RadTreeView for ASP.NET AJAX Not Rendering Properly

I am working on an existing ASP.NET 2.0 web application built in VS2005. Our desktop OS is WinXP (IIS5) and the servers are Win2003 (IIS6). My current issue revolves around a new AJAX RadTreeView that is located within a couple of asp:Panel within a rad:PageView on a content page. Initially the control renders correctly, but after hiding a parent panel that it is contained within, and then making that panel visible again, the controls renders as an unordered list. There are no checkboxes, or style formatting.

In navigating back to the control by making the parent panel visible again, the tree view control does have its visibility set to false initially and once a specific dropdown selection has been selected the tree view is made visible and the nodes cleared and rebound. I’ve debugged and interrogated the tree view from the command window and the nodes are populated both before and after being made visible and not. In fact the improperly rendered view of the control indicates that it is getting the data.

Are there any ideas as to why this is happening? I have played around with the RadAjaxManager to see if different control selections modified the rendered results, but no.

Much thanks, Fred.

Drag & Drop & Sort

Hi,

I am trying to implement a web page where the user can upload x number of photos to web site and allow the user to sort the order of the photo by drag & drop. Because the user will also have to set number of attributes for each photo, I figure that ListView is perfect way to display the info and allow the user to drag entire cell to reorder. In each cell, it will be like this.

[Photo 1, attr 11, attr12] [Photo 2, attr 21, attr21] [Photo 3, attr 31, attr32]
[Photo 4, attr 41, attr44] [Photo 5, attr 51, attr52]

I should be able to drag the photo to move entire cell and put it in different order.

How do I accomplish this? Can ListView handle this or sample code?

RadAjaxLoadingPanel breaks out of scolled pane

Hello,

I'm using a loading panel to cover a RadTreeView in a RadPane. Everything works great normally. But, when the tree gets long enough that you have to scroll down in the pane, and then the loading panel shows, the loading panel extends above the top of the visible pane. This happens, presumably, because the height of the loading panel is tied to the treeview, which is now taller than the pane it's in.

But, how can I fix it... is there a simple way to make the loading panel now break above the top of the pane when I've scrolled down?

Thanks,

Mike

Retrieving the selected time slot

Hello everyone,

I am new to the Telerik controls so this might seem like a very simple question but I've spent the last couple of hours trying to figure this out with no success.

Basically, I created a Scheduler which I'm populating server side with events retrieved from my database. After implementing the server side event handler for the time slot context menu item clicked, I am trying to retrieve the Start date and End date for a selected time slot server side. The issue is that though client side I manage to select multiple empty time slots, then I use the context menu to add a new event and postback server side and handle the event as per the below.

Protected Sub radEventSchedule_TimeSlotContextMenuItemClicked(ByVal sender As Object, ByVal e As Telerik.Web.UI.TimeSlotContextMenuItemClickedEventArgs) Handles radEventSchedule.TimeSlotContextMenuItemClicked

If e.MenuItem.Value = "NewEvent" Then

Session("EventStartDate") = e.TimeSlot.Start

Session("EventEndDate") = e.TimeSlot.End

End If

End Sub

My issue is that the startdate (e.TimeSlot.Start) and enddate (e.TimeSlot.End) is only being populated with the start time and end time of the timeslot I've right clicked. Therefore if for example I select from 01:00 - 09:00, these properties are only populated with a range of 30 minutes which is exactly the range of each single timeslot.

My intention is to retrieve the start time and end time of all the selected slots rather than the time slot I've right clicked only.

Thank you for your time.

Ludwig
