Hello Sir/madem,
I have a TabContainer with one Tabpanel in my Asp.net page.When i modify tabPanel from page design then some unwanted code are added in Source code just below the end of <contentemplate> tag in that TabContainer and show error.why does it do.please help me and suggest me a solution with explanation.
Thanks.

My TabContainer named "TabContainer1" have one tabPanel named "TabPanel1". When i modify it from Designer of page then in source Code automatically adds the same TabContainer and same TabPanel with Same Names and Same Ids and adds other tags just below the ContentTemplate tag of TabPanel.

After modifying it my page looks like this :

C#

<div>
         <cc1:TabContainer ID="TabContainer1"  runat="server" ActiveTabIndex="0" Height="300px"
            Width="950px" AutoPostBack="True">
            <cc1:TabPanel  runat="server" HeaderText="TabPanel1" ID="TabPanel1" Height="300px">
                <HeaderTemplate>
                    <span><font weight="Bold">Contact Details</font></span>
                </HeaderTemplate>
                <ContentTemplate>
