I have a toolbox containing two types of shapes: circles and rectangles.
I create these shapes in code. My viewmodel contains a Geometry property.
The circle I create using the statement "ShapeFactory.GetShapeGeometry(FlowChartShapeType.StartShape)" which gives me a geometry.
This is working fine.

The StartShape geometry has a built in size of 74 by 111 pixels.
Now I find these shapes to big and want to make them smaller. 
It seems I'm not able to change the width and height of the generated Geometry.

I tried setting the width and height in the ControlTemplate but it doesn't give me the result I want because the shape is still to big while dragging the item from the toolbox.
I also tried setting my the Geometry to a new EllipseGeometry. But this gives me an error "Unexpected token 'System.Windows.Media.EllipseGeometry' encountered at position '0'."

Could you please tell me what's the easiest way to use these predefined basic geometries but in a different size?

I have a windows service that periodically sends emails with images of ChartView controls. I am having a hard time getting the ChartView to fully render unless I attach it to a window and show the window and then immediately close it. The code is running from a windows service and so this is really not desired.

 If I render the control using the following BuildContentStream method then it simply displays the "No data to display message"

 

private MemoryStream BuildContentStream(FrameworkElement visualItem, int width, int height)
{
    var view = visualItem;
    view.Measure(new Size(width, height));
    view.Arrange(new Rect(0, 0, width, height));
    view.UpdateLayout();
 
    var rtb = new RenderTargetBitmap(width, height, 96, 96, PixelFormats.Default);
    rtb.Render(view);
 
    var png = new PngBitmapEncoder();
    png.Frames.Add(BitmapFrame.Create(rtb));
    var memStream = new MemoryStream();
    png.Save(memStream);
 
    memStream.Position = 0;
    return memStream;
}

If I attach the control to a window and then do the following then it works correctly.

// The window acts as a visualizer. Can't get it working otherwise
var window = new RadWindow();
window.Height = 300;
window.Width = 400;
window.Content = errorItem.View;
window.WindowState = WindowState.Normal;
window.Show();
window.Close();
 
var stream = BuildContentStream(errorItem.View, 400, 300);

 

I have also tried the ExportToImage extension without success?

Is it possible to get this working from a windows service without any UI?

Hi,

Issue#1

We are using Rad Map control in one of our application where we need to show current position of the device. To achieve the functionality we are using timer to get updated position at regular interval.We are also using VirtualizationSource class to bind data on map (reference  - http://demos.telerik.com/silverlight/#Map/DynamicLayer). But each time when we are binding the data to map control labels showing on the map are blinking. [see img1 & img2 Attached]

So Please suggest some solution for the same.

Issue#2

In above mentioned application, I want to retain the focus area of the Map. How can I achieve the same ?

Please guide.

 

Also, Is it possible to set Width and Height as AUTO of the Labels on the Map.

We are using telerik GridViews, and on the startup of the application we get the following exception thrown. We do not get any stack trace related to our application, so we don't know where to start looking for the source of the problem. It seems that when initializing the grid is some issue, but we don't know what could cause this.

Hi,

We have had a request from a user who asked if we can show the Y-Axis on both sides of a chart. Is there an easy way to do this using your charts for WPF? The only approach to achieving this that I can see is to have two of each series but assign them to different axes. I would prefer not to do it this way if we can avoid it.

Thanks,

Steven

Dear All,

together with the address the Longitude & Latitude should be saved.

I tried to use the AutoResetEvent but it is not working.

After WaitOne() is called, nothing happens. The EventHanlder is never called.

Please let me know if you have an idea.

 

AutoResetEvent waitHandle = new AutoResetEvent(false); 

if (fullAddress != String.Empty && Item.Longitude == 0 && Item.Latitude == 0)
{
    Telerik.Windows.Controls.Map.BingSearchProvider provider = new Telerik.Windows.Controls.Map.BingSearchProvider(bingApplicationId);
    Telerik.Windows.Controls.Map.SearchRequest newSearchRequest = new Telerik.Windows.Controls.Map.SearchRequest();
    newSearchRequest.Query = fullAddress;


    EventHandler<Telerik.Windows.Controls.Map.SearchCompletedEventArgs> eventHandler = delegate(object sender, Telerik.Windows.Controls.Map.SearchCompletedEventArgs e) 
        {
            foreach (Telerik.Windows.Controls.Map.SearchResultSet result in e.Response.ResultSets)
            {
                if (result.SearchRegion != null)
                {
                    Item.Longitude = Convert.ToDecimal(result.SearchRegion.GeocodeLocation.BestView.Center.Longitude);
                    Item.Latitude = Convert.ToDecimal(result.SearchRegion.GeocodeLocation.BestView.Center.Latitude);
                    Debug.WriteLine(String.Format("{0} Latitude:{1} Longitude:{2}", Item.Name1, Item.Latitude, Item.Longitude));
                }
            }

            waitHandle.Set();
        };

    provider.SearchCompleted += eventHandler;

    provider.SearchAsync(newSearchRequest);
    waitHandle.WaitOne();

    Debug.WriteLine(fullAddress);
}

Hi!

I want to display a scale bar (see attached image) in the chart. How can I achieve this?
I don't see an annotation type where I can specify the position in absolute values, but the size in units of the MajorStep.

I need it in both Cartesian and Polar charts.

 

A second question: How can I display a label for a PolarAxisGridLineAnnotation?
