I am currently using static smart rendering but considering getting professional edition so i can switch to paging. My grid has about 2000 rows.
I need to calculate a total for a column in a grid to display it in my custom footer. I am doing it this way.
var size = 0;
size += mygrid.cells2(k,5).getValue()*1;
However first time it takes really long because all the rows are rendered. Is there a way to avoid rendering in this case ?
a) you can use private data access method
size += mygrid._get_cell_value(mygrid.rowsBuffer[k],5)*1;
b) grid has built-in data counters
