[Solved] Dynamically creating a RadTreeView Error

Hi

When I try to dynamically add a RadTreeView to a page, VS returns a JScript error, inside the Telerik.Web.UI.RadTreeView._preInitialize function.

This is my page :

    
            <body> 
        
                <form id="form1" runat="server"> 
        
                <div> 
        
                    <telerik:RadScriptManager ID="RadScriptManager1" runat="server"> 
        
                    </telerik:RadScriptManager> 
        
                </div> 
        
                </form> 
        
            </body>

my code-behind :

    
            namespace DynamicTreeViewTest 
        
            { 
        
                public partial class _Default : System.Web.UI.Page 
        
                { 
        
                    protected void Page_Load(object sender, EventArgs e) 
        
                    { 
        
                        Telerik.Web.UI.RadTreeView testtree = new Telerik.Web.UI.RadTreeView(); 
        
                        testtree.ID = "testtree"; 
        
                        Telerik.Web.UI.RadTreeNode testnode = new Telerik.Web.UI.RadTreeNode("Node 1"); 
        
                        testtree.Nodes.Add(testnode); 
        
                        this.Controls.Add(testtree); 
        
                    } 
        
                } 
        
            }

VS throws a null exception error, but the text is :

Microsoft JScript runtime error: 'null' is null or not an object

This is the code where the exception is thrown (line indicated) :

    
            Telerik.Web.UI.RadTreeView._preInitialize=function(_219,_21a){ 
        
            var _21b=$get(_219); 
        
            _21b.scrollTop=_21a; <-- Error

            if(Telerik.Web.UI.RadTreeView._isRtl(_21b)){ 
        
            Telerik.Web.UI.RadTreeView._initializeRtl(_21b); 
        
            } 
        
            };

I've downloaded the new version of the controls (2008 Q2 1001), but they cause the same error.

Combined Chart types

Hi.

Is it possible to have a chart where each point is another chart itself?

For example, a bubble chart with each bubble/point being an individual pie chart. (see attached image)

Grouping Titles

How can I get Group Titles (based on the dataset) into my listview?

The H2 in my Group Template doesn't appear to work, but the data IS in the dataset

    
             <telerik:RadListView ID="imageListView" runat="server" onneeddatasource="imageListView_NeedDataSource" 
        
                                             ItemPlaceholderID="mainImagesContainer" GroupPlaceholderID="GroupContainer"> 
        
                            <LayoutTemplate> 
        
                                <asp:PlaceHolder ID="GroupContainer" runat="server" /> 
        
                            </LayoutTemplate> 
        
                            <GroupTemplate> 
        
                                <h2><%# Eval("LibraryName")%></h2> 
        
                                <asp:PlaceHolder ID="mainImagesContainer" runat="server" /> 
        
                            </GroupTemplate> 
        
                            <ItemTemplate> 
        
                                <div class="imageContainer"> 
        
                                    <asp:Image ID="image" runat="server" CssClass="imageItem" ImageUrl='<%# Eval("ImageURL") %>' EnableViewState="false" /><br /> 
        
                                    <asp:CheckBox ID="check" runat="server" CssClass="checkItem" EnableViewState="false" /> 
        
                                    <asp:Label ID="name" runat="server" CssClass="imageName" EnableViewState="false" Text='<%# Eval("ImageTitle") %>' /> 
        
                                </div> 
        
                            </ItemTemplate> 
        
                        </telerik:RadListView>

Is this just not supported?

PDF Exports with Tables and ContentFilter

I am using the built in PDF export functionality of RadEditor, and there's a need to have a table. I've found that because of some issues between the PDF export tool, that a filter needs to be run to add some tags, as per http://www.telerik.com/community/forums/aspnet-ajax/editor/html-to-pdf-shows-blank.aspx and http://www.telerik.com/community/forums/aspnet-ajax/editor/export-to-pdf-doc.aspx

However, when I added the JavaScript code, I get an error on the line:

MyFilter.registerClass('MyFilter', Telerik.Web.UI.Editor.Filter);

The error being 'Telerik is not defined'. I'm not entirely sure if there is an extra requirement to use the registerClass method. There are other Telerik controls on the page, and they do not throw any errors and work as expected without this line of code being there.

Thanks for any suggestions.

loaing view

What am I missing here? I have a Listbox and when the user clicks an Item I'm loading a grid and I'm trying to get the grid to show that loading indication. I'm taking the example from this screen http://demos.telerik.com/aspnet-ajax/ajax/examples/manager/firstlook/defaultcs.aspx

Instead of the Loading that I'm expecting to see the grid disappears for a second then reappears loaded. Is there something else I need to do or set besides the Ajax Manager?

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