I am creating an Ajax Client Control in ASP.Net. By inheriting from IScriptControl and then adding the relavant javascript class (which would inherit from a javascript control). I have found a memory leak in the following code:
Type.registerNamespace("mynamespace");
myClass = function (element) {
myClass.initializeBase(this, [element]);
}
myClass.prototype = {
initialize: function () {
myClass.callBaseMethod(this, 'initialize');
var me = this;
$(document).ready(function () {
me._initializeControl();
me._hookupEvents();
});
},
dispose: function () {
//Add custom dispose actions here
myClass.callBaseMethod(this, 'dispose');
},
//...other code ...
_hookupEvents: function () {
var me = this;
var e = this.get_element();
$("#viewRates", e).click(function () {
me.openDialog();
});
},
//...other code...
myClass.registerClass('myClass', Sys.UI.Control);
if (typeof (Sys) !== 'undefined') Sys.Application.notifyScriptLoaded();
_hoookupEvents is a function in my javascript file. The leak is related ot the line me.openDialog. If I remove this line, there is no leak. However, I need this line to be able to call a function from the class (I cannot just use 'this' in the function because it would refer to the button). Is there a better way to do this? Or maybe I just need to call some methods in the dispose function to clean such things?
