Good day,

We have a GridView and would like to do enter key traversing instead of doing Tab key traversing, when editing a row.
Note that we are using MVVM type architecture.

For a normal grid, the following works fine, but does not seem to work on the telerik RadGridView:

public class EnterKeyTraversal

{

public static bool GetIsEnabled(DependencyObject obj)

{

return (bool)obj.GetValue(IsEnabledProperty);

}

public static void SetIsEnabled(DependencyObject obj, bool value)

{

obj.SetValue(IsEnabledProperty, value);

}

static void ue_PreviewKeyDown(object sender, System.Windows.Input.KeyEventArgs e)

{

var ue = e.OriginalSource as FrameworkElement;

if (ue != null && (e.Key == Key.Enter && ue.GetType() != typeof(Button)))

{

e.Handled = true;

ue.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next));

}

private static void ue_Unloaded(object sender, RoutedEventArgs e)

{

var ue = sender as FrameworkElement;

if (ue == null)

return;

ue.Unloaded -= ue_Unloaded;

ue.PreviewKeyDown -= ue_PreviewKeyDown;

}

public static readonly DependencyProperty IsEnabledProperty =

DependencyProperty.RegisterAttached("IsEnabled", typeof(bool),

typeof(EnterKeyTraversal), new UIPropertyMetadata(false, IsEnabledChanged));

static void IsEnabledChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)

{

var ue = d as FrameworkElement;

if (ue == null)

return;

if ((bool)e.NewValue)

{

ue.Unloaded += ue_Unloaded;

ue.PreviewKeyDown += ue_PreviewKeyDown;

}

else

{

ue.PreviewKeyDown -= ue_PreviewKeyDown;

}

Any help would be much appreciated.
Kind regards

RadRibbonWindow and XBAP

I have an assembly that can either run as a stand-alone executable or being hosted in a browser as xbap. The application opens a new RadRibbonWindow which contains a RadRibbonView.

This works fine when the assembly runs stand-alone. However, when the assembly runs as xbap, the RadRibbonWindow overlaps all window buttons (close/minimize/maximize). Is there a solution to this other than hosting the RadRibbonView in a standard WPF-window instead of RadRibbonWindow?

Regards,
Michael

Persist settings for multiple GridViews in one file

I have an app with quite a few different GridViews all of which need to have their settings persisted. Currently, I am creating a file for each GridView to persist the settings between sessions. Is there a way to consolidate this so that more than one gridview can share a settings file? Here is the current code I have for doing persistence:

/// <summary>

/// Interaction logic for BillingActivityView.xaml

/// </summary>

public partial class BillingActivityView

{

private static readonly string _appDataPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);

private static readonly string _bambooSettingsPath = Path.Combine(_appDataPath, @"Bamboo\Settings");

private static readonly string _testsGridSettingsFilePath = Path.Combine(_bambooSettingsPath, @"TestsGridSettings.bin");

private static readonly string _oldBillClassesGridSettingsFilePath = Path.Combine(_bambooSettingsPath, @"OldBillClassesGridSettings.bin");

private static readonly string _insuranceStatusGridSettingsFilePath = Path.Combine(_bambooSettingsPath, @"InsuranceStatusGridSettings.bin");

/// <summary>

/// Initializes a new instance of the <see cref="DocumentImageView"/> class.

/// </summary>

public BillingActivityView()

{

InitializeComponent();

ServiceProvider.RegisterPersistenceProvider<ICustomPropertyProvider>(typeof(RadGridView), new GridViewCustomPropertyProvider());

}

private void TestsGridView_Initialized(object sender, EventArgs e)

{

LoadGridSettings(TestsGridView, _testsGridSettingsFilePath);

}

private void OldBillClassesGridView_Initialized(object sender, EventArgs e)

{

LoadGridSettings(OldBillClassesGridView, _oldBillClassesGridSettingsFilePath);

}

private void InsuranceStatusGridView_Initialized(object sender, EventArgs e)

{

LoadGridSettings(InsuranceStatusGridView, _insuranceStatusGridSettingsFilePath);

}

public void LoadGridSettings(RadGridView gridView, string settingsPath)

{

var manager = new PersistenceManager();

if (!Directory.Exists(_bambooSettingsPath))

{

Directory.CreateDirectory(_bambooSettingsPath);

}

// Load settings if there is something to load

if (File.Exists(settingsPath))

{

try

{

var fileStream = File.OpenRead(settingsPath);

manager.Load(gridView, fileStream);

fileStream.Close();

}

catch (Exception ex)

{

System.Diagnostics.Debug.WriteLine(ex.Message, "BILLINGACTIVITYVIEW");

}

public void PersistAllGridSettings()

{

PersistGridSettings(TestsGridView, _testsGridSettingsFilePath);

PersistGridSettings(OldBillClassesGridView, _oldBillClassesGridSettingsFilePath);

PersistGridSettings(InsuranceStatusGridView, _insuranceStatusGridSettingsFilePath);

}

public void PersistGridSettings(RadGridView gridView, string settingsPath)

{

var manager = new PersistenceManager();

var stream = manager.Save(gridView);

using (var fileStream = File.Create(settingsPath))

{

stream.CopyTo(fileStream);

}

Header Text dissapears when Style changes in code

Hello, I have a RadTileView where I want to change the header background color when the tile gets minimized.
When I apply the new style the header text disappears, this doesn't happen when the new style is the same as the old one

(I know this example only works when all items are minimized, not when you maximize another item, but this is just for test purposes)

C#:

private void RadTileViewItem_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)

{

RadTileViewItem item = (sender as RadTileViewItem);

if (item.TileState == TileViewItemState.Maximized)

{

item.TileState = TileViewItemState.Minimized;

item.HeaderStyle = (Style)FindResource("TileViewItemHeaderStyle4");

}

else

{

item.TileState = TileViewItemState.Maximized;

}

XAML:

<UserControl xmlns:my="clr-namespace:WpfApplication1" x:Class="WpfApplication1.NodeView"

Using 2012.2.607.40 I receive an exception, "Cannot locate resource 'themes/genericmetrotouch.xaml'", in the VS 2010 Xaml designer when a RadNumericUpDown control is included in the form. I've included a screenshot of the exception. There is no exception when running the app, or if I display the form in Blend.

Floating Rad Pane To Dock

Hi,

I have read an article where the when we use the rad pane to float. It uses FloatingOnly. Is there a way to override this menu to use the method MakeFloatingDockable instead of MakeFloatingOnly

Also how would you re-dock a floating window from code.
