    Gurus,

    I got multiple rows with same COMBOX BOX ,differentiated with its row ID.

    I am able to get the row id no. But, with rowid when i
    try to get the selection box element length, it fails .

    By doing directly like this, i am getting value.
    ----> alert(doent.forms[0].rowid_1.options.length);

    But with this one gives error,

    ========================================

    var x = 1;
    var rowid = 1;
    var comboid="doent.forms[0].row_" +rowid;
    alert(comboid.options.length);
    ====================

    Error : 'options.length' is null or not an object.
    ========================================


    Please help me to solve this ...(:

    I suggest you specify the value on this line:
    var comboid="doent.forms[0].row_" +rowid;

    I thnik you are pointing to the row while in fact you should be pointing to the
    options collection of the combo box form element...

    doent.getElementById("myComboBoxId").options.le ngth should do it...
