Is there a SelectionBoxTemplate for the RadGridView GridViewComboBoxColumn? I saw a template that was posted in the forum area from a while ago, but when I tried it in one of the latest Telerik libraries, it doesn't work?

 


 <telerik:GridViewComboBoxColumn Header="Sic Code"
                                                    IsComboBoxEditable="true"
                                                    DataMemberBinding = "{Binding SicCodeID}"
                                                    ItemsSource="{Binding Current.SicCodes, Source={StaticResource Lookups}}"
                                                    DisplayMemberPath="SicCodeValue"
                                                    SelectedValueMemberPath="SicCodeID"  
                                                    EditTriggers="CellClick"
                                                    LostFocus="GridViewComboBoxColumn_LostFocus"
                                                    TextSearch.TextPath="SicCodeValue"
                                                    Width="226">
                            <telerik:GridViewComboBoxColumn.EditorStyle>
                            <Style TargetType="telerik:RadComboBox">
                                <Setter Property="ClearSelectionButtonVisibility" Value="Visible" />
                                <Setter Property="ClearSelectionButtonContent" Value="Clear" />
                                <Setter Property="Foreground" Value ="Black" />
                                <Setter Property="DropDownWidth" Value ="480" />
                                <Setter Property="OpenDropDownOnFocus" Value="True"/>
                                <Setter Property="SelectionBoxTemplate">
                                    <Setter.Value>
                                        <DataTemplate >
                                            <StackPanel Orientation="Horizontal" HorizontalAlignment="Left" >
                                                <TextBlock Text="{Binding SicCodeValue}" Width="70" />
                                                <TextBlock Text="{Binding SicCodeDescription}" Width="370"/>
                                            </StackPanel>
                                        </DataTemplate>
                                    </Setter.Value>
                                </Setter>
                                <Setter Property="ItemTemplate">
                                    <Setter.Value>
                                        <DataTemplate >
                                            <StackPanel Orientation="Horizontal" HorizontalAlignment="Left" >
                                                <TextBlock Text="{Binding SicCodeValue}" Width="70" />
                                            </StackPanel>
                                        </DataTemplate>
                                    </Setter.Value>
                                </Setter>
                            </Style>
                        </telerik:GridViewComboBoxColumn.EditorStyle>

Hello Pavel,

With the current implementation of the underlying RadComboBox control, used in the GridViewComboBoxColumn, applying a custom SelectionBoxTemplate will only be available when the IsComboBoxEditable property's value is set to False. However, if you want to customize the input area of an editable RadComboBox control, you should use the TextBoxStyle property. The Selection Box Template article in our documentation provides additional information on this topic.

I hope the provided information is of help to you.
