Removing </p> tag after ValidationSummary control

I use Visual Studio 2010 in ASP.NET with C# code behind.

I have an ASP.NET page with code in Source View:

<p>
    <asp:ValidationSummary ID="ValidationSummary1" runat="server" />
</p>

If I switch in Design View and come back to Source View in VS, it unexpectedly removes the last </p> automatically.

Do you have the same problem in your Visual Studio? Any ideas how to solve it?

Thanks.

P.S. Here my full code:

<asp:Content ID="Content1" ContentPlaceHolderID="MainContent" runat="server">
    <h1>
        Create Groups Types</h1>
    <p>
        <asp:DetailsView ID="uxCreateGroupsTypesDisplayer" runat="server" AutoGenerateRows="False"
            DataKeyNames="GroupTypeId" DataSourceID="uxEntityDataSourceCreateGroupsTypes"
            DefaultMode="Insert" 
            oniteminserted="uxCreateGroupsTypesDisplayer_ItemInserted" 
            oniteminserting="uxCreateGroupsTypesDisplayer_ItemInserting">
            <Fields>
                <asp:TemplateField HeaderText="TypeGroup" SortExpression="TypeGroup">
                    <InsertItemTemplate>
                        <asp:TextBox ID="uxTypeGroupInput" runat="server" Text='<%# Bind("TypeGroup") %>'></asp:TextBox>
                        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="TypeGroup field is required."
                            ControlToValidate="uxTypeGroupInput" Text="*">
                        </asp:RequiredFieldValidator>
                        <asp:RegularExpressionValidator ID="uxRegularExpressionTypeGroup" runat="server"
                            ControlToValidate="uxTypeGroupInput" ErrorMessage="TypeGroup is too long or short. Change the field accordingly."
                            ValidationExpression="^.{4,40}$">*</asp:RegularExpressionValidator>
                    </InsertItemTemplate>
                </asp:TemplateField>
                <asp:TemplateField HeaderText="Summary" SortExpression="Summary">
                    <InsertItemTemplate>
                        <asp:TextBox ID="uxSummaryInput" runat="server" Text='<%# Bind("Summary") %>'></asp:TextBox>
                        <asp:RequiredFieldValidator ID="RequiredFieldValidatorSummary" runat="server" ErrorMessage="Summary field is required."
                            ControlToValidate="uxSummaryInput" Text="*">
                        </asp:RequiredFieldValidator>
                        <asp:RegularExpressionValidator ID="uxRegularExpressionSummary" runat="server" ControlToValidate="uxSummaryInput"
                            ErrorMessage="Summary is too long or short. Change the field accordingly." ValidationExpression="^.{4,256}$">*</asp:RegularExpressionValidator>
         开发者_如何学Go           </InsertItemTemplate>
                </asp:TemplateField>
                <asp:CommandField ShowInsertButton="True" />
            </Fields>
        </asp:DetailsView>
    </p>
    <p>
        <asp:ValidationSummary ID="ValidationSummary1" runat="server" /></p> <!-- The problem is here - This tag disappear if you switch from source view to design view and back to source view -->
        <asp:EntityDataSource ID="uxEntityDataSourceCreateGroupsTypes" runat="server" 
            EnableFlattening="False"
            EnableInsert="True" EntitySetName="CmsGroupsTypes">
        </asp:EntityDataSource>
</asp:Content>

In VS2008, replaced:

<p>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" /></p>

With:

<p>
<asp:ValidationSummary ID="ValidationSummary1" runat="server"></asp:ValidationSummary></p>

This works, although does not agree with the closing tag in markup. Rendering is correct though in IE8.

Why does this summary control need to be enclosed in a paragraph tag? The Validation Summary renders as a block element.

Don't use Design View to edit markup, always use Source View, i.e. markup itself to edit markup.

IMO Design View just a simple, read-only, verify-purpose view.
