RadWindow.ShowDialog doesn't stay on top

Hi,

I'm using this code to show a modal RadWindow:

private void SendCommandExecuted(object parameter)

{

PopupDeviceView popupDeviceView = new PopupDeviceView();

PopupDeviceViewModel popupDeviceViewModel = (PopupDeviceViewModel)popupDeviceView.DataContext;

RadWindow radWindow = new RadWindow();

radWindow.Content = popupDeviceView;

radWindow.WindowStartupLocation = WindowStartupLocation.CenterOwner;

radWindow.ResizeMode = ResizeMode.NoResize;

radWindow.CanClose = false;

radWindow.CanMove = false;

radWindow.ShowDialog();

}

it opens a RadWindow as modal, in the main window, but when I minimize that main window - my modal RadWindow dissapears, its only available with Alt+Tab windows keys - and only the main window is shown. And the worst - main window's button, that opened my RadWindow - can be hit with Enter key (not with mouse tho).

What should I do to make it trully 'modal'? TIA

Radial Tree layout doesn't respect container size

Greetings, Telerik!

In out project we use diagram with all available types of layout.
Almost all layout types works great but radial tree behaves weird and it's unclear how the one can fix it without your help.
Mostly, we have a lot of containers in diagram and when radial tree is applied it looks fine, but when container that was placed above is expanded it is placed above and connected container isn't visible. Attached file can explain it better than thousand words.

In project we agreed to use next TreeLayoutSettings (regarding Radial tree)

StartRadialAngle = 1.0,

EndRadialAngle = 6.5,

RadialFirstLEvelSeparation = 150.0,

RadialSeparation = 150,

KeepComponentsInOneRadialLayout = true,

I believe that OrgTreeRouter means nothing when layout is being done.
Also we're filling collection of Roots for settings according to some rules (mostly the root will be the shape/container with outgoing connections).

Is it possible for radial tree to respect margins and place containers with some margins?

Thanks in advance!

AutoCompleteBox loses highlighting when the item collection changes while the AutoCompleteBox is active and the popup is open.

AutoCompleteBox loses its highlighting when the itemsource collection changes. To reproduce this issue type in the AutoCompleteBox and while it’s active and the popup is open, trigger a collection change event. The highlighting will automatically disappear, now if the collection changes again the highlighting reappears. This keeps toggling back and forth.

Attached is the screenshot.
Below are the code snippets.

using System;

using System.Collections.Generic;

using System.Collections.ObjectModel;

using System.Linq;

using System.Text;

using System.Threading;

using Telerik.Windows.Controls;

namespace HighlightMatchingItemsText

{

public class Country

{

public string Name { get; set; }

public string Capital { get; set; }

}

public class ViewModel : ViewModelBase

{

private ObservableCollection<Country> countries;

public ViewModel()

{

this.Countries = new ObservableCollection<Country>()

{

new Country() { Name = "Australia", Capital = "Canberra" },

new Country() { Name = "Bulgaria", Capital = "Sofia" },

new Country() { Name = "Canada", Capital = "Ottawa" },

new Country() { Name = "Denmark", Capital = "Copenhagen" },

new Country() { Name = "France", Capital = "Paris" },

new Country() { Name = "Germany", Capital = "Berlin" },

new Country() { Name = "India", Capital = "New Delhi" },

new Country() { Name = "Italy", Capital = "Rome" },

new Country() { Name = "Norway", Capital = "Oslo" },

new Country() { Name = "Russia", Capital = "Moscow" },

new Country() { Name = "Spain", Capital = "Madrid" },

new Country() { Name = "United Kingdom", Capital = "London" },

new Country() { Name = "United States", Capital = "Washington, D.C." },

};

var o = System.Reactive.Linq.Observable.Start(() =>

{

//starts on a background thread.

while (true)

{

Thread.Sleep(6000);

this.Countries = new ObservableCollection<Country>()

{

new Country() { Name = "Australia", Capital = "Canberra" },

new Country() { Name = "Bulgaria", Capital = "Sofia" },

new Country() { Name = "Canada", Capital = "Ottawa" },

new Country() { Name = "Denmark", Capital = "Copenhagen" },

};

Console.WriteLine("Collection Changed");

}

});

}

public ObservableCollection<Country> Countries

{

get { return this.countries; }

set

{

if (this.countries != value)

{

this.countries = value;

this.OnPropertyChanged(() => this.Countries);

}

Styling problems with RadGridView

I am having some issues with finding what to call to set certain colors. If you look at the attached RadGridView you will see these problems:

1. The child template has that light grey background.
2. On the selected tab it is white.
3. The selected grid header column is an orageish color (also is an orangeish color when moused over).

What are the proper ways to fix these color issues? I've tried changing the style on almost everything and have had no success.

How can i change the color of that column header

Thanks

ListBox scrolling when item is clicked when using smooth scrolling

I'm trying to use the RadListBox control because of it's drag and drop features, but am running into a problem that only shows up when smooth scrolling is enabled. I've enabled smooth scrolling using the method posted elsewhere on the forums by setting the CanContentScroll property to False.

However, when this is enabled, and I click on an item in the list, the whole list scrolls up so that the clicked item is at the bottom of the viewable area. The resulting effect is that over several clicks, I've scrolled to the top of the list. This behavior doesn't happen when the ListBox scrolls by item (when CanContentScroll is not set to false).

I do not need the selection functionality of the ListBox, and I'm using it just for the built-in drag and drop features. If there's another way to do the drag and drop without a Listbox, that's fine.

I need the ListBox to not scroll when an item is clicked, or another solution to the problem. Without a resolution, I cannot use smooth scrolling, as this will be a deal-breaker for any user.

Here's a link to a project that will show the behavior: https://dl.dropboxusercontent.com/u/3583840/ProgrammingSolutions/TelerikDragAndDropTest2.zip

The project is for the Q1 2014 release, but I've tried the most recent one and I get the same results.

RadRibbonWindow- Auto hide taskbar won't popup

Can someone please comment on the satus of this bug.
I see a silverlight issue regarding this still open in PITS but do not know if this is already being tracked for WPF.

http://www.telerik.com/support/pits.aspx#/public/wpf/7503

When using RadRibbonWindow maximized with Windows Taskbar set to Auto hide, when I move the mouse to the bottom of the screen, the task bar does not popup.
If I use a standards WPF window it does.

This works OK

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" >
Blah...   

  </Window>

but not this

<telerik:RadRibbonWindow x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
                         
                         
Blah...       
  
</telerik:RadRibbonWindow>
