Your XAML seems OK . Things should be working with this setup . Can you please paste me the c# implementation of the objects you use to feed RadGridView and the combo box with data..
This will be in help to reproduce the issue and find the cause.

Thank you for your reply.I have attached the c# class which i have been using to bind RadComboBox.
using System;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.Collections.ObjectModel;
using System.ComponentModel;
namespace IVRSDesigner
{
public class PromptsComboSource
{
public static ObservableCollection<DataReference.Prompts> PromptsForStep
{
get
{
return _promptsForStep;
}
set
{
_promptsForStep = value;
}
}
private static ObservableCollection<DataReference.Prompts> _promptsForStep = new ObservableCollection<DataReference.Prompts>();
}
}
void ServiceRef_GetAllPromptsCodeTextCompleted(object sender, DataReference.GetAllPromptsCodeTextCompletedEventArgs e)
{
try
{
PromptsComboSource.PromptsForStep = e.Result;
}
catch (Exception ex)
{
MessageBox.Show(ExceptionResources.ExceptionLoadingPromptCodeText + ErrorResources.RefreshMessage);
ExceptionLogger.LogException(ex);
}
}
I was talking about the business objects ( e.g. the DataReference.Prompts) so I could build a repro project here.
Nevermind,
I think I have figured out the issue :
Please try the following settings for the combobox :
IsTextSearchEnabled="True"
TextSearchMode="Contains"
IsDropDownOpen="True"
IsEditable="True"
Please note that in TextSearchMode contains , RadComboBox will not autocomplete the text, it would only highlight the item found in the dropdown .
Best wishes,

I have implemented Custom Filtering solution, (Filtering on multiple Paths - ID + DESC)
the issue I run into is the selected item does not get set properly with case insensitive
I created a custom control inheriting from RadComboBox and then I have set these values in the constructor:
public RadComboBoxCustomFilter()
{
// this should allow for case insensitive (type joe and I should be able to select JOE)
// ** JOE is NOT SELECTED because it did not match "joe" exactly - will automatically select the FIRST filtered item in list.
// ** JOEL - IS Selected if Clicked or Press Enter over item
TextSearchMode = TextSearchMode.Contains; //
case insensitive setting
IsTextSearchEnabled = true;
IsEditable = true; // allow text to be entered into the textbox to seach
OpenDropDownOnFocus = true;
StaysOpenOnEdit = true;
IsFilteringEnabled = true; // makes the filtering possible
UpdateTextOnLostFocus = true;
TextSearch.SetTextPath(this, "ID"); //after item is selected this is the display. If not set it does not know how to display because I use a custom Item Template { ID + DESC }
FilteringBehavior = new RadComboBoxCustomFilterBehavior();
}
Please let me know if you need additional information to reproduce this issue.
