When double clicking on a scheduler, I want to be able to pass a value to the advanced form so it can use it to grab more values from the database when loading.

Can someone give me an example of how to pass a value to the advanced form? I have already set up properties etc in the advanced form, I'm just not sure how to pass it when double clicking a timeslot in the scheduler for appointment insert.

Thanks in advance.

RadAjaxLoadingPanel -

Hi,

I have started to use RadAjaxManager instead of ASP UpdatePanels to control what section of the page that should be updated.
I also know how to use the RadAjaxLoadingPanel in combination with AjaxSettings to show a loading symbol over different controls (see below).

<telerik:RadAjaxManager>
   <telerik:AjaxSetting AjaxControlID="btnDummy">
      <UpdatedControls>
         <telerik:AjaxUpdatedControl ControlID="pnlToUpdate" LoadingPanelID="RadAjaxLoadingPanel1" />
      </UpdatedControls>
   </telerik:AjaxSetting>
</telerik:RadAjaxManager>
<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server">
</telerik:RadAjaxLoadingPanel>

What I want to achieve now is to show the RadAjaxLoadingPanel loading symbol, but not over a specific control.
For example, I would like to be able to display a loading animation next to a button when pressing that button. How can this be achieved with the RadAjaxManager?

Thanks!

Scheduler performance concerns

I am in the early staging of using RadScheduler. So someone please advise if I may not understand it the right way.
1. I am working a custom sql provider, and override following method:
public override IEnumerable<Appointment> GetAppointments(RadScheduler owner)
from my understanding, all appointments will be loaded, then in the DataBinding event, those appointment filtered by resources will be set to invisible.

In my case, the number of Appointment will be huge, I would like to filter the appointment by resouces in earlier staging, e.g. in the stored procedures. How do I pass in the resources filter in GetAppointments method?

2. Can someone help me on my post at http://www.telerik.com/community/forums/aspnet-ajax/scheduler/user-based-recources.aspx ?
The demo stated that the resource will be cached once retrieved, but from what I saw, GetResourcesByType is being called everytime page is postback. What is the internal cache machenism RadScheduler already inplemented?

Thanks

User based recources?

I am following http://www.telerik.com/help/aspnet-ajax/schedule_databindingimplementingaproviderthatsupportsmultivaluedresources.html to create a custom provider and I have some questions:

I want to create user based resources, i.g. each user can create their own resources, or "tag". Each appointment can have one or multiple "tags". User can sort appointment based on the custom "tags".

In the article, it states that
"Implement the GetResourcesByType method to supply the scheduler with a list of possible values given a resource type. This requires a query to the database to obtain the list of values. Once retrieved, the resources are cached. "

Is it possible to cache the resources based on a userID (a guid) ? Do you provide any interface to override the Cache key? What is the build-in Cache invalidation machenism? If one user modifed his custom resources, how to make it not effect other users resourcs?

Thanks!

Supress ItemsRequested event on key press

I am loading a rad combo box on demand (EnableLoadOnDemand="True") in the ItemsRequested event. I want this to load when the user opens the combo box but not when they type in the combo box (I have MarkFirstMatch = true). Is this possible?

Here is the code I am using for all this if it helps:

<telerik:RadComboBox ID="RadComboBox2" CssClass="DGselectPerson" runat="server" EmptyMessage="Select a Person" EnableLoadOnDemand="True" AppendDataBoundItems="false" AutoPostBack="true" DataTextField="Name" DataValueField="RecordID" EnableVirtualScrolling="true" OnClientDropDownOpening="onDropDownOpening" OnItemsRequested="RadComboBox2_ItemsRequested" MarkFirstMatch="true">

</telerik:RadComboBox>

Protected

Sub RadComboBox2_ItemsRequested(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs) Handles RadComboBox2.ItemsRequested

RadComboBox2.DataSource = GetPeople()

RadComboBox2.DataBind()

End Sub

Missing Data when using with Master Page

When binding data to the RadComboBox utilizing an Ajax panel, the RadComboBox loses its datasource when used within a master page. The RadComboBox is populated on initial load, but after making a selection, it loses the datasource.

My master page markup:

    
            <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Site1.master.cs" Inherits="Management.Web.Site1" %> 
        
            <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
        
            <html xmlns="http://www.w3.org/1999/xhtml">  
        
            <head runat="server">  
        
                <title></title>  
        
                <asp:ContentPlaceHolder ID="head" runat="server">  
        
                </asp:ContentPlaceHolder> 
        
            </head> 
        
            <body> 
        
                <form id="form1" runat="server">  
        
                <div> 
        
                    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">  
        
                    </asp:ContentPlaceHolder> 
        
                </div> 
        
                </form> 
        
            </body> 
        
            </html>

My content page markup (WebForm1):

    
            <%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" 
        
                CodeBehind="WebForm1.aspx.cs" Inherits="Management.Web.WebForm1" %> 
        
            <asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">  
        
            </asp:Content> 
        
            <asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server" 
        
                ViewStateMode="Enabled">  
        
                <telerik:RadScriptManager ID="RadScriptManager1" runat="server">  
        
                </telerik:RadScriptManager> 
        
                <telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server">

                </telerik:RadAjaxPanel> 
        
            </asp:Content>

My non-master page markup (WebForm2):

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="Management.Web.WebForm2" %>

                        <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">  
        
                        </telerik:RadComboBox>

                </form> 
        
            </body> 
        
            </html>

My code behind (of both the content and non-master pages):

    
            using System;  
        
            using System.Web.UI;  
        
            namespace Management.Web  
        
            {  
        
                public partial class WebForm1 : System.Web.UI.Page  
        
                {  
        
                    protected void Page_Load(object sender, EventArgs e)  
        
                    {  
        
                        if (!Page.IsPostBack)  
        
                            this.LoadTags();  
        
                    }  
        
                    private void LoadTags()  
        
                    {  
        
                        TagManager mgr = new TagManager();  
        
                        RadComboBox1.DataSource = mgr.GetAllByModuleId(5);  
        
                        RadComboBox1.DataValueField = "Id";  
        
                        RadComboBox1.DataTextField = "Name";  
        
                        RadComboBox1.DataBind();  
        
                    }  
        
                    protected void RadComboBox1_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)  
        
                    {  
        
                    }  
        
                }  
        
            }

As you can see, the code is VERY basic. The TagManager is a class that returns the data.

When using the Master Page (WebForm1), you lose the datasource after you make your first selection. If you attempt to click on the drop down arrow, after making your initial selection, the RadComboBox is empty (doesn't even respond to the click).

When using the non Master Page (WebForm2), the datasource is persisted no matter how many times you make a selection in the RadComboBox.

Any thoughts why there is a difference when using a master page?
