ASPX add HTML content programmatically

Question

I have a simple ASPX page that inherits from MasterPage:

(Popup.master)

<div class="text_container">
    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">    
    </asp:ContentPlaceHolder>
</div>

(Privacy.aspx) Privacy

<asp:Content ID="BodyContent" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

</asp:Content>

I need to add a HTML content inside the Privacy.aspx.cs:

public partial class Privacy : System.Web.UI.Page
{
    protected override void OnPreInit(EventArgs e)
    {
        ContentPlaceHolder body = (ContentPlaceHolder)Master.FindControl("ContentPlaceHolder1");

    }

    protected void Page_Load(object sender, EventArgs e)
    {

    }
}

I saw this example but as I see I need asp control inside. How to add just HTML content to ContentPlaceHolder1?

Answer 1

A ContentPlaceHolder is intended to give you the ability to add controls in your page markup with a Content control and have them appear within the context of your master page. Given that, in Privacy.aspx you can add a generic html control in BodyContent Content Control and set the InnerContent property on the added control within your code behind.

Markup

<asp:Content ID="BodyContent" ContentPlaceHolderID="ContentPlaceHolder1" 
             runat="server">
    <span id="SpanContent" runat="server"></span>
</asp:Content>

Code Behind

protected void Page_Load(object sender, EventArgs e)
{
     SpanContent.InnerHtml = "<b>Hello!</b>";
}
