dhtmlx grid filter search box disappear on reloading grid

Hi,

I am facing issue with dhtmlxgrid filter search box. After loading screen and only during first grid load, filter search boxes appear. During second grid load, I am clearing existing data and reloading. This time, I see filter search boxes disappear and only data is loaded to grid.

I am not sure if I am doing anything wrong. Please help me in identifying root cause.

mygrid.setHeader(“col1,col2”);
mygrid.attachHeader("#text_filter,#text_filter");

Regards,
Nitya

Could you please, share with a snippet of your code using to reload the data for the grid or share with a demo link/complete demo, where the problem can be reconstructed.
