Hi,

Can we create our own controls like Rectangle, Ellipse and add them to the Rad Diagram for performing all the functionality which are supported by Rad Diagram?

Please send us example. I need to add Rectangle to the Rad Diagram and need to change its color, size... How to do that???

To dynamically get control I used below code:

RadDiagramShape shape=new RadDiagramShape();

shape.Geometry= ShapeFactory.GetShapeGeometry(CommonShapeType.RectangleShape);

raddiag.AddShape(shape);



foreach (RadDiagramShape sample in raddiag.Items)
                {
                sample.Background  = newBrush;
                }

And used the foreach loop to get the control and apply color... but we are not able to get any item in raddiag.Items it is showing null.. what we are missing here???? please let us know...

Keenly waiting for reply...

Regards,
Swati

Display tab contents via hover over tab title area

Hi,

I'm using the RibbonView version 2012.1.326. I would like to to be able to display the contents of each tab as a user hovers over the title area of each tab when the Ribbon is minimized. I would like the Ribbon to return to the minimized state when the user moves the mouse off of the tab. Are there any hover or mouseover events for the tab that I could subscribe to inorder to accomplish this?

Thanks,
Trang

NotifyChanged is allways null

Hello,

I have a user control which implments INotifyPropertyChanged, and has a radTimeBar declared in xaml. I set the datacontext in codebehind to "this". However, the Property changed never gets set, so I can't update the time bar properties. Any Idea why this might be? Here is a code sample:
Thanks,
Eric

public partial class PerfPresenter : INotifyPropertyChanged

{

public static readonly DependencyProperty VisiblePeriodStartProperty =

DependencyProperty.Register("VisiblePeriodStart", typeof(DateTime), typeof(PerfPresenter));

public static readonly DependencyProperty VisiblePeriodEndProperty =

DependencyProperty.Register("VisiblePeriodEnd", typeof(DateTime), typeof(PerfPresenter));

public DateTime VisiblePeriodStart

{

get { return (DateTime)GetValue(VisiblePeriodStartProperty); }

set

{

SetValue(VisiblePeriodStartProperty, value);

NotifyPropertyChanged(VisiblePeriodStartProperty.Name);

}

public DateTime VisiblePeriodEnd

{

get { return (DateTime)GetValue(VisiblePeriodEndProperty); }

set

{

SetValue(VisiblePeriodEndProperty, value);

NotifyPropertyChanged(VisiblePeriodEndProperty.Name);

}

public PerfPresenter()

{

this.DataContext = this;

InitializeComponent();

}

public event PropertyChangedEventHandler PropertyChanged;

private void NotifyPropertyChanged(String info)

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(info));

}

}

Binding to readonly property

Hello,

In keeping with the mvvm style, I have been trying populate the timebar intervals via binding. However, it complains at me when I try(see below) because Intervals is readonly. I noticed the interval groups and interval items properties, but I'm not sure what they do. Is there a way to populate the intervals (and acess other read-only properties such as ActualMinZoomRange) without resorting to giving the RadTimeBar and "x:Name="?

Thanks,
Eric

<telerik:RadTimeBar DataContext="{Binding}" Intervals="{Binding Intervals, Mode=OneWayToSource}"/>

What happened to the old gauge controls?

I evaluated the WPF gauge controls a few version ago, and the controls in the demo were very different (nicer, I think). They were so nice that I used a screen shot to capture them and bring it directly into my photoshop design. I've finally completed the design phase and am ready to bring the code back in, but I can't seem to find the source code example to make the gauge look like what I saw in the demo.

Am I looking in the wrong place? Have the controls changed so drastically that I can't use the old design? I've attached an image of the control I borrowed from an earlier telerik demo...

Any chance this sample code is still laying around you can share?

Programmatic Grouping by Column bound to data with converter

I am having trouble setting up grouping by a column that is bound to a data element that goes through a value converter. Below I am trying to group by the Reading Station Column.

<tk:RadGridView Name="RoutesGrid"
            AutoGenerateColumns="False" IsSynchronizedWithCurrentItem="True"
            ItemsSource="{Binding PagedSource, ElementName=DataPager}" SelectedItem="{Binding SelectedRoute}"
                        tk:StyleManager.Theme="Summer" MouseRightButtonDown="RadGridView_MouseRightButtonDown">
            <!--<tk:RadGridView.GroupDescriptors>
                <tk:ColumnGroupDescriptor Column="{Binding Columns[\Reading Station\], ElementName=RoutesGrid}" />
            </tk:RadGridView.GroupDescriptors>-->
            <tk:RadGridView.Columns>
                <tk:GridViewDataColumn
					Header="ID"
					DataMemberBinding="{Binding ID}"
					TextAlignment="Center">
                </tk:GridViewDataColumn>
                <tk:GridViewDataColumn 
					Header="Reading Station"
					DataMemberBinding="{Binding ReadingWorkstation, Converter={StaticResource WorkstationToNameConverter}}"
					TextAlignment="Center" Width="Auto">

Enable X-axis zoom with DateTime data

Hi all,

I am just starting to implement zoom/scrolling for my RadChart. However, I am running into the problem where my X axis data type is DateTime, thus when I add ZoomScrollSettingsX it gave me "Cannot convert from Double to DateTime" error. Can someone get me started on creating a custom ZoomScrollSettings?

Much appreciated,
Jin

Custom Filtering Control

A while ago I built a custom Filtering Control for a boolean column based upon this article http://www.telerik.com/help/wpf/gridview-filtering-custom-filtering-controls.html (Shown in BeforeUpdate.png). It worked fine in version 2012.1.326.40. I have recently updated our version to 2012.2.725.40 and it now shows as AfterUpdate.png. the code I have in the method that Implement IFilteringControl.Prepare does get hit when the control is shown, it just is showing what looks to be the default filtering control and not my custom one.

I have used Style Templates for almost every part of the RadGridView, is there one I just need to update or something? Just not sure how to fix the issue since all i did was update to your latest Telerik version. Was there something that was changed which disabled custom Filter controls?
