RadTimePicker - Setting Style Client Side

I am attempting to use jQuery to set the background-color style of the RadTimePicker on the client side. While I can set this property using the BackColor attribute on the server side, setting it on the client side never results in visual changes... even though the code executes correctly.

I realize that the input text box in question has a ClientID that differs from the ClientID of the RadTimePicker control. It seems that it always follows the format MyTimePickerClientID_dateInput_text. So in order to change the background color, I do the following:

$(

"#" + <%= this.MyTimePickerControl.ClientID %> + "_dateInput_text").css("background-color", "#FF0000");

This jQuery code seems to run fine, and when I check the background-color in the debugger, it is indeed set to red. Yet there is no visual change in the browser window.

Is what I'm trying to do possible? If so, what am I doing wrong? I have tried this same technique with other style, such as border, but with the same lack of effect.

RadComboBox1_SelectedIndexChanged is not working for me.

RadScriptManager unable to load System.Windows

Hello,

In my web application, I have a master page with a RadScriptManager control. I'm getting the following error on page load:

Could not load file or assembly 'System.Windows,Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' orone of its dependencies. The system cannot find the file specified.

Based on the stack trace, the error appears to be thrown from the RadScriptManager constructor:

[FileNotFoundException: Could not load file or assembly 'System.Windows, Version=2.0.5.0, Culture=neutral,

PublicKeyToken=7cec85d7bea7798e' or one of its dependencies. The system cannot find the file specified.]

   System.Web.UI.ScriptManager.get_DefaultAjaxFrameworkAssembly() +388

   System.Web.UI.ScriptManager..ctor() +26

   Telerik.Web.UI.RadScriptManager..ctor() +14

The error only occurs the first time I load a page after a build of the application.  As soon as I refresh the page, the error goes away and the application functions as expect.

The error started occurring as soon as I added a Silverlight 3 application in my web app project.

Why are RadScriptManager and the .NET ScriptManager attempting to load a Silverlight dll?  Obviously, this dll is not in the bin directory of the web app.  Any ideas as to how I can make this error go away?

I'm using VS 2010, .NET 4.0, Silverlight 3, and Telerik RadControls for ASP.NET Ajax version 2010.1.415.40.

Thanks,

Andy

Treelist performance

I have inherited an application from a previous developer and I am having problems with the speed of the RadTreeList he has previously implemented.

The Treelist is a representation of a dealer hierarchy where the sub branches roll up to a principal dealer within a country.

Eg Principal Dealer 11020000

Has branches: 11020001, 11020002, 11020003

For each row we are displaying name and address information as well as image buttons that allow a dealer to be selected/assigned to a role holder or for all dealers for a principal to be selected at principal level.

This is using the NeedDataSource event.

Now I am caching data from my SQL Server 2008 datasource wherever I can but I am finding that expanding nodes at principal level and performing updates is painfully slow. Even at it’s largest for a single country the treelist only has around 2000 records and the round trips to the server to get data and perform updates look pretty quick.

I have been through all of the performance tips on the site but nothing seems to be improving it i.e. RadCompression etc.

Can you suggest anything that might be available to improve performance?

Menu Item Parent Child Relationship not working

Hi,

I'm using Telerik RadControls Q1 2008. I have a Rad Menu on the masterpage of my application and i'm trying to bind it to a linq datacontext.

The binding works fine but my problem is That Child Items are always displayed as root items.

I have checked that ParentId of all roots items is NULL and of all the child items is that of the assigned parent.

Below is the code :

Private Sub LoadMenuItems()

Dim MenuDC As New MenuItemDataContext

RadMenu1.DataSource = MenuDC.usp_TABLE_MENU_ITEM_Select().ToList()

RadMenu1.DataBind()

End Sub

<telerik:RadMenu ID="RadMenu1" runat="server" Skin="Office2007" DataFieldID="MENU_ITEM_ID"

DataFieldParentID="PARENT_ID" DataNavigateUrlField="PAGE_URL" DataTextField="MENU_ITEM_NAME"

DataValueField="MENU_ITEM_ID">

<DefaultGroupSettings ExpandDirection="Down" />

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</telerik:RadMenu>

I do not know what i'm missing here.

Shared Calender with RadAjaxManager Fails after Postback

Hi,

I've had this problem for a while and have not found a solution. When using a Shared Calender with the RadAjaxManager, the pop-up only works the 1st time. Here is the simplest implementation of the example.

rdp.SharedCalendar = RadCalendar1;

rdp.AutoPostBack = true;

rdp.ID = "rdp" + i.ToString();

rdp.SelectedDateChanged += new Telerik.Web.UI.Calendar.SelectedDateChangedEventHandler(rdp_SelectedDateChanged);

}

void rdp_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)
