Spell checker fails with .NET 4.0

I have a basic page with Telerik Editor on it, with spell checking enabled. The page worked fine in .NET 3.5 - spell checking and all, but since migrating the code to .NET 4.0 RC the spell checking functionality fails with the following error:

A potentially dangerous Request.Form value was detected from the client (CommandArgument="<br>").

What do I have to do to make this with with .NET 4.0?

Thanks

Truncated labels

Ok, putting the actual label in a tool tip is kind of cute, but it isn't a good idea when they want to print or copy the graph...
How do I get it to stop truncating the labels???

[Solved] Empty RadGrid Shows No Columns

I want to create a RadGrid to use like a spreadsheet, where users can fill in the cells, add rows, and delete rows. We're doing that now with an Infragistics grid, which I want to replace. I've attached a pic of what it looks like, which I now want to do with a RadGrid (but with a comboxbox in the "Cost Center" field now).

After I created the columns, I ran the webpage, but the grid is blank -- it doesn't even show the column headers. All I want is an empty row for the user to enter values into (like my attached pic shows) after which they can add or delete rows. (I'll save/load the data into the grid later.)

My RadGrid is defined below, with various ColumnType and DataTypes. But when I run it, there's no grid on the page. What am I missing? Or is RadGrid meant only for display purposes? I found none of your demos allow the spreadsheet-like editing of cells, so am I using the wrong control?

    
                    <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" GridLines="None">

2) Add Play and Stop button - Play for Autoscroll

Hi,
I have a problem in viewing text in the PDF file. I have 3 hyperlink controls as the following aspx code sicne my project scenario is like that. In viewing the text of the controls in Grid has no problem. But in PDF file the position and text has been changed.

                                        <ItemTemplate>   
        
                                            <asp:HyperLink ID="URL" Text='Title1' runat="server"></asp:HyperLink>                                                                                    
        
                                            <asp:Literal ID="literalUrl1" Text='Title2' runat="server"></asp:Literal> 
        
                                            <asp:Literal ID="literalUrl2" Text='Title3' runat="server"></asp:Literal>                                  
        
                                        </ItemTemplate>

Export to Excel, Grid Visible Set False

Hello, I have a situation where I need to export a lot of data, however, I need to show only a few columns in the grid. I tried adding all of the fields to the grid but have them invisible, however they do not then export. Not thinking it would work I created a second grid and set it to visible false and of course I was right it did not work, I tried putting the grid in a table cell with a height of 0px but it expands for the grid anyway.

Basically, I need to export around 40+ fields to excel but I want to only show 5 in the grid on the page.

Is this possible or is there a workaround?

Webservice Connection Refused

Hi All

I have developed a web app using a webservice. Everything works fine in the development environment. I have moved the webservice to the production server in a test folder behind my main website. I can browse to the published service localy on the production server and i can access the remote service from my development machine.

If I run my web app in my development environment I can use the remote webservice no problem. If I move the web application to the production environment the browser outputs this error when the application performs the ajax login method.

The following javascript error is output to the browser
