    Hi,
    Am having some issues with the Dropdown content in RadDropDownButton.
    I get multiple instances of the dropdown content (attached screen shot).
    Below is my xaml.

    <telerik:RadDropDownButton AutoOpenDelay="0:0:0.0" Grid.Column="1" Grid.Row="0" FlowDirection="RightToLeft" DropDownButtonPosition="Left" 
                                                           Visibility="{TemplateBinding SearchHistoryListVisibility}" KeepOpen="False" DropDownMaxHeight="170"
                                                           IsOpen="{Binding IsSearchHistoryOpen, Mode=TwoWay}">
                                        <telerik:RadDropDownButton.DropDownContent>
                                            <Grid>
                                                <Grid.ColumnDefinitions>
                                                    <ColumnDefinition Width="{Binding SearchHistoryWidth}" />
                                                </Grid.ColumnDefinitions>
                                                <ListBox Grid.Column="0" FlowDirection="LeftToRight" 
                                                         ItemContainerStyle="{StaticResource SearchHistoryItemStyle}" BorderThickness="0.25" BorderBrush="DarkGray"
                                                         ItemsSource="{Binding Path=SearchHistoryList}" 
                                                         SelectedValue="{Binding Path=SelectedSearchQuery, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" 
                                                         HorizontalAlignment="Stretch" />
                                            </Grid>
                                        </telerik:RadDropDownButton.DropDownContent>
                                    </telerik:RadDropDownButton>

    Am trying to close the dropdown content on click of a listbox item. Am setting  IsSearchHistoryOpen=false from SelectedSearchQuery property.

    This happens only when I specify Mode=TwoWay in 
    IsOpen="{Binding IsSearchHistoryOpen, Mode=TwoWay}".
    But if I dont specify the twoway mode, the dropdowncontent doesnt close when i click the listbox item.

    Any help is much appreciated.

    Thanks

    Hello Varikkara,
    Thank you for the feedback! Unfortunately I wasn't able to reproduce this issue so I'd like to ask you for some more code snippets, the exact version of your dlls and steps to reproduce the bug or a sample project.
    I've attached the sample project I used for testing so you could examine it and tell us what we're doing wrong.
    We're looking forward to hearing from you.
    p.s. From what I see in the png you're using a custom RadDropDownButton style and if that's true could you please test your solution without it ?
