Delete slow (free version)

Suite and Optimus Suite 5
#1

I have a grid that has several thousand entries in it. I want to delete a couple of hundred rows at a time. Currently I have a loop that deletes each row, but it is extremely slow. When I tried to use the enableSmartRendering() I get an error message that the method is not defined. I am using the free version , and the API does not list this method as being only in the Pro version. What should I look at now?

If you want to delete all rows from the grid better to use mygrid.clearAll() or enable fast mode:

#3

grid.startFastOperations()
deleting…
grid.stopFastOperations()

You need to include dhtmlxgrid_fast.js. In such mode events are not generated, some time consuming actions applied only once, which allow to increase performance

Free version of dhtmlxGrid allow only dinamically smart rendering mode. Please see example here dhtmlx.com/docs/products/dhtmlxG … d_dyn.html

I do not see the file dhtmlxgrid_fast.js anywhere in the codebase.

Must be stored as
dhtmlxgrid/codebase/ext/dhtmlxgrid_fast.js
