<para>A <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> control defines a relative region for content in a master page, and renders all text, markup, and server controls from a related <see cref="T:System.Web.UI.WebControls.Content" /> control found in a content page.</para>
<para>A <see cref="T:System.Web.UI.WebControls.Content" /> control is associated with a <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> using its <see cref="P:System.Web.UI.WebControls.Content.ContentPlaceHolderID" /> property. Set the <see cref="P:System.Web.UI.WebControls.Content.ContentPlaceHolderID" /> property to the value of the <see cref="P:System.Web.UI.Control.ID" /> property of the related <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> control in a master page. More than one <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> can be declared in a master page. </para>
<para>Within a content page, only one <see cref="T:System.Web.UI.WebControls.Content" /> control can supply the content for a <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> in the master page. However, in each content page that uses a master page, you can have separate <see cref="T:System.Web.UI.WebControls.Content" /> controls associated with the <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" />. For example, you can define the <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> for the page title in a master page. For each content page that uses the master page, you can add a <see cref="T:System.Web.UI.WebControls.Content" /> control that supplies the text and markup for the page title. </para>
<block subset="none" type="note">
<para>For XHTML compliance, an empty title element is created if a title has not been defined or cannot be found.</para>
</block>
<para>You can specify default content placed within the <see cref="T:System.Web.UI.WebControls.ContentPlaceHolder" /> control tags, but this content is replaced by any content in an associated content page. </para>
