    Adding a new Row wth dynamic values


    I want to add a Row which would show the sum of all the values prior to it.
    How can I do that ?Really dont know what to do....
    Ex:

    aaa val1 val2
    aaa 12 23
    aaa 23 45
    Total 35 68
    bbb 10 16
    bbb 16 10
    Total 26 26

    Default try this

    try this


    Hi,

    When you get the response from server, loop thro the corresponding dataIndex and keep

    adding the sum.Add a value to the store which contains the sum. It should work.

    Default use store.insert

    use store.insert


    Add load event listener to your store, so we can start process when store loads:

    Code:
    var store = new Ext.data.JsonStore({
    ..... listeners: {
    load: function(store, records, options){
    var total = 0, rowValue = 0, totalRowRecord;
    for(var i = 0, len = records.length; i < len; i++){
    rowValue = parseInt(records[i].get('value'));
    rowValue = !isNaN(rowValue) ? rowValue : 0;
    if(((i + 1) % 5 === 0) || ((len % 5) > 0 && i === len - 1)){ //for each 5 records or for the last record show total row
    total += rowValue;
    totalRowRecord = new (store.reader.recordType)({ name: 'Total', value: total });
    store.insert(i, totalRowRecord); //insert total row total = 0; //set 0 again
    } else {
    total += rowValue;
    }
    }
    }
    }
    });
    This would probably work, give it a try!
