Hi! I have a problem with rendering in RadWizardStep. I create step programmatically.During this creation i insert UserControl wich contains RadTreeView

control. Everything is fine until i expand nodes of TreeView. There is no scrollbars and a bottom part of nodes becomes invisible.

I've read the topic http://www.telerik.com/forums/height-attribute-of-radwizard, but this not works. Any suggestions to fix this issue?

Here's my code:

User Control

 

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TreeControl.ascx.cs" Inherits="Wizard.TreeControl" %>

I've fixed it, just added to UserControl css class

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="TreeControl.ascx.cs" Inherits="Wizard.TreeControl" %>
 
<style type="text/css">
    .search {
        width:inherit;
        height:inherit;
        overflow:auto !important;
    }
  
</style>
 <div class="search">
      
        <telerik:RadTextBox ClientEvents-OnLoad="clientLoad" ID="RadTextBoxFilter1" runat="server" />
        <telerik:RadTreeView ID="RadTreeViewFilter1" runat="server">.......
