I'm trying to style my Y-Axis striplines (eventually to be bound), but I can't seem to do so correctly. Declaritvely, I can set a single chart's ChartArea.AxisY.StripLinesVisibility to Collapsed, but everything I have tried makes it seem as if these guys were impervious to styles. So basically: how to:
  * Declare the style correctly in XAML
  * Set the style correctly in C#, at the time of Chart creation (I must do it like this, as the charts are created at run time)

Currently, I have in my XAML:

and where I'm creating the chart I have

Hello,

I have a window with a RadToolbar and a button in this toolbar :

All works fine, my button looks like a toolbar button (no border, no background).

But if I put a style on my button (even if the style is empty) :

my button looks like a normal button (with border and background).

Is there a workaround for this issue ?

Thank you.

Hi,

Hi!

We are experiencing serious performance issues using the RadChart as the number of series increases.  At times we receive a Stack Overflow exception from with the charting code.  The problem appears to be related to using a Categorical X-Axis.  For a Categorical X-Axis it appears that the chart loading time increases exponentially as the # of series increases.  Using a Numerical  X-Axis does not cause a problem and the load time increases linearly as the # of series is increases.

I created a simple example application that charts a bar series.  With only 3 Points per series the load times were as follows:

100 Series (300 total points): 3.4 sec
200 Series (600 total points): 13.9 sec
400 Series (1200 total points): 57.5 sec
800 Series (2400 total points):  Stack Overflow exception

As the series count doubles the load time increases 4X.  As a comparison, 1200 points in 400 series takes 57.5 sec, but the same number of points in only 1 series (1200 points) plot  < 1 sec.

Using a numerical X-Axis the 400 Series x 3 points plots in 10 sec.

I have turned animations off, and data sampling will not help since the problem occurs with very few points per series.

Looking at the call stack during the exception the problem appears to be causes during processing of the categories for the X-Axis.  For the above examples the were only a total of 3 categories on the X-Axis.

I am also submitting a support ticket with a sample application.

I have decided to go away from xml databinding and instead use object databinding because of the advantages you get using OnPropertyChanged.  The easiest way to get this done is to create a xsd of your xml and then use a program called Xsd2Code to have all your properties contain OnPropertyChanged.

Hi guys,

I have found this article http://www.telerik.com/help/silverlight/gridview-how-to-create-external-filtering.html
which explains how to do nice external custom search on all the columns of the grid.

In that example it is convenient that all of the columns are strings which makes the problem a little bit easier.

In my code most of the columns are strings but I also have some that are DateTime, enums (status fields), and integers.

I know how to exclude these columns from participating in the search but that is not acceptable solution. I need to be able to search all the columns regardless of the input.

Is there a way to set all of the columns to be of type:String for filtering function (but for sorting they need to be of the correct type DateTime, int, etc)?
Any suggestion on how to solve my problem are helpful.


Thanks,

Hi.
I'm using the latest (I believe it's 2010.1.603.35) version, and found if I put TickLineStyle on Y Axis (I just changed the color) the ticks of X Axis all go funny - They lean horizontally.

I need to make the axis lines and tick lines white.
Is there a way to fix this problem or any other way to make them white rather than using the styles?

Hi,
I'm using TreeView with the checkbox enabled


So the basic usage:
The treeview has no checked items to begin with and is collapsed. The user should be able to check the top item.

So the problem is that I cannot iterate through the checked item collection when the tree is collapsed because the items do not exist.
Is there any way to have the items created so I can iterate through them without expending the tree.

Best regards
Kristján.

Hello,
When I use RadAlert in windows7 I found that it can not show correctly except some fonts, just like the visibility property is set to hidden, is there any way to solve this problem?
thank you!
