  I have a RadBinaryImage in a asp:Repeater template. I also have a RadBinaryImage in a RadRotator template. The Repeater works. The Rotator does not. What am I doing wrong?

  <asp:Repeater runat="server" ID="AttachmentRepeater" EnableViewState="false">

      <ItemTemplate>

          <telerik:RadBinaryImage ID="RadBinaryImage1" runat="server" ResizeMode="Fit" DataValue='<%# Eval("Image")%>' Width="200" Height="200" />

      </ItemTemplate>

  </asp:Repeater>

   

          <telerik:RadRotator ID="thumbRotator" runat="server" RotatorType="ButtonsOver" Width="572"

              Height="118px" ItemHeight="118" ItemWidth="145" FrameDuration="1000" ScrollDirection="Left,Right" OnItemClick="ShowImage">

              <ItemTemplate>

                  <div>

                      <telerik:RadBinaryImage ID="RadBinaryImage2" runat="server" ResizeMode="Fit"

                                               DataValue='<%# Eval("Image")%>' Width="200" Height="200" />

                  </div>

              </ItemTemplate>

              <ControlButtons LeftButtonID="img_left" RightButtonID="img_right" />

          </telerik:RadRotator>

  
  In the following code, the Images collection contains objects that have a Byte[] property and a String property. The Byte[] is the contents of an image acquired by using an AsyncUpload control.
  
  

  DataTable rotatorData = new DataTable();

   rotatorData.Columns.Add("Image", typeof(System.Array));

   rotatorData.Columns.Add("Name");

   foreach (ImageInfo tempInfo in Images)

   {

       DataRow row = rotatorData.NewRow();

       row["Image"] = tempInfo.Image;

       row["Name"] = tempInfo.Name;

       rotatorData.Rows.Add(row);

   }

   thumbRotator.DataSource = rotatorData;

   thumbRotator.DataBind();

  Hello David,
  
  I have tried the same scenario and that worked as expected. Please make sure that you have registered the http handler of the RadBinaryImage control as explained here.
  aspx:
  

  <telerik:RadRotator ID="RadRotator1" runat="server" Width="305px" Height="114px" ScrollDuration="500" FrameDuration="2000" ItemHeight="110" ItemWidth="100" DataSourceID="SqlDataSource1">

           <ItemTemplate>

                <telerik:RadBinaryImage runat="server"  ID="RadBinaryImage1" DataValue='<%#Bind("Picture") %>'

                    AutoAdjustImageControlSize="false" Width="90px" Height="110px" AlternateText="No Image!!" />

              </ItemTemplate>

  </telerik:RadRotator>

  
  Thanks,
  Shinu.
