[flexcoders] Re: Number column in DataGrid

2007-06-15 Thread headjoog 

The data provider for the grid is masters an ArrayCollection.  The
form uses master which is an Object.  I had to include the
Number(txtMasterRate.text) in the Binding or I get the type coercion
error when trying to save back to the database.  It almost works - when
I make an entry in the form, the grid is updated.  But trying to enter a
decimal causes weird behavior - it backspaces and clears the previous
entry. (No - it's not my keyboard)   Is there another approach to use?



The datagrid looks like this:

mx:DataGrid id=dgMasterStatus editable=true
dataProvider={masters} width=457 change=mastersChange()
valueCommit=mastersChange()

mx:columns

mx:DataGridColumn headerText=Rate width=120 dataField=masterRate


/mx:DataGridColumn

/mx:columns

/mx:DataGrid

==

Then the form looks like this:

mx:Form width=264 

mx:FormItem label=Rate

mx:TextInput id=txtMasterRate text={master.groupRate} 



/mx:TextInput

/mx:FormItem



And the Binding looks like this:

mx:Binding source=Number(txtMasterRate.text)
destination=revmaxmaster.masterRate /

Are
 you set up that way? What does the binding look like?

 Nope - same results. I think the mx:Binding is causing the weird
 behavior. If I take it out, I can type numbers with decimals in the
 mx:TextInput item. But with it in there, it won't allow any
 decimals.
