I tried to do this with:
arr[i][j] = 'whatever';
but I get some kind of error "cannot convert to object..."

I'm going to guess that you haven't initialized a[i] when you try to treat it like an array. If you haven't initialized a[i] to be an array when you say a[i][j], then it will be undefined (or something else that isn't an array or object) and that doesn't know what [j] means, hence your "cannot convert to an object" error. You need something more like this:
var a = [ ];
for(var i = 0; i < 10; ++i) {
a[i] = [ ];
for(var j = 0; j < 10; ++j) {
a[i][j] = 42; // a[i] is now an array so this works.
}
}

That is wrong. Accessing arrays is done by index position. Same applies to multi dimension arrays. a[indexNumber][indexNumber].

you pushes the array as Arr.push({ TimeSheetID: 0, ProjectID: 1, ProjectName: "Test", TaskName: "My Task", TaskType: TaskType, Status: 0, IsNew: true }); and hence your array object contains 10 records, If you want to change value of ProjectName property at 3rd index then you should write as : Arr[3]["ProjectName"]="xxxxxxx";
