[solved]automatic expand combobox in grid

[Spirit]

I know this has been discussed a few times but i found no contribution where it works.

I tried 2 approaches:

First i tried to add an listener to my grid:

		listeners: { 
		   	celldblclick: function(o, row, cell, e) {
		      	o.getColumnModel().getCellEditor( cell, row).field.expand();
	     },

The editor is a Ext.form.ComboBox, so i thought this should work but it does not.

My second approach:
I added an listener to my editor (Ext.form.ComboBox), so i could expand my combobox when it gets focus. Again there is no problem of catching the desired event but if i try to expand
the combobox i get the following error:
>>this.list has no properties

I dunno why i get this error. The store of my combobox is autoloaded, so i m pretty sure the list should exist. I tried playin around with mode, lazyRender and loaded the store explicitly but noting helps.

[CODE]
var storestatusrg = new Ext.data.JsonStore({
url: 'rgcbs.php',
baseParams:{typ:'status',langid:1},
root: 'items',
fields: ['id', 'name'],
autoLoad:true
})


cbtyprg = new Ext.form.ComboBox({
storetoretyprg,
triggerAction: 'all',
emptyText:'Bitte w

...i know everyone is reading the licensing threat so nobody has time... but ... can someone point me in the right direction.

bump!

Configure your combobox with a focus listener which calls onTriggerClick

[Spirit]

Thats what i did in the second example above. And i get an error:
this.list has no properties

See above :/

You need to set scope.

What do you think "this" is going to be inside that function?

[Spirit]

Hmmm... has nothing to do with scope this time... or i am i totally wrong ?

[CODE]
cbtyprg = new Ext.form.ComboBox({
storetoretyprg,
triggerAction: 'all',
emptyText:'Bitte w

You have to use lazyRender:false in this case otherwise it only renders the list on focus by adding its own 'focus' listener.

By using the listeners config, you get the first focus listener in, and so find it with no list rendered!

storetoretyprg,
triggerAction: 'all',
emptyText:'Bitte w

@Animal: Thx, but i couldnt get it work with lazyRender:false, still needed a delay...

Thx Cronos ... just as i found a solution...

				listeners: { 
 				    focus :{scope:this, fn:function(field) {
						      field.onTriggerClick();
 				    	},buffer:200} 	
				   }

... i saw your code and it also works like a charm.
Thx a lot you 2
