Setting the response for an Ajax request

I have a very basic question about RadAjaxManager that I was unable to answer yet. How to pass data back to the client-side response handler:

Client-side, I might do something like this:

RadAjaxManager1.ajaxRequest(arg);

Server-side, I then do something like this:

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)

{

string arg = e.Argument;

// do something

}

Client-side, I then handle the response as so

function OnReponseEnd(sender, eventArgs)

{
}

My basic question is - how to pass data back to OnResponseEnd? What can I do server-side that will generate data that I can then process in OnResponseEnd? I'm more accustomed to doing ajax more bare-bones, like through jQuery, where I can pass params back and forth. I know I can add ResponseScripts server-side in order to pass data, but that's a bit clunky.

Thanks

Image editor with dialog opener

hi, I use DialogOpener to open ImageManager directly

    
                    Dim imageManagerParameters As New ImageManagerDialogParameters()  
        
                    imageManagerParameters.MaxUploadFileSize = 1048576  
        
                    imageManagerParameters.SearchPatterns = New String() {"*.jpg", "*.png", "*.gif"}  
        
                    imageManagerParameters.FileBrowserContentProviderTypeName = GetType(wwwBaultar.RadEditorDBContentProvider).AssemblyQualifiedName  
        
                    imageManagerParameters.ViewPaths = New String() {"ROOT/Images"}  
        
                    imageManagerParameters.UploadPaths = New String() {"ROOT/Images"}  
        
                    imageManagerParameters.DeletePaths = New String() {"ROOT/Images"}  
        
                    Dim imageManager As New DialogDefinition(GetType(ImageManagerDialog), imageManagerParameters)  
        
                    imageManager.ClientCallbackFunction = "ImageManagerFunction" 
        
                    imageManager.Width = Unit.Pixel(694)  
        
                    imageManager.Height = Unit.Pixel(440)  
        
                    DialogOpener1.DialogDefinitions.Add("ImageManager", imageManager)

That work great except if user click on the Image Editor I got this error:

Microsoft JScript runtime error: Sys.ArgumentNullException: Dialog Parameters for the ImageEditor dialog do not exist
Parameter name: dialogName

i see some post fot calling the image Editor directly but whats about calling inside the image manager ?
Thanks

Treeview height 100% scrollable with offset

Hello,

I have the following situation. A fixed height treeview (fixed number of items) and below a dynamic treeview with height set to 100%. Body with no scrolling, but scrolling on the treeview. It works just fine except that the 100% takes up 100% screenheight + height of top treeview. I know is is by design of the browsers, but was wondering if anyone might know a fix for it other than setting height clientside with javascript. To reproduce you can use the below code. Thanks in advance:

aspx page:

\r\n are stirpped by rad editor other HTML tags like are diplayed as it is when set from code

when I set the content property of the rad editor with content that has \r\n tags, tags and other html tags,

the \r\n are stripped and the other html tags are displayed as it is in the rad editor.

I set the code like this,

RadEditor1.Content = encodedString;

in the rad grid I get the result as follows,

<pre> <h1>My First Heading</h1> My first paragraph. Dear Dr. <<Contributor's name>>, On behalf of the Primary Care Department at UpToDate, I would like to thank you for the work that youve done as an author for us. We are very appreciative of your contributions regarding the topic <<Title of topic>>. This letter follows several attempts we have made to get in touch with you about a very important disclosure request, which is a necessary piece of our editorial process. As you may know, we are accredited to provide CME to our subscribers. In order to maintain this accreditation, we must collect disclosure information from our authors on an annual basis. We have not received a <<previous year>> disclosure form from you, despite our attempts to contact you in this regard. In keeping with our editorial policy and CME guidelines, we are removing your name from our program as author on the <<Title of topic>> topic, beginning with version <<next version>> (to be released in <<month and year>>). Again, thank you very much for participating in the UpToDate program. Sincerely, <<EA's name>> </pre>

the tags are put as it is... and the there is no new lines generated even though the encoded string contains \r and \n

Can the Rad editor Understand HTML tags and render accordingly?

Thanks,
Ramesh

I have a radgrid in my application which is populated using the web method. Now I have to implement the Add/Edit /Delete options. I need the form template edit form to add/Edit.

to show pagination on right side

I want to do couple of things.

want to align First/Prev/Nex/tLast links on right side.
want to show my own First/Prev/Nex/tLast images
Want to grey out these images i.e grey out First Image if current page is first one.
can specify space between 2 images. right now when i define images it gives lot of space between two images.
PagerTextFormat is not working. It should come adjacent to pagination links.

<PagerStyle Mode="NextPrev" PrevPageImageUrl="Img/sectControl_page-prev.gif" NextPageImageUrl="Img/sectControl_page-next.gif" LastPageImageUrl="Img/sectControl_page-last.gif" FirstPageImageUrl="Img/sectControl_page-first.gif" Position="Top" PagerTextFormat="Items {2}-{3}(of {5})" ></PagerStyle>

Thanks,

Google Chrome & IE Differences

Dear Telerik,

We're facing 2 problems that can be reproduced on your demo site: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx

A. Delete All in Chrome keeps HTML Tags
1) Open the above demo page Using IE (Internet Explorer 8)
2) Select all text found in the memo with Ctrl-A or through the Context menu
3) Press Delete to delete All
4) Click on the HTML view, you'll see NO HTML left
5) Repeat the above in Goggle Chrome (latest version 5.something)
6) Click on the HTML view, you'll see some HTML left:

    
            <div style="text-align: center;"><br /> 
        
            <br /> 
        
            </div>

B. New Lines as Paragraphs in Chrome Generates tags
1) Open the above demo page Using IE (Internet Explorer 8)
2) Select all text found in the memo with Ctrl-A or through the Context menu
3) Press Delete to delete All
4) Click on the Design view
5) Select New Lines as Paragraphs option on the side
4) Type 1 then press Enter 2 times then type 2
5) Click the Html view, you'll see:

    
            <p>1</p> 
        
            <p>&nbsp;</p> 
        
            <p>2</p>

6) Now Repeat the above in Goggle Chrome
7) Click on the HTML view, you'll see some HTML left, delete it, so you start with an empty editor
8) Click on the Design view
9) Select New Lines as Paragraphs option on the side
10) Type 1 then press Enter 2 times then type 2
11) Click the Html view, you'll see:

    
            <p>1</p> 
        
            <p><br /> 
        
            </p> 
        
            <p>2</p>

The above 2 problems ares causing us some troubles because of the different behaviour between IE and Chrome.

Please advise on how to solve them.
