How to create event handler for ASP control like Tridion control?

I have an aspx page PopupReference. I am having Tridion control button and few asp controls too, like asp:ddSelectOption (Dropdown).

So in Popupreference.js as we are creating event handler for Tridion button I am trying to create the same for my asp controls as below:

This is Tridion button:

c.InsertButton = $controls.getControl($("#InsertButton"), 
                                      "Tridion.Controls.Button");

This is my dropdown:

c.ddSelectOption = $("#ddSelectOption");

Event handler for tridion button:

$evt.addEventHandler(c.InsertButton, "click", this.getDelegate(this._execute));

Event handler for my dropdown:

$evt.addEventHandler(c.ddSelectOption, "onselectedindexchanged",
                     this.getDelegate(this._ondropdownitemchanged));
console.log('eventhandler created');

I am calling the function :

RTFExtensions.Popups.PopupReference.prototype._ondropdownitemchanged = 
                      function PopupReference$_ondropdownitemchanged(event) {
  Console.log('Initializing inside dropdown...');
};

But I am not able to see the last log anywhere, I think its not getting inside the function ondropdownitemchanged(event). Does anyone have any clue how I can make this happen?

I suspect your onselectedindexchanged event needs to be a change?

I've implemented something similar using a drop down, here are the pieces from my code. I hope this helps you to find your solution:

1) In the html / aspx page:

<select id="systemDD"></select><label for="systemDD">Select a system</label>

2) In your JavaScript:

var p = this.properties;
var c = p.controls;

// the the drop down items
c.SystemDropDown = $("#systemDD");

Adding the event handler:

$evt.addEventHandler(c.SystemDropDown, "change",
                     this.getDelegate(this._systemDropDownChanged));

The method:

EditorName.prototype._systemDropDownChanged = 
function EditorName$Extensions$EditorName$_systemDropDownChanged() {
    var p = this.properties;
    var c = p.controls;
    // get the selected system value
    var selectedSystem = $j(c.SystemDropDown).val(); 

};

I'd tackle it in the following ways:

  1. When you get the dropdown element, check that you have it as an object
  2. Try changing onselectedindexchanged to just 'change'
  3. A strong alcoholic drink :)

Good luck
