Hello He peng,

Please try to remove height in TableRow and set the height only in WebToolBar.

<asp:Table ID="mvTable" BackColor="Red" Width="800px" runat="server" CellPadding="0"
        CellSpacing="0">
        <asp:TableRow ID="mvHeaderToolBar">
            <asp:TableCell>
                <ISWebDesktop:WebToolBar ID="mvWebToolBar" runat="server" IntegratedTo="None" Height="40px">
                </ISWebDesktop:WebToolBar>
            </asp:TableCell>
        </asp:TableRow>
    </asp:Table>

Hi Handy

Here is new screenshot.

Hello,

Would you mind to tell me if it is IE8 or not? Please try to press F12 and see the document mode and browser mode.
