I just started using the RadChart control and am attempting to create an XY scatter chart that displays matrix data that consists of row/column coordinates with a measurement value at each row/column location.  Both the row and column are 1-to-n, so I don't know the upper bound size of each is until runtime.  Here's the class representation of a single datapoint:

This is the method I'm using to create sample data that I am using to test this out with each row/series of data having multiple measurements:

What I am attempting to do is configure the chart declaratively in XAML, but I can't seem to figure out how to get a series for each row this way since it seems as though I need to know how many ItemMappings there will be beforehand.  Here's the XAML I started with for the chart:

This results in a single series for all of the data.  Is there some way of doing this declaratively so it will know to create a SeriesMapping for each row of data that I have?  Here's the solution I came up with using the code-behind, but I would much prefer to do it declaratively in XAML if it's possible.


I've included the image of what the graph looks like if it's of use. Thanks a lot for any suggestions.

I do not seem to be able to do it in WPF (in Silverlight it works fine).
Moreover, whenever I have an open popup (not for drag and drop), if I hover the mouse over it while doing a drag-and-drop operation the position of DragCue changes.
What do I do to get around these problems?
If I cannot use the WPF popup, are there any similar Rad controls that I can use instead?
Also I was trying to use RadWindow instead of a popup (even though popup is actually what we need) and it did not event allow me to drag the DragCue into it.
Please Help!!!!
Thanks

We started to use the Telerik version 2010 3.1314.40 dll's.
Now we get errormessages which we didn't have had before.
We just open a window with a RadMap connected to a mapsource.
After a bit paning, zooming and waiting we get this message:

Hi,
i am using RadGridView  i have a toggle button in one of the grid column, my question is when window loaded i need to set the togglebutton.ischecked to true,  when i am trying to loop to the grid i am getting only the first page rows, how can i get all the grid rows.
i have 200 records

 IList<GridViewRow> rows = radGridView.ChildrenOfType<GridViewRow>();
            foreach (GridViewRow row in rows)
            {
                if (!(row is GridViewNewRow) && !(row is GridViewHeaderRow))
                {
                    GridViewToggleButton toggleButton = row.Cells[0].ChildrenOfType<GridViewToggleButton>().FirstOrDefault();
                    if (toggleButton != null )
                    {
                        toggleButton.IsChecked = true;
                    }
                }
            }

thanks

I recently updated to the Assembly version was 2010.2.812.40.
Use this code in the updated version, there is a problem.

First, RadTimePicker Dropdown Item When we do not display properly spaced
This was resolved by specifying ClockSyle. In previous versions, but was not required to specify

<telerikInput:RadTimePicker Culture="en-US" Style="{StaticResource ui_TimePicker}" ClockStyle="{StaticResource ui_Clock}"/>

Second, RadComboBox changes in the selected index when using DataTrigger RadTimePicker tries to change the value of the TimeInterval.

In previous versions of normal, respectively. However, the updated version does not change the value.
Which part is the problem, but I do not know many tests.

To using this code is wrong? Or, there is a problem with the updated version?

I can not find the correct answer, writes Thread.

Wait for an answer. Thanks.

Hello,
I have  problem with FilteringControl:
I want to limit the size of ListBox with CheckBoxes, I managed to limit the FilteringControl But I failed to limit the
ListBox with CheckBoxes Inside FilteringControl.
Property MaxHeight and MinHeight Working on FilteringControl.
the code:
<Style TargetType="telerik:FilteringControl">
     <Setter Property="MaxHeight" Value="350"/>
     <Setter Property="MaxWidth" Value="300"/>
     <Setter Property="ScrollViewer.IsDeferredScrollingEnabled" Value="true"/>
</Style>
Thanks for your help,
lisa.

First of all, great work on the RadRichTextBox! I'm planning on using the RichTextBox in an application that will share a single RichTextBoxRibbon with several RichTextBoxes. I was wondering what would be the best way to dynamically bind the RichTextBoxRibbon to a specific RichTextBox.

Thanks,

Will

I've got a hybrid Chart where the high-level definitions are in XAML, but I build the DataSeries at run-time.  I'm getting a case where I have a Legend on the right, but there are no entries there.  Here's the XAML:

Here's the code-behind that populates the chart via a non-default constructor on a Window:

Some of the high points:

• As you see in the XAML, the ItemsMapping is pointed to the DataContext of the Window
• The DataContext is Collection<LoggedACMeterData>
• A LoggedACMeter object has, among other properties, a DateTime Timestamp, a double WattsAllPhases, and a Circuit object which has a String Name property.
• At the moment, the dateRange is ignored.
• I hand in the IEnumerable<Circuit> to the constructor with the idea of building a DataSeries for each Circuit.
• To do the above, I use the ChartFilterDescriptor on each DataSeries to only pull records from the DataContext that matches the circuit name.

So the grid is getting set up properly, with the X-Axis correct, ane the Y-Axis labelled properly, and multiple color-coded series.  But the Legend is empty.  Thoughts? 

Attached is a screen shot of what I get.

 (on edit: I guess I really mean a SeriesMapping, not a DataSeries as described above)

Hi!


I'm having my UserControl to show Thumbnails (list of images) using transition control. Image changes one to another every 7 sec. and to achieve this I'm using a Timer. Next is a snipped code:


First image is showed fine, but when timer elapsed is reached, exception is thrown when try to change to another transition effect. Error is:
"The calling thread can not access this object because the owner is another thread". How can I do to achieve this thumbnail???


thanks
