Do you only intend to target Windows IE customers? If so, you can use an XBAP; if not, you need to look at Silverlight.

Hi,
Yes. Just go ahead with XBAP application which enables your application as desktop application without any performance issue.

If you are fine with XBAP, you might as well use ClickOnce and deploy a WPF desktop app. That'd be a far more convenient approach.

hello,
i have trouble with the wpf toolkit accordion control.
i have a UserControl which creates a dynamic nested accordion control (3 levels).
when the 3rd level accordionItem is clicked a new usercontrol, also a accordion but in XAML, will be added to the content of the 3rd level accordionItem.
both usercontrols have a link to a ResourceDictionray (Theme) like this:
xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Layout.Toolkit">
<Grid Name="MainGrid">
<Grid.Resources>
<ResourceDictionary Source="../View/Themes/CustomAccordion.xaml"></ResourceDictionary>
</Grid.Resources>
</Grid>
the problem is, that the XAML accordion display my theme configuration but the dynamic created accordion won't display the same theme.
does anybody know why?
thanks for any help

i checked my code and found the problem
accordionItem.SetResourceReference
was set and does override my ResourceDictonary Source

Hi,
I am working with a WPF project and have a string property Address.
StackPanel Grid.Row="4" Grid.Column="1" Grid.ColumnSpan="2" Margin="2,2,10,2" Visibility="{Binding Address, Converter = {StaticResource FormatAddress}}"
The converter FormatAddress is returning Visibility.Visible if Address is !string.Empty and !="".
Can I use this converter if I want show the StackPanel if the Address is string.Empty or ""? Or do I have to create a new converter for this case?
Regards
Olof

Why not just use string.IsNullOrWhitespace in the converter to decide whether the string is empty or not?

He can, provided he is using .Net 4.0.
As far as I remember (from a previous discussion), this does not exist in versions before 4.0.

True, but it's easy to replicate the logic.
public static bool IsNullOrWhitespace(this string text)
{
if (string.IsNullOrEmpty(text))
return true;
return text.Trim() == string.Empty;
}

Yes. You can just use the same converter. make sure that your converter always returns Visibility type instead null or string.

You could probably use a trigger. You can set visibility based on the true/false.

Hello,
i have created a listbox that uses databinding that contains many items
each item has two 2 textblock and one hyperlink button.
one textblock is named ID and is Collapsed.
when i press the hyperlink button i want to get the value stored in ID so i can pass it to a new Page that i open.
Is this possible, and how?

I don't know about others but I used :-
private void CheckBox_Unchecked(object sender, RoutedEventArgs e)
{
ComboBox cmb = (ComboBox)((sender as Control).Parent as Panel).Children.First(x => (x as Control != null) && (x as Control).Name == "cmbShipState");
cmb.Visibility = System.Windows.Visibility.Visible;
}
to find a sibling of a control on its click event.
I will appreciate if somebody can show me a better way to accomplish the same.
Note : The code is of different context but I think you can convert it for your scenario. 
Thanks and Regards

You might want to consider the command approach.
Pass in the id as the command parameter.

My scenario is little different as I have to show/hide few controls in row detail template of data-grid - please suggest me something for that - an attached code example would be of great value.
Thanks and Regards

Hi,
Its simple. Just get the data context of your hyperlink button or combobox, and get the business object property to get the actual value which you bound with textblock. Hope you can get my point.

this is my listbox with the datatemplate
The listbox is loaded with many different items, the header=hyperlink does not have unique contents.
What i want is to pass the current HiddenID that correspons to the hyperlink
Ex:
hiddenID = 34
Hyperlink = "Recent events"
Content = "short description"
when i press "Recent events" and trigger the hyperlinkbutton event i want to be able to get the value from hiddenID
<ListBox x:Name="ListboxNews" ItemTemplate="{StaticResource NewsTemplate}" ItemsSource="{Binding _News}" Margin="8,38,8,8" Opacity="1" BorderThickness="0" Background="White" />
<DataTemplate x:Key="NewsTemplate">
<Grid Background="White" HorizontalAlignment="Left" Height="59" VerticalAlignment="Top" Width="265">
<HyperlinkButton x:Name="NewsHyperLink" Content="{Binding Header}" FontSize="18.667" FontWeight="Bold" FontFamily="/StartPage;component/Fonts/Fonts.zip#Calibri" Click="HyperlinkButton_Click" Background="{x:Null}" HorizontalAlignment="Left" VerticalAlignment="Top" d:LayoutOverrides="HorizontalAlignment, VerticalAlignment" Margin="10,0,0,0"/>
<TextBlock x:Name="Content" Text="{Binding Content}" TextWrapping="Wrap" Width="265" FontFamily="/StartPage;component/Fonts/Fonts.zip#Calibri" FontSize="16" Foreground="Black" HorizontalAlignment="Left" VerticalAlignment="Top" Margin="12,23,0,0" />
<TextBlock x:Name="HiddenID" Text="{Binding NewsID}" Width="20" VerticalAlignment="Top" d:LayoutOverrides="VerticalAlignment" FontSize="16" HorizontalAlignment="Left" Margin="-2,0,0,0" />
</Grid>
</DataTemplate>

Hi,
Here is the Click Event handler which i said
private void Link1_Click(object sender, RoutedEventArgs e)
{
string id= ((sender as HyperlinkButton).DataContext as YourBusineesObject).HiddenID;
}
Let me know if this works.

Yep, i've done a fair amount of goggling with no success. Did anyone ever figure out a solution to this problem?
The one solution that i tried was connecting to the textbox's lostfocus event, and then setting e.handled = true. Yep it didn't work xD

You might want to try something like editing a text box's selected text style to include a border or a rectangle that displays on top of the selected text once some text is selected and focus is lost.
Does this[^] custom control help by any chance?

I figured it out. Was pretty easy lol.
Just added this to my main window to consume the WM_KILLFOCUS message, and by doing so i disabled the textbox from ever getting notified that focus for the app has been lost
<br />
const int WM_KILLFOCUS = 8;<br />
<br />
protected override void OnSourceInitialized(EventArgs e)<br />
{<br />
base.OnSourceInitialized(e);<br />
HwndSource source = PresentationSource.FromVisual(this) as HwndSource;<br />
source.AddHook(WndProc);<br />
}<br />
<br />
IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)<br />
{<br />
if (msg == WM_KILLFOCUS)<br />
handled = true;<br />
<br />
return IntPtr.Zero;<br />
}<br />
Additionally, i also subscribed to the TextBox's LostFocus event in order to prevent the textbox from losing focus to another control, which would also result in the TextBox loosing the selection highlighting.
<br />
private void textBoxReadingMaterial_LostFocus(object sender, RoutedEventArgs e)<br />
{<br />
e.Handled = true;
}<br />
