The PlaceHolder control is used to reserve space for controls added by code.

Note

The PlaceHolder control does not produce any visible output! It only acts as a container for other controls on the webpage.

Example MiniNotepadView.ascx file

The MiniNotepadView.ascx file shows the NotePad minicard on the left side

<%@ control language="C#" autoeventwireup="true" inherits="WebParts_MiniCards_MiniNotepadView, SoSixWeb" %>
<%@ Register TagPrefix="so2" Namespace="SuperOffice.CRM.Web.UI.Controls" Assembly="SuperOffice.CRMWeb" %>
<asp:PlaceHolder ID="notepadPlaceholder" runat="server" />
<div runat="server" id="buttonwrapper" style="position:absolute;bottom:0px;">
  <asp:HyperLink ID="prev" runat="server"><</asp:HyperLink>
  <asp:PlaceHolder ID="infoPlaceholder" runat="server" />
  <asp:HyperLink ID="next" runat="server">>sp:HyperLink>
</div>

Two placeholders are used in the above code and their IDs are notepadPlaceholder and infoPlaceholder.

Controls are dynamically added to the above placeholders in the coding of the MiniNotepadView.ascx.cs file.
