I'm trying to do a dynamic search with the textbox...but it's really tanking with

  1. backspace, always a letter behind
  2. paste: so if I type 'ste' into the box, copy and paste it, the value is stev (ctrl-v for paste)

I need live text to be passed into the service

This is what I'm doing, but again, epic fail :)
$('#directorywidgetClientState').attr('value', sender.get_textBoxValue() + args.get_keyCharacter());

Hi Steve,

I suppose you are using the keypress/keydown events in your scenario, but as they do not work consistently in all browsers (due to browser inconsistencies), you will have problems with retrieving the correct textbox value.

That's why I suggest you to leave the key events alone and retrieve the textbox value constantly once the control receives focus. You will need the setTimeout and setInterval Javascript methods.

Best wishes,

I'm sorry, how do you mean :)

...I need to know what's in that RadTextBox as I type into it.

So then handle OnFocus to start a timer, and stop the timer on ValueChanged?

KeyPress then I take it is to just prevent certain keys from being used eh

Hi Steve,

>> "and stop the timer on ValueChanged"

I suppose OnBlur will be better in this case - ValueChanged is fired also when programmatic value change takes place and in this case you will have no timer to stop, because the control has no focus.

Here's the code if someone else needs it...timer set at 1 second

//Global Vars
var directoryTimerID = 0;
var directorySearchBox = null;
 
//Start the timer when it gets focus
function onDirectorySearchFocus(sender, args) {
    directoryTimerID = setInterval("directorySearchTimer()", 1000);
    directorySearchBox = sender;
}
 
//Clear the timer when it loses Focus
function onDirectorySearchBlur(sender, args) {
    clearInterval(directoryTimerID);
    directorySearchBox = null;
}
 
//Timer callback function
function directorySearchTimer() {
    setDirectoryClientState(directorySearchBox.get_value());
}
