Questions on UI for ASP.NET AJAX Forum

I've been trying to get a feature similar to this implemented: http://www.telerik.com/community/forums/aspnet-ajax/listbox/onclientselectedindexchanged.aspx

This works fine for one listbox, but after transferring the contents over to the other listbox, the functions do not perform as expected. The checkboxes no longer change, but the selection does. Using the transfer all button to the original side shows that the checkstate actually is being updated. Moving selections back and forth further screw up the code to the point where I'm not sure what it's doing anymore.

Is there any way to accomplish the feature in the above link and maintaining that functionality across the listbox that the item gets transferred to? I have added items to both the source and destination listbox and confirmed that the function is working individually for the listboxes until a transfer happens.

RadAjaxManager And Javascript Issue

Hello there,

I am developing a web application using rad controls. I am using radwindow for popup, in one of the radwindow there is a radbutton with other controls like textbox, dropdown. My requirement is to apply ajaxify and show loading panel after radbutton click.

As a solution I have registered radajaxmanager and radajaloadingpanel on master page.

<telerik:RadAjaxManager ID="rAjaxManagerPopUp" runat="server" >
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="rLoadingPanel" ZIndex="8001" Skin="MyCustomSkin"
        EnableEmbeddedSkins="false" runat="server">
    </telerik:RadAjaxLoadingPanel>

and write this code on aspx.cs

                RadAjaxManager radAjaxManager = Content("rAjaxManagerPopUp") as RadAjaxManager;
                RadAjaxLoadingPanel radAjaxLoadingPanel = Content("rLoadingPanel") as RadAjaxLoadingPanel;
                if (radAjaxManager != null)
                {
                    radAjaxManager.AjaxSettings.AddAjaxSetting(radAjaxManager, pnlPaymentConfirmation);
                    radAjaxManager.AjaxSettings.AddAjaxSetting(radAjaxManager, rBtnSubscribe, radAjaxLoadingPanel);
                    radAjaxManager.AjaxSettings.AddAjaxSetting(rBtnSubscribe, pnlPaymentConfirmation, radAjaxLoadingPanel);
                    radAjaxManager.AjaxSettings.AddAjaxSetting(radAjaxManager, rBtnSaveNSubscribe, radAjaxLoadingPanel);
                    radAjaxManager.AjaxSettings.AddAjaxSetting(rBtnSaveNSubscribe, pnlPaymentConfirmation, radAjaxLoadingPanel);
                }
after these changes I able to show loading panel on Radwindow Popup. But beacuse of these change I am not able to call registered javascript function on aspx.cs
e.g
   String script = "<script language='javascript' type='text/javascript'>Sys.Application.add_load(BillingInfoKeepInEditMode); </script>";
           Page.ClientScript.RegisterStartupScript(this.GetType(), "BillingInfoKeepInEditMode", script);

Please help me to resolved this issue.
its very urgent

Thanks,
Avinash

literal control not updating

The following code works and updates the literal control perfectly. When I add the ajax manager, it doesn't update the control at all. I have tried probably 20 different things. I have tried the manager, the ajax panel, and cannot get this to work. If somebody could take a look at this very simple example and tell me what I am doing wrong, I would much appreciate the help. The literal control should come back with a message - like thank you, email not valid, etc.

Here is the aspx page.

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<ajaxsettings>

<telerik:AjaxSetting AjaxControlID="Button1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Button1"

LoadingPanelID="RadAjaxLoadingPanel1" />

<telerik:AjaxUpdatedControl ControlID="txtEmail" />

<telerik:AjaxUpdatedControl ControlID="litStatus" />

</UpdatedControls>

</telerik:AjaxSetting>

</ajaxsettings>

</telerik:RadAjaxManager>

<br />

<asp:Button ID="Button1" runat="server" Text="Button" />

Email:

<asp:TextBox ID="txtEmail" runat="server" Width="266px"></asp:TextBox>

<br />

<asp:Literal ID="litStatus" runat="server">dddddddd</asp:Literal>

<br />

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" Runat="server"

MinDisplayTime="3000" Skin="Default">

</telerik:RadAjaxLoadingPanel>

Here is the code.

Function AddEmail(ByVal strEmail As String) As Boolean

Me.txtEmail.Text = ""

Dim inputEmail As String = strEmail.Trim.ToLower

Dim bSuccess As Boolean = False

Dim strRegex As String = "^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}" & "\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\" & ".)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$"

'Validate email

Dim re As New Regex(strRegex)

If re.IsMatch(inputEmail) Then

Else

litStatus.Text = "Please enter a valid email to join our mailing list."

'            litStatus.Text = "yeah are already a member.  If you are not receiving our communications, please check your spam folder."

Return (False)

End If

'Open file and add email

Dim xmldoc As New XmlDocument

xmldoc.Load(Server.MapPath("xmlfile.xml"))

'Check to make sure the email doesn't already exist

Dim m_nodelist As XmlNodeList = xmldoc.SelectNodes("emails/email")

For Each m_node In m_nodelist

Dim strEmailNode = m_node.ChildNodes.Item(0).InnerText.ToString.ToLower

'Get the lastName Element Value

If strEmailNode = inputEmail Then

litStatus.Text = "You are already a member.  If you are not receiving our communications, please check your spam folder."

Return (False)

End If

Next

'Append new node and save xml

Dim newNode As XmlElement = xmldoc.CreateElement("email")

newNode.InnerText = inputEmail

xmldoc.DocumentElement.AppendChild(newNode)

xmldoc.Save(Server.MapPath("xmlfile.xml"))

litStatus.Text = "Thank you for joining our mailing list."

AddEmail = True

End Function

Thank You!

Type.registerNamespace("Telerik.Web.UI");

at
if(!$telerik.isSafari){c.outerHTML=null;

I got this error when I selected "pause on uncaught exceptions" in safari
I am trying to deubug. But Still I dont any solution or not sure why this is happening. If I change back the user agent to anything else in Safari, it works fine.

Thanks for the help.

RadGrid Connected to SharePoint 2010 Data with Design Time Support

Does anyone have a good technique for connecting a RadGrid to a SharePoint list while still keeping all the design time features of the RadGrid? I don't. Here's everything I've tried and what sucks about it. BTW, I'm not blaming Telerik. This is more of a VS <--> SP problem.

Using SP Metal, I've create all the classes to connect to my SharePoint data. Now I'm stuck at connecting this to a RadGrid (or even a built in GridView). You have to have a data source to connect to. Logic says that you should use a LinqDataSource. Unfortunately, that control isn't "native" to the SP visual web part template. You'll have to go into the ascx and add <%@ Register Tagprefix="aspweb" Namespace="System.Web.UI.WebControls" Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" %> so that you can use <aspweb:LinqDataSource />. The RadGrid easily connects to the LinqDataSource, but you can't configure the LinqDataSource to connect DataContext object created with SP Metal. The only thing I can find online is using the Selecting event of the LinqDataSource to populate the data, or not using the LinqDataSource and populate the RadGrid's DataSource in the page Load event, or the RadGrid's NeedDataSource event. All of those options destroy the chance to use the nice design-time editor Telerik has designed for the RadGrid.

I've tried this same thing outside of a SP template and had no problems (aside from an annoying Microsoft.Sharepoint.Sandbox.dll file that keeps getting added to the bin\ folder that you have to delete).

Am I missing something? I doubt I'm the only one trying to display SP list data in a grid and use the editor to do my styling. This is driving me up a wall. I've thought about creating all the user controls outside of a SP template and then trying to load those, or creating my own type of data source to wrap around the Metal classes, but this seems a bit too complicated. Am I doing something wrong, or does anyone have a clean solution to my problem?

Finding CheckedNodes on NodeDrop

I have a 2 treeviews lets say tree1 and tree2.
tree1 has checkbox nodes
I drag and drop the checked nodes from tree1 to tree2.
On tree1_nodedrop, trying to read those checkednodes using Tree1.CheckedNodes() and it is always returning 0.
Earlier it used to work, i'm not sure whether is stop working after SP1 installation or VS2012 installation.

Telerik Current Version: 2012.2.724.40 (2012 Q2 SP1)
Code Editor: Visual Studio 2010

Code Behind:
Private Sub tree1_NodeDrop(sender As Object, e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs) Handles tree1.NodeDrop
For Each node As RadTreeNode In tree1.CheckedNodes
