Probably, but we'll need to see a bit of the relevant code.  Start with
the DataGrid declaration mxml and the change handler function.

Subject: [flexcoders] 2 Datagrid issue

 

Hi,

I have 2 DataGrids working with a custom renderer and all that jazz 
but 2 seperate ArrayCollections as data provider. On select of an 
item in one grid I set the data['selected'] property accordingly and 
call an itemUpdated in the ArrayCollection. Can anyone think why a 
selection in one grid is also selecting an item in the second grid?

Hi Tracy,

// MAIN MXML
ac = new ArrayCollection(dp); //dp = array of objects
bc = new ArrayCollection(dp);

private function onChange( e:ListEvent ):void
{
// Multiple checkboxes able to be selected so
// deselect all then reselect single checkbox.
for ( var i:int = 0; i  ac.length; i ++ )
{
ac.getItemAt(i).selected = false;
bc.getItemAt(i).selected = false;
}

	if( e.itemRenderer.data.column == e.columnIndex   
e.itemRenderer.data.row == e.rowIndex ) e.itemRenderer.data.selected =  
true;


ac.itemUpdated( e.itemRenderer.data );
bc.itemUpdated( e.itemRenderer.data );

}

// CUSTOM RENDERER
override protected function clickHandler(event:MouseEvent):void
{
super.clickHandler(event);

this.visible = false;

data.selected= selected;
data.row = listData.rowIndex;
data.column  = listData.columnIndex;
}

As Tim guessed in his post, your two Acs share the same source, so are
essentially one dataProvider.

 

Use concat() to make a copy of dp before you create bc.
