Problem on vs2008

Hi Everybody,

I had tried to migrate my web application on vs2008 and I have a problem with prometheus control.
My master contain :
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="Callisto.master.cs" Inherits="Callisto_Callisto" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

                </telerik:RadWindowManager>
            <ContentTemplate>
...

If I let the RadWindowManager, I obtain this error message :

The control with ID 'MainMasterPageWindowManager' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
InvalidOperationException: The control with ID 'MainMasterPageWindowManager' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.]

If I delete the RadWindowManager, it's ok and my page work fine (with radtoolbar and radpanelbar). I have the same problem with a page contain radscheduler.

My Telerik Prometheus version is 2007.2.1107.0

Anybody know if it's an incompatibily, and if it's yes, when Telerik will make a new version ?

Thanks,
Bilou

Ajax on ComboBox

I have an Ajax call fired on selecting a value in a ComboBox. During the Ajax call (which lasts for a few seconds), if I try selecting a value in another ComboBox (non-ajax), the latter ComboBox hangs after the completion of the ajax call. Why is this so?

Viewstate becomes corrupted after insert

Hi,

I have a page with some inputs on the top and three grids at the bottom. The three grids show a list of addresses, the patient responsible for the patient I am viewing, and a list of dependents for the patient I am viewing. Each of these has a custom form that appears inside the grid when I want to add a new record.

The first grid (addresses) inserts just fine. I have no problems after inserting.
The second and third grids seem to corrupt the viewstate after I have inserted a record. Now, I am able to insert a new record, but after there is one item in either grid I cannot post any more to this page. This includes clicking the "Add dependent" or other link button in my grid command template or on my page, and it also includes saving the input at the top. The page becomes uneditable after an item is populated into either table. Even a clean refresh of this page doesn't help.

I must be doing something wrong in the second and third grids, but I can't figure out what. Is there ever a case where the RadGrid will cause an invalid viewstate if there is a record in it?

I can provide sample code as needed. Thanks.

PanelBar Animations

Hi, I really like the style of this type of panelbar and wondered if it is possible to reproduce with telerik controls:

http://www.runningmap.com

(enter a location at the top left to enable panelbar options)

It's very similar to
ExpandMode="FullExpandedItem"
ExpandAnimation-Duration="100"
ExpandAnimation-Type="None"

However, when in FullExpandedItem mode, their panelbar doesn't resize the whole panel, just animates the movement of the bars, whereas ours redraws the whole panelbar which causes random flicker and doesn't look nearly as nice.

regards
ewart

Expand/Collapse arrows disappear

I have a sub-grid in my grid and the arrows used to expand and collapse the sub-grids disappear when I page. If I refresh the browser they appear again. They also disappear if I group, sort, expand, etc.

Any ideas?

Update: It isn't just the arrows that are disappearing - many of the images associated with the Vista style that I'm using disappear as well.

It seems to be all of these guys that are disappearing...

[Solved] Page Count Bug (Sticks at largest count)

I noticed that when I bind a recordset of 100 records the pagecount says there are 10 pages.

If I then bind a larger recordset of say 1500 records the pagecount says there are 150 pages.

Then binding a recordset of 80 records shows a page count of 150 pages.

So it appears that the page count is 'sticking' at the highest pagecount between 'Rebind()' calls with different sized datasets.

My RadGrid is inside a RadAjaxPanel.

Thanks for any help.
