    Default Unanswered: Checkbox slection model does not get checked when locking grid column is used

    Unanswered: Checkbox slection model does not get checked when locking grid column is used


    Hi
    I have implemented a grid which has Check box selection model and made the check box column is locked but when i click the checkbox to select all items its not selected so iam manually looping through the store data and checking each item but the performance is low when the records exceed 100 in the grid.Can anyone suggest the best way to do to increase the performance.


    Thanks in advance
