RadAsyncUpload without temporary file

I would like to use the RadAsyncUpload control without using a temporary file. I just need the stream to pass to another function(e.File.InputStream). How can I accomplish this?

It works for me when I run it in Visual Studio, but fails when I deploy it to the server. I am setting my Temporary Folder to a folder in the HttpContext.Current.Server.MapPath. The user machine will not have that path.

My ascx file:
<telerik:RadAsyncUpload runat="server" ID="RadAsyncUploadLetterFile" AllowedFileExtensions="rtf,rtfb" Width="225px"
OnFileUploaded="RadAsyncUploadLetterFile_FileUploaded" MaxFileInputsCount="1" DisablePlugins="True"
PostbackTriggers="btnUpload" OnClientFileUploadFailed="onClientFileUploadFailed"
EnablePermissionsCheck="False" DisableChunkUpload="True" UseApplicationPoolImpersonation="True"
Skin="Web20" MultipleFileSelection="Disabled" >
</telerik:RadAsyncUpload>

ascx.cs:
public void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
RadAsyncUploadLetterFile.TemporaryFolder = HttpContext.Current.Server.MapPath(@"..\..\Reports");
}
}

TypeError When using on Radgrid Edit

Hello,

Even though we bought the licence recently im getting a javascript error when using a RadListbox in a a UserControl then is called on a RadGrid.

When its called in ASPX, it does not verify the same behavior, in other words all goes well.

The userControl its quite simple

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="IncidenteComentarios.ascx.cs" Inherits="CRM.Ui.Web.IncidenteComentarios" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<telerik:RadToolBar runat="server" ID="ToolBar" AutoPostBack="true" Skin="Windows7">
    <Items>
        <telerik:RadToolBarButton Text="Guardar" CommandName="PerformInsert" CommandArgument="" />
        <telerik:RadToolBarButton Text="Guardar / Novo" CommandName="PerformInsert" CommandArgument="New" />
        <telerik:RadToolBarButton Text="Cancelar" CommandName="Cancel" />
    </Items>
</telerik:RadToolBar>
<br />
<telerik:RadListBox ID="lstRecursos" runat="server" CheckBoxes="true" Width="350px"
    DataTextField="_Descricao" DataValueField="_Codigo" DataKeyField="_Codigo" Height="200px">
</telerik:RadListBox>

At this sample no operations are taken on server.

Thanks

Using RadWordsProcessing in ASP.NET Application

Hi There,

I learned from the following documentation page that there is a RadWordsProcessing feature that can be used to manipulate docx files.

http://www.telerik.com/help/aspnet-ajax/radwordsprocessing-getting-started.html

However, it is also mentioned that reference to the following dlls is required.

• Telerik.Windows.Documents.Core.dll
• Telerik.Windows.Documents.Flow.dll
• Telerik.Windows.Zip.dll

Can I check with you whether it is recommended to reference dll under the namespace 'Telerik.Windows' in ASP.NET projects?

Regards,
Ryan

RadTreeView with Context Menu

Hi,
I have RadTreeView with context menu. The code looks like this.

    
            <telerik:RadTreeView ID="RadTreeView1" runat="server" Style="border: 1px solid #CBE7F5;" 
        
                             OnNodeExpand="RadTreeView1_NodeExpand"  
        
                             OnNodeClick="RadTreeView1_NodeClick"  
        
                             OnClientNodeClicking="OnClientNodeClicking"   
        
                             OnContextMenuItemClick="RadTreeView1_ContextMenuItemClick" 
        
                             OnClientContextMenuItemClicking="onClientContextMenuItemClicking" 
        
                             OnClientContextMenuShowing="onClientContextMenuShowing" 
        
                             > 
        
                             <ContextMenus> 
        
                               <telerik:RadTreeViewContextMenu ID="MainContextMenu" runat="server"> 
        
                                    <Items> 
        
                                        <telerik:RadMenuItem Value="CR" Text="Create Change Request" ></telerik:RadMenuItem>                             
        
                                    </Items> 
        
                                    <CollapseAnimation Type="none" /> 
        
                                </telerik:RadTreeViewContextMenu> 
        
                             </ContextMenus>                  
        
                    </telerik:RadTreeView>

in the contextmenuitemclick event I am accessing the node like this

    
             protected void RadTreeView1_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e) 
        
                { 
        
                    RadTreeNode clickedNode = e.Node; 
        
            }

most of the times the returns a valid RadTreeNode, but after a few clicks or the page is left untouched for a while the e.Node returns null. I suspected Session timeout but it is not. Any ideas on how to resolve this or am I doing some thing wrong? please help.

How to use custom images

Can you please explain or provide an example of how to use custom images?

I am not referring to custom shapes, I would like to use an image such as a PNG as the shape, is this possible? I understand its possible with silverlight and wpf versions of the diagram but I'm using asp.net ajax

I can probably provide my images in the SVG format if that helps

Thanks

Refreshing Sessions to Avoid Timeout

I realize you can just go into IIS and extend the session, or you use javascript to keep the session alive, but I have been requested to find out if there is something within the telerik library specifically that can help with this - ideally something that works well with usergroups. Again I am aware that it can be done without telerik.

If there is, we would like to know about it.

Thanks.
