Enable/Disable RadNumericTextBox

[Ruth Dahan]

Hi,

I am trying to enable//disable RadNumericextBox using javascript.

I am using the following as I saw in the documentation but i get the error: ntbRetention.enable is not a function

function UseBackupChanged(useBackup,ntbRetentionId) {


    var ntbRetention = document.getElementById(ntbRetentionId);

    if (useBackup == true) {
        ntbRetention.enable();
    }
    else {
        ntbRetention.disable();
    }
}

Can anyone please help what am I doing wrong??

Thanks!

Ruth
