Question

I have this code in my ASP page:

<%@ Register TagPrefix="genies" Namespace="TheNamespace" Assembly="TheAssembly"%>

...

<% string name = GetTag().Name; %>
<div class="<%= name %>"></div>
<genies:BarGenie ID="BarGenie1" runat="server" Title="<%= name %>" />

The BarGenie class has the following code:

public class BarGenie : Control {

    public string Title { get; set; }

    protected override void Render(HtmlTextWriter writer) {
        writer.Write("<div>" + Title + "</div>");
    }

}

This is the HTML that is generated:

<div class="E00383"></div>
<div><%= name %></div>

I’d like to see this HTML:

<div class="E00383"></div>
<div>E00383</div>

I’ve tried various things in the ASPX code: @name, <%# name %> etc but I can’t figure out what’s going on. Is there some other way of inserting a custom control that I should be using? Do I have the wrong approach to using this custom control?

Answer 1

Try this replacing the <%= %> tags with <%# %> and adding a call to this.DataBind(); in your codebehind.
