So i would like to have the newsrotator to use pages, instead of news. I think i have the general idea here but I think i may have something incorrect in the fluent api. I end up getting

Must specify valid information for parsing in the string.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.ArgumentException: Must specify valid information for parsing in the string.

Source Error:

so in the page load for the rotator i set the rotators data source to use pages that are published

RadRotator1.DataSource =

App.WorkWith()

.Pages()

.Where(n => n.Page.Status == ContentLifecycleStatus.Live)

.Get()

.Take(this.NewsLimit)

.ToList()

.Join(App.WorkWith()

.Images()

.Get()

.Where(i => i.Parent.Title == albumName.ToString() && i.Status == ContentLifecycleStatus.Live),

item => item.Title.Value,

image => image.Title.Value,

(item, image) => new { NewsItem = item, NewsImage = image });

Then under data binding i use page instead of news item

Page newsItem =

(Page)TypeDescriptor

.GetProperties(e.Item.DataItem)["Page"]

.GetValue(e.Item.DataItem);

Since pages has a description and not a summary I would like to use that

if (text != null) text.Text = newsItem.Description;

The target NewsPage uses typeof(NewsView), is there some sort of PageView?

as well as under the rotator when intialize controls i use Pages for the rotators datasource

this.RadRotator1.DataSource = App.WorkWith().Pages().Where(p => p.Page.Status == ContentLifecycleStatus.Live).Get().Take(this.NewsLimit).ToList().Join(

App.WorkWith().Images().Get().Where(i => i.Parent.Title == albumName && i.Status == ContentLifecycleStatus.Live),

item => item.Title.Value,

image => image.Title.Value,

(item, image) => new { NewsItem = item, NewsImage = image });

Horizontal RadMenu all the way and full width of dropp down

I want to make the following changes to the RadMenu apperence:

* I want the menu to be 100% width of <div id="top-menu-wrapper"> that the control is placed inside
* I want the dropp down submenu to be full width of <div id="top-menu-wrapper"> (same as above) and flow horizontally. Flexible amount of columns depending on number of sub-menu-items and length of items i.e. wrapping menu items.
* How to be able to add the shaddow images to top of submenu, but the shaddow should not go over the selected menu item

Basically it should behave similar to this website: www.nrk.no

I have attached a picture of the end result that I am trying to archieve with the RadMenu. Menu items is built dynamically through code. And I need to archieve this with CSS. this possible with the RadMenu and how can I arhieve this?

Many thanks
Lisa-Marie

Various questions on Timelineview, date header and working days display

Hi,

I'm interested in using the Timelineview of the RadScheduler control in a project I'm working on to allocate tasks to resources, and have a few questions. I need to display the Timelineview over multiple days (1-14 days, selectable setting) at 30m intervals. For an indication of what i'm trying to replicate using RadScheduler, please see the attached screenshot.

1. I need to display a header with the date and subheader for each hour. The ColumnHeader is fine for 1 day display, but for multiple days display it is quite useless. I need the date to be visible above the hours as i scroll horizontally to the next day, if not, the user does not know which day the hours are when multiple days are displayed.
2. The working day is from 0800-1900. I need the Timelineview to end at 1900 and next column is then 0800 the next day. Is this possible?
3. I need to set a hard line at the end of the day, i.e. change the style of the vertical bar at the end of 1900 to visually indicate a new day starts. How can this be done?
4. I need to set a moving time line across all resources, which is updated every 1 minutes, to display current time on a day. Is there a possibility to visually indicate in the timelineview what the current time is? (see red line in attached screenshot)

Thanks.

Loading Panel not loading

I have a situation like this:

I have my base page object.

Inside of my base page I have an ajax Manager.
Inside of base page I have a user control
Inside of this user control I have another user control with a radajaxmanagerproxy
Inside of this user control I have a RadGrid
For my edit form settings I have using EditFormType="WebUserControl"
Inside of that control I have a radajaxmanagerproxy

This radajaxmanagerproxy will not show the loading panel when an ajax postback occurs.

The page other then this works great, but for some reason the loading panel will not show.

Also during some release possibly the 2008 Q2 this worked perfectly. I believe after upgrading to 2008 Q3 it stopped, and we never noticed.

Do you have any guidelines for nesting radajaxmanager(proxy) like this in order to get my desired outcome?
Are there any debugging points that you can suggest?

We are now on 2008 Q3. We have not upgraded to 2009 Q1 yet.

RadWindow cannot be found in UpdatePanel

Hi

I have a page on which is a complex multi tabbed form that I want to appear when the user clicks a link on the main page.

Simple stuff. This I had working with the form appearing in a div that was hidden and simply made visible. However, having bought the Rad controls for ASP.NET I wanted the use the very attractive RadWindow to hold the form. It is there the problems began.

The entire form is in an update panel as it needs to be for many reasons not relevant to this issue.

The top of the form looks like this.

<asp:UpdatePanel runat="server" id="UpdatePanel1" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadWindowManager ID="rwManager" Behaviors="Close,Move, Resize" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="true" runat="server" Skin="Outlook" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="rwAdvancedSearchForm" Modal="true" runat="server" Width="700" Height="600">

<ContentTemplate>

<table class="dv" cellpadding="0" cellspacing="0" border="0">

and so no.

You can see in there the first (and only) RadWindow in this RadWindowManager is called rwAdvancedSearchForm.

Back on the page I have a link that calls this javascript function.

function showAdvancedSearchForm(){

var win = $find("<%#rwAdvancedSearchForm.ClientID %>");

win.show();

win.center();

}

... where ASP.NET is putting the name of the control into the page.

The problem is that the javascript breaks on the line 'win.show() as 'win' is not found.

Looking at the source code I can see that asp.net has put the correct name into the page. Here is a bunch of code from the source that has the js function above and the div at the bottom that is rsAdvancedSearchForm. You can see the names are correct.

function showAdvancedSearchForm(){

var win = $find("ctl00_PageContent_rwAdvancedSearchForm");

win.show();

win.center();

}

</script>

<div id="ctl00_PageContent_UpdatePanel1">

<div id="ctl00_PageContent_rwManager" style="display:none;">

<div id="ctl00_PageContent_rwAdvancedSearchForm" style="display:none;">

Despite this the javascript cannot 'show()' the div has it cannot be found.

What's going on?
