I know textchanged event fires only after the TB loses focus. But i want myfunc() (present in code behind) to fire immediately after text changes in the textbox. I have already tried textchanged event, webmethod etc but nothing really worked. Can Ajax do it? or any other ways?

Remember myfunc() has some ado queries so that some values in a panel changes after each change in textbox.

Thanks

Make sure that CausesValidation is set to false.

It is already set to false.

You need to use javascript and onkeyup.

Solution 1

JavaScript

$('#textMessage').keyup(function(event) {
  if (event.keyCode == 13) {
    var message =  $('#textMessage').val();
    alert(message);
  } else {
    return true;
  }
}); //endTextMessage keyup

You may use in this way

I need to execute some SQL queries within that function and assign the output values to some controls. All that should happen when text changes in the textbox.
Now Question is can i use SQL queries in a Javascript function? If yes then how?
