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();

ComboBox in SharePoint 2010 - Callback error

I am using a RadComboBox control in a SharePoint 2010 visual web part with Load-On-Demand enabled (server-side ItemsRequested event), but I am getting a client error "There was an error in the callback" when I set focus to the combobox or if I type a letter in the textbox. With debugging enabled I can see the user control's Page_Load event being fired, but the ItemsRequested event is never fired. Any ideas as to why this is happening?

Thanks,
Larkin

Setting Height Dynamically for Bar and Line Chart with Grid

Hi:
I am creating a chart, where the chart could be a line or bar. The # of point could be 3 or 120. So the following issue and example are interestingly similar, I am looking to remove the white-space above and below the plot-area.
http://www.telerik.com/community/forums/aspnet-ajax/chart/white-space-above-and-below-chart-when-dynamically-setting-height.aspx
But, I have a RadGrid below my chart. The fun part is that the 2 controls seem to partially overlay each other (not good in a production system).

<%@ Page Title="" Language="VB" MasterPageFile="~/Member.Master" AutoEventWireup="false" CodeFile="RadChartTitle.aspx.vb" Inherits="Learning_RadChartTitle" %>

Visual Studio Extensions for RadControls for ASP.NET AJAX

I initially downloaded the trial version and installed it. I then downloaded my licensed version. The extensions don't appear to be correctly installed in VS 2010. Although I have the telerik menu, I don't have anything under it except "About". Further the templates are not present and the context menu of the solution explorer is not present.

I have uninstalled and installed 3 times with no change.

Is there a manual way to install?

Thanks,

Installer and VS Extensions

How to filter on multiple values in a custom filter (Combobox with Checkboxes)

Hello,
I need to have a grid with Custom Filters. Those filters needs to be comboboxes with checkboxes.
I started from http://demos.telerik.com/aspnet-ajax/grid/examples/programming/filteringtemplatecolumns/defaultcs.aspx.
I can successfully run the sample & I modified the combobox (checkboxes=true) to display all items with checkboxes.
Now I've 2 issues :
1°) When I filter on 1 checkbox from the combobox "Country", it works. But when I check 2 checkboxes (2 countries), I can not have results.
Do you have another sample or a doc explaining how to handle multiple selections for 1 filter ? Or any tips to explain how to do that ?
2°) The custom filters column are not sortable, how to have them sortable too ?
