Question About RadAsyncUpload Demo

I have reviewed the Upload Async demo (the overview). Telerik describes this demo as a "simple mail app mockup" and the AsyncUpload is used to add "file attachments". Within the demo, I clicked [Select] to "attach" a file. The demo also displays a default email address of john@johnsmith.com. I replaced this address with my own and clicked [Send], expecting to receive a message in my Inbox that included the file attachment. I never received a mail message (after several attempts).

Can someone explain how this demo is intended to work?
Is it suppose to send email?
If it is suppose to send email, is it also suppose to include a file attachment?
Can I change it so that it emails a hyperlink to a file that was uploaded to my webserver, instead of physically emailing an attachment?

I want a hyperlink (of the uploaded file) to be embedded in the mail message so that when a user receives the mail message, they can simply click on the hyperlink, and have it prompt the user to download the file from my webserver.

Can this be done? How?

Thank you,
Steven

Webservice called two times with LoadOnDemand + EnableVirtualScrolling

Hi,

(I am using the 2012.3.1205.40 version.)
I think I figured out a weird issue with the RadComBox when used with LoadOnDemand + EnableVirtualScrolling.
I bind my RadComboBoxes with a WCF Webservice and has been surprised to see that it is called two times:
- when I open the drop down panel (normal)
- but also after I selected an item.

I checked your demo and it worked as expected.
Finally I detected that it was the MaxHeight property that makes the RadCombobox to call the WCF Webservice two times.

Code:

<telerik:RadComboBox ID="ddlCustomer" runat="server" ClientIDMode="Static" EnableLoadOnDemand="true" MaxHeight="200"

ShowMoreResultsBox="true" EnableVirtualScrolling="true" EmptyMessage="Type here ..." >

<WebServiceSettings Path="~/TestWS.svc" Method="LoadCustomersOnDemand" />

</telerik:RadComboBox>

<telerik:RadComboBox ID="ddlCustomer2" runat="server" ClientIDMode="Static" EnableLoadOnDemand="true"

ShowMoreResultsBox="true" EnableVirtualScrolling="true" EmptyMessage="Type here ...">

<WebServiceSettings Path="~/TestWS.svc" Method="LoadCustomersOnDemand" />

</telerik:RadComboBox>

The first RadCombobox calls my WCF Webservice two times, whereas the second one behaves normally (only one call).

Moreover because it is called two times, when you try to get the selectedItem after the second call, it returns null:

$find("ddlCustomer").get_selectedItem()

Can you check and confirm that?

Rad RadToolTipManager in VB

I am using Rad Calendar in my vb project. I am trying to display the meeting details on the tooltip.

I am trying to import Telerik.Web.Examples.ToolTip.ToolTipCalendar using:
But it is showing error. Kindly suggest. I had used the same logic in C#. It is working fine there, but it is not working in vb

Imports Imports Telerik.Web.Examples.ToolTip.ToolTipCalendar

I am using the following code in my default.aspx.vb file:

Protected Sub RadToolTipmanager1_AjaxUpdate(sender As Object, e As ToolTipUpdateEventArgs)

Dim details As AppointmentDetails = DirectCast(Me.LoadControl("../Admin/UserControls/AppointmentDetails.ascx"), AppointmentDetails)

details.AppointmentID = e.Value

e.UpdatePanel.ContentTemplateContainer.Controls.Add(details)

End Sub

Also i had created a user control AppointmentDetails.ascx.vb

Imports System.Web.Security

Imports System.Web.UI

Imports System.Web.UI.WebControls

Imports System.Web.UI.WebControls.WebParts

Imports System.Web.UI.HtmlControls

Imports System.Drawing

Imports System.IO

Namespace Telerik.Web.Examples.ToolTip.ToolTipCalendar

Partial Public Class AppointmentDetails

Inherits System.Web.UI.UserControl

Private EmpployeeClass As New EmployeeManager()

Private user As New UserManager()

Private m_appointmentID As String

Public Property AppointmentID() As String

Get

Return m_appointmentID

End Get

Set(value As String)

m_appointmentID = value

End Set

End

Property





        Protected Sub Page_PreRender(sender As Object, e As EventArgs)

            Me.AppointmentsDataSource.SelectParameters("ID").DefaultValue = Me.AppointmentID.ToString()

            GridView1.DataSource = AppointmentsDataSource

            GridView1.DataBind()



        End Sub



    End Class

End Namespace

and the default.aspx file contains

<telerik:RadToolTipManager Width="250px" HideDelay="0" RelativeTo="Mouse" ID="RadToolTipManager2"

runat="server" Position="TopRight" OnAjaxUpdate="RadToolTipmanager1_AjaxUpdate"

AutoCloseDelay="0">

Client edit batch updates - Issue with ReadOnly columns

Hi,

I have a grid on my page which allows users to edit records and do batch updates. I am using the following demo which works just fine. (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/clienteditbatchupdates/defaultvb.aspx?#qsf-demo-source).

However, in my RadGrid I have several bound columns set to ReadOnly and when the users accidentally double click those ReadOnly columns JavaScript errors occur. It seems the errors occur because the JavaScript functions are looking for the editable control (textbox) for every column including the ReadOnly ones.

I tried to modify the JavaScript functions so no “dblclick” handler is added to those ReadOnly columns but I am still getting the errors.

Using the demo specified above, is there any way the ReadOnly columns will be ignored when double clicking the cell?

Using:

RadControls for ASP.NET AJAX Q1 2013
Windows 7
Visual Studio 2010
vb.net
.NetFramework 4.0
SQL Server 2005

Thanks

[Solved] ConfigurationPanel Caption of Fields

Hello Everyone,

I'm having trouble in the following situation:

http://demos.telerik.com/aspnet-ajax/pivotgrid/examples/configurationpanel/defaultcs.aspx
On the Demo page I see a CategoryName & ProductName and so on...

In my application I've got the fields names separated with a "_" sign.

i would like to replace the "_" sign with an empty space " ". ex(Category_name => Category name)

I've tried to alter the column caption on databinding of the pivot grid (server side).
I've searched for a event (server side) prior to the Show of the configuration panel -> non existing.

can someone please point me in an other direction to search for the solution?

server-side save with canvas=yes

Hi

I need to save an edited image server-side in an SQL database. Apparently this does not work correctly with CanvasMode set to 'yes', but I need this set to yes as I am using the new Drawing tools!

Could you please help me achieve this. Is there a way I can successfully retrieve the edited image server-side while using the drawing tools, if not could you help provide me with a work around that perhaps retrieves the edited image client-side and then executes a server-side function that can reference the retrieved image (i.e. client-side place the image contents in a server control, and then call a server side function to save it in a database)?

Any help would be much appreciated.

Regards, Paul
