Right mouse click unselects one of many selected rows

I'm using version 2012.2.607.40.

I have a GridView with SelectionMode=Extended. If a user selects multiple rows by left clicking on row #2 followed by holding the shift key down and left clicking on row #5, they end up with 4 rows (row numbers #2 through #5) selected/highlighted. This is all fine.

Next, if the user right clicks on row #5, to open a context menu and perform some function on the selected rows, row #2 looses its highlighted background color and appears to no longer be selected, even though it is. This causes confusion for the user. How can I avoid one of the rows from loosing that highlighted color after right clicking one of the selected rows?

It should be noted that this behavior does NOT occur if the user holds the Ctrl key down while left clicking individual rows to select multiple rows. It is only when the Shift key is used to select a range of rows.

Thank you,

James

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.

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,

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
