Hi ,

Scenario 1:

For this Control, I am using one javascript method populatetime() where  I set the value using  igedit_getById(controlId).setValue('12:15') . But I am getting exception in javascript that mean  igedit_getById(controlId)   returning undefined value .

Scenario 2:

I have another checkbox . if I click on the check box,  , The control time to be more that one Hour  . In onclick event of checkbox I used the same method populatetime() where

I used  igedit_getById(controlId).setValue('13:15')  . Here I am able to get the control with showing time .

    Hi Ganga,

    I suggest you to debug by splitting final expression on one-step statements and check if each of them is valid. For example, you may use alerts:

    if (typeof igedit_getById !== 'function')
        alert('you should wait until javascript files are loaded');

    if (!igedit_getById(controlId))
        alert('you should wait until WebTextEdit ' + controlId + ' is initialized');

    If you will get alerts, then that means that your call to setValue is too early. You may consider to move your statements into page onload or other events. You also may try to use setTimeout, but that can be unstable.
    var controlId = 'WebTextEdit1';
    var val = '12:15';
    setTimeout(function () { igedit_getById(controlId).setValue(val); }, 500);
