The code can not be included in "form" tag

Scheduler Javascript
#1

Hi all,
I found that the following code can not be included in “form” tag,like this:

<body onload="init();">
   [b] <form id="form1">[/b]
    <div id="scheduler_here" class="dhx_cal_container" style='width: 100%; height: 100%;'>
        <div class="dhx_cal_navline">
            <div class="dhx_cal_prev_button">
                &nbsp;</div>
            <div class="dhx_cal_next_button">
                &nbsp;</div>
            <div class="dhx_cal_today_button">
            </div>
            <div class="dhx_cal_date">
            </div>
            <div class="dhx_cal_tab" name="day_tab" style="right: 204px;">
            </div>
            <div class="dhx_cal_tab" name="week_tab" style="right: 140px;">
            </div>
            <div class="dhx_cal_tab" name="month_tab" style="right: 76px;">
            </div>
        </div>
        <div class="dhx_cal_header">
        </div>
        <div class="dhx_cal_data">
        </div>
    </div>
    [b]</form>[/b]
</body>

the preview page will be blank.
For .aspx file in .net project,all of tags should be included in “form” tag. Would you please give me some suggestion?

May be caused because of

      style='width: 100%; height: 100%;'

try to change those sizes to fixed one.

yes,it’s ok after I change those sizes.

style='width: 800px; height: 800px;'
