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">

</telerik:RadToolTipManager>

<telerik:RadCalendar ID="RadCalendar2" RangeMinDate="3/1/2007" runat="server" Width="100%"

Height="200px" Skin="Default" OnDayRender="RadCalendar2_DayRender" RangeMaxDate="3/30/2014">

</telerik:RadCalendar>

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:

[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
