copied!<p>If you want to use a <code>UserControl</code>, it would be fairly easy. Here's a basic outline.</p> <p>Let's assume you create a user control file <code>FormattedTitle.ascx</code> and code behind file <code>FormattedTitle.ascx.cs</code> in your root folder. </p> <p><strong>Markup would be as follows:</strong></p> <pre><code><%@ Control Language="C#" AutoEventWireup="true" CodeFile="FormattedTitle.ascx.cs" Inherits="FormattedTitle" %> <asp:Label ID="lblTitle" runat="server" /> </code></pre> <p><strong>The code behind for the user control would be as follows:</strong></p> <pre><code>using System; using System.Collections.Generic; using System.Runtime.Serialization; using System.Web; using System.Web.UI; public partial class FormattedTitle : System.Web.UI.UserControl { public string Title { get { return this.lblTitle.Text; } set { this.lblTitle.Text = value; } } public string TitleFormat { get { if(ViewState["TitleFormat"] != null) return ViewState["TitleFormat"].ToString(); return string.Empty; } set { ViewState["TitleFormat"] = value; } } protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); if(!string.IsNullOrEmpty(this.TitleFormat)) { this.lblTitle.Text = string.Format(this.lblTitle.Text, this.TitleFormat); } } } </code></pre> <p>I see the user control usage markup like so:</p> <pre><code><%@ Register TagPrefix="uc" TagName="FormattedTitle" Src="FormattedTitle.ascx" %> <uc:FormattedTitle ID="ftMyTitle" runat="server" Title="Title to Format" TitleFormat="SomeValidDotNetFormatString" /> </code></pre> <p>Not tested, but should get you started. With the above user control, you can set the title and its formatting as properties of the user control.</p> <p>For full background info on string formatting in .net, consider using these resources:</p> <ul> <li><a href="http://msdn.microsoft.com/en-us/library/system.string.format.aspx" rel="nofollow noreferrer">MSDN library article</a> </li> </ul> <p><strong>EDIT</strong>:</p> <p>To answer your question re: multiple tags - do you mean multiple instances of the control on a page? This is actually the nature and purpose of user controls - you can add them as often as needed, such as:</p> <pre><code><%@ Register TagPrefix="uc" TagName="FormattedTitle" Src="FormattedTitle.ascx" %> <uc:FormattedTitle ID="ftMyTitle" runat="server" Title="Title to Format" TitleFormat="SomeValidDotNetFormatString" /> <uc:FormattedTitle ID="ftMyTitle2" runat="server" Title="Some Other Title to Format" TitleFormat="SomeOtherValidDotNetFormatString" /> </code></pre> <p>Is this what you mean by multiple tags?</p>
