Hi,
I've a RadComboBox inside the RadGridView. When loading the tab very first time data inside the combobox is not displaying.

We have data in selectedvalue and in itemsource collection, but it is not displaying. Combobox is in editable mode.
<telerik:RadComboBox x:Name="ComboBox" Tag="{Binding SeqNo,UpdateSourceTrigger=PropertyChanged}" Style="{StaticResource TextSearchStyle}" 
           ItemsSource="{Binding DataContext.List, Mode=TwoWay, RelativeSource={RelativeSource AncestorType={x:Type UserControl}, Mode=FindAncestor}}"
                SelectedValue="{Binding Code, Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" SelectedValuePath="Code"  IsEditable="True" ItemTemplate="{StaticResource ComboBoxItem}" ItemContainerStyle="{StaticResource ComboBoxItemStyle}"
                CanKeyboardNavigationSelectItems="True" TextSearchMode="Contains" IsFilteringEnabled="True"  OpenDropDownOnFocus="False" GotFocus="ComboBox_GotFocus" LostFocus="ComboBox_LostFocus" DropDownClosed="ComboBox_DropDownClosed"  GotKeyboardFocus="ComboBox_GotKeyboardFocus"
                IsTextSearchEnabled="True" KeyDown="ComboBox_KeyDown" PreviewKeyDown="ComboBox_KeyUp" CanAutocompleteSelectItems="False" TabIndex="7" >
                                                    <telerik:RadComboBox.ToolTip>
                                                        <StackPanel Height="Auto" Width="Auto" MaxWidth="300" Background="#F2F2F2">
                                                            <TextBlock Text="{Binding ShortDescription}" Style="{StaticResource ToolTipCodesDescriptionTextBlock}"/>
                                                        </StackPanel>
                                                    </telerik:RadComboBox.ToolTip>
                                                    <i:Interaction.Triggers>
                                                        <i:EventTrigger EventName="GotFocus">
                                                            <i:InvokeCommandAction Command="{Binding DataContext.LoadPopUpCommand, RelativeSource={RelativeSource AncestorType={x:Type UserControl}, Mode=FindAncestor}}" CommandParameter="{Binding DataContext, ElementName=ComboBox}" />
                                                        </i:EventTrigger>
                                                        <i:EventTrigger EventName="DropDownClosed">

                CommandParameter="{Binding DataContext, ElementName=CPTComboBox}"/>
                                                        </i:EventTrigger>
                                                        <i:EventTrigger EventName="LostFocus">
                                                            <i:InvokeCommandAction Command="{Binding DataContext.ComboLostFocusCommand, RelativeSource={RelativeSource AncestorType={x:Type UserControl}, Mode=FindAncestor}}" CommandParameter="{Binding DataContext, ElementName=ComboBox}" />
                                                        </i:EventTrigger>
