I am using Bryntum Ext Scheduler. The below link is the example i am referring to
http://www.bryntum.com/examples/sche...mnsummary.html

I have to use third header as a frozen row as in example.
For that i have to register viewPreset

Code:
Sch.preset.Manager.registerPreset("hourDay", {
    timeColumnWidth     : 100,
    rowHeight           : 24,
    resourceColumnWidth : 100,
    displayDateFormat   : 'Y-m-d H:i',
    shiftUnit           : "HOUR",
    shiftIncrement      : 1,
    defaultSpan         : 5,
    timeResolution      : {
        unit      : "HOUR",
        increment : 1
    },
    headerConfig        : {
        bottom : {
            unit     : "HOUR",
            renderer : null // set in scheduler initialization
        },
        middle : {
            unit       : "HOUR",
            align      : 'center',
            dateFormat : 'H:i'
        },
        top    : {
            unit     : "DAY",
            align    : 'center',
            dateFormat : 'D d M Y'
        }
    }
});
