RadNumericTextbox OnValueChanged Client-Event fires twice

[Tejas]

Hi Team,

I have RadNumericTextBox on my page with Client-Event OnValueChanged.
I've defined a client-side function to handle the event. Whenever I change value, It fires the event correctly but when try to set the value to textbox using sender.set_value() method it sets the value and fires the event again. Is this the expected behavior for RadNumericTextBox ?
Please note that I display a confirmation message to user which is being displayed twice now, I know we can trick the javascript to display message only once but I dont understand why this event fires twice.
Any clue will be appreciated.

Thanks

Hello Tejas,

set_value changes the value of the control, so the ValueChanged event should be fired. By design this is the correct behaviour.

You may trick it using code like:

var set_valueCalled = false;

function HandleValueChanged(sender, args)
{
    if (!set_valueCalled)
    {
        set_valueCalled = true;
        alert("some alert");
        sender.set_value( "some_new_value");
        set_valueCalled = false;
    }
}
