copied!<p>Assuming I understand you correctly it sounds like you should be using a UserControl.</p> <p>Basically create a UserControl.ascx file (and VS will generate the UserControl.designer.cs and code-behind classes for you). Then put your input fields in there with no special attributes, like so:</p> <p>(Note that I prefer HtmlControls to WebControls, they give cleaner markup and don't muddy things. I suggest you give them a try):</p> <pre><code><%@ Control blargh %> <label for="<%= Street.ClientID %>">Street address</label> <input type="text" runat="server" id="Street" /> <br /> <label for="<%= City.ClientID %>">Town / City</label> <input type="text" runat="server" id="City" /> <br />  </code></pre> <p>Note how I'm not messing with the <code>id=""</code> attribute of the input controls. Now just register it in your web.config:</p> <pre><code><add tagPrefix="foo" tagName="Address" src="~/Controls/Address.ascx" /> </code></pre> <p>Then in each page that needs an address form (assuming your UserControl is called AddressControl)</p> <pre><code><%@ Page blargh %> <p>Enter your address details below:</p> <foo:Address runat="server" id="Address" /> </code></pre> <p>Then in your page's code-behind you can just do this:</p> <pre><code> public override void OnLoad(Object sender, EventArgs e) { if( Page.IsPostBack ) { Validate(); if( Page.IsValid ) { // get values from a POST String street = this.Address.Street.Value; String city = this.Address.City.Value; // and so on } } else { // set values if you're retrieving data from a DB or something this.Address.Street.Value = "123 Fake Street"; this.Address.City.Value = "Frying Pan City"; } } </code></pre> <p>Note how I used the "<%= Street.ClientID %>"-thing. ASP.NET will automatically generate the control names and IDs based on the control's parent name (and so on, recursively). So the actual HTML input will be rendered like this:</p> <pre><code><label for="Address.Street">Street address</label> <input type="text" name="Address_Street" id="Address.Street" /> </code></pre> <p>Note this design and practice only applies to WebForms. ASP.NET MVC is completely different again.</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
