Hi!
I have a question/problem with DragAndDrop and listBoxes.
I have two collections:
   var coll1 = new ObservableCollection<User>() {new User() {Id = 1}, new User() {Id = 2}};
var coll2 = new ObservableCollection<User>() { new User() { Id = 2 }, new User() { Id = 4 } };
listbox1.ItemSource=coll1;
listbox2.ItemSource=coll2;

I can copy some items from listbox1 to listbox2 via draganddrop, but when i want to drag from listbox1 to listbox2 item User(id=2) I put listbox2.AllowDrop= false, because i don't want that listbox2 contains two equal items User(id=2)

So it works, but i want more ;) I want to show why it is impossible to drop item to listbox.

        private void OnDragInitialize(object sender, DragInitializeEventArgs e)
        {
            e.AllowedEffects = DragDropEffects.Copy;
            var data = ((FrameworkElement)e.OriginalSource).DataContext;
            e.DragVisual = new DragVisual()
            {
                Content = data,
                ContentTemplate = this.Resources["DragTemplate"] as DataTemplate
            };
            DataObject dataObject = new DataObject();
            dataObject.SetText(data.ToString());
            dataObject.SetData("DragData", data);
            dataObject.SetData("Text", data.ToString());
            e.Data = data;
        }

I want to show something like this link

Thanks in advance!

RadGridView in not selected RadTabItem has 0 items

Hello,

I have a problem with RadGridView inside RadTabItem - same as in this your example (WpfApplication3.zip). RadGridView on 3rd RadTabItem has no items before you select it.

Try to change your code:

public MainWindow()

{

InitializeComponent();

this.radGridView1.ItemsSource = GenerateProducts();

this.radGridView2.ItemsSource = GenerateProducts();

MessageBox.Show(radGridView1.Items.Count.ToString());

MessageBox.Show(radGridView2.Items.Count.ToString());

}

There are 19 items in radGridView1 in 1st RadTabItem, but radGridView2 in 3rd RadTabItem has 0 items. In my project I have same problem with version 2011.3.1220.35 and 2012.1.0326.35 too. With previous version used in my project (2010.3.1110.35) it works fine.

Can you help me, please?

Thanks,
Maros

MenuItem and updating IsChecked

Hello,
I'm using RadMenu in an MVVM Caliburn Micro application,I've also a RadDocking that contains my views ... some views are sistem views and they should be enabled/disabled by a menu called Views...I've got difficulties since if I just use the menu (check/unchek) for showing/hiding it work fine, but if I start closing from the "X" I got the IsChecked desinked with the real view state.... since I use this this piece of code for the RadMenu, where do I specify the SubmenuOpened event? If I'm able to access it I can calculate the state of the views...

<UserControl.Resources>

<BooleanToVisibilityConverter x:Key="booleanConverter" />

<selectors:MenuItemTemplateSelector x:Key="templateSelector"></selectors:MenuItemTemplateSelector>

<HierarchicalDataTemplate x:Key="MenuItemTemplate" ItemsSource="{Binding Items}">

<TextBlock Text="{Binding Text}" cal:Action.TargetWithoutContext="{Binding}"

Visibility="{Binding IsVisible,Mode=TwoWay,Converter={StaticResource booleanConverter}}" />

</HierarchicalDataTemplate>

</UserControl.Resources>

<Grid>

<telerik:RadMenu x:Name="MenuList" ClickToOpen="False" BorderBrush="Transparent" ItemsSource="{Binding Items}" ItemTemplate="{StaticResource MenuItemTemplate}"

cal:Message.Attach="[Event ItemClick] = [Action OpenView($eventArgs)]" >

<telerik:RadMenu.ItemContainerStyle>

<Style TargetType="telerik:RadMenuItem">

<Setter Property="IsSeparator" Value="{Binding IsSeparator}" />

<Setter Property="IsChecked" Value="{Binding IsChecked, Mode=TwoWay}" />

<Setter Property="IsCheckable" Value="{Binding IsCheckable}" />

<Setter Property="StaysOpenOnClick" Value="{Binding IsCheckable}" />

</Style>

</telerik:RadMenu.ItemContainerStyle>

</telerik:RadMenu>

</Grid>

</UserControl>

Thanks

RadPane Maximize size on secondary high res display incorrect

Hi there,

We have identified a bug with the RadPane/RadDocking control's maximize functionality, which we would appreciate your feedback on as soon as possible.

When maximizing a floating RadPane on a secondary display that has a resolution greater (1920*1200) than that of the primary display (1600*1200) the RadPane is not sized to the extent of the display, but extends beyond it. This is only the case when the resolutions of the displays are setup in this way; if the primary screen has the greater resolution it does not occur. Unfortunately this is a usual setup for laptop users who have a large display available when they are working in the office.

However, we have resolved this issue (or very similar) in the past in some of our own window management code, so may be able to offer a potential resolution. We experienced the same symptoms in our custom windows as a result of using a WindowStyle of None and then using Win32 interop to set the minmaxinfo appropriately to avoid overlapping the Windows TaskBar. The calculations for some reason became invalid in the scenario described above. The solution implemented was simply not to adjust the minmaxinfo when the window was found to be not on the primary screen.

Looking forward to your feedback,

Chris

[Solved] InputBinding LeftDoubleClick breaks after upgrading to 2012-Q1

I have a StackPanel within a GridView with its InputBindings set to LeftDoubleClick as shown below.

<TelerikGW:RadGridView x:Name="radGridView" Grid.Row="2"

ItemsSource="{Binding SearchResult.Results}"

ScrollViewer.HorizontalScrollBarVisibility="Visible"

MinWidth="50"

HorizontalAlignment="Stretch"

>

<TelerikGW:RadGridView.Columns>

<TelerikGW:GridViewDataColumn Width="*" MinWidth="50">

<TelerikGW:GridViewDataColumn.Header>

<Label Content="Found" />

</TelerikGW:GridViewDataColumn.Header>

<TelerikGW:GridViewColumn.CellTemplate>

<DataTemplate>

<StackPanel Margin="0"

HorizontalAlignment="Left"

VerticalAlignment="Top"

Orientation="Horizontal"

>

<StackPanel.InputBindings>

<MouseBinding Command="{Binding Path=ResultClick}" MouseAction="LeftDoubleClick" />

</StackPanel.InputBindings>

<Image Height="20"

MaxWidth="100"

Margin="0"

Source="{Binding ClassIcon.ContentBytes}"

Stretch="Uniform" />

<WV:TextHighLighter Margin="10"

ToolTip="{Binding ResultItem.MatchTerm}"

Padding="0"

Text="{Binding Path=ResultItem.MatchTerm}"

TextToHighLight="{Binding DataContext.SearchedTerm, RelativeSource={RelativeSource AncestorType=WV:GlobalSearch}}" />

</StackPanel>

</DataTemplate>

</TelerikGW:GridViewColumn.CellTemplate>

</TelerikGW:GridViewDataColumn>

</TelerikGW:RadGridView.Columns>

</TelerikGW:RadGridView

At runtime, on double cicking it throws the following exception.

[System.InvalidCastException] = {"Unable to cast object of type 'System.Windows.Documents.Run' to type 'System.Windows.FrameworkElement'."}

Message = "Unable to cast object of type 'System.Windows.Documents.Run' to type 'System.Windows.FrameworkElement'."

Source = "Telerik.Windows.Controls.GridView"

StackTrace = "   at Telerik.Windows.Controls.GridView.GridViewRow.ShouldHandleMouseDoubleClick(MouseButtonEventArgs e)\r\n   at Telerik.Windows.Controls.GridView.GridViewRow.OnMouseDoubleClick(MouseButtonEventArgs e)\r\n   at System.Windows.Controls.Control.HandleDouble...

It works if the MouseAction is set to LeftClick, which I don't want to use.

It had worked with 2011-Q3.

Can someone get back with a solution for this please?

Best Regards,

Gajan

How to interact with DocumentPanes?

Good evening,

This may be a bit of a noob question but how does one interact with RadDocumentPane from a main window?

Let me detail my Situation.

My main window contains a RadDockingControl. The RadDockingControl has an area for a DocumentHost.

<telerikDocking:RadDocking.DocumentHost>

<telerikDocking:RadSplitContainer>

<telerikDocking:RadPaneGroup x:Name="radDockingDocumentHost" />

</telerikDocking:RadSplitContainer>

</telerikDocking:RadDocking.DocumentHost>

In Code Behind I programmatically add RadDocumentPanes to the DocumentHost whenever a button is pressed.

private void btnBlankNewOrder_Click(object sender, RoutedEventArgs e)

{

//ADD NEW DOCUMENT PANE _ RadRichTextBox

var pane = new RadRichTextBoxAutoComplete(products);

pane.Title = "Rob's Test Pane";

radDockingDocumentHost.Items.Add(pane);

}

The RadDocumentPanes being added are a modified UseControl which now inherits the RadDocumentPane.

<telerik:RadDocumentPane x:Class="TAS2.RadRichTextBoxAutoComplete"

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

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

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:telerikDocking="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Docking"

xmlns:telerikQuickStart="clr-namespace:Telerik.Windows.Controls.QuickStart;assembly=Telerik.Windows.Controls"

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

mc:Ignorable="d">

.................MY CONTROL CONTENT HERE (Cut Out for this Example) ...................

</telerik:RadDocumentPane>

Each RadDocumentPane hosts a Grid (actually there are nested Grids which have been cut out for this example) that contain a RadRichTextBox.

<telerik:RadDocumentPane x:Class="TAS2.RadRichTextBoxAutoComplete" ..... >

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition />

</Grid.ColumnDefinitions>

<telerik:RadRichTextBox x:Name="radRichTextBox" AcceptsReturn="True" Width="800" Margin="10" Padding="10" Grid.Column="0"

FontSize="14" IsSpellCheckingEnabled="False" DocumentInheritsDefaultStyleSettings="True" />

</Grid>

</telerik:RadDocumentPane>

Going back to my Main Window that contains the main RadDocking control, I have a Ribbon menu containing several buttons (see the attached image).

How do I interact with the programatically added RadDocumentPanes and their respective RichTextBox's when pressing a button in the Ribbon menu?

For example, suppose that the ribbon bar contains a "Paste" button. How do I make the "Paste" command associate itself with the RichTextBox of the current DocumentPane in view?

I would attach samples of my code but it won't let me add them, only images.

Thank you for your time,

All help is appreciated.
