Questions on UI for ASP.NET AJAX Forum

I was recently playing around with the Sitefinity demo and I really love the way you can drag and drop controls onto the page from that sidebar. I was wondering how you implemented the drag and dropping part?
I am trying to implement this on a project of my own, I am attempting to drag a div (it doesn't have to be a div it could be almost anything) from a RadWindow and drop it in a RadDock or RadDockZone on the RadWindow's parent page. I did some research on dragging and dropping div's and stuff with javascript but from what I've read that won't work for me at all because I am trying to do it across windows. Any suggestions would be greatly appreciated.

Ajax, Post and whats sent

Using fiddler and viewing whats being posted during an ajax post i can see the view state and then all the __event hidden fields. After that i can see the id's of controls and values e.g. ctl00_BodyContent_ConsentTree_ClientState=%7b%....

Why are the ctl00_BodyContent_ConsentTree_ClientState... etc being added to whats being posted back?

Are these controls duplicated in the viewstate thats being posted back?

Can we send the post without them?

I have read the article http://www.telerik.com/help/aspnet/ajax/ajxtelerikajax.html and viewed the text below.

So if we didn't post back the ctl00_BodyContent_ConsentTree_ClientState....etc we wouldn't be able to access there current values?

http://www.telerik.com/help/aspnet/ajax/ajxtelerikajax.html
Persistence of form values - all form values are sent to the server for processing during the AJAX request and are persisted between AJAX requests. All form controls can be referenced in the code-behind as if a postback occurred. This feature guarantees that your AJAX-enabled applications will not be limited to mere rendering of controls with AJAX, but can cover even the most complex scenario.

on hover of page number/group show next row column value

On my radgrid (2009q3), I have paging turned on.

I have a requirement that states when the users hovers mouse pointer over the page number, that it should display a tooltip showing the contents of the sorted column on that page. When it is a group of pages (11-20), it should display the contents of the sorted column on the first page of the group.

With this functionality, they can navigate to the desired page with less clicking and paging.

I do not find such a feature in the radgrid, can someone suggest a way to accomplish this?

TIA.

Grid / Edit on Double-click issues

I have developed a screen similar to http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/editondblclick/defaultcs.aspx. I want to make it work in such a way that the cell value is saved when a click is made anywhere on the page.I am able to edit the cell by double cliking the cell. I am able to save the edited value when i click on a grid row. When i click on any area apart from the grid, the value is not getting saved. I want to make it work in such a way that the cell captures value when a click s made anywhere on the page. Please help me asap.

Awaiting your reply,
Baarat

"undefined" showing in empty DropDownList

Hi,

after adding the RadFormDecorator to my project MasterPage, I've noticed this strange behavior: in every DropDownList that doesn't have any element, the word 'undefined' is displayed.

Here's a simple page that shows this behavior:

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

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

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >

<head runat="server">

<title>Untitled Page</title>

</head>

<body>

<form action="Default.aspx" runat="server">

<telerik:RadScriptManager runat="server" id="sm1"></telerik:RadScriptManager>

<telerik:RadFormDecorator ID="RadFormDecorator1" runat="server" DecoratedControls="all" />

<asp:DropDownList runat="server" ID="ddlEmpty" Width="150px"></asp:DropDownList>

<asp:DropDownList runat="server" ID="ddlPopulated" Width="150px">

<asp:ListItem Text="Item1" Value="Item1"></asp:ListItem>

<asp:ListItem Text="Item2" Value="Item2"></asp:ListItem>

</asp:DropDownList>

</form>

</body>

</html>

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

namespace DropDownList_undefined

{

public partial class _Default : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

}

Is there any way to avoid this?

Thanks

RadScriptManager

Dear Support,

I want to use Javascript Intellisense. On my master page I added the RadScriptManager (I'm using VS 2010) with the needed references. When I try to use the js intelisense everything works fine.

But how can I add this behaviour on content pages and embedded user controls? I can't add another RadScriptManager, becauce omly one is allowed. But there isn't a RadScriptManagerProxy.

How can I get out of this?

Thanks in advance.

Greetings
Christian

p.S: What means "Use ScriptManager CDN"? What's CDN?
