I used ajax pagination in grid and put sum_state for footer.
it show me sum of current column and when click to other page, it increase sum when load other pages.
how can I compute sum of all pages column value for sum_state.
excuse me for bad English.
If you are using dynamic loading - you need to provide some fixed value instead of sum auto-calculation ( as grid will not be able to calculate not loaded yet values )
If you are using static paging ( all data was loaded at once ), try to add the code like next
for (var i=0; i<grid.getRowsNum(); i++)
Be sure to place this line before attachFooter command
