How to ensure that only numbers between 0 and 100 can be entered in a cell of the grid .
There are two ways to achieve such functionality
a) Create custom excell - you will be able to fully control any behaviours here
or
b) Use onEditCell event, code may look similar to next
grid.attachEvent(“onEditCell”,function(stage,rid,cid,newv){
if (stage==2) //edit end
if (cid==0) // for first column only
if (parseInt(newv)>100) return false; //block values >100
return true;
}
