Hello Ram,

Your code seems fine. Which is the version of the grid that you are using?  How long time it takes to iterate through the rows ?  Is there any difference about the performance with different browsers?

Thanks.

Hello Rado,

Were you able to look into the issue? I have copied the JavaScript code for your reference.

Thanks!

Here is the javascript code -

        var _IsEngagementItem = false;

        function selectDeselectAllDelete() {

            var grid = igtbl_getGridById('grdResult');

            _SkipAfterCellUpdate = true;

            for (i = 0; i < grid.Rows.length; ++i) {

Hey Ram,

Can you paste your javascript code used to iterate through the rows please?

Thanks.

I have around 100 rows in the grid. Checking all the items for the first time takes a lot of time, subsequent checks/unchecks are little faster.

Can something be done for this?
