Notes On Siebel

Dynamically Show/hide a Control

July 30th, 2007

The browser script Control method ‘SetProperty’ is fairly limited: it only works at all with CheckBox, ComboBox, TextBox and TextAreas, and even with these controls I’ve found behaviour to be flaky. In my experience it’s more reliable to grab a handle to the control and access the DOM properties directly.

For instance, to conditionally show or hide a control using browser script, the code looks like this:

var ctrl = thisApplet.FindActiveXControl("My Control");

if( ctrl != null )

{

  if( myFlag )

    ctrl.style.visibility="visible";// show control

  else

     ctrl.style.visibility="hidden";// hide control

}

This approach can also be used to set other display properties - like the font and colors - but you have to be a bit more careful with interactive properties: the standard HTML property disabled does not work the same as Siebel’s Enabled control property, for instance.

The best reference I’ve found to the complete set of DOM properties is on MSDN, with the advantage that everything here should be available to Siebel’s IE-only environment.
