removing a row / redrawing table doesn't update row count

Vexiphne

How can I get the row count to update when you delete rows from a datatable ?

Did you ever get a response to this? It is happening for me as well. I'm using 1.7 and when I do fnDeleteRow the row is removed from the table but the count stays the same.

Same issue here.

I'd guess you are using server-side processing. Is that correct? If so, then you should note that fnDeleteRow is suitable for client-side processing only - if you are using server-side processing (i.e. "bServerSide": true), then to add data, you must add it to the data source, i.e. the server-side, through an Ajax call.

If you aren't using server-side processing, please link me to a test page so I can see the issue.

I'm having a similar issue - I have a few drop downs that filter the data in my table on the client side based on a css class name applied to each row on the server side. The logic with this filtering can only be done on the server side, so I applied css class names to match the item in the drop down with the class. I'm caching the tr's with javascript since i have 2000+ rows, then showing/hiding rows in the drop down's .change event with display: none using an array.

Here's an example (#issueBody is the table's );
[code]
// Since ddlPriority is data base driven, dynamically build class selectors
var $priority0 = $('tr', '#issueBody');
var priorities = { priority0: $priority0 };
$("#ddlPriority > option").each(function () {
if ($(this).attr('class') != 'priority0') {
var style = $(this).attr('class');
var $tr = $('tr.' + style, '#issueBody');
priorities[style] = $tr;
}
});
$('#ddlPriority').change(function (e) {
e.preventDefault();
var select = e.target;
var option = select.options[select.selectedIndex];
var filter = $(option).attr('class');
$priority0.addClass('priorityFilter');
priorities[filter].removeClass('priorityFilter');
});
[/code]

The priorityFilter class is simply display: none. The options are priority0, priority1... priority[n] based on a database table's values. There's another one that does the same thing, so the filtering of both are applied to the table.

How can I get the table row count to update when I perform this filtering? Is there a better way to do this to be compatible with DataTables?

Thanks!
