I am trying to export my WPF chart control to an image but I am getting an exception saying "Object reference not set". I am wondering what I am doing wrong here.
I am trying to export to xps. 
My another requirement is to convert to jpeg.
Can you guys please help me doing this?


SeriesMapping sm1 = new SeriesMapping();
sm1.SeriesDefinition = new LineSeriesDefinition();
sm1.LegendLabel = "Line Series 1";
sm1.CollectionIndex = 0;
ItemMapping im1 = new ItemMapping();
im1.DataPointMember = DataPointMember.YValue;
sm1.ItemMappings.Add(im1);
SeriesMapping sm2 = new SeriesMapping();
sm2.SeriesDefinition = new LineSeriesDefinition();
sm2.LegendLabel = "Line Series 2";
sm2.CollectionIndex = 1;
ItemMapping im2 = new ItemMapping();
im2.DataPointMember = DataPointMember.YValue;
sm2.ItemMappings.Add(im2);
var itemsSource = new List<double>[] { new List<double> { 9, 2, 3, 4 }, new List<double> { 5, 7, 3, 4 } };
this.RadChart1.SeriesMappings.Add(sm1);
this.RadChart1.SeriesMappings.Add(sm2);
this.RadChart1.ItemsSource = itemsSource;
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.DefaultExt = ".xps";
string fileName = string.Empty; 

if (!((bool)dlg.ShowDialog()))
{
fileName = dlg.FileName;
}
this.RadChart1.ExportToXps(fileName);

Ok, i have a RadTreeView with an Item Source of List<ActivityControl> which is a user control that has a text box, a canvas and a text box in it... my problem is that because the text box is within the RadTreeView whenever i try and click and drag to select text it tries to drag and drop the Selected item!?! this is going to be a pain for users to try and edit text if they cant drag to highlight....

i've uploaded a video to give you an idea!

http://www.screencast.com/users/kevinrhynas/folders/Jing/media/8fb40a9e-c5ce-4c6f-83ba-20054a6d466f

Also on a side note... i pressume that it is the header of each RadTreeItem that sets the "preview" in the draggable bit... how can i set this if i've simply set the "itemsource" to be a list.. as opposed to manually adding these items??

Dear Team ,
                  Please see the attached image file showing items in the tileView.When i add more items and the items in right side gets so small even i cant see the maximize,minimze buttons . any solution

Kind Regards

I don't see a RadTreeListView forum yet, so I'm sticking this here.

I have a list of objects of type SkuForecast.  Each SkuForecast has a list of objects of type SkuForecastArchive which has the same columns as the SkuForecast.
I'm trying to setup the RadTreeListView control to work with them, but I'm getting an InvalidCastException error cannot cast type SkuForecastArchive to type SkuForecast

What am I doing wrong?

How can I expand a row that has hierarchical data by doublecliking on the row (row with "+" sign)

How do I remove the "+" sign (if possible to expand with doubleclick)?

How do I replace the "+" sign with my own icon?

From what I can tell, the RadCarousel control is the desired control to use for using DataBinding. However, my particular need requires theuse of RadCarousel. Do you have any suggestions to do DataBinding with theRadCarouselPanel?

Thanks,
