Can't remove light rendered series

Pseudo code to reproduce the problem.

1. void OnFirstButtonClick(){

Chart.Series.Clear();

var series = new LineSeries() {RenderMode = SeriesRenderMode.Light};

Chart.Series.Add(series);

}

// I can see added series, it's OK

2. void OnSecondButtonClick(){

Chart.Series.Clear();

var series = new LineSeries();

Chart.Series.Add(series);

}

// I see new series and series from the first step. Why?

// If the first series are rendered with Full RenderMode, I see only the second.

[Solved] trying to run existing application with RadRibbonWindow in Win8... Aero2 error

I am trying to run an existing application in the debugger on a Windows 8 machine to prepare for the future, and I am getting the following errror on the constructor of the RadRibbonWindow:

Could not load file or assembly 'Telerik.Windows.Controls.RibbonView.Aero2, Version=2012.2.607.40, Culture=neutral, PublicKeyToken=5803cfa389c90ce7' or one of its dependencies. The system cannot find the file specified.

I cant find any reference to Aero2 in either the RadRibbonWindow or RadRibbonView assemblies. Can anyone tell me what is causing this and how to fix it?

PieSeries OffsetFromCenter not being reapplied after Selection

I've observed that when a Slice is selected and deselected again in the PieSeries, then the Offset which is set in the <PieDataPoint/> tag is not being applied anymore and the slice/piedatapoint loses the offset that was set initially. Is this a bug or am I doing it wrong?

[code]
<telerik:RadPieChart>
<telerik:PieSeries ShowLabels="False" SelectedPointOffset="0.03">
<telerik:PieSeries.DataPoints>
<telerik:PieDataPoint Value="27" OffsetFromCenter="0.02"/>
<telerik:PieDataPoint Value="33" OffsetFromCenter="0.02"/>
<telerik:PieDataPoint Value="40" OffsetFromCenter="0.02"/>

</telerik:PieSeries.DataPoints>
<telerik:PieSeries.AngleRange>
<telerik:AngleRange StartAngle="270" SweepAngle="360" />
</telerik:PieSeries.AngleRange>
</telerik:PieSeries>
<telerik:RadPieChart.Behaviors>
<telerik:ChartSelectionBehavior DataPointSelectionMode="Single">
</telerik:ChartSelectionBehavior>
</telerik:RadPieChart.Behaviors>
</telerik:RadPieChart>
[/code]

Also, how does the SelectedPointOffset property work? I don't see the effect of 0.03 offset for the selected slice when I select a slice - the offset is much more than that for the slice which is selected

Issue with marked zone annotation referring to secondary axes

Good morning, in my project I have to refer marked zone annotations to a secondary Y axes, but it does not seem to work.
Project involves complex logic with the MVVM pattern, in order to try to understand what is going on I made up a simple example (below), but still does not work. Marked zone annotation must be referred to secondary Y Axes, called "Height", but still refers to the primary one.
Please tell me what am I missing,

[Solved] ColumnGroups do not display when set by code

Hi,

I am trying to implement the new ColumnGroups introduced in the latest version (2011 Q3) but I am having issues when trying to create the ColumnGroups by code.

The problem occurs when trying to construct ColumnGroups with the below code. (taken from a simple sample to isolate the issue)

            this.grid.Columns.Clear();

            this.grid.ColumnGroups.Clear();

            var gridColumn = new GridViewDataColumn();

            var gridColumn2 = new GridViewDataColumn();

            if (this.IncludeGroup.IsChecked != null && (bool)this.IncludeGroup.IsChecked)

            {

                this.grid.ColumnGroups.Add(new GridViewColumnGroup

                    {

                        Name = "A",

                        Header = "A"

                    });

                this.grid.ColumnGroups.Add(new GridViewColumnGroup

                {

                    Name = "B",

                    Header = "B"

                });



                gridColumn.ColumnGroupName = "A";

                gridColumn2.ColumnGroupName = "B";

            }



            gridColumn.UniqueName = "a";

            gridColumn.Header = "Name";

            var textBinding = new Binding("Name");

            textBinding.Mode = BindingMode.OneWay;

            gridColumn.DataMemberBinding = textBinding;

            this.grid.Columns.Add(gridColumn);

            

            gridColumn2.UniqueName = "b";

            gridColumn2.Header = "Name";

            var textBinding2 = new Binding("Year");

            textBinding2.Mode = BindingMode.OneWay;

            gridColumn2.DataMemberBinding = textBinding2;

            this.grid.Columns.Add(gridColumn2);

It will refresh the whole GridView correctly except for the ColumnGroups.

Any help would be much appreciated,
Rich

Windows8TouchTheme

Hi,

I am using the following to define a GridView Column

<telerik:GridViewDataColumn
DataMemberBinding="{Binding IsSelected}"
IsFilterable="False"
Header="">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding IsSelected, Mode=TwoWay}"
Checked="IsSelected_Checked"
Unchecked="IsSelected_Unchecked"/>
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

The default theme and the Windows7 theme works as expected but the Windows8Theme has the following behavior. I have to hit the screen to the right of the checkbox to check the item and when I put the mouse directly on the checkbox I get the sizing icon. I assume it has something to due with the fact that the CheckBox is a Windows control?

I originally defined the column as telerik:GridViewCheckBoxColumn but that did not provide me with Checked and Unchecked events. I then went to the above code which I got from the forum. It seems to me that the telerik:GridViewCheckBoxColumn should provide the checked events otherwise why have it? When and if its decided to make a change to telerik:GridViewCheckBoxColumn for the checked events I would also suggest that you provide a property to not dim the checkbox whether the row is selected or not.

Thanks
Rich

Custom Interval Formatters

Hi,

Summary:
How can I customize the interval formatter for hours to display 24-hour time?

Background:
I've found the default interval formatters detailed here:
http://www.telerik.com/help/wpf/radtimebar-intervals-formatters.html

I have my Windows regional settings set to 24-hour time (without any suffix) and what I'm finding is that the hour interval for the RadTimeBar is displaying in 12-hour time, however without any suffix, presumably because Windows regional settings do not specify a suffix when set to displaying 24-hour time. This makes it a little more ambiguous for the user who is expecting 24-hour time, however gets 12-hour time instead.

How can I customize the interval formatter for hours to display 24-hour time?

Kind regards,
Dave.

Breaking Change in Q1 2013 release with Caliburn Micro

Upgrading to the latest Telerik release results in a NullReferenceException in Caliburn Micro ActionMessage.SetMethodBinding on application load. The issue is specific to the ExecuteOnLoad event handler Sequence which tries to resolve bindings for the control that is loading.

In our case, the control is a RadButton. The Exception is thrown when the Source property of the ActionExecutionContext in Caliburn Micro is dereferenced. The Source property is set to the value of the ActionMessage’s AssociatedObject property when the object is constructed a few frames higher on the call stack.

For some reason, the AssociatedObject property is set correctly with the Button controls in the prior telerik release, but not with this latest one.

Additionally, this problem is specific to Caliburn Micro Actions set up in Styles vs. on the control itself. IOW this code causes the exception:

        <Style x:Key="FooStyle" TargetType="telerik:RadButton">

          <Setter Property="ToolTip" Value="Foo Tip"/>

          <Setter Property="cal:Message.Attach" Value="[Click]=[Foo]"/>

        </Style>

        <telerik:RadButton x:Name="_fooButton" Style="{StaticResource FooStyle}"/>


While this code does not
         <Style x:Key="FooStyle" TargetType="telerik:RadButton">

          <Setter Property="ToolTip" Value="Foo Tip"/>

        </Style>

        <telerik:RadButton x:Name="_fooButton"

                           Style="{StaticResource FooStyle}"

                          cal:Message.Attach = "[Click]=[Foo]"/>

Again, setting the Message.Attach property in a style worked fine in the last Telerik release. It causes an exception in this latest release.

We have many buttons in our application that are styled like this and it will be a large effort to convert them as a workaround in order to use the latest Telerik controls. Before we do so, we’d like to know what changed and whether there is a less invasive workaround.
