[CLOSED] Custom Search Combobox setValue not Working in Ext 2.2
i have created custom search combobox
in combobox's render listener i am setting the combobx value by
setValue and setRawValue
it is working but when i press down arrow key the value which i have set
is not selected (it is working properly in version 1.1)
as per documented for combobox
setvalue method fires events -
change
dirtychange
validitychange
how to prevent for firing the change event?
it is not working by using suspendEvents() and resumeEvents() in ie
how to achieve it?
In Ext.net 1.1
