Hi Telerik,

I'm trying to retrieve the date of which I have right-clicked.
How can I retrieve a date (in month view) from a given point in the calendar.

Or if it is possible to have right-click also select the date would help me.

What I'm trying to achieve is that I have added a context menu and need to display some checked menu items according to the date being right-clicked (not the selected date).

Thanks in advance!
Best regards,
Kasper Schou

RoutedCommand and floating Pane

Hi,

I'm in this simple situation, my Shell contains 2 regions
in the first region I have a botton with a RoutedCommand associated (RoutedMyCommand)
in the second region I have a RadDocking like this :

<telerikDocking:RadDocking>

<telerikDocking:RadDocking.DocumentHost>

<telerikDocking:RadSplitContainer>

<telerikDocking:RadPaneGroup Regions:RegionManager.RegionName="Body" >

</telerikDocking:RadPaneGroup>

</telerikDocking:RadSplitContainer>

</telerikDocking:RadDocking.DocumentHost>

</telerikDocking:RadDocking>

when I activate a new View ( a new RadPane ) in Body region, the RadPane is initially "Tabbed Document" and it handle correctly the RoutedMyCommand
when the RadPane becomes "Floating" the RoutedMyCommand is not handled by View.

Telerik version 2010.3.1110.35

Thanks, Andrea.

Hierarchical RadGridView Slow Details Expansion

Hello,

I set up a simple WPF window with two grids side-by-side: A Telerik RADGridView and a Microsoft DataGrid. Both grids are set up with 2 levels of hierarchy (master-detail), and are bound to the same data (2 master records, each with 1000 detail records). Both grids have one fixed-width column on the master and detail levels.

On my machine, when I expand a master row on the Microsoft grid for the first time, it takes 4 seconds to display all the details; expanding a master row on the Telerik grid for the first time takes 9 seconds to display the details.

The thing that appears to be taking a long time is rendering the detail rows -- if I limit the height of the detail grid to 200 pixels, it takes less than a second to expand a master for the first time (this is the case with both the Microsoft grid and the Telerik grid).

I reviewed the performance tips/tricks. Is there anything else I can do to reduce the time it takes to expand a master for the first time in the RADGridView?

Any help is much appreciated!

Here is the XAML and code-behind I'm using:

<Window x:Class="MasterDetailPerformance.MainWindow"

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

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

Height="360" Width="760">

<ColumnDefinition Width="369" />

</Grid.ColumnDefinitions>

<StackPanel Grid.Column="0" Margin="10" Height="300" Width="350">

<telerik:RadGridView x:Name="TelerikMasterGrid" AutoGenerateColumns="False" ShowGroupPanel="False">

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView>

</StackPanel>

<StackPanel Grid.Column="1" Margin="10" Height="300" Width="350">

<DataGridTextColumn Binding="{Binding Name}" Width="200" />

</DataGrid.Columns>

</DataGrid>

</DataTemplate>

</DataGrid.RowDetailsTemplate>

</DataGrid>

</StackPanel>

</Grid>

</Window>

public partial class MainWindow : Window

{

private IList<Master> masterList = new List<Master>();

public MainWindow()

{

InitializeComponent();

FillMasterList();

TelerikMasterGrid.ItemsSource = masterList;

MicrosoftMasterGrid.ItemsSource = masterList;

}

private void FillMasterList()

{

for ( int index = 0; index < 2; ++index )

{

masterList.Add(

new Master()

{

ID = index,

Name = index.ToString(),

Details = GetDetails()

} );

}

private IList<Detail> GetDetails()

{

IList<Detail> details = new List<Detail>();

for ( int index = 0; index < 1000; ++index )

{

details.Add( new Detail() { ID = index, Name = index.ToString() } );

}

return details;

}

public class Master

{

public int ID { get; set; }

public string Name { get; set; }

public IList<Detail> Details { get; set; }

}

public class Detail

Capturing Keystrokes (ctrl,shift) on Grid

Hello,

I need to capture the ctrl and shift keys after selecting a row on the grid. I can code something using the SelectionChanged and keydown events but it will take a while to perfect. Has anyone already coded this logic?

Thanks

DefaultImagesSrc image sizing problem

Hello.

I'm adding an image to my treeview using the "DefaultImagesSrc" property and the ImagesBaseDir property. The image displays, but significantly smaller than it should. I tried setting the height and width properties for the radtreeviewitem to be the size of the image but that didn't work. When I drop an image control onto the xaml and set it to the same image, it displays in the proper size. What am I doing wrong?

<telerik:RadTreeView Height="250" HorizontalAlignment="Left" Margin="12,32,0,0" Name="tvDirectories" VerticalAlignment="Top" Width="364" ItemsSource="{Binding ElementName=radTreeView1, Path=Background}" ImagesBaseDir="/UploadDocFromPDFWPF;component/Images/" ItemPrepared="radTreeView_ItemPrepared">

<telerik:RadTreeViewItem DefaultImageSrc="mycomputer.png"></telerik:RadTreeViewItem>

</telerik:RadTreeView>

Again, if I create a standard image control and use the same image it displays using the proper size.

RadTileView scroll and size issues (?)

Hello,

I'd like to have a few questions about RadTileView WPF control:

I need to change the size (height) of RadTileViewItem. Setting height works fine, but the area provided by owner RadTileView remains unchanged. Is there any way to change this area's size?
The mouse scroll wheel doesn't work with RadTileView placed in ScrollViewer. I haven't found any suitable property to fix this, is there one?
When I have RadTileView placed in ScrollViewer, I scroll down little bit, click any focusable control contained in a child RadTileViewItem, and then it scrolls itself the top of the RadTileView. (In other words, when any control on RadTileViewItem gets focus, it automaticaly scrolls up to RadTileView's top border). Is there any way to change this behaviour?

Thanks for every answer.

Dynamic DataTemplates

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding PatientName}" Width="125" Margin="14,0,0,0" />

</StackPanel>

</DataTemplate>

<DataTemplate x:Key="MaximizedHeaderTemplate">

<StackPanel Orientation="Horizontal">

<TextBlock Text="{Binding PatientName}" Width="125" Margin="14,0,0,0" />

<TextBlock Text="{Binding Age}" Width="30" Margin="14,0,0,0" />

<TextBlock Text="{Binding Protocol}" Width="100" Margin="14,0,0,0" />

<TextBlock Text="{Binding Actions}" Width="65" Margin="14,0,0,0" />
