    [CLOSED] Storing the unselected filter in the grid panel in my database....

    Hi

    In my situation i have a grid panel with header context menus column check box i.e with the column select and deselect options. In default all the column are shown. And if the user wants he/she can uncheck the column checkbox so that the column is removed(hides)..

    Now in my situation i want to store the unselected checkbox in my database and again show when the user login next time with the unselected has he/she as logout.. is there any possibility to achieve it.

    Can u demonstrate it with an example... It would be really helpful

    thank you..

    Regards,

    Hi,

    you should handle HiddenChange event of column model. I wrote simple example which using static collection as simple store.
