In my usage of the ChartCiew I have three line series drawn on a chart per date, all of which share the same colour which are distinguished by using the DashArray property of the LineSeries class to make one solid, one dotted (1,1) and one dashed (3,3). Each different date shown on the chart uses a different colour.

I can't seem to figure out how to make a legend that replicates the line drawn on the chart using the dash array property, do you have any advice?

I have looked at your examples and can't see one that does what I want.

I can't really attach the code but I have attached an image showing a chart containing two LineSeries (one solid and one dashed) and my desired legend to indicate my requirements.

Thanks,

RadRibbonButton - SaveCommand - FolderBrowserDialog

Hi,

is it possible to set the Root-Fodler of the FolderBrowserDialog from the RadRichTextBoxribbonUI? <telerik:RadRichTextBoxRibbonUI>

lderBrowserDialog dialog = new FolderBrowserDialog();

dialog.SelectedPath = programFiles;

dialog.ShowDialog();

in the Backstage Area i use this RadRibbonButton and the : telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=SaveCommand}"

<telerik:RadRibbonButton BorderBrush="Gray" CommandParameter="pdf" CornerRadius="3" Height="80" telerik:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=SaveCommand}" telerik:RadRichTextBoxRibbonUI.ShouldCloseBackstage="True" Width="90">

<StackPanel Width="90">

<Image HorizontalAlignment="Center" Source="pack://application:,,,/Telerik.Windows.Controls.RichTextBoxUI;component/Images/MSOffice/ApplicationMenu/Pdf.png" Stretch="None" />

</StackPanel>

Is it possible to set the RootFolder of the "SaveCommand"??? Something like RadRibbonButton.FolderDialog.SelectedPath= ??

Thanks a lot

Change the DataServiceContext of a RadDataServiceDataSource?

The Data Service sample works fine when you instantiate a concrete service context object directly in the XAML of the RadDataServiceDataSource.

Should it be possible to data bind to the DataServiceContext property of a RadDataServiceDataSource instead?

I have an app that allows the choice of several OData services. When a service is chosen, I dynamically generate a service client proxy, and activate a new instance of that proxy's exported DataServiceContext-derived class. Now I want to bind that to my RadDataServiceDataSource (and of course change the binding to a completely different context if another OData service is chosen).
These are all read-only services, so I'm not concerned about maintaining any consistency of client-side update state.

It seems that when the DataServiceContext is set via a binding, the grid shows no data.

It seems that queries are never issued to the context:

System.ArgumentException: Could not find a matching query method on the DataServiceContext

Maybe the RadDataServiceDataSource is reflecting on the declared type of the bound property (DataServiceContext) instead of its runtime type (generated in the proxy and unavailable to me at design-time)?

Mail Merge UI Text Before & After if not empty

Hi,

Is it possible to set the mail merge features via the UI to add text before and text after a field if it isn't empty?
I have seen that this is possible in code behind but I can't see to find a way to do it via the RadRichTextBox UI.

Thank you for your time,

Rob

Enter key transversal

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;

}
