    Gridpanel, lastSelectedRow and currentSelectedRow

    I have a question about the getLastSelected method. I am unable to get the last selected row with this method.

    Please see the following code. I am keep getting the current selected row index as seen in the pop up message.

    It would be great to get the last selection and the current selection after an edit event occur. With these information, I can call the update method if a new selection has been made (I.E: users click on different row after edit)

    Thank you for your time and insight!!!

    Hi @oooh,

    It selects the record before editing, it is why the getLastSelected method returns currently edited record.

    A RowSelectionModel's Deselect is fired before editing. You can use it.
    <ext:RowSelectionModel runat="server">
    <Listeners>
        <Deselect Handler="/* use it */" />
    </Listeners>
</ext:RowSelectionModel>
