Hi All,

I know that RadTicker can get data from XMLDataSource. But now I need to get data from database. Is RadTicker able to do this? In my case, I put RadTicker in RadRotator.   I got items for RadRotator dynamically from database, programming in the server side. So now how can RadTicker get items from database ?

Thank you !

Hello Y L,

In general you can use this approach in order to load the data in both controls:
<telerik:RadRotator ID="RadRotator1" DataSourceID="SqlDataSource1" runat="server"
    Width="200" ItemWidth="200" Height="100" ItemHeight="100">
    <ItemTemplate>
        <div>
            <div>
                <span>Product Name: '<%# Eval("ProductName")%>'</span> <span>Product ID: '<%# Eval("ProductName")%>'</span>
            </div>
            <telerik:RadTicker ID="RadTicker1" runat="server">
                <Items>
                    <telerik:RadTickerItem Text='<%# Eval("ProductName")%>' />
                </Items>
            </telerik:RadTicker>
        </div>
    </ItemTemplate>
</telerik:RadRotator>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="SELECT [ProductID], [ProductName] FROM [Alphabetical list of products]">
</asp:SqlDataSource>

Please note that you can load the data from server-side code by setting a collection to the RadRotator's DataSource property and calling its DataBind() method. The shown RadRotator and RadTicker's markup will work in this case as well.

Hi Fiko,

Thank you very much for your reply !

In my case, RadRotator got data from server side and I added RadTicker inside RadRotator, then I don't know how to program server side for RadTicker ..

Here is my code in aspx file:
 
 <telerik:RadRotator ID="rUpcomingEvents" runat="server" BorderWidth ="1px" BorderColor ="#3576b1"  FrameDuration ="1000" ScrollDuration ="1500" 
        Height ="280px" Width ="180px"   ScrollDirection ="Up"  > 
          <ItemTemplate > 
             <telerik:RadTicker ID="tickerEvents" runat="server" >             
              <Items > 
               <telerik:RadTickerItem  ID="Subject" >Test</telerik:RadTickerItem> 
              </Items> 
             </telerik:RadTicker> 
          </ItemTemplate> 
 </telerik:RadRotator> 



Here is my code in aspx.vb file, how I loaded data from server side for RadRotator:
Dim al As New ArrayList() 
rUpcomingEvents.ItemTemplate = New RadRotatorTemplate() 
rUpcomingEvents.DataSource = al 
rUpcomingEvents.DataBind() 
 
Public Class RadRotatorTemplate 
        Implements ITemplate 
  Public Sub New() 
  End Sub 
 
#Region "ITemplate Members" 
        Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn 
        Dim wrapper As New HtmlGenericControl("div") 
        AddHandler wrapper.DataBinding, AddressOf wrapper_DataBinding 
        container.Controls.Add(wrapper) 
        End Sub 
#End Region 
 
Sub wrapper_DataBinding(ByVal sender As Object, ByVal e As EventArgs) 
        Dim wrapper As HtmlGenericControl = TryCast(sender, HtmlGenericControl) 
        Dim item As RadRotatorItem = TryCast(wrapper.NamingContainer, RadRotatorItem) 
        wrapper.InnerHtml = String.Format(" {0} ", CType(item.DataItem, String)) 
End Sub 
End Class 

The RadRotator is working now, but I don't know how to load data dynamically for RadTicker.
Can you help me with this?

Thank you very much !

In my case, I  put RadTicker inside RadRotator  and I tried to load data for RadTicker like what you did:

<telerik:RadTicker ID="RadTicker1" runat="server">
                <Items>
                    <telerik:RadTickerItem Text='<%# Eval("ProductName")%>' />
                </Items>
            </telerik:RadTicker>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"
    SelectCommand="SELECT [ProductID], [ProductName] FROM [Alphabetical list of products]">
</asp:SqlDataSource>

It's not working. There's no ticker after I run it. I'm not sure if it's because my rotator got data dynamically from server side..

Hello Y L,

For your convenience I have attached a demo project. Could you please rework it in order to show the problem, open a new support ticket and send it back? I will check it on my side and do my best to provide a working solution as soon as possible.
