If I'm not wrong that is a bug in 2.0.1 (it was not in 2.0)...
2007/3/9, Sergey Kovalyov <[EMAIL PROTECTED]>:
Hi All! I have a DataGrid and its dataProvider property is binded to ArrayCollection. When I first hide one column via firstColumn.visible = false and then binding executes, that column appears again. How to prevent this unnecessary appearance? Click "Hide Middle Name" and then "Populate" in this example: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; creationComplete="onCreationComplete()" > <mx:Script> <![CDATA[ *import* mx.collections.ArrayCollection; [ *Bindable*] *protected* *var* users : ArrayCollection; *protected* *function* onCreationComplete() : * void* { users = *new* ArrayCollection(); users.addItem({firstName : *"George"*, middleName : *"W"* , lastName : *"Bush"*}); } *protected* *function* onPopulateButtonClick() : * void* { users = *new* ArrayCollection(); users.addItem({firstName : *"Victor"*, middleName : *"A"* , lastName : *"Yuschenko"*}); } ]]> </mx:Script> <mx:DataGrid dataProvider="{users} "> <mx:columns> <mx:DataGridColumn id="firstNameDataGridColumn" dataField=" firstName" headerText="First Name" /> <mx:DataGridColumn id="middleNameDataGridColumn" dataField=" middleName" headerText="Middle Name" /> <mx:DataGridColumn id="lastNameDataGridColumn*" * dataField="lastName" headerText="Last Name" /> </mx:columns> </mx:DataGrid> <mx:Button label="Hide Middle Name*"* click=" middleNameDataGridColumn.visible = *false*" /> <mx:Button label="Populate" click="onPopulateButtonClick()" /> </mx:Application> Sergey.
