Hello,

I associated a contextmenu with a text box.. When "RightClick" on it, the contextmenu opens correctly as expected. I would like to open it in code-behind, let's say when user type CTRL+SPACE for instance or when the user clicks a button beside the textbox.

How to achieve this with radContextMenu?

Thanks in advance for your answer.
regards

GetClickedElement is null in unpinned RadPane

According to the documentation here, to get the RadTreeViewItem so that you can dynamically set the context menu, you need to add a handler for the Opened event and retrieve it like so:

RadTreeViewItem item = ((RadContextMenu)sender).GetClickedElement<RadTreeViewItem>();

We have an application using RadDocking with the RadTreeView in a RadPane. It works with the pane pinned but if I unpin the pane and right click, GetClickedElement returns null. Here's some simple XAML to recreate it:

<Window x:Class="DockingTreeViewContextMenu.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"

Title="MainWindow" Height="350" Width="525">

<Grid>

<telerik:RadDocking>

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadDocumentPane Header="Content"></telerik:RadDocumentPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadPane Header="Pane 1">

<telerik:RadTreeView>

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu Opened="RadContextMenu_Opened">

</telerik:RadContextMenu>

</telerik:RadContextMenu.ContextMenu>

<telerik:RadTreeViewItem Header="Item #1">

<telerik:RadTreeViewItem Header="Item #1.1"></telerik:RadTreeViewItem>

</telerik:RadTreeViewItem>

<telerik:RadTreeViewItem Header="Item #2" />

<telerik:RadTreeViewItem Header="Item #3" />

</telerik:RadTreeView>

</telerik:RadPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

</Grid>

</Window>

So if I slide out the pane and right click the tree node, I get a null result whereas I get the RadTreeViewItem when the pane is pinned. I'm I using the control incorrectly?

Docking RadDocumentPane Header flickers

Hi guys n gals,

I have a RadDocking control...

<telerik:RadDocking Grid.Row="1">

<telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer>

<telerik:RadPaneGroup>

<telerik:RadDocumentPane Header="{Binding Path=CurrentInstance.Name}" CanUserClose="False">

<View:InstanceEditorView />

</telerik:RadDocumentPane>

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking.DocumentHost>

...

</telerik:RadDocking>

...

The InstanceEditorView is basically a StackPanel with 3 GroupBoxes stacked vertically.
Each GroupBox has a few RadMaskedTextBoxes (to provide just Watermark functionality).
When I mouseover the RadMaskedTextBoxes the RadDocumentPane flickers between the RadMaskedTextBox's hover and normal states (ie same colours - hint?).

I am using the Q1 2011 SP1 build and the ExpressionDark theme.

Any ideas how I can get rid of it? Not really very keen on restyling the RadDocumentPane Header...

GridView with Multi Source

Hello,

Can you please tell me, how to bind the two types of object details in the Grid View using Data Table as ItemsSource?

For example:

I have a Class A which has property A1, A2 and Class B which has property B1 and B2.

public class A

{

public string A1 { get; set; }

public string A2 { get; set; }

}

public class B

{

public string B1 { get; set; }

public string B2 { get; set; }

}

I would like to display all the properties from Class A and one property (i.e. B1) from Class B as shown in below.

//======================

// A1 | A2 | B1

//======================

// a1 | a2 | b1

How could we achieve this without creating View Model?

Thanks,
Thanga

Loosing Selection in CollectionViewSource

I have an applicaion with 1 to many tabs that are in viewModel to view fashion with the ViewModels contained in a CollectionViewSource. This works great for other controls that I can start an edit, switch tabs an retrun with edits in place. The gridView is not maintaining selection, sorting or filtering (I believe because it is reinitializing) when the tab it is contained on looses and regains focus.
The grid looses filters, sorting and selection.

FrozenColumnCount Problems.

Hi
I am having some problems with the TreeListView when using the FrozenColumnCount property.
The column header does not align with the cells, ie. the cells take up more space than the header.
Looks like this ascii :)

| Header |
| Cell |

Any idea what is causing this. I'm using the Official Q1 2011 Release.

Best regards
Kristján.

Drag and Drop and SchedulerDialog

Hi there,

I have the following problem with ScheduleView and Drag and Drop. As recommended, I implemented a custom DragDropBehavior class that inherits from DefaultDragDropBehavior. In here everything works fine. After the "public override void Drop(DragDropState state)" method was called, the new created appointment is passed to the AppointmentCreating event of the ScheduleView. My Problem is that I want to show the scheduler dialog as it would happen if AppointmentCreating event was produced by a doubleclick. Instead of showing the dialog the AppointmentSaving event handler is called immediatly. How can I achieve it that the dialog will be shown? Since I have different IResourceType objects in my scheduler I need the dialog to give the user the possibility to set them correctly.

thanks in advance,

michael
