OnBlur

The OnBlur event handler is raised when a textbox extended via the RadInputManager loses focus.

The signature of the event handler is unified and is the same as in the other client side event handlers available for the control. It receives two arguments - the sender which raised the event, and another argument, which gives access to additional client side methods.

Below is a small code snippet, which demonstrates how to get the value which the user entered in a textbox, when the focus is lost:

function OnBlur(sender, eventArgs)
{
    alert(eventArgs.get_targetInput().get_value());
}
