  • WPF version Q2 Service Pack 1 Nightly Build on 8/13/2009
  • OS - Windows 7 64-bit and Windows Vista 64-bit
  • exact version of the Telerik product - 2009.2.911.35
  • preferred programming language C#

1. I have several different styles of grids. I have a Heirarchical Grid and the arrow down selection it works only if you collapse the parent and then click somewhere near the + expander column with out expanding it. You can witness this wierd behavior on the First Look Sample.

2. Take a look at the Template and Unbound Sample. If you scroll to the bottom using the arrow keys and navigate 1 past the last row you can no longer move back up. This is a problem in several of the samples.

3. I have a grid with custom columns using Templated Columns and I cannot scroll through these at all with the arrow keys.

<telerik:RadGridView ColumnsWidthMode="Fill" AutoGenerateColumns="False" ItemsSource="{Binding Birth.MedicalInstrumentList_}" Height="200" HorizontalAlignment="Left" Margin="-492,0,0,-305" VerticalAlignment="Bottom" Width="465.117">  
                                    <telerik:RadGridView.Columns> 
                                        <telerik:GridViewColumn Width="25">  
                                            <telerik:GridViewColumn.CellTemplate> 
                                                <DataTemplate> 
                                                    <CheckBox Style="{StaticResource DeleteCheckBoxStyle}" HorizontalAlignment="Center" IsChecked="{Binding IsSelected, Mode=TwoWay}" /> 
                                                </DataTemplate> 
                                            </telerik:GridViewColumn.CellTemplate> 
                                        </telerik:GridViewColumn> 
                                        <telerik:GridViewDataColumn Header="Name" Width="2*" DataMemberBinding="{Binding Path=Equipment.Name}" /> 
                                        <telerik:GridViewDataColumn Header="Description" Width="3*" DataMemberBinding="{Binding Path=Equipment.Description}" /> 
                                        <telerik:GridViewColumn Width="175" Header="Comments">  
                                            <telerik:GridViewColumn.CellTemplate> 
                                                <DataTemplate> 
                                                    <usercontrol:TextExpander ExpanderText="{Binding Comment, Mode=TwoWay}" /> 
                                                </DataTemplate> 
                                            </telerik:GridViewColumn.CellTemplate> 
                                        </telerik:GridViewColumn> 
                                    </telerik:RadGridView.Columns> 
                                </telerik:RadGridView>

Hi Billy Jacobs,

We are currently working on improved arrow key navigation that will introduce more consistent user experience and we hope that the problems that you have reported in bullets 1 and 2 will be a thing of the past.

Unfortunately I was unable to reproduce the problem that you have reported in bullet 3. I guess the XAML code is not enough. The TextExpander control might be the key to solving this problem. Could you send us a sample application that we can use to reproduce the problem?


Kind regards,
