Example of how to use an AppointmentComparer

Hi,

Is there any example code setup to show how to use an AppointmentComparer?

I've tried setting one up, but it never seems to get called.

I'm using a RadScheduler with WebService binding, would that have any impact in why it doesn't seem to be working?

In the Page_Init method I have the following code:

    
            RadScheduler1.AppointmentComparer = new AppointmentComparer();

And I have an AppointmentComparer.cs file with the following code:

    
            public class AppointmentComparer : IComparer<Appointment> 
        
            { 
        
                #region Constructors 
        
                public AppointmentComparer() 
        
                { 
        
                } 
        
                #endregion 
        
                int System.Collections.Generic.IComparer<Telerik.Web.UI.Appointment>.Compare(Appointment first, Appointment second)  
        
                {

But the breakpoint in the Compare method never seems to be reached.

Thanks very much for all your help,
Greg

problem deleting text in the design window when "real-time html view" is enabled

The behavior can be seen on the Telerik demo page: http://demos.telerik.com/aspnet-ajax/editor/examples/default/defaultcs.aspx

1. Enable 'Real-Time HTML View' module,
2. highlight a word in the Design window,
3. delete the highlighted word
4. wait a second or two...
...the deleted word reappears.

If after step 3 I quickly click elsewhere in the design window, the deleted word does not reappear.

Can you provide a solution to this problem?

Thanks.

RadDataPager Align Right

Hello. I am trying to have my "displaying 1 of 10" element of the RadDataPager float all the way to the right. It doesn't seem proper to use hardcoded padding when the width of the page numbers can vary. Is there a good solution to this? Thanks! :-)

Code:

<LayoutTemplate>

<telerik: ID="RadDataPagerTop" runat="server" IsTotalItemCountFixed="True" Skin="Windows7" Width="752px" CssClass="Custom">

<Fields>

<telerik:RadDataPagerButtonField FieldType="FirstPrev" />

<telerik:RadDataPagerButtonField FieldType="Numeric" />

<telerik:RadDataPagerButtonField FieldType="NextLast" />

<telerik:RadDataPagerTemplatePageField>

<PagerTemplate>

<div style="float: right">

Displaying items

<asp:Label runat="server" ID="CurrentPageLabel" Text="<%# Container.Owner.StartRowIndex + 1 %>" />

to

<asp:Label runat="server" ID="TotalPagesLabel"

Text="<%# (Container.Owner.TotalRowCount < Container.Owner.StartRowIndex + Container.Owner.PageSize)?Container.Owner.TotalRowCount:Container.Owner.StartRowIndex + Container.Owner.PageSize  %>" />

of

<asp:Label runat="server" ID="TotalItemsLabel" Text="<%# Container.Owner.TotalRowCount %>" />

</div>

</PagerTemplate>

</telerik:RadDataPagerTemplatePageField>

</Fields>

</telerik:RadDataPager>

Can't get Demo Code to work

I copied the following code from the Splitter / External Content Demo Page
The Code works perfectly in IE9/IE10 standards mode on the Demo Page.
However, when I copy it to a test page on my site, the content never loads in IE9/IE10 Standards mode, and links only open in Popups.
I don't think the IFRAME is getting generated, in IE9/IE10 standards mode.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head><title>DEMO</title></head>

<body class="BODY">

<form id="Form1" method="post" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" />

<telerik:RadSplitter ID="RadSplitter1" runat="server" Height="400" Width="700">

<telerik:RadPane ID="RadPane1" runat="server" Width="150">Left Pane<br />

<telerik:RadPane ID="contentPane" runat="server" ContentUrl="http://blogs.telerik.com" />

</form>

</body>

Please help, this is driving me crazy, I don't understand how it works on the Demo page, but not on my test page...

Thanks!

Some can Preview; Others are Prompted to Save

I have a RadFileExplorer within my web page and at run-time, it displays any number of existing files and folders. Some of the file types that are displayed within the explorer are .gif, .jpg, .pdf, .png, .txt, .wmv, and more.

Users who browse to my website may experience 2 different types of behavior when they double-click on any one of the file types listed above (or when they right-click on a file and click Open). The first behavior (which is NOT the problem) that users experience when they double-click is that a radwindow will open, and display the file content. That’s the exact behavior that I want for all users to experience. In my case (I typically use IE 9), that is the default behavior that I always see. And what’s cool is that I really didn’t have to do any development work to make this happen; FileExplorer basically supports this behavior “out of the box”.

The second behavior (which IS the problem) that other users experience is that when they double-click on any one of the same exact files, they initially see the radwindow open, but it is always blank. What follows is a prompt by their browser to Save, Save As, or Cancel.

Initially I thought that the problem was a difference in browsers (IE vs. FireFox vs. Chrome, etc.). But then I discovered that some IE 9 users encountered the problem, while other IE 9 users did not.

Then I thought that maybe some client machines may not have Adobe Reader installed, or they may not have a graphical tool capable of rendering images, or something like that. But with every client machine that I investigated, they all had the necessary tools for supporting the file types listed above.

Is there some tweak that I can do with FileExplorer to ensure that the first behavior described above will always apply to every user? Is there something that I can add or modify within my web.config file?

Thank you,
Steven

RadToolTipManager Reponse Error

Hi,

I am using RadTooltipManager and getting this error. This works perfect when I hover my mouse two times on an image but when I try to hover it on third time it gives me the following error. Any help would be greatly appreciate.

Thanks

RadToolTipManager response error: Exception=Sys.WebForms.PageRequestManagerServerErrorException: Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page.
