Hint using Drag and Drop, LoadonDemand and Updatepanels for large Trees

Hi,
i am starting a project with two trees on one page, with both drag and drop enabled. It should be possible to drag and drop from one tree to the other one and copy or move the subtrees. Multiselect should be enabled too and no postbacks are allowed.
The trees will have an nodecount up to 6000 nodes.
The tree will be loaded from xml out of an database. There will be an save-button to persist the changes in the tree to the xml / database.
Can someone give me an hint ho to realize this?

Is it possible to use loadondemand with serverclientcallback and draganddrop?
Should i user serverside loadondemand and put the two trees inside updatepanels?
Or should i use clientside dragDrop?
What combination of drag and drop, load on demand and updatepanels is the best for this scenario?

Thank you very much
Christian

resize in firefox overflow problem

Hi,
i am using something like this..
<telerik:RadSplitter ID="RadSplitter1" runat="server">
    <telerik:RadPane ID="RadPane1" runat="server">
        <telerik:RadToolBar ID="RadToolBar1" runat="server" Skin="WebBlue"
        Width="100%" OnButtonClick="ToolbarButtonCommand">
            <Items>
                <telerik:RadToolBarButton runat="server"
                    NavigateUrl="~/Membership/NewUser.aspx" Text="New">
                </telerik:RadToolBarButton>
            </Items>
        </telerik:RadToolBar>
        </div>
        <telerik:RadGrid ID="UsersGrid" runat="server" DataSourceID="dsUsers"
            Skin="Outlook" AutoGenerateColumns="False" AllowPaging="True"
.........................................
my problem is in firefox or radpane that is dynamicly managed by javascript (sized). Now, internal toolbar is causing problems, and resizes only to width of RadPane, that is only initial and not real because of datagrid that goes into overflow area.

Is there any workaround for this? and what do u suggest?

I am experienced with frontend coding and i would like to know, do u in future plan to move to full tableless CSS design because i saw that many of controls (almost most of them) use tables! (this is really bad and doesn't render anywhere correctly).

Export using dynamically created grid

I have a page where I don't need a visual grid, but just want to programmatically create a RadGrid so I can use its export to ExcelML function. I am getting "RadGrid must be databound before exporting." I am calling DataBind(), so I really must be missing something simple here. Any suggestions?

    
                    protected void btnExport_Click(object sender, ImageClickEventArgs e) 
        
                    { 
        
                        DataTable dtExport = ExecTools.General.GetResCodeTreeExport(Application["ExecData"].ToString()); 
        
                        Telerik.Web.UI.RadGrid ExportGrid = new RadGrid(); 
        
                        ExportGrid.AutoGenerateColumns = true; 
        
                        ExportGrid.DataSource = dtExport; 
        
                        ExportGrid.DataBind(); 
        
                        ExportGrid.ExportSettings.Excel.FileExtension = "xls"; 
        
                        ExportGrid.ExportSettings.FileName = "ResCodes"; 
        
                        ExportGrid.ExportSettings.ExportOnlyData = true; 
        
                        ExportGrid.ExportSettings.IgnorePaging = false; 
        
                        ExportGrid.ExportSettings.OpenInNewWindow = true; 
        
                        ExportGrid.ExportSettings.Excel.Format = GridExcelExportFormat.ExcelML; 
        
                        ExportGrid.MasterTableView.ExportToExcel(); 
        
                    }

[Solved] Wrong focus

How can I set the focus onto the texteditor of the editor. The old Editor from Q2 2007 had an autofocus option which worked perfectly but cannot be adapted to the latest version of the Radeditor.
Radeditor1.Focus() in the preRender didnt work.

in Javascript

var

focussedEditor = $find("<%=Radeditor1.ClientID %>");

focussedEditor.setFocus();

Kind of worked but it sets the entire editor into focus and not exclusively the textfield.

What I would like to achieve is that when the editor is loaded the cursor would be in the textfield and the user can start typing instantly.

[Solved] RadEditor provider causes error in DotNetNuke profile

I have implemented the RadEditorProvider in a dotnetnuke 4.8.4 installation.
I though everything went perfectly until I tested the editing of profiles.
When trying to edit my profile I get the following error(Since I have implemented the RadEditorProvider):
The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.

Here is a link to someone who posted the same problem in the dotnetnuke forum but hasn't got a solution yet.
