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!

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

I create my chart by inserting data points like so:

The points themselves are created thusly. I explicitly specify types for your convenience.

When I call the add method, I obtain the graph (supplied) "mychartnormal.png". I'm happy with this graph.

When I do the following manipulation of the graph, I obtain a new figure (supplied) "mychartweird.png". The number formatting of the highlighted values shows unnecessary precision. 

You may wonder at this point why I am not manipulating the Definition.Appearance.Fill property of the series that I pick out on line one directly. Well, the reason being is that I want to the drawing animation to restart, and I didn't find another way in the API do that. As such I am open to two possible solutions.

Firstly there's the obvious rewrite that solves the problem, but I find it in bad taste to have to recreate the series, since I may need to modify other properties separately, and the copying on line 3 can easily become unwieldy.

Secondly all I really need is to restart the animation. I only found one relevant post, which said to use Chart.ResetTheme(), which didn't work for me.
