View Full Version : Combo Box on Form Custom Renderer

26 Mar 2014, 10:35 AM
Is there a Renderer function (like I have for columns in grids) for a combo box on a panel? I want to customize the display field depending on other columns in the grid?

It's not quite the same, but you do have access to the tpl and displayTpl properties to control the look of the combo box display.

Customized combobox

// Template for the dropdown menu.
// Note the use of "x-boundlist-item" class,
// this is required to make the items selectable.
tpl: Ext.create('Ext.XTemplate',
'<tpl for=".">',
'<div class="x-boundlist-item">{abbr} - {name}</div>',
// template for the content inside text field
displayTpl: Ext.create('Ext.XTemplate',
'<tpl for=".">',
'{abbr} - {name}',

I did see that in the doc, however, I am using SA 3 and I don't see a property for tbl or displayTplAlso, I need to do some conditional output depending on the value of another field:i.e if (record.data.parentID >0) return '' + record.data.description + '

Not sure why SA3 doesn't expose these. If nothing else, I think you could put them in a Process Config function.

The XTemplate is capable of doing conditional logic. It has a basic if test built in as well as the potential of adding template member functions to execute arbitrary JavaScript code. I've used this before to conditionally style certain entries in a ComboBox.

THANKS! That gave me a good place to look at. All seems good now (crossing fingers and toes!)bruce
