Hi!
I am trying to test RadComboBox in EnableLoadOnDemand="True" Mode.
Here is my code:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Test.aspx.cs" Inherits="Test" %> 
 
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> 
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 
<html xmlns="http://www.w3.org/1999/xhtml"
<head runat="server"
    <title></title
</head> 
<body> 
    <form id="form1" runat="server"
    <telerik:RadScriptManager ID="RadScriptManager1" runat="server"
    </telerik:RadScriptManager> 
    <div> 
                <telerik:RadComboBox ID="ActiveWebProjectCombo" runat="server" Width="350px"  
                    EnableLoadOnDemand="True" 
                    ItemsPerRequest="10" 
                ShowMoreResultsBox="True" EnableVirtualScrolling="True" onitemsrequested="ActiveWebProjectCombo_ItemsRequested"  
                    > 
                </telerik:RadComboBox> 
    </div> 
    </form> 
</body> 
</html> 

public partial class Test : System.Web.UI.Page 
    protected void Page_Load(object sender, EventArgs e) 
    { 
 
    } 
    protected void ActiveWebProjectCombo_ItemsRequested(object o, Telerik.Web.UI.RadComboBoxItemsRequestedEventArgs e) 
    { 
        WebProjectDataContext _dc = new WebProjectDataContext(); 
        int _count = (int)_dc.cms_WebProject_GetAvailableWebProjectsCount(_dc.UserId, _dc.WebProjectId, "%"); 
        int _itemsLoaded = e.NumberOfItems; 
        int _start = (int)Math.Truncate((double)(_itemsLoaded / 10)); 
        var _data = _dc.cms_WebProject_ListAvailableWebprojects(_dc.UserId, _dc.WebProjectId, "%"true, _start, 10); 
        if (e.NumberOfItems == 0) 
        { 
            ActiveWebProjectCombo.Items.Clear(); 
        } 
        foreach (cms_WebProject_ListAvailableWebprojectsResult _record in _data) 
        { 
            RadComboBoxItem _item = new RadComboBoxItem(_record.PROJECT_URL, _record.COMPONENT_ID.ToString()); 
            ActiveWebProjectCombo.Items.Add(_item); 
            _itemsLoaded++; 
        } 
        e.EndOfItems = _itemsLoaded >= _count; 
    } 

It seems code is working fine, except of hidden scrollbar. What I am doing wrong?
_dc.cms_WebProject_ListAvailableWebprojects(_dc.UserId, _dc.WebProjectId, "%"true, _start, 10) implements paged access to list of data which is showed in RadComboBox.

Hi Khourshed Yakubov,

You could resolve this by specifying either the Height or the MaxHeight property.
