View Full Version : Grid refresh without redraw

22 Feb 2014, 12:44 PM
I have a grid with thousands of records and i'd like to change data seamlessly with lets say every 10
seconds without any loading indicator that's what happens when you reload a store.
I mean like what gmail does when new mail comes.

Is there a way to do this in extjs without any performance loss.

So you want to insert new records only .. you are not concerned with changes to existing data?

Actually my gmail example was a bit misleading.
mostly I am concerned about updates. And let's say there might be 200 records updated every 10 seconds

If you mean you just don't want the automatic loading mask on the Grid, then turn it off in the Grid's viewConfig by setting loadMask (http://docs.sencha.com/extjs/4.2.1/#!/api/Ext.grid.View-cfg-loadMask): false.

Gave it a try but right now since i have very small set of data for testing i couldn't be sure if
store.load locks the grid while loading data. Does it ?

What do you mean by "locks"? If you turn off the automatic loading mask, then there shouldn't be anything blocking the user from using the grid.
