We have identified several occurrences of multiple/duplicated ToolBox items existing in the Visual Studio Toolbox. Unfortunately these seem to stem from a glitch in Visual Studio, which was still not reproduced reliably so that we can fix it, or ask Microsoft for a fix.

Below are the different kinds of occurrences and their possible fixes:

    * Duplicate Toolbox items, remaining two entries per control:
          o this could be a result of having parallel RadControls installations, which is the correct behavior (Visual Studio 2008 only)
          o this could be the result of an improper deregistration of an older RadControls distribution, followed by the registration of the newer one. Usually either of the two approaches below helps fixing the problem:
                + Close Visual Studio instances, start Windows Explorer, navigate to %localappdata%\Microsoft\VisualStudio\10.0 and delete the *.tbd files
                + Right-click the Toolbox inside Visual Studio and click Reset
    * Multiple entries per control, number increasing with each start of the IDE: this is the worst scenario we have come across. All the registry entries and files on the customer machine seemed fine in this case. The only fix we were able to apply was a complete uninstall of RadControls and Visual Studio 2010, followed by a clean install of the IDE and the RadControls.

Hi, how can I get screenshot of sparkline?

I do the following:

RadSparklineBase sparkline = new RadLinearSparkline();sparkline.XValuePath = "X";sparkline.YValuePath = "Y";sparkline.Margin = new Thickness(0);sparkline.Width = width;sparkline.Height = height;sparkline.ItemsSource = new SparkPoint[]{new SparkPoint(10, 10),new SparkPoint(10, 20),new SparkPoint(20, 10),new SparkPoint(10, 5)};DrawingVisual visual = new DrawingVisual();using (visual.RenderOpen()){new VisualBrush sparkline);}using (MemoryStream stream = new MemoryStream()){Rect rect = new Rect(0, 0, (int)width, (int)height);RenderTargetBitmap renderTargetBitmap = new RenderTargetBitmap((int)width, (int)height, 96, 96, PixelFormats.Pbgra32);sparkline.Arrange(rect);renderTargetBitmap.Render(sparkline);PngBitmapEncoder pngBitmapEncoder = new PngBitmapEncoder();pngBitmapEncoder.Frames.Add(BitmapFrame.Create(renderTargetBitmap));pngBitmapEncoder.Save(stream);stream.Flush();image = Image.FromStream(stream);}

Is it possible to make it work? Thanks.

There seems to be a bug in the RadGridView. If I select the grid and press the delete shortcut key, the selected row is removed from the grid. If I edit a cell before trying to select a row and deleting it; the delete shortcut stops working (pressing it has no effect). The grid is bound to a BindingList. I have noticed the same effect on two different grids, I've also noticed that if I remove an item from the bound collection, the radgridview updates as expected (its just the delete shortcut which is gone). Is this a known issue, and are there any workarounds for it?

I've also created a custom command provider and observed that the delete command is being created and sent to the grid after the del key is pressed.

Update:

I've managed to reproduce this in a small test project.

This is what I bound to:

    internal class ViewModel
    {
        private readonly BindingList<Item> _items = new BindingList<Item>();

        public ViewModel()
        {
            _items.Add(new Item{ A = "First item", B = "howdy"});
            _items.Add(new Item { A = "Second item", B = "doodle" });
        }

        public BindingList<Item> Items
        {
            get { return _items; }
        }
    }
}

This is the view:

3. Just set the viewmodel as the datacontext for the window upon initialization.

Steps to reproduce (i'm using the wpf q2 2010 sp2 release) :

1. Start test project, notice that you can select rows and delete them
2. Restart test project, double click on a cell to put it into edit mode
3. Go out of edit mode by pressing "escape"
4. Try hitting the del key, the selected row will not be deleted.

I've submitted a support ticket on the issue: 378153

Hi

I have a hierarchy structure like this. Can i use RadTreeList to display the structure. I understand we can SelfReferenceHierarchy feature of RadGridView but is this supported in RadTreeListView

Task 1
    Task 1.1
        Task 1.1.1
Task 2
    Task 2.1

The problem I am facing with RadGridView is that columns are not coming up aligned so i wanted to see if RadTreeListView solves my problem

I have the Q1 2010 Telerik controls.
We implemented the RadSchedulet and I implemented a custom AppointmnetTemplate.
When you move over an appointment an x appears and when you hover over this x it lights up. I want to add an extra button that has the same behavior style wise. but I can not find wich styles are applied to the button and also if I make a copy of the origonal AppointmentTemplate I can not find the button.
Can you give me the Xaml code for the origonal button so I can reuse it?

  Hi

I'm trying to design a full screen interface where static panel with no boundary frames can have a dock panel on the right and on the bottom, but I don't know how to eliminate the header tab in the document pane and eliminate the margin frames.

 Is it possible to create such an interface with Dock Control?

 Regards,

Carlos.

Hi there,

this is a feature request :-)

I would like to have a DataForm control simular to the Silverlight DataForm control which is included within the Silverlight-Toolkit.

While the Silverlight DataForm allows to edit collections, I am more interested using the control for editing a single class/record.
I used the XAML PowerToys (http://karlshifflett.wordpress.com/xaml-power-toys/ scroll down for some screenshots) for a initial layout of a DataForm - would be really helpfull, if I can get something like that for the new WPF DataForm control.

What do you think?

Hello,

My problem is when I undock a RadPane and then I lose my transparent background of the PaneGroup and instead get a white(defualt) background of the floating container that I also want to be transparent.
I wanted to know if there is an event that is fired when a RadPane is being undocked (and the other way around). If there is I could find the floating container and set in code its backgorund to transparent.

Thank you

Hi everybody,

I am using the RadTileView with the RadFluidContentControl. When I have many items in Restored mode, the TileViewItem shrinks itself hiding the content even if I put a fixed Height and Width and I cannot setup the scroll bars in this mode. Is this an issue? How can I do to enable the scroolbars and setup the minimum size for the TileViewItem in Restored mode?
Thanks in advance!

Christian

BTW: I am using the trial version of WPF RadControls Q3.
