<telerik:RadComboBox ID="radComboCustomer" Skin="Sunset" runat="server" Width="50%"
     CssClass="ComboBox" OnClientSelectedIndexChanged="setSelectedCustomerData" EnableLoadOnDemand="true"
   OnItemsRequested="radComboCustomer_ItemsRequested" ShowMoreResultsBox="true"
      EnableVirtualScrolling="true"></telerik:RadComboBox>


 protected void radComboCustomer_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e)
    {
        MIDAS.DAL.CompanyFactory objCustomerFactory = new MIDAS.DAL.CompanyFactory(SessionScope.FactoryScope);

        CompanyCollection allCustomer = new CompanyCollection();
        ICriteria criteria = objCustomerFactory.GetBasicCriteria();
        List<ICriterion> filters = new List<ICriterion>();
       

        if (!string.IsNullOrEmpty(e.Text))
        {
            filters.Add(Restrictions.Like("CompanyName", e.Text, MatchMode.Start));
        }

        
        foreach (ICriterion filter in filters)
        {
            criteria.Add(filter);
        }

        allCustomer = objCustomerFactory.GetAll(criteria, "CompanyName ASC");


        int itemOffset = e.NumberOfItems;
        int endOffset = Math.Min(itemOffset + 10, allCustomer.Count);
        e.EndOfItems = endOffset == allCustomer.Count;

        for (int i = itemOffset; i < endOffset; i++)
        {            
            radComboCustomer.Items.Add(new RadComboBoxItem(allCustomer[i].CompanyName.ToString()  ,                              
            allCustomer[i].CompanyId.ToString()));
        }

        e.Message = GetStatusMessage(endOffset, allCustomer.Count);
    }

 private static string GetStatusMessage(int offset, int total)
    {
        if (total <= 0)
            return "No matches";

        return String.Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>", offset, total);
    }


When match mode is with MatchMode.Start then records are displyaing with search and all but when MatchMode.Anywhere
which is property of Nhibernate then records are coming from db and are assigning to Radcombo by RadComboBoxItem
property but i cant see the records in combo.But i can see count properly.
But it works fine with MatchMode.Start

Hi John,

You are adding the Items to the RadComboBox manually, so please make sure that when MatchMode is Anywhere the following loop actually runs and adds Items:
for (int i = itemOffset; i < endOffset; i++)
{           
    radComboCustomer.Items.Add(new RadComboBoxItem(allCustomer[i].CompanyName.ToString()  ,                             
    allCustomer[i].CompanyId.ToString()));
}

I hope this helps.

for (int i = itemOffset; i < endOffset; i++)
{           
    radComboCustomer.Items.Add(newRadComboBoxItem(allCustomer[i].CompanyName.ToString()  ,                             
    allCustomer[i].CompanyId.ToString()));
}

Oh its basic loop i had putted break point and finally before ending of the funciton ths combo shows all items in 
his list when i am watching in QuickWatch window in debugger mode.
 
While entering cursor in combo it is displyed as open combo with all records
so when typing a letter records bind to combo are not visible to users but
when onblur it automatically closes the empty  record combo and when again focuing on
combo now its showing the searched records.So i think records are present but not visible but
on close and open it shows all records.

please provide me approprite solution.

Just check in codebehind of page if you  have mentioned the below code..
        radCombCustomerName.Filter = Telerik.Web.UI.RadComboBoxFilter.StartsWith;

replace above code with 

 radCombCustomerName.Filter = Telerik.Web.UI.RadComboBoxFilter.Contains ;

       Now its working

Hello John,

So this means that the Filter did not match the MatchMode property, i.e. Items were returned based on a 'contains' filter however, the RadComboBox filtered them on the client with a 'starts with' filter. Is this correct?

Does setting the Filter property of the RCB to 'Contains' fix the issue?

Best wishes,
Simon
