Main window in background after closing a RadWindow

Hi everyone,

I am developing a WPF application in my company.
I use RadControls for WPF Q3 2013 trial version.

I have written a sample project.
The MainWindow contains a Button and I have written an handler to the Button's Click event.

Here is the MainWindow's code-behind :

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows;

using System.Windows.Controls;

using System.Windows.Data;

using System.Windows.Documents;

using System.Windows.Input;

using System.Windows.Media;

using System.Windows.Media.Imaging;

using System.Windows.Navigation;

using System.Windows.Shapes;

using Telerik.Windows.Controls;

namespace MainWindowInBackground

{

/// <summary>

/// Interaction logic for MainWindow.xaml

/// </summary>

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

}

private void Button_Click(object sender, RoutedEventArgs e)

{

RadWindow l_hostWindow = new RadWindow()

{

Owner = System.Windows.Application.Current.MainWindow,

WindowStartupLocation = WindowStartupLocation.CenterOwner,

Content = "Test"

};

l_hostWindow.Show();

MessageBox.Show("MessageBox", "MessageBox", MessageBoxButton.OK, MessageBoxImage.Information, MessageBoxResult.OK);

}

The attached picture 1.png shows the application before closing the RadWindow.
The attached picture 2.png shows the application after closing the RadWindow.
The main window has been automatically put in background - behind all other running applications's window - after closing the RadWindow.
Why ?

Tooltip format

I have a project where the heat map exactly meets my needs, but I need to be able to display a tooltip with custom formatted text, including units and some other information included with the data point.

How would you style the tooltip format in xaml and/or code behind?

Columns not appears in RadGridView

Hi, I am binding a Dataset to a RadGridView, but I am getting some strange behaviors. I already try to bind the dataset, datatable or default table view. Same Result.
Other problem is when my datatable has no rows (only columns defined). Nothing is displayed, even the column itself.

I had attached some images to show what´s happen.

Thanks

GridViewComboBoxColumn - How to Sort items inside the RadComboBox?

I have a RadGridView where on of the columns is a GridViewComboBoxColumn.

How do I sort the Items inside the the RadComboBoxs alphabetically?

Assume I have three cities: Manchester, Zurich and Aberdeen. I want my RadComboboxes to display alpabetically

Aberdeen
Manchester
Zurich

The underlying data is rather big: There are some ten-thousands of grid-rows and the items inside the RadComboBoxes can also be some ten-thousands (RadCombox items are city names). Thanks to virtualization the performance is actually very good.

I don't want to sort each single ComboBox, since this might slow down the Grid considerably.
I found documentation and some forum posts about SortingState, but that was not helpful for my problem.

NullReferenceException when using PdfViewer in an AddIn

I try to use the PdfViewer in an addin (using the .net managed addin framework), hosted in a winform host application. When I open a pdf file I get this exception:

   at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Utils.Helper.get_Dispatcher() in c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Documents\Fixed\Core\FormatProviders\Pdf\Utils\Helper.cs:line 25

   at Telerik.Windows.Documents.Fixed.FixedDocumentStreamSource.<>c__DisplayClass8.<LoadDocument>b__6() in c:\TB\105\WPF_Scrum\Release_WPF\Sources\Development\Documents\Fixed\FixedDocumentViewers\Fixed\FixedDocumentStreamSource.cs:line 180

   at System.Threading.ThreadHelper.ThreadStart_Context(Object state)

   at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)

   at System.Threading.ThreadHelper.ThreadStart()

I suspect the helper class is using Application.Current.Dispatcher. Application.Current is null in our environment.

Is there a work around for this problem so I can use the viewer in an addin?

Thank you,

Fonger.

unable to set min or max property value of radslider in code behind

Hi.
I have a problem setting minimum or maximum values for a RadSlider I need to generate by c# code inside a propertygrid with the help of FrameworkElementFactory.

Value binding and setting the grid column work perfectly but I am not able to set min or max slider value (and tickfrequency, too - are they readonly?).

What do I do wrong here? Or is there a better way to add properties like a radslider control inside a radpropertygrid on the fly?

Lars

Here is a code snipet:

FrameworkElementFactory slider = new FrameworkElementFactory(typeof(RadSlider));

slider.SetBinding(RadSlider.ValueProperty, new Binding(path) { Mode = BindingMode.TwoWay });

slider.SetValue(RadSlider.MinimumProperty, 0);

slider.SetValue(RadSlider.MaximumProperty, 100);

slider.SetValue(Grid.ColumnProperty, 1);
