    <p>I'm writing item template for repeater in separate control, and then I'm using following code:</p> <pre><code>HospitalRepeater.DataSource = LocationsList; HospitalRepeater.ItemTemplate = Page.LoadTemplate("~/UserControls/HospitalDetails.ascx"); HospitalRepeater.DataBind(); </code></pre> <p>This code worked fine, however now we want to add custom events to HospitalDetails control.</p> <p>We created following event with custom event args:</p> <pre><code>public class HospitalItemEventArgs : EventArgs { public Int32 HospitalID { get; set; } public HospitalItemEventArgs() { } public HospitalItemEventArgs(Int32 hID) { this.HospitalID = hID; } } public event EventHandler&lt;HospitalItemEventArgs&gt; HospitalAction; protected virtual void OnHospitalAction(HospitalItemEventArgs e) { if (HospitalAction!= null) this.HospitalAction(this, e); } </code></pre> <p>Now here is a problem - I can't access this custom event from my code after loading this control as template, because it returns object of System.Web.UI.ITemplate. I assumed that this is wrapper above my exact control, but this assumtion is wrong.</p> <p>Cast to my control type fails with following error message:</p> <pre><code>Unable to cast object of type 'SimpleTemplate' to type 'UserControls.HospitalDetails'. </code></pre> <p>I've tried reverse action - load control using</p> <pre><code>Page.LoadControl("~/UserControls/HospitalDetails.ascx"); </code></pre> <p>It returns object of correct HospitalDetails type, but It does not implement ITemplate interface.</p> <p>Whan I tried to do that I've received error message:</p> <pre><code>Unable to cast object of type 'ASP.usercontrols_hospitaldetails_ascx' to type 'System.Web.UI.ITemplate'. </code></pre> <p>Can anyone help me to deal with this cast, or find another solution which matches following requrements:</p> <ul> <li>Repeater should be bound to list of HospitalItems to display details.</li> <li>Template for displaying details should hide it's UI interactions and expose few simple events like HospitalAction with hospital ID.</li> <li>Separate object must have ability to subscribe to this events.</li> </ul>

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.
