValue.substring(4);
}
sender.SetValue(newValue);
}
if( newValue != '' && (newValue > -52 || newValue < -142 ))
{
sender.SetValue('');
}
}
Given the code below does not cause an infinite loop, can you explain why Telerik is calling the OnValueChanged every time we try to set the text box to a new value?
<html>
<head>
<script>
function BlurIt()
{
var x = document.getElementById("txtID");
x.value = "new value";
}
</script>
</head>
<body>
<form>
<input type="text" id="txtID" onblur="BlurIt();">
</form>
</body>
</html>
And upgrading to Asp.net AJAX is not option.
function ValidateLongitude(sender, args)
{
var newValue = String(args.NewValue);
if( newValue.charAt(0) != '-' )
{
newValue = '-' + newValue;
sender.SetValue(newValue);
}
if( newValue.length >= 4 && newValue.indexOf('.') < 0 )
{
if( newValue.substring(0,4) < -520 )
{
newValue = newValue.substring(0,3) + '.' + newValue.substring(3);
}else{
newValue = newValue.substring(0,4) + '.' + newValue.substring(4);
}
sender.SetValue(newValue);
}
if( newValue != '' && (newValue > -52 || newValue < -142 ))
{
sender.SetValue('');
}

I have this same problem in 2008 Q2 SP2...
In my case I cannot use onblur because I am firing a server load based on the value and I don't want it to fire evertime I exit the textbox if the value doesn't change.
See the description and code here:
http://www.telerik.com/community/forums/thread/b311D-bdagge.aspx
Please advise on how to suppress this behavior since it is NON-Standard javascript behavior, an Html Input control does not fire onchaged when setting the value from javascript, only when setting the value from the keyboard.

You will find most of Telerik's javascript implementation is 'non-standard'.
