Pratik,

The WPF ComboBox has a SelectionBoxItemTemplate property you'd want to set too. Its ItemTemplate is only used in the dropdown.

Hi,
While trying with following xaml code


<ComboBox x:Name="toolWindowsListBox" Margin="0,3,0,0" Height="150" ItemsSource="{Binding ElementName=dockSite, Path=ToolWindows}" SelectedIndex="1">
                            <ComboBox.ItemTemplate>
                                <DataTemplate DataType="docking:ToolWindow">
                                    <TextBlock x:Name="title" Text="{Binding Title}" />
                                </DataTemplate>
                            </ComboBox.ItemTemplate>
                            <ComboBox.SelectionBoxItemTemplate>
                                <DataTemplate DataType="docking:ToolWindow">
                                    <TextBlock x:Name="title" Text="{Binding Title}" />
                                </DataTemplate>
                            </ComboBox.SelectionBoxItemTemplate>
                        </ComboBox>

it gives following error message it states that you can't set this property

Error 1 The property 'ComboBox.SelectionBoxItemTemplate' cannot be set because it does not have an accessible set accessor. Line 67 Position 30.
xaml 67 30 SampleApplication-CSharp.VS2008

please help me in this thing.

thanx in advance

Pratik,

Whoops, sorry you are right. Now I remember, this was a bad design by Microsoft not making it easily customizable. There are several posts like this with a workaround though:
