Pre-defined Set of XCategory Labels in DataBound Line Chart

My data is structured such that I have 10 categories that I always want to display on the X axis, regardless of whether there are actually points in the bound collection for each of those 10 categories. Is it possible to define a collection of categories that I want displayed on the X axis prior to binding to an actual data source? Then, once the data source is bound, a line can be drawn between the YValues of the points in the categories that are actually present in the chart?

As a simplified example, say I have categories A, B, C, D, and E. My data has values B=10, D=15, E=12. I want to display a chart where all 5 categories are listed along the X axis with a line drawn between the B->D->E values. Is this even possible in a data bound scenario?

RadDocking inside RadTabControl

Hi,



With Q2 2011, it is not possible to drag RadDocking panes, when the raddocking is placed inside 

a radtabcontrol. See code below. I think that this is a known issue.

When do you expect to solve this issue?

In the meanwhile, is there a workaround?



Thanks,

Thomas

Possible bug in Radchart legend?

Hi all,

I have found a strange behaviour in the radchart legend and I'd like to know whether it is due to something I am missing or to a bug.

The scenario is pretty simple. I have a Radchart plotting several line series. Each series's parametrization (color, axis ranges, and so on) is stored in a settings class. As the user edits the series settings, the settings class is updated and changes are propagated to the chart (not via binding but using normal procedural code). The problem comes when the user changes the series color. I then use the following piece of code to change the color in the chart series:

obSerie.TelerikSeriesMapping.SeriesDefinition.Appearance.Stroke = new SolidColorBrush(obSerie.SerieColor);

This works great and the chart series changes its color accordingly. However, the small square in the legend associated to that serie does not update itself and keeps the color previous to the change.

Am I supposed to make any other updates in the control or is this a bug?

SizeChanged not fired and ActualHeight and ActualWidth incorrect

I'm trying to layout my custom RadPane header using events. In the event handler I need the ActualWidth and ActualHeight of the RadPane. However both values are set to 27,96 and 46,65 while the RadPane is much bigger.

I tried using radPane.Measure() to get more actal values, but this does not change the ActuallWidth and ActualHeight.

I Also added a resize event handler to the RadPane, but my eventhandler isn't called when the RadPane resizes, the SizeChanged isn't called when or after the RadPane is resizing. So this makes it very hard to get the actual width en height of a given radPane.

Does anybody have a solution for this?

Error when running application (2011.1.419.35)

Good evening,

I get the following error for the RadRichTextBox when trying to run my application.

Missing Method Exception:
Method not found: '!!0 Telerik.Windows.Controls.DependencyObjectExtensions.GetVisualParent(System.Windows.DependencyObject)'.

I'm not really sure what's going on. I use all of the references that are mentioned in the documentation.
The error is thrown when I click on the RichTextBox and try to type characters into it.

Any help is greatly appreciated. I'm using version 2011.1.419.35.

Thank you very much.

Demo Project Problem

I'm about to use you controls for the first time, I have a few questions;

The examples, is there a copy where you get individual examples? Loading the whole project takes a while.
The example demo does not show the source code correctly, the rendering is all broken, is there a reason for this?

Thanks

Selection Highlight

There is a Selection Highlight that highlights slots in the ScheduleView control; however it doesn't appear to actually select any appointments within the highlighted slots.

I am looking for information on how to use the selection highlight.
