    <p>I have run into what seems to be a very famous problem: My updatepanel fires a full postback instead of a async postback. The normal solution is to give all controls you add dynamically an ID, which I have done, but I still get a full postback instead of my async postback...</p> <p>Here's the code:</p> <p>HTML:</p> <pre><code>&lt;asp:UpdatePanel ID="ItemsUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="False"&gt; &lt;Triggers&gt; &lt;/Triggers&gt; &lt;ContentTemplate&gt; &lt;asp:ListView ID="PlayerItems" runat="server" GroupItemCount="5" onitemdatabound="PlayerItems_ItemDataBound"&gt; &lt;LayoutTemplate&gt; ... Listview stuff ... &lt;/asp:ListView&gt; &lt;/ContentTemplate&gt; &lt;/asp:UpdatePanel&gt; </code></pre> <p>The interesting part is the C# code behind (method PlayerItems_ItemDataBound), which is like the following:</p> <pre><code> ImageButton imgBtn = new ImageButton(); imgBtn.ID = "itemBtn"; imgBtn.Width = Unit.Pixel(30); imgBtn.ImageUrl = "~/Images/Game/Items/" + myItem.ItemImageUrl; ContextMenu menu = new ContextMenu(); menu.BoundControls.Add(imgBtn); menu.ItemCommand += new CommandEventHandler(menu_ItemCommand); menu.AutoHide = true; menu.RolloverColor = Color.Gray; menu.ID = "MenuMenu"; Panel panel = (Panel)(e.Item.FindControl("ItemPanel")); panel.Controls.Add(imgBtn); panel.Controls.Add(menu); AsyncPostBackTrigger trig = new AsyncPostBackTrigger(); trig.ControlID = menu.UniqueID; trig.EventName = "ItemCommand"; ItemsUpdatePanel.Triggers.Add(trig); </code></pre> <p>So, I actually add an AsyncPostBackTrigger to the menu, so the ItemCommand event should be registered. What happends when I click an item in this contextmenu, is a full postback happends.</p> <p>I have been trying to play with the ChildrenAsTriggers property without help. I have also been moving the AsyncPostBackTrigger code up and down, also without help.</p> <p>Thanks a lot beforehand..! Lars</p>

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.
