Binding ScatterPointSeries.XValueBinding to DateTime

Hi all,

I am having trouble with trying to bind the x-value for a ScatterPointSeries to DateTime variable. The chart is based on live data, so I know that the data binding in general is working because the Y-axis is adjusting correctly. However, no tick marks are showing up for the X-axis, and thus no scatter points are showing up on the graph. Below is the code snippet for the dynamic data binding.

def = new ScatterPointSeries()

{

XValueBinding = new PropertyNameDataPointBinding("Time"),

YValueBinding = new PropertyNameDataPointBinding("Value")

};

...

(def as ScatterPointSeries).PointTemplate = (DataTemplate)System.Windows.Markup.XamlReader.Parse(

@"<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"">

<Ellipse Width=""5"" Height=""5"" Fill=""" + BrushColor.ToString() + @""" Opacity=""" + WPConstants.DEFAULT_LINE_FILL_OPACITY + @"""/>

</DataTemplate>");

Thanks,
Jin

Drag handle disapears

Dragging and dropping works great on my development machine, but when I move the application to a client machine and try to drag, the drag object apears briefly then disapears as I move the mouse. The two machines are running the same operating system. Is there something Im missing to stop this from happening? The only difference between machines is on my development one I have the Telerik tools installed and on the client machine I am running the Telerik dlls from a folder.

thanks for any help,
Bryan

Drag cue offset

Using drag and drop on screen whose display is set to 120 DPI offset the drag cue. The drag cue is positioned away from the mouse and gradually moves further away as the mouse moves around the screen. To reporduce this issue run the drag and drop example in the WPF examples, and set DPI to 120 and see the offset position of the drag cue. Is there a fix for this?

thanks,
Bryan

2.Also want to apply animation on page change(like changes a image from gallery ).
3.Hide the scroll bar from pdfviewer.

How does IsBusyIndicationVisible work ?

I have a situation where I need to know when the RADBusyIndicator is unloaded. The IsBusy is binded to a property 'ShowMessage' and when I do in the code behind:

public void foo()
{
        obj.ShowMessage = false; //Set IsBusy binded property in View Model names 'obj' to false

        while (busyIndicator.IsBusyIndicationVisible)
                { System.Threading.Thread.Sleep(100);}

        //--------- Code to execute after BusyIndicator unloaded
}

However this does not work and code goes into an infinite loop at the while.

Next I executed:

while (busyIndicator.IsBusyIndicationVisible)
                { System.Threading.Thread.Sleep(100);}

        //--------- Code to execute after BusyIndicator unloaded

In a separate thread, but that also does not work which is very strange. I seems BusyIndicator blocks on every access to busyIndicator.IsBusyIndicationVisible property.

Any workaround will be very helpful.

Thanks,
Chait
