Keep Combobox Open

[Peter]

Hi,

I have a combobox (with checkboxes inside it) that is inside a RadToolbar. I have an issue where the combobox always closes when a checkbox is checked. I've noticed that when the combobox is not inside a Toolbar then it will stay open to allow me to select multiple checkboxes. I would like to have the CB inside the toolbar so I'm looking for a fix. Is this a bug? Is there a fix?

<telerik:RadToolBar>
    <telerik:RadComboBox Name="rcbProjectTypes"
        Width="120" Margin="3,1,0,1"
        ItemsSource="{Binding Path=RequestTypesSelection}"
        SelectionChanged="rcbShouldNotChange_SelectionChanged">
        <telerik:RadComboBox.ItemTemplate>
            <DataTemplate>
                <CheckBox Content="{Binding Path=Content}" Tag="{Binding Path=Id}"
                IsChecked="{Binding Path=IsChecked, Mode=TwoWay}"
                Checked="RequestTypesCheckBox_Checked"
                Unchecked="RequestTypesCheckBox_Checked"/>
            </DataTemplate>
        </telerik:RadComboBox.ItemTemplate>
    </telerik:RadComboBox>
</telerik:RadToolBar>

Thanks

Hello Peter,

 This is expected behavior of the RadToolBar because it keeps track of the focused elements inside itself.
So you can disable this behavior with the FocusManaged.IsFocusScope attached property:

<telerik:RadToolBar Width="300" Height="30" FocusManager.IsFocusScope="False" >
            <telerik:RadComboBox Name="combo" Width="120" Height="30" Margin="3,1,0,1" >
                <telerik:RadComboBox.ItemTemplate>
                    <DataTemplate>
                        <CheckBox Content="{Binding Path=Content}" Tag="{Binding Path=Id}"
                                IsChecked="{Binding Path=IsChecked, Mode=TwoWay}"
                                />
                    </DataTemplate>
                </telerik:RadComboBox.ItemTemplate>
            </telerik:RadComboBox>
        </telerik:RadToolBar>

This is also demonstrated in the attached project.
