Is there a way to test if jqGrid has data or not?

Question

I'm trying to enable and disable custom buttons on a jqgrid, but would enable that button only if the grid is empty and then disable when its not.

Is there a way to test of the grid has data or not?

Thanks.

Answer 1

You can test to see how many records are in the grid. If there are no rows then the grid is empty:

jQuery('#grid').jqGrid('getGridParam', 'reccount');

See the documentation for reccount:

Readonly property. Determines the exactly number of rows in the grid.

Also, since the default value is 0 you need to make sure you call this function after data has loaded, such as in the loadComplete event.

Answer 2

From the docs:

reccount integer Readonly property.

Determines the exactly number of rows in the grid. Do not mix this with records parameter. Instead that in most cases they are equal there is a case where this is not true. By example you define rowNum parameter 15, but you return from server records parameter = 20, then the records parameter will be 20, the reccount parameter will be 15, and in the grid you will have 15 records.
