    <p>Sure is possible I wrote up articles about imagebuttons and linkbuttons, follow the same form here: <a href="http://weblogs.sqlteam.com/jhermiz/archive/2007/12/10/Cool-Tricks-With-The-ASP.net-Calendar.aspx" rel="nofollow">http://weblogs.sqlteam.com/jhermiz/archive/2007/12/10/Cool-Tricks-With-The-ASP.net-Calendar.aspx</a></p> <p>When you write your event you just need to specify the <code>Handle</code> of that event.</p> <h2>Edit</h2> <p>After thinking about this some more this may in fact not be possible due to the way the asp.net lifecycle functions and how it handles the <code>DayRender</code> event.</p> <p>Even if you do something to this effect:</p> <pre><code>protected void Calendar1_Render(object sender, DayRenderEventArgs e) { if (e.Day.IsWeekend) { DropDownList d = new DropDownList(); d.ID = "bah" + e.Day.Date.ToShortDateString(); d.AutoPostBack = true; d.SelectedIndexChanged += new EventHandler(DropDownList1_SelectedIndexChanged); d.Items.Add("A"); d.Items.Add("B"); d.Items.Add("C"); e.Cell.Controls.Add(d); } } </code></pre> <p>This won't work since the page load event has already fired by the time each day is rendered, so even setting <code>Autopostback=true</code> wont work. </p> <p>In addition even if you assign a new <code>EventHandler</code> to the dynamic control it wont work as in this case:</p> <p><code>d.SelectedIndexChanged += new EventHandler(yourMethod);</code></p> <p>The only thing I can come up with that might work is something to this effect:</p> <pre><code> protected void Calendar1_Render(object sender, DayRenderEventArgs e) { if (e.Day.IsWeekend) { DropDownList d = new DropDownList(); d.ID = "bah" + e.Day.Date.ToShortDateString(); d.Items.Add("A"); d.Items.Add("B"); d.Items.Add("C"); d.Attributes.Add("onchange", "__doPostBack();"); e.Cell.Controls.Add(d); } } </code></pre> <p>The issue is this doesn't fire your server event it only fires a post back, but it gives you an idea that it could fire it via some attributes and client side scripting. Could you change your server method to be a client method? If so this would work, you'd replace <code>__doPostBack()</code> with the name of your client side method.</p> <p>Unfortunately I am not an ASP.net expert, I dab in too many other things, but this information is pretty solid when it comes to the Calendar control, I've used it a lot in the past and got to the point where I had to stop using it due to its limitations.</p> <p>Good luck.</p>

    1. COThanks for the response! I have actually used the article you posted in the past, great stuff. The problem is, the post deals with Images or Literals, I haven't seen a good article on how exactly to specify the handle event in a calendar control. MSDN documentation states: Because the DayRender event is raised while the Calendar control is being rendered, you cannot add a control that can also raise an event, such as LinkButton. You can only add static controls, such as System.Web.UI.LiteralControl, Label, Image, and HyperLink. I'm sure there is a way around this, I just can't figure it out.

    2. CO@user - in my article the controls I add are actually imagebuttons which can cause postbacks so Im not sure which MSDN you are referring to.

    3. COHey Jon, this is the MSDN article [link](http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.calendar.dayrender.aspx) . I looked again at your articles, but I didn't quite see an answer to what I'm trying to do. Even though I'm setting up an event handler for the dropdownlist, its wiped out during the page cycle and I'm not sure how to do it correctly

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.
