In the following code if the image button is not inside an update panel it works. If it is kept
inside update panel to avoid page refresh purpose it throws an error like:does not contain a definition for DataItem and no extension method DataItem accepting a first argument of type System.Web.UI.Control could be found (are you missing a using directive or an assembly reference?)

XML

<asp:UpdatePanel ID="popp" runat="server" >
    <ContentTemplate>
    <asp:ImageButton ID="ImageButton1" Height="200px" Width="254px"  runat="server" CommandName="myeventDetails"  ImageUrl='<%#DataBinder.Eval(Container.DataItem,"PicturePath") %>' />
 </ContentTemplate>

Try and register your imagebutton for full postback

C#

ScriptManager.GetCurrent(this.Page).RegisterPostBackControl(btnid);
