Hi there, 

Currently I plan to use TreeListView in our application. We have resource directory to control the look and feel of our application. How can we apply this look and feel to your TreeListView?

Example of the theme that we want to apply is to set the background color of the selected row as well as the TreeListView table header.

Can ChartView do these things? 

Mouse-over selected series in series list changes contrast of selected series via data binding so that selected series is clearly visible and other series are faintly visible

Mouse-over chart coordinates shows tooltip(s); if multiple series are involved, tooltips arrange themselves in a smart way

Hi Telerik
In a usercontrol, I have this property in the code behind:

 

 

In xaml, the usercontrol have the name: x:Name="This"

Could you somehow, please help me to get MyText into the header in the menuItem?- the following example, is not working for me: 

 

Thanks from Kenneth :o)

 

 

 

Hello,
using a RadRichTextBox I am facing the following:
Document is not in readonly mode -> Cursor is visible, can be moved via mouse and keyboard = > okay!
Document is in readonly mode -> Cursor is not visible, but can be moved via mouse and keyboard and shows up on a not expected postion when the document comes back to an editable state again. What can I do against this behaviour?

Another question I have: Is it possible to keep an selection made while in an editable state, but do not permit selection while in "readonly" (setting "isSelectionEnabled" to false)?

Thanks in advance

Hi guys,

I am struggling mightily with the new ChartView controls. The documentation is severely lacking. I'm trying to use the new RadPieChart and the examples show only the bare minimum. I've looked at the demos - again, simplistic. Where does one add something simple like a chart title? How do you create a legend outside the chart area? The demos show hardcoded values and hardcoded mappings, but in practice this is never the case.

The old RadChart control is well documented, so perhaps it just reflects the newness of the new DLL.

is there an updated CHM? More realistic examples? The online docs are still almost completely silent on RadPieChart and google searches ALL relate to the old RadChart control.

Hi in my wpf application i want to plot two line chart..

and my requirement is i want to show each point in line pointmarker in different color.

i achived this for single line chart, when i try for two lines, both taking the same point mark fill color..

how to resolve this problem.. i am using item series mapping... 

Hello In my wpf application my requirement is to plot a two line graph with different color of point markers..
 i achived colours for point marker foor single line graph. but if try that method for two line graph am not getting result. am getting single line only,, 

Am getting double line if i use dataseries . but i need to do that by item series,,,

My values are from single tabel, two different columns....

Hello,

i use RadExpander with theme Expression_Dark. It looks like that, the style of header has been set to standard style. So the header text is black. It will not be seen easily. Have you resolved this problem? Or that is just so specified ;)

Thanks.

Hi everyone,
I can export the whole map image file now using the code below.

But the problem is that I have added a few marks on radmap information layer.
How to export these marks together with the map image?

I have a gauge that has a smaller Min and Max than the allowed values for my needle binding. For instance I have my Min set to 20 and my Max set to 80. The valid range is actually 0-100. 

The needle therefore goes outside of the gauge. Other than putting a valueconverter on the needle value to stop this behaviour is there any built in way I've missed to limit the needle?

Note: The bound property is used elsewhere, where the actual upper and lower limits are valid, so I can't limit it in the class. The only other way I could think of is to create a separate property that does the limiting in the class and then bind to that instead, which I guess would be better performing than a converter.

Thanks...
