I upgraded the RadControls for ASP.NET to Q1 2009. Everything worked fine. I download RadControls for ASP.NET AJAX version 2009.3 1103 release. I tried replacing a grid with the ajax grid and it tells me of course I needed a script manager. So i added the RadScripManager. When I try to load the page I get the following error.

Unable to cast object of type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection' to type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection'.

I'm sure I have a lot of fluff in the web config file and bin folder, but I really don't know what to change.

Thanks for any help.

[Solved] User Roles in Rad Scheduler

I am using RadScheduler for the first time.

I am trying to understand if its possible to use the scheduler depending on their privileges.
(Well in my case) Could a user only view the scheduler, an admin update / edit / delete / add an appointment (have all the privileges) ?
What would be the best approach to this?

And also any information or a sample on using different tables to fetch data into the scheduler, would be greatly appreciated. I am trying to pull up data into a scheduler depending on different users. And each type of user will be identified by their location and there are admins in that particular location who could modify the events in the scheduler. There are also general admins who could have access to all the locations. So its three different scenarios.

Thanks for your inputs in advance.

Sant.

Always have an empty row in the grid

Hi,

I am using Visual Studio 2008, Rad Conrtols for ASP.NET AJAX Q2 2009 and .net Framework 3.5 and C# Programming.
I am using RAD Grid to display the data and in line mode to edit the data.
i want to always have an emptyrow in the grid so that when the user doule clicks on this empty row, the grid goes into edit mode, user clicks on save and the new row is added.
If there are any rows in the grid already, user can edit the rows by double clicking in a cell and when double click on the empty row user can type in new data.
Thus when clicked on save button, the data in the empty row is added and the data in the other rows is updated.

Thanks,
RKS

Controls in JQuery Postbacks in MVC Views

Hello,

I postback MVC views using JQuery. I have a RadComboBox control within this MVC view that posts back, and replaces the UI, with JQuery code. The control works, but when I replace the content returned from JQuery, the RadComboBox stops working. I'm assuming I need to call $create to make this work... any advice on that?

Thanks.

ArgumentNullException when adding RadDock in Page_Init

Hi,

I'm getting the folllowing error when adding a RadDock control to a RadDockZone in Page_Init.

What I'm doing:

Default.aspx
...uses LoadControl() to load -> Layout.ascx (contains a RadDockLayout with a RadDockZone)
......Layout.ascx then dynamically creates and adds a RadDock to the zone

The error only happens if I load the dock in Page_Init. If I load in Page_Load it works.

The markup from Default.aspx:

    
            <%@ Page Language="C#" AutoEventWireup="true"  CodeFile="Default.aspx.cs" Inherits="_Default" %>

                }  
        
            }

The error I'm getting is:

Exception Details: System.ArgumentNullException: Value cannot be null.

The problem seems to be internal to the RadDockLaout control. Any idea what is happening?

I'll attach the actual files to a support ticket so you guys can try running them.

Thanks.

client-side notification of node.expand()

I use a radTree whose nodes have ExpandMode set to ServerSideCallBack.

At the client-side, I am able to fire _node.expand(); method to actually expand a given treeNode, but I am struggling to find a way for the notification of when the expand operation gets completed. That will help me in accessing the child nodes of a mode in Javascript.

Please let me know if there is any way.

Thanks,

Saurabh.

vertical scroll bar causes found item to reload

2009.3.1103.35 w/IE8

    
            <RadComboBox ID="cbo" runat="server" 
        
                  Filter="Contains" MarkFirstMatch="true" AllowCustomText="false" NoWrap="true"> 
        
            </RadComboBox>

The list has about 500 items and there is NO lazy load involved.
The problem is that after I searched for a name (say 1 found), then I used the scroll bar to scroll down, it seems to go into search mode again and repopulates the display with the same name that was found. (while sort of locking up the IE)

It seems I am hitting the same bug reported here:

http://www.telerik.com/community/forums/aspnet-ajax/combobox/fix-items-loaded-on-demand-can-be-added-multiple-times-on-scroll-q3-2009-issue.aspx

Confirmed this issue is fixed in 2009.3.1201.35

[Solved] RadCaptcha - handlers & httpHandlers related to IIS 7.0 pipeline

Hello,

I'm using IIS 7.0, I would like to ask the difference between the integrated mode pipeline and classic mode pipeline reated to the handlers for RadCaptcha (classic mode works without adding any handlers for RadCaptcha) in web.config? Any performance issue related? Or both just do the same thing?

Here's the handler that I should add in web.config for integrated mode:
<handlers>
<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.CaptchaImageHandler" />
</handlers>

And what the difference between the type's values below:
<add path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.CaptchaImageHandler" verb="*" validate="false" />
