I have a problem where using a multi-binding to format axis labels correctly updates the labels, but does not resize correctly when the size of the labels change.

You can see the problem with this small example:

<Window x:Class="LabelTemplate_MultiBinding.MainWindow"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

xmlns:local="clr-namespace:LabelTemplate_MultiBinding"

Title="MainWindow" Height="768" Width="1024">

<Grid>

<Grid.RowDefinitions>

<RowDefinition Height="*"/>

<RowDefinition Height="Auto"/>

</Grid.RowDefinitions>

<telerik:RadCartesianChart x:Name="PropertyChart">

<telerik:RadCartesianChart.Resources>

<local:ChartNumberFormatter x:Key="NumberFormatter"/>

<DataTemplate x:Key="FormattedNumericAxisTemplate">

<TextBlock>

<TextBlock.Text>

<MultiBinding Converter="{StaticResource NumberFormatter}">

<Binding />

<Binding ElementName="PropertyChart"

Path="DataContext.NumericFormat"/>

</MultiBinding>

</TextBlock.Text>

</TextBlock>

</DataTemplate>

</telerik:RadCartesianChart.Resources>

<telerik:RadCartesianChart.HorizontalAxis>

<telerik:DateTimeCategoricalAxis/>

</telerik:RadCartesianChart.HorizontalAxis>

<telerik:RadCartesianChart.VerticalAxis>

<telerik:LinearAxis LabelTemplate="{StaticResource FormattedNumericAxisTemplate}" />

</telerik:RadCartesianChart.VerticalAxis>

<telerik:RadCartesianChart.Series>

<telerik:LineSeries

CategoryBinding="Date"

ValueBinding="Value"

ItemsSource="{Binding Path=Series1}">

</telerik:LineSeries>

</telerik:RadCartesianChart.Series>

</telerik:RadCartesianChart>

<StackPanel Grid.Row="1" Orientation="Horizontal">

<Label>Y Axis Format:</Label>

<TextBox Text="{Binding NumericFormat}" Width="200" />

</StackPanel>

</Grid>

</Window>

Code Behind:

public class MyPoint

{

public DateTime Date { get; set; }

public Double Value { get; set; }

}

public partial class MainWindow : Window, INotifyPropertyChanged

{

public List<MyPoint> Series1 { get; private set; }

private string _NumericFormat;

public string NumericFormat

{

get { return _NumericFormat; }

set

{

if (_NumericFormat != value)

{

_NumericFormat = value;

OnPropertyChanged("NumericFormat");

}

public MainWindow()

{

Series1 = new List<MyPoint>();

for (int i = 0; i < 5; i++)

{

DateTime date = DateTime.Today.AddDays(i);

Series1.Add(new MyPoint() { Date = date, Value = i * 1000 });

}

InitializeComponent();

DataContext = this;

}

#region INotifyPropertyChanged

public event PropertyChangedEventHandler PropertyChanged;

protected virtual void OnPropertyChanged(string propertyName = "")

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

}

#endregion

}

public class ChartNumberFormatter : IMultiValueConverter

{

public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

double number = System.Convert.ToDouble(values[0]);

string format = values[1] as string;

if (string.IsNullOrEmpty(format))

{

return number.ToString();

}

return number.ToString(format);

}

public object[] ConvertBack(object value, Type[] targetTypes, object parameter, System.Globalization.CultureInfo culture)

{

throw new NotImplementedException();

}

If you run this example, and in the Y-axis format box enter "e" then press tab to activate, you can see the numbers correctly change to scientific notation, but now they overlap the chart!

Can you recommend something to trigger the axis to be redrawn correctly?

Thanks,
Louis

Using RadGrid in other thread

Hi,
In my application, I open a modal window in a separate thread with following method:

public static void ShowInSeparateThread(Type windContent, string windowTitle, int width = 900, int height = 700)

{

var _viewerThread = new Thread(delegate()

{

var _eventAggregg = ServiceLocator.Current.GetInstance<IEventAggregator>();

_eventAggregg.GetEvent<ShowModalPopUp>().Publish(true);

var _win = new Window

{

Title = windowTitle,

DataContext = new WindowDataContext(),

WindowStartupLocation = WindowStartupLocation.CenterScreen,

WindowStyle = WindowStyle.None,

Style = Application.Current.FindResource("PopUpWindowStyle") as Style,

Padding = new Thickness(0),

Margin = new Thickness(0),

ResizeMode = ResizeMode.NoResize,

Content = ServiceLocator.Current.GetInstance(windContent),

Width = width,

Height = height,

ShowInTaskbar = false

};

typeof(Window)

.InvokeMember("_ownerHandle",

BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.SetField,

null, _win, new object[] { Process.GetCurrentProcess().MainWindowHandle });

_win.ShowDialog();

_eventAggregg.GetEvent<ShowModalPopUp>().Publish(false);

})

{

IsBackground = true

};

_viewerThread.SetApartmentState(ApartmentState.STA);

_viewerThread.Start();

}

In this window i navigate some user controls. One of that user controls contains a RadGridView binded to an ObservableCollection. When I add an item to ObservableCollection the grid items are properly notified, but when I try to remove an item from ObservableCollection i receive

The calling thread cannot access this object because a different thread owns it.

If try to change the RadGridView with native DataGrid and all works correctly. I tried also with Dispatcher.Invoke but this approach not solve my problem.

Thanks in advance for Help.

How to make column widths match in two TreeListViews?

We have two TreeListViews that we display one above the other (with some other UI bits in the middle). We desire to have the widths of the columns in these two tree views match. We do use footers in the columns, and the footer widths would need to be taken into account. Something like SharedSizeDefinition as used on Grid ColumnDefinition and RowDefinition would be ideal, if possible. How can we do this, please?

example (not intended to build; cut down from the real application code):

<telerik:RadTreeListView ItemsSource="{Binding Path=MyFirstList}" >

<telerik:RadTreeListView.ChildTableDefinitions>

<telerik:TreeListViewTableDefinition ItemsSource="{Binding ChildVMs}" />

</telerik:RadTreeListView.ChildTableDefinitions>

<telerik:RadTreeListView.Columns>

<telerik:GridViewDataColumn Header="Name" UniqueName="Name" IsSortable="True" SortingState="Ascending"

IsReadOnly="True" DataMemberBinding="{Binding Name}" />

<telerik:GridViewDataColumn Header="Value" TextAlignment="Right"

DataMemberBinding="{Binding CurrentValue, Mode=TwoWay}" >

<telerik:GridViewDataColumn.Footer>

<TextBlock FontSize="12" VerticalAlignment="Top" HorizontalAlignment="Right"

Text="{Binding Path=SomeOtherNumber, Mode=OneWay}" />

</telerik:GridViewDataColumn.Footer>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn Header="Timeline" Width="*" IsReadOnly="True"

CellTemplateSelector="{StaticResource TimelineTemplateSelector}"

CellStyle="{StaticResource TimelineCellStyle}"

FooterCellStyle="{StaticResource TimelineFooterStyle}" >

<telerik:GridViewDataColumn.Footer>

<Grid >

<Grid.RowDefinitions>

<RowDefinition Height="Auto" />

</Grid.RowDefinitions>

<telerik:RadHorizontalDataAxis Stroke="DarkRed" Foreground="Gray" ... />

</telerik:GridViewDataColumn.Footer>

</telerik:GridViewDataColumn>

</telerik:RadTreeListView.Columns>

</telerik:RadTreeListView>

<telerik:RadTreeListView ItemsSource="{Binding Path=MySecondList}" >

</telerik:RadTreeListView>

Setting the Visibility of a DataTemplate Element (TextBlock)

Hello,

I have tried binding a TextBlock in a DataTemplate to a member in the ViewModel to change it's visibility but it is not working. This is for a custom control that contains a RadCarousel where it's ItemTemplate property is set to a StaticResource in the control, the DataTemplate.

Can someone offer a suggestion for the easiest way to change the visibility of a control in a DataTemplate?

Thanks,
Reid

RadTreeView and Coded UI support (AutomationID property is blank)

We are using the RadTreeView extensively in our product and building the nodes through binding (our application follows the MVVM pattern)? I don't know if that last detail matters but when we handed off an alpha release to our QA department, they are reporting that the AutomationId property is blank when using the Microsoft Coded UI Test Builder. Is this something we need code for or is it something the Telerik control should be providing out of the box?

When appointment is extended/shrink for the first time after loading app, i get null ref exception, if i drag and drop it first and then try to expand

Hi,

I have created a database for the RadScheduleView following Telerik
tutorials. I am able to create the database, save appointments with their
categories, time markers etc.

When I load the app, I have few appointments displayed
correctly, I can double click to edit them, I can drag them around, and expand
or shrink them. However there is one problem, if I load the app and the first
thing I do is try to expand or shrink an appointment I get this:

RadRibbonView Backstage Binding Issue

Hi all,

I'm having an issue where I can't get an object to bind to my backstage view. I've used the code from the website to try and implement a recent file list from a class within another project.

A cut-down version of my BackstageViewModel to demonstrate what I'm calling:

public class BackstageViewModel : IViewModel {

public RecentFileList RecentFiles { get; set; } // the property I want to point to

public BackstageViewModel(ApplicationCommandProxy commandProxy, DataHolder data)

{

//random setup stuff

}

//and so on...

}

The RecentFileList class is a class from the WpfApplicationFramework library. You can obtain the library here. In summary, it's a holder class for a ReadOnlyObservableCollection of RecentFile called RecentFiles.

This is the portion of the code where I'm creating my items control in my backstage where ssm points to the project namespace.

<ItemsControl Name="RecentItem" DataContext="{Binding ssm:BackstageViewModel}" ItemsSource="{Binding RecentFiles.RecentFiles}" Focusable="True" DisplayMemberPath="RecentFiles">

<ItemsControl.Template>

<ControlTemplate>

<telerik:RadRibbonButton Width="285" Command="{x:Static commands:ApplicationCommands.RecentDocumentCommand}">

<StackPanel Orientation="Horizontal">

<Image Source="Resources/Open_16.png" />

<StackPanel Margin="3 0 0 0" HorizontalAlignment="Left">

<TextBlock Margin="0 0 0 2" Text="Example Study" />

<TextBlock Foreground="DimGray" Text="{Binding Path}" />

</StackPanel>

</telerik:RadRibbonButton>

</ControlTemplate>

</ItemsControl.Template>

</ItemsControl>

All I need to do is have the ItemsControl populate using the ReadOnlyObservableCollection<RecentFile> from within the RecentFileList object. I'm struggling to get it to bind correctly so any help would be greatly appreciated!

Calendar highlighting months that have data associated with them

Hi,

I am trying to use the DatePicker control but I've not found a way yet to fix the following problem

1. I need to show a calendar control that only shows months (this bits easy)
2. I have a collection of dates. I wish to highlight the month on the datepicker if that month appears in the collection of dates I have.

So it should be fairly straightforward. A calendar that only shows months and bound to a list of dates. If I have 01/01/14 in the list then Jan should be highlighted along with any other months that appear in the list (so maybe Jan, Mar, May would all be highlighted for 2014).

Thanks

RadGridView Sort

Hi,

I am comparing Telerik RadGridView with Standard dataGrid. My requirement is to create grid with custom columns. Columns cellTemplate is a View itself and column sortmemberPath is set to property to display. This property is an object which could be anything (string/int/double/list etc. ) . With DataGrid sort was working but with Telerik RadGridView it's not working (the binding etc. is still the same.). Following is an example of one of the coulmn which is being templated as per the item.

Telerik.Windows.Controls.GridViewDataColumn columnTemplate = new Telerik.Windows.Controls.GridViewDataColumn();
columnTemplate.IsSortable = true;
columnTemplate.IsCustomSortingEnabled = true;
columnTemplate.MinWidth = (item as INode).Builder.Header.Width;

columnTemplate.Header = item;

columnTemplate.Width = (item as INode).Builder.Header.Width + 10;
if (!columnGroup.Equals(string.Empty))
{
columnTemplate.ColumnGroupName = columnGroup;
}

if (item is IntegerPropertyNodeViewModel)
{
var headerName = (item as IntegerPropertyNodeViewModel).PropertyName.Substring((item as IntegerPropertyNodeViewModel).PropertyName.LastIndexOf(' ') + 1);
columnTemplate.Header = headerName;
columnTemplate.UniqueName = headerName;

var text = new FrameworkElementFactory(typeof(IntegerPropertyNodeView));

if (0 != path.Length)
{
System.Windows.Data.Binding bind = new System.Windows.Data.Binding(path);
text.SetBinding(IntegerPropertyNodeView.DataContextProperty, bind);

columnTemplate.SortMemberPath = path + ".Target";
}
SdmGridControlViewColumnGenerator.SetName(columnTemplate, "IntegerProperty");
columnTemplate.CellTemplate = new DataTemplate();
columnTemplate.CellTemplate.VisualTree = text;
columnTemplate.CellTemplate.Seal();
dataGrid.Columns.Add(columnTemplate);
}

Could you please help me in sorting issue with Telerik RadGridView.

Thanks and Regards,
Sonia

Formatted Printing of RadGridView

Hello,
I want to print/export the contents of a RadGridView. However, I want to retain the cell styles (or at least format it somewhat similar), especially for user-defined columns. For example, the number of decimal digits or the localized enum value should be retained.

When I use the ElementExporting event and check for e.Element == ExportElement.Cell,
the e.Context value points to the Column, not to the concrete cell. Is there any way to get the concrete GridViewCell? Or at least get the bound item?
