WebImageButton Utility Functions

The client-side object model for the WebImageButton™ control is accessed in HTML using the JavaScript Client Side Object Model (CSOM). The server object model can be accessed in the ASP.NET code-behind class or inline code in the ASPX file.

Using JavaScript, you can:

  • process events that occur on WebImageButton controls

  • obtain references to JavaScript Objects related to WebImageButton controls located on a page at any time. This allows the developer to get and modify values of their properties and behavior

  • obtain references to the html elements that are used to render WebImageButton objects. This also allows the developer to get and modify values of their properties

Accessing the WebImageButton Client-Side Object (three ways):

  1. Access the WebImageButton client-side object while processing the ClientSideEvents of WebImageButton (the first parameter in handler function contains reference to the WebImageButton).

function myMouseDownHandler(Button, Event)
{
	window.status = "Mouse down:" + Button.getText() +
	  " button with id:" + Button.getClientID();
}

  1. Access the WebImageButton client-side object within the page using the global ig_getWebControlById utility function.

var button = ig_getWebControlById("WebImageButton1");
window.status = "WebImageButton1 has text: " + button.getText;

  1. Access the WebImageButton client-side object from a reference to a child HTML element that belongs to WebImageButton using the global igbut_fromElem utility function.

// childTD - reference to one of
// TD/IMG/SPAN/INPUT-html-element used by WebImageButton
var button = igbut_fromElem(childTD);
if(button != null)
	window.status = "childTD belongs to: " + button.getClientID();
