Flex datagrid column disable and enable

Question

In my flex application im using a datagrid with following columns

<mx:DataGrid x="10" y="265" width="1205" dataProvider="{vendors}"  editable="true" lockedColumnCount="4"   horizontalScrollPolicy="on">
                        <mx:DataGridColumn headerText="Select" editable="false" textAlign="center" >
                        <mx:itemRenderer >
                            <mx:Component>

                                <mx:CheckBox click="data.select = !data.select"  change="outerDocument.addDetail(data)"  selected="{data.select}" > 
                                </mx:CheckBox>
                            </mx:Component>
                        </mx:itemRenderer>
                    </mx:DataGridColumn>

                    <mx:DataGridColumn headerText="One" dataField="one" color="black" editable="false" width="125" />
                    <mx:DataGridColumn headerText="Two" dataField="two" color="black" editable="false" width="125"/>
                    <mx:DataGridColumn headerText="Three" dataField="three" color="black" editable="false"/>
                    </mx:DataGird>

now i want to disable the checkbox column on fetching data..after datas are populated in datagrid if user selects any of the field in datagrid for editing..the checkbox for that selected row should be enabled...other rows checkbox should be disabled..

I hope this information is enough for this requirement

I dint understand completely your problem but trying to answer it.

<mx:DataGrid x="10" y="265" width="1205" dataProvider="{vendors}"  editable="true" lockedColumnCount="4"   horizontalScrollPolicy="on" id="dgGrid">
                    <mx:DataGridColumn headerText="Select" editable="false" textAlign="center" >
                    <mx:itemRenderer >
                        <mx:Component>

                            <mx:CheckBox click="data.select = !data.select"  change="outerDocument.addDetail(data)"  selected="{data.select}"
enabled="{outerDocument.dgGrid.selectedIndex==outerDocument.vendors.getItemIndex(data)}> 
                            </mx:CheckBox>
                        </mx:Component>
                    </mx:itemRenderer>
                </mx:DataGridColumn>

                <mx:DataGridColumn headerText="One" dataField="one" color="black" editable="false" width="125" />
                <mx:DataGridColumn headerText="Two" dataField="two" color="black" editable="false" width="125"/>
                <mx:DataGridColumn headerText="Three" dataField="three" color="black" editable="false"/>
                </mx:DataGird>

This will work If your dataprovider for grid is an arrayCollection which is declared as public..
