Show only the days of the current month in MonthView

Hey guys,
After looking thru the forums I can't seem to find anything to help me. I am wondering if it is possible to only show the actual month in the MonthView and NOT show the last/next few days of the previous/next month? I have two RadSchedule control on a page to give a 2 month view but the week of the next month is distracting to see twice ( example of month overlap ) Is there an easy way I can suppress the extra days?
Thanks,
Bryan Smouse

Problems with using CustomValidator for client-side validation

Hello, I'm trying to implement custom validation for my web page, but having problem. I want my ComboBox to be populated asynchronously from Web Service. So, here's the code of my page:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="CBSamplePage.aspx.cs" Inherits="CBSamplePage" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

<head runat="server">

<title>

RadComboBox Sample Page

</title>

</head>

<body>

<form id="form1" runat="server">

<script type="text/javascript">

function validatePerson(source, args) {

if ($find("<%=cbPersons.ClientID %>").get_value() > 0) {

args.IsValid = true;

} else {

args.IsValid = false;

}

</script>

<div>

<asp:ScriptManager runat="server" ID="scriptManager1"></asp:ScriptManager>

<table>

<tr>

<td>

<asp:Label runat="server" ID="lbl1">Select something</asp:Label>

</td>

<td>

<telerik:RadComboBox EmptyMessage="Select a person..." runat="server" ID="cbPersons" AllowCustomText="true" EnableLoadOnDemand="true">

<WebServiceSettings Method="GetPersons" Path="~/SampleWebService.asmx" />

</telerik:RadComboBox>

<asp:CustomValidator runat="server" ID="customValrPerson" ValidationGroup="Sample" ControlToValidate="cbPersons" ErrorMessage="Required" ClientValidationFunction="validatePerson"></asp:CustomValidator>

</td>

</tr>

<tr>

<td colspan="2">

<asp:LinkButton runat="server" ID="lnkSubmit" ValidationGroup="Sample" CausesValidation="true">Submit</asp:LinkButton>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

And here's the code of the web service that I use for generating ComboBox items:

<%@ WebService Language="C#" Class="SampleWebService" %>

using System;

using System.Web;

using System.Web.Services;

using System.Web.Services.Protocols;

using System.Web.Script.Services;

using Telerik.Web.UI;

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[ScriptService]

public class SampleWebService : System.Web.Services.WebService {

static string[] persons = { "Person Number 1", "Person Number 2", "Person Number 3", "Person Number 4", "Person Number 5" };

[WebMethod]

public RadComboBoxItemData[] GetPersons(RadComboBoxContext context)

{

RadComboBoxItemData[] result = null;

result = new RadComboBoxItemData[persons.Length];

for (int i = 0; i < persons.Length; i++)

{

result[i] = new RadComboBoxItemData { Text = persons[i], Value = i.ToString() };

}

return result;

}

So, I have number of problems.

1) When I load the page and click "Submit" link, validation doesn't happen and page gets post back. Obviously, that's wrong because ComboBox doesn't have any item selected.
2) When I select an item I see "Required" text. That happens because when validation function is called, this code:

$find("<%=cbPersons.ClientID %>").get_value()

returns "undefined". Sure, that's not how I expect things to work. When I click "Submit" link everything works properly.

P.S. It can seem that I would use RequiredFieldValidator in this example, but sometimes I will need to change the way selection is validated, so I would prefer to use CustomValidator for this.

"'null' is null or not an object" error in IE8 but works in FF & Chrome

I'm getting this error in IE8 only on my RadAjaxManager. Works great in Chrome & FF4.

Webpage error details

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; GTB6.6; SLCC2; 

.NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; 

BRI/2)

Timestamp: Tue, 29 Mar 2011 22:25:34 UTC

Message: 'null' is null or not an object

Line: 162

Char: 13

Code: 0

Here's the RadAjaxManager:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="PageLoaded">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="Label1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Here's the OnAjaxRequest & OnLoad methods:

protected override void OnLoad(EventArgs e)

{

base.OnLoad(e);

RadAjaxManager ajaxManager = RadAjaxManager.GetCurrent(this.Page);

if (ajaxManager == null)

{

ajaxManager = new RadAjaxManager();

ajaxManager.ID = "RadAjaxManager1";

Controls.Add(ajaxManager);

this.Page.Items.Add(typeof(RadAjaxManager), ajaxManager);

}

protected void PageLoaded(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

if(e.Argument=="DocumentReady")

DisplayDates(new DateTime(radCal.FocusedDate.Year, radCal.FocusedDate.Month, 1), new

DateTime(radCal.FocusedDate.Year, radCal.FocusedDate.Month, DateTime.DaysInMonth(radCal.FocusedDate.Year, radCal.FocusedDate.Month)));

}

Here's the javascript:

$(document).ready(function () {

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

ajaxManager.ajaxRequest("DocumentReady");//THIS IS WHERE THE ERROR OCCURS

}

I have a feeling that I'm missing something important, but I'm still pretty new to telerik. Any help would be appreciated, thanks.

Add some padding to Level 1 Items

I'm just trying to add some top and bottom padding to Level 1 items (the first level below the root level). I've got a custom default.css class which I copied out of the install folder.

I've been at it for about 2 hours, with no luck. For some reason, this is really difficult, probably because I'm not a CSS guy.

Scheduler display values

Hi,

I am working on Scheduler.

I have an issue:

There are many people using my scheduler and they setup their appointment with this scheduler. Whoever logs in will have their details like first name and last name entered and is stored in the database tables.
Now, after logging in when they double click on the scheduler to setup an appointment, I want their first name and last name to be displayed on the scheduler overriding of what they want to save. Their first name and last name will be pulled from the database and should be displayed in the scheduler.
How do I do this? Is there any way?

Hide Expand nestedviewtemplate

<telerik:RadGrid ID="rgStatus" runat="server" AutoGenerateColumns="False" BorderStyle="None" Width="100%">

<HeaderStyle HorizontalAlign="Left" Font-Bold="true" BorderWidth="0" BorderStyle="None" />

<ItemStyle BorderStyle="None" BorderWidth="0" />

<ClientSettings EnablePostBackOnRowClick="false"></ClientSettings>

<MasterTableView>

<telerik:GridTemplateColumn ItemStyle-Width="250" DataField="StsExternalDesc" UniqueName="StsExternalName" HeaderText="Status">

<ItemTemplate>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn ItemStyle-Width="125" DataField="StsDateTime" HeaderText="Date" />

<telerik:GridBoundColumn ItemStyle-Width="99" DataField="StsDateTime" HeaderText="Time" />

</Columns>

<NestedViewTemplate>

<table border="0" cellpadding="2" cellspacing="0">

<tr id="trStsDesc1">

<td><asp:Label ID="lblStsDesc1" runat="server" Text='<%# Eval("StsDesc1") %>'></asp:Label></td>

</tr>

<tr id="trStsDesc2">

<td><asp:Label ID="lblStsDesc2" runat="server" Text='<%# Eval("StsDesc2") %>'></asp:Label></td>

</tr>

</table>

</NestedViewTemplate>

</MasterTableView>

</telerik:RadGrid>

I see alot of articles on this subject but I am still not able to get it to work. I have a gridview with 3 columns status,date,time.
For each status there could be some notes associated with it, which if there are notes then show in the nestedtemplate.My issue is if there are no notes I don't want to see the image to expand. If there is a note for a particular status then show the image to expand.Right now my code shows the expand image even if the notes are blank.

for example on the calendar should be like

(Joe Smith) Vacation

right now it only shows Vacation with a unique assigned color, but it would be great if it could also display the person name on the calendar.

Thanks,

Client side OnCommand page number issue

Hi,

I recently attached a javascript event handler the client event OnCommand. I noticed that when I select a page using the numeric pager, the command argument for the event is the page number. For instance, I select page 1, the command name is 'Page' and the command argument is 1. When I select page 1 using the master table view set_currentPageIndex, I get the command name 'Page', but the command argument is 0, the index value I passed to the function. This has caused me some difficulty as I don't necessarily have a way of determining how the event was originally triggered.

Obviously it would be preferable if it used either the page number or the index, but not both.

I am currently on 2010 Q2.

Thanks,
Joe
