Hello there

I am unable to render the tagcloud in a repeater; it generates the following exception:

Exception type: NullReferenceException

Exception message: Object reference not set to an instance of an object.

at Telerik.Web.UI.RadTagCloud.BindToEnumerableData

I have added some code below to replicate. In this example I have bound the repeater to a simple list.

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<script runat="server">

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

If Not IsPostBack Then

Dim oDatasource As New List(Of String)

oDatasource.Add("Item 1")

oDatasource.Add("Item 2")

oDatasource.Add("Item 3")

oDatasource.Add("Item 4")

rp.DataSource = oDatasource

rp.DataBind()

End If

End Sub

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:Repeater ID="rp" runat="server">

<ItemTemplate>

<telerik:RadTagCloud ID="RadTagCloud1" runat="server" Width="400px">

<Items>

<telerik:RadTagCloudItem Text="ASP.NET" Weight="12" />

<telerik:RadTagCloudItem Text="AJAX" Weight="134" />

</Items>

</telerik:RadTagCloud>

</ItemTemplate>

</asp:Repeater>

</div>

</form>

</body>
