But in ur example this things is not happening.So how could i solve this problem.here is my code:
<div style="margin:0px;padding:0px;width:800px;overflow:hidden;">
        <table border="0" cellpadding="0" cellspacing="0"
            style="width:800px;height:200px;border:solid 1px #6699CC;">
            <tr style="height:200px;">
                <td runat="server" id="tdTree1" style="width:250px;height:200px;" align="left" valign="top">
                    <div runat="server" id="divTree1" style="width:250px;height:100%;overflow:auto;padding:0px;margin:0px;">
                    <iframe src="Test1.aspx" width="100%" height="100"></iframe>
                    </div>            
                </td>
                <td id="tdMid1" style="height:200px;width:6px;background-color:lightsteelblue;"></td>
