I want to do some server side process on cellselection changed in webdatagrid.I was able to capture the event and get the changed values but the problem is it fires twice.once i enter the cell by clicking it fires the event, and after changing the values and when i tab out it fires the event.I want to stop it firing the event when i click and enter the cell.My behaviour setting are as below.

<Behaviors>
                       <ig:Activation  Enabled="false">
                            <AutoPostBackFlags ActiveCellChanged ="false" />
                       </ig:Activation>
