<telerik:PanelBar ID="PanelBar1" runat="server" ExpandMode="SingleExpandedItem">
    <Items>
        <telerik:RadPanelItem runat="server" Text="Root1" ID="Root1">
            <Items>
                <telerik:RadPanelItem runat="server" Text="Child1OfRoot1"></telerik:RadPanelItem>
                <telerik:RadPanelItem runat="server" Text="Child2OfRoot1"></telerik:RadPanelItem>
                <telerik:RadPanelItem runat="server" Text="Child3OfRoot1"></telerik:RadPanelItem>
            </items>
        </telerik:RadPanelItem>
        <telerik:RadPanelItem runat="server" Text="Root2" ID="Root2">
            <Items>
                <telerik:RadPanelItem runat="server" Text="Child1OfRoot2"></telerik:RadPanelItem>
                <telerik:RadPanelItem runat="server" Text="Child2OfRoot2"></telerik:RadPanelItem>
                <telerik:RadPanelItem runat="server" Text="Child3OfRoot2"></telerik:RadPanelItem>
            </items>
        </telerik:RadPanelItem>
        <telerik:RadPanelItem runat="server" ID="Root3" Text="ExternalLink" NavigateUrl=http://www.google.com" Target="_blank">
        </telerik:RadPanelItem>
    </items>
</telerik:PanelBar>

Client Side Control Instantiation

I was wondering if it is possible to instantiate and instance of the RadEditor within the browser. We have a very client-centric AJAX application that doesn't rely on the web server to generate the html that will be rendered in the client. All the web server does is sends\retrieves raw data as well as serves up JS and XSLT files. It is within these XSLT files that the html is defined. Within some of these html layouts, we are using textarea tags to capture content and now would like to convert these to use a rich text editor. I was wondering if it is possible to use the RadEditor in this situation since the server would not be able to render the html for the declarative syntax.

Thanks in advance,
Eric

Databinding events not firing using ITemplate

I have a class implementing ITemplate for the rad rotator (inside a user control). The InstantiateIn method is called and all of the controls are created fine. However, the Databinding events in the implemented ITemplate class don't fire:

[code]

<

telerik:RadRotator ID="radRotateNews" runat="server"

Skin="Vista"

ScrollDuration="3000" FrameDuration="2000" RotatorType="FromCode"

Width="470px" Height="312px" CssClass="RadRotator_Default"

AppendDataBoundItems="true" >

</

telerik:RadRotator>

protected

void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

DataTable dt = GetScreens();

radRotateNews.DataSource = dt;

CreateNewsScreens(dt);

radRotateNews.DataBind();

}

protected

void CreateScreens(DataTable dt)

{

if (dt.Rows.Count > 0)

{

for (int i = 0; i < dt.Rows.Count; i++)

{

string screenType = dt.Rows[i]["ScreenTypeDesc"].ToString();
RadRotatorItem newsScreen = new RadRotatorItem();

newsScreen.ItemTemplate =

new NewsRotatorTemplate(screenType, dt.Rows.Count);

radRotateNews.Items.Add(newsScreen);

}

else

{

//show a default screen/image

}

public

class NewsRotatorTemplate : ITemplate

{

private string templateType;

private int numberScreens;

public NewsRotatorTemplate(string screenType, int noScreens)

{

//

// TODO: Add constructor logic here

//

this.templateType = screenType;

this.numberScreens = noScreens;
}

public void InstantiateIn(Control container)

{

....
Label

lblScreenNo = new Label();

lblScreenNo.ID =

"lblScreenNo" + screenNo;

lblScreenNo.DataBinding +=

new EventHandler(lblScreenNo_DataBinding);

container.Controls.Add(lblScreenNo);

....
}

void

lblScreenNo_DataBinding(object sender, EventArgs e)

{

Label lblScreenNo = (Label)sender;

RadRotatorItem container = (RadRotatorItem)lblScreenNo.NamingContainer;

string fieldValue = DataBinder.Eval(container.DataItem, "ScreenNo").ToString();

lblScreenNo.Text = fieldValue;

}

[/code]

Any ideas?

Toolbox in VS2008

Using the new Q1 2008 release of radControls for ASP.NET AJAX, I've installed the "standard" version of the Telerik.Web.UI.dll in the toolbox, and it's fine.

But I'd like to try the ASP.NET 3.5 version of radControls, especially radGrid, and the question is do I need to uninstall the toolbox items in VS2008, and reinstall using the dll in the Bin35 directory?

Thanks for any help, Steve
