Body
I agree with caltrop. I like my markup to be clean and all my aspx/ascx code to reside in my code-behind files (where it belongs). I only have one thing to add. I prefer not to litter my code with OnDataBinding() events wired for each of my databound controls. Instead I do it all in the OnDataBinding() event of the User Control that is being embedded in the bindable-control (such as the repeater in your sample). For example, in my User Control's code-behind you would find: <pre><code>protected override void OnDataBinding(EventArgs e) { base.OnDataBinding(e); litExample.Text = Eval("ExampleField") + " - " + Eval("ExampleField2"); } </code></pre> From here you can set the properties of all your controls or call other methods to set them. Notice how, in my example, I didn't need to perform the boxing like you did here: <code>Literal lit = (Literal)(sender);</code> That alone should save you on some performance (nanoseconds of course, but something worth measure). Read the section "Performance" here: <a href="http://msdn.microsoft.com/en-us/library/yz2be5wk%28v=vs.80%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/yz2be5wk%28v=vs.80%29.aspx</a> I am also at war with using strings in my code. I would have either used const string variables to define "ExampleField" and "ExampleField2" or set them up as public properties in the User Control that could then be set by the containing control/page based on the column name of the data object it will be bound against. This affords more flexibility and re-use of the control. FYI: You don not need to call ToString() on Eval, as this method already returns a string.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
