    Is it possible to get the event id from an eventview page? I'm wanting to create a link to an event handler that needs the id passed as a parameter, but I don't know how to retrieve it from the page. can this be done?

    I opened up a support ticket on this a while ago.  I was trying to build a http handler that would generate an calendar invite for each event.  I was told to extend the ContentView control and generate the property or update and existing control on the page.  I have not gotten it to work yet but I have not tried that much.

    lol this is exactly what I'm trying to do. I've already completed the handler, I just need a way to pass the id into the string. I was hoping I wouldn't have to go this route as I hate to extend the contentview to just retrieve one single property that oughta be there anyway...

    sitefinity team: any chance accessing this property (ID) will be available in the 3.5 release?

    I completed the handler also and it works great.

    Here is what I have created or recieved from Sitefinity tech support for overriding the ContentView control.

    1#region Base overrides 
    3/// <summary> 
    4/// Overridden. Called every time a content item is being set. The method gets 
    5/// the container in which the child controls are located and <see cref="IContent"/> object 
    6/// representing the content 
    7/// </summary> 
    8/// <param name="itemContainer"></param> 
    9/// <param name="contentItem"></param> 
    10protected override void SetItemContent(Control itemContainer, IContent contentItem) 
    12    base.SetItemContent(itemContainer, contentItem); 
    14    // find the link control in the container 
    15    HyperLink addToOutlook = (HyperLink)itemContainer.FindControl("addToOutlook"); 
    17    if (addToOutlook != null
    18    { 
    19        // get the ID of IEvent object 
    20        Guid eventId = FindEventId(contentItem); 
    21        // set the url of the link 
    22        addToOutlook.NavigateUrl = String.Format("~/GetICSFile.ashx?guid={0}", eventId); 
    23    } 
    25    HyperLink addToGoogle = (HyperLink)itemContainer.FindControl("addToGoogle"); 
    26    if (addToGoogle != null
    27    { 
    28        // get the ID of IEvent object 
    29        Guid eventId = FindEventId(contentItem); 
    30        // set the url of the link 
    31        addToGoogle.NavigateUrl = String.Format("~/GetICSFile.ashx?guid={0}", eventId); 
    32    } 
    37#region Helper functions

    49    EventsManager eManager = new EventsManager(cnt.ProviderName); 
    50    IEvent @event = eManager.GetEventByContentId(cnt.ID); 
    51    if (@event != null
    52        return @event.ID; 
    54    return Guid.Empty;

    WELL!! I managed to totally hack this together to work. what I did was drop a user control into the eventview page, then used reflection to navigate back through the eventview to get the item id. once I got that i just needed to use the event manager to grab the event by the content item id!!

    then I just find the hyperlink control I added to the same eventview page and modify it to link to the handler with the event id. TOTALLY WORKS!!

    here's the code behind for the user control:

    using System;  
    using System.Collections.Generic;  
    using System.Web;  
    using System.Web.UI;  
    using System.Web.UI.WebControls;  
    using Telerik.Events;  
    using Telerik.Events.WebControls;  
    public partial class UserControls_Internal_CalendarReminder : System.Web.UI.UserControl  
        protected void Page_Load(object sender, EventArgs e)  
            EventsView view = Parent.Parent.Parent as EventsView;  
            HyperLink lnk = Parent.FindControl("CalendarReminder"as HyperLink;  
            EventsManager mgr = new EventsManager("Events");  
            IEvent ev = mgr.GetEventByContentId(view.SelectedItemId);  
            lnk.NavigateUrl = string.Format("~/EventReminder.ashx?id={0}", ev.ID);  
            lnk.Text = "Save To Outlook Calendar";  

    I can see potentional for all kinds of customization of the content view now that I've found a way to get in there! but are there any dangers to accessing the content this way?

    screen cap of example

    i don't have a live example to show because we're waiting for the new 3.5 sitefinity release to upload all new updates...

    hope this was helpful!
