WPF Popup Problem

[furqanms]

I have a little problem in a XAML application. When I use a popup in a
WPF application, I am not able to get rid of the popup from the view
even if I do Alt-Tab to move focus to other applications.

Even I have set stayopen=false

Following is the code which I have done.

 <!-- Middle Product List --> 
        <GroupBox Grid.Column="1" Grid.Row="2"> 
            <ScrollViewer VerticalScrollBarVisibility="Disabled"  HorizontalScrollBarVisibility="Disabled"> 
                <ListBox Style="{DynamicResource PhotoListBoxStyle}"  
                Name ="PhotoListBox"  
                Margin="5"  
                SelectionMode="Single"  
                ItemsSource="{Binding}"  
                HorizontalAlignment="Center"  
                VerticalAlignment="Center"  
                SelectedIndex="0"        
                 
                > 
                    <ListBox.ItemTemplate> 
                        <!--<DataTemplate> 
                    <Image Source="{Binding Path=ProductImagePath}" /> 
                </DataTemplate>--> 
 
                        <DataTemplate > 
                            <Grid VerticalAlignment="Center" HorizontalAlignment="Center" Margin="6"> 
                                <!-- Drop Shadow --> 
                                <Border HorizontalAlignment="Stretch" VerticalAlignment="Stretch" CornerRadius="4" Background="#44000000"> 
                                    <Border.RenderTransform> 
                                        <TranslateTransform X="5" Y="5" /> 
                                    </Border.RenderTransform> 
                                    <Border.BitmapEffect> 
                                        <BlurBitmapEffect Radius="8" /> 
                                    </Border.BitmapEffect> 
                                </Border> 
                                <!-- Image Template --> 
                                <Border Padding="4" Background="White" BorderBrush="#22000000" BorderThickness="1"> 
                                    <StackPanel Orientation="Vertical"> 
                                        <Image Height="150" Width="100" Source="{Binding Path=ProductImagePath}"/> 
                                        <!--<Label Content="{Binding Metadata.DateImageTaken}"> 
                                            <Label.ToolTip> 
                                                Only JPeg images with a stored thumbnail will display a thumbnail during preview. 
                                            </Label.ToolTip> 
                                        </Label>--> 
                                    </StackPanel> 
                                </Border> 
                            </Grid> 
                        </DataTemplate> 
 
                    </ListBox.ItemTemplate> 
                     
                    <ListBoxItem HorizontalContentAlignment="Stretch"  Background="Blue"></ListBoxItem> 
                    <ListBoxItem HorizontalContentAlignment="Stretch" Background="Blue" Name="ListBoxItem1">Click Me</ListBoxItem> 
                    <ListBoxItem HorizontalContentAlignment="Stretch" Background="Blue"></ListBoxItem> 
                </ListBox> 
            </ScrollViewer> 
        </GroupBox>  
 
 <!-- Pop-Up Product Information Window --> 
        <Popup Name="ProductInfo"  
                   StaysOpen="False"    
                   Placement="Center"   
                   MaxWidth="200" 
                   PopupAnimation="Slide"  
                   AllowsTransparency = "False"> 
 
            <Border BorderBrush="Beige"  
                                BorderThickness="2"  
                                Background="White">  
 
                <TextBlock Name="abc" Margin="10"

                            </TextBlock> 
 
            </Border> 
        </Popup> 
        <!-- Pop-Up Product Information Window -->

This is a code behind

Public Class PopupTest 
 
    Private Sub run_MouseEnter(ByVal sender As Object, ByVal e As MouseEventArgs) 
        popLink.IsOpen = True 
    End Sub 
 
    Private Sub lnk_Click(ByVal sender As Object, ByVal e As RoutedEventArgs) 
        Process.Start((CType(sender, Hyperlink)).NavigateUri.ToString()) 
    End Sub 
 
    Private Sub ListBoxItem1_Selected(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles ListBoxItem1.Selected 
        popLink.IsOpen = True 
    End Sub 
End Class

case 1 : When I clicked on the term, it will popup and disapear when I clicked outside anywhere
Case 2 : I have listbox and have a list item named "click me" , when I clicked on this list item the popup will appear but when I click outside anywhere it is not going to be disapear.


Please help me to solve this problem


Thanking you in advanced

I have run into the same issue where the Popup will not disappear when the IsOpen property is set to True in the LisBoxItem's Selected event handler. I do not understand why this is the case, although I have not looked deeply into it.

Regardless, it looks like you found a workaround here:

There may also be a solution to the problem that does not need to make use of Popups, but that's for you to decide given your particular scenario.
