Hi,
I am new to the RadRadialGauge,

I tried to create a Radial Gauge like explain in the site.

i have added the two dll:

• Telerik.Windows.Controls.DataVisualization.dll
• Telerik.Windows.Controls.dll

and the namespace:

xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"

my xaml look like this:
<Window x:Class="Guage.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        Title="MainWindow" Height="350" Width="525">
    <Grid>
        <telerik:RadRadialGauge x:Name="radialGauge"
                        Width="300"
                        Height="300">
        </telerik:RadRadialGauge>
    </Grid>
</Window>

I am getting an error when i am compiling the project:
"The tag 'RadRadialGauge' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'. Line 7 Position 10."
"The type 'telerik:RadRadialGauge' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."

What am i doing wrong?
Thanks,

I'd like to group some properties in one node with general name. I do e.PropertyDefinition.GroupName = "Name" in AutoGeneratingPropertyDefinition(), but... nothing!

Can you write code of sample?

My application will be running on a laptop with a touch screen, which will be mounted in a police car and used by the officer while driving.  To make things easy on him/her, I'm making the controls large so they'll find the fingers of people with sausage fingers, like my own.

I'm using a MaskedDateTimeInput control on one screen for entering a TimeSpan.  This is going inside of a UserControl with two large RepeatButtons, one with an arrow pointing up and one with an arrow pointing down.  The idea is that the user will tap the screen in the MaskedDateTimeInput control, say in the seconds area.  The user can then tap or hold the RepeatButton with the Up arrow and I want the MaskedDateInput control to treat it as though the user had pressed the up arrow key on the keyboard.  The same goes for the RepeatButton with the down arrow acting like the user had pressed the down arrow key on the keyboard.

How can I get this functionality to work?  There must be some kind of a WPF command defined by the control but I don't know where to find it. 

Also, is it possible to specify how much one press of the up or down arrow key will change the value of the part of the time span it's in?

Hi guys,

I have the latest production version. I'm applying styles with (for example):

Telerik.Windows.Controls.StyleManager.ApplicationTheme = new Telerik.Windows.Controls.Office_SilverTheme();

However this seems to only change my RadGridView. Everything else is default.

If I go into my Telerik installation folder, there's the handy sample project with all the xaml for the themes. I notice that these include styling for standard windows controls, so why doesn't it work?

And as a side issue, how come most of the sample theme xaml files are missing for Office Black?

Hi There,

I am having quite a baffling issue and I am wondering if anyone can help. I am using a trial version of 'RadControls for WPF Q2 2011' in my WPF application, but every time I try adding a RadChart to my UserControl, it gives me the following (quite unexpected) error:

NotImplementedException was unhandled by user code
The method or operation is not implemented.

Can anyone offer any help with this one? Why would it throw a NotImplementedException?

FYI, I am also using Prism and MEF.

Hi guys,

 

I’ve developing using RadControls for WPF Q3 2011 SP1 (part of the Premium Collection) and looking specifically at the RadWindow control. I like the changes you’ve made over the last few releases but I have a few questions:

 

• The fade in/fade out animation looks good when executed both as a WPF Windows app and as an XBAP run in IE (full trust) however do you provide alternative animations? I’m trying to implement something along the lines of the window width & height starting of as zero in size and then the RadWindow resizes from the centre of the screen when shown - Hope that makes sense. Can you suggest something/perhaps provide an example how this could possibly be acheived?

 

• The ModalBackground property seems to only work when running via an XBAP, is this deliberate? I have all code in a common class library and when called from an XBAP the ModalBackground property takes effect when the RadWidow is shown however, from a Desktop WPF application it seems to have no effect. Am I missing something?

 

• Although the RadWindow is customizable I may need to customise it further by modifying the DocumentTemplate. I have no idea how to do this and looking through your online help I couldn’t find an example. Can you oblige?

 

Thanks

Mike.

Hi, Are there any examples in the documentation which show how threading with the Chart works?

Specifically, my issue is that I have a long loop which adds "Coordinate" objects to an ObservableCollection which is set as the ItemsSource of some ScatterSeries. Assume that this loop takes minutes to complete, as I add a Thread.Sleep(1000) for each iteration. Importantly, I would like the chart to display each "Coordinate" object as and when it is added to the ObservableCollection, without seizing up the whole chart.

I have followed some examples of creating a Dispatcher, however this appears to have no effect. Example code of what I am trying to achieve:



Thanks for any help in advanced!

How would one set the theme (to metro) of a context menu programmatically?

Many thanks.

We're evaluating the RadControls for use in our software, but are running into a bit of a brick wall with GridView. Our software allows the user to click items, then display data about them in the GridView. Each item that is chosen must refresh the grid, add new columns and rows, because the number of each required can vary. Every time the ItemsSource of the GridView is set, the memory used by the program shoots up 10meg or more, even though there are only a few rows being loaded in. 

Any thoughts? The controls in general seem good, but this is unfortunately a deal breaker if we can't get it to work...

We're running .NET 4.0 (C#), Win 7, 2011 Q3 RadControls Trial

Hi, 

I have a radgridview binded to a data-table. I need to make the first column of this grid Combo-box. I have tried the following and it did not worked out well as the combo-column is not showing the data-table data.
My code behind,

My XAML,

I have attached the output I'm getting. 

I need to retain the value selected in the combo. replacing the original content.
 
regards,

SK
