Today, I spent time on using AJAX HoverMenuExtender to display details for Listview items.
I got problem when declare HoverMenu at design time, so I created them on Databound event.
So on the html page
…
<ItemTemplate>
<asp:HyperLink ID=”lblTitle” runat=”server”/>
<asp:Panel CssClass=”detailsPanel” ID=”PopupPanel” runat=”server” style=”display:none;”>
<asp:Label ID=”lblHighlight” runat=”server” Text=”Label”></asp:Label>
</asp:Panel>
</ItemTemplate>
So on the code behind databound method:
HoverMenuExtender titleHme = new HoverMenuExtender();
HyperLink titleLnk = e.Item.FindControl(“lblTitle”) as HyperLink;
Label hightlightLabel = e.Item.FindControl(“lblHighlight”) as Label;
titleHme.PopupControlID = PopupPanel.ID;
titleHme.TargetControlID = titleLnk.ID;
titleHme.PopupPosition = HoverMenuPopupPosition.Right;
titleHme.ID = “hmeTitle”;
titleHme.OffsetX = 5;
e.Item.Controls.Add(titleHme);
Be careful Literal control cannot be used as Target control
