I inherited a .NET website using RadAjax.Net2.dlls. Currently only supported in IE compatibility mode from my understanding. I would like to upgrade to a version that works in current browsers. The website is using .NET 2.0 but we are upgrading the framework to 2.8 if possible. I appreciate any recommendations on upgrade path.

Greetings,
I am currently working on an ASP.NET WebForms application, which uses a Telerik RadTreeView.
The treeview uses has the tri state checkboxes active and gets populated server side. We first create a tree of stations (around 2500), which can contain other stations. After that, we populate the tree with datapoints by iterating over all stations and adding the datapoints with the Node.Add() Method.
So the structure is as follows:
Station
- Station 1
- Station 2
- Station 4
- DataPoint
- DataPoint
- Station 5
The checkboxes are used to show if any datapoint is already selected in the treeview and to select additional datapoints for a grouping.
There are multiple groups which can be switched between to see a different selection in the tree.
Therefore, it is necessary to add every datapoint that was already selected (and saved) to show the tri-state checkboxes correctly on page load.
After that a load on demand is possible.
What I tried so far:
- Loading the stations and inserting the datapoints (20k objects) before adding the root node to the RadTreeView
- Building the station tree is fast, but adding the root node to the RadTreeView Control takes about 600 seconds
Loading the stations and inserting the datapoints (20k objects) after adding the root node to the RadTreeView
Building the station tree is fast, but addings the nodes the the RadTreeView Control takes a long time
- Loading the stations and adding the minimal amount of datapoints to display everything checked correctly with tri state checkboxes
- Building the station tree is fast, but on every change of the grouping the tree will be walked completly to attach datapoints which were selected in the new grouping but where not present from the older groupings (or loaded on demand)
So my question is, is there a faster way to load about 20k objects into the tree, so on the change of grouping no new datapoints need to be loaded?
Or am I thinking this very wrong currently? Thank you in advance!

Hi, my grid has many columns and some of them have very long header texts.
I already set <Resizing AllowColumnResize="true" AllowResizeToFit="true" ResizeGridOnColumnResize="true" />
However the header text are still clipped.
I would like to set the long header text to be shown as whole instead of clipped.
Please help! Thanks!

Hello,
Putting a calendar control in a center pane with vertical & horizontal splitters:
I would like to understand if the calendar control can be forced to expand horzontally (taking up 100% of width at all times) as the vertical splitter bar expands. It appears the calendar does grow vertically as the horizontal splitter bar expands.
Thanks!

Hi i have a tab strip & a number of page views associated with it.
what i've also got is some .net buttons which allow the user to also navigate through the tabs if they wish, like a next and previous.
I'd like to disable the previous button when the user is on the first tab and disable the next button when they're on the last tab.
hopefully that makes sense, i want to do this without having to do a postback which i'm sure is possible.
I suppose it would be some code that goes into the buttons Enabled attribute, something like Enabled=' if currenttab = firsttab then false else true' in the example of the 'previous' button.
Many thanks
Alan

The minimum code. Why radwindow can show, let's say "bing.com", "www.wikipedia.org", but refused to show "google.com" and even "telerik.com". Even telerik demo gives "www.google.com refused to connect", or "www.telerik.com refused to connect"

When right clicking on a scheduler's day, for instance, I can click on "New Appointment", and the popup box with "Options", "Cancel", etc. shows up to specify the Subject and/or options. Is there a way I can just click "New Appointment" and bypass that popup, and just create the new appointment? The box below is what I want to completely bypass. Any help is appreciated.

Edit: Looks like I posted this in wrong place. Now posted in feedback and bugs.
When assigning multiple resources and percentages, the first item in list always goes back to 100%.
It saves back to UI correctly but as soon as you leave or refresh page it goes back to 100% on first item and that's what's saved in database.
The online demo has the same code but demo doesn't save at all.
See attached screen shots.

I have a bound grid that contains an image. Since the image is about the size of a thumbnail...I want to give the user the ability to click the image and have it displayed in full. I figured a good way to do this would be to use a RadLightBox. Am I barking down the right path? Is there a better way?
