Binding RadDocumentPanes to a collection

We are trying to bind a collection of items to a set of RadDocumentPanes through the ItemsSource & SelectedItem properties on the RadPaneGroup control. Unfortunately we were unable to create viable documents in this manner, and had to create a custom converter to return our items wrapped as RadDocumentPanes. Is this a limitation of the Rad control or is there a better way to do this?

Removing Windows Form Controls?

In the attached file it shows the original Windows control bar (that has the minimize, maximize, close) still remains on the RadRibbonView. Also, there is a forward and back navigation bar, I'm not sure why; so, how can I remove these and place the buttons on the ApplicationName bar? Source Code:

<telerik:RadRibbonView x:Class="Magnetek.Network.Client.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"

xmlns:ribbon="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.RibbonView"

MinHeight="100" MinWidth="200"

x:Name="RadRibbonWindow">

</telerik:RadRibbonView>

Also, with Windows Ribbon control I can start my window in a certain position using:

WindowStartupLocation="CenterScreen"

Is there a way to set the startup location and start the application maximized?

Delay when using EntityFrameworkDataSource

Hello!

In our WPF project, we have a UserControl with a RadGridView to display persons. We decided to use the EntityFrameworkDataSource because it is easy to implement and offers a lot of advantages.

We implement the Entity Data Source and everything is working except one thing. When we click on the Menu to call the UserControl, a delay is occuring. the UserControl takes 5~10 seconds to appear, and when it appear the RadGridView is already loaded with the data.

If i remove the lines of the DataSource, the UserControl loads fast with 2 seconds. The Gridview only has 20 itens, i'm afraid that when the data begins to grow this delay became worse, it will impact a lot for the client.

Can you help me solving this? It is hard to explain with words, if you not understand the problem let me know and i try to make a video.

Thanks!

TrackBall Memory Leak

I have an application with potential thousands of views (as radpanes with a single usercontrol) and therefore need to make sure they can be cleaned-up, when they are not needed anymore.
I had some trouble with the radpanes, but eventually got it working for most of my views.

However I have run into problems with views containing charts.
What I have come up with is that the trackball keeps a reference to the usercontrol containing the chart. So while I manage to get rid of the radpane, the usercontrol is beeing kept in memory.

With a memory-profiler I have found out that the offending class is Telerik.Windows.Controls.ChartView.DataPointInfo, which apparantly has some valueChangedHandlers that are not cleaned up.

I have given up trying to clean these up myself, so I really hope you have a fix for this in the works.

Is this something you are working on?

Best regards

Mask with ANY number of digits

I'm using RadTextInput and I want to specify the number of digits after comma, not before it. E.g. only two digits after comma should be allowed, but ANY number of digits before comma. What mask do I need for this?

Mask like "#.2" displays 123.12 as 3.12

In the ElementLoaded IsFloating is not filled correctly

My application saves the layout when exiting, and restores the layout when starting.
The specs tell me the restored layout has to be exactly the same as the layout when exiting the application.

For floating panes the size of the restored layout is incorrect, it is the size with which the pane was created, not the last size.
I think this is a bug.

To fix this I store the size of the pane myself when exiting the application, and try to set it in the ElementLoaded Event whens starting again. However only Floating panes should get the size they had before exiting the applications, the other panes are in the RadDocking layout and sized correctly.

The problem I'm facing is that the IslFloating property of floating panes is false in the ElementLoaded. So I can not detect which panes are floating. This is the second bug I think.

Does anyone have a clue how to solve the problem of the incorrect size of the restored pane?

Header Text Left & Right

I want my context menu item to have Text on left and keyboard shortcut on right. I dont want to give fixed width as my Text size can increase/decrease based on localized string

I tried putting Grid but the Width of the Grid is not getting 100% of the Item.

<telerik:RadMenuItem>

<telerik:RadMenuItem.Header>

<Grid >

<Grid.ColumnDefinitions>

</Grid.ColumnDefinitions>

</Grid>

</telerik:RadMenuItem.Header>

<telerik:RadMenuItem.Icon>

</telerik:RadMenuItem.Icon>

</telerik:RadMenuItem>

Is there any way we can add additional column to context menu item just as image column so it always come on right seperate from header?

Or is there any solution to this problem?

Metro App with WPF

Hi,

I would like to know if Telerik plan to develop "RadMetroControls" in order to simulate Metro App also on Windows 7.

I've seen that you have developped something for WinForms (DemoHub), but some features are missing (such as application bar, ...).
Currently, some projects are available on Codeplex (http://mosaicproject.codeplex.com/, http://newgen.codeplex.com/).

Do you plan to develop such controls/framework and integrate it into the WPF package for this year ?

Thanks in advance

Patrick
