    [CLOSED] Row Selection in grid panel

    Hi,
    I am using paging concept in grid panel, this method "GrdPnl1.getRowsValues(true)" is worked fine in previous version to get the selected rows, after i updated Svn. this method returns empty value. then i used "GrdPnl1.getRowsValues(true, false, false, true)" to get the selected row, its working but it is very slow, it takes 10 to 15 seconds to select a row. in my grid there is 20 pages and page size is 20

    Hi,

    Here is my test case, I don't see any problems. Can you modify this example to reproduce the problems which you described?

    If you don't need restore selection after grid's pages navigation and don't need 'Get Selection From All Pages' then set SelectionMemory="Disabled" for GridPanel
