Hi,

We are unable to use Keyboard's Up and Down keys for a simple up and down (row by row) scolling.
The code is as follows:
<telerik:RadGridView ItemsSource="{Binding AllActivities}" Name="ui_grd_AllActivityDetails" ShowGroupPanel="False" RowIndicatorVisibility="Collapsed" AutoGenerateColumns="False" IsEnabled="True">

What could be the issue. This is happening thorught our Silverlight 4.0 application. I will really appreciate your help.
Thanks in advance!

Hello Sanjay ,

I have tested the issue you specified on our demos, but unfortunately I was not able to reproduce it. Can you get the same behavior in this example ? Is there anything more specific that you do - do you handle any of the key-events or override the default keyboard command provider ? 

Best wishes,

Hello Maya,

Please see my comments below:

Is there anything more specific that you do?
Our Silverlight plugin/app is hosted in a WPF Browser control. It's "In browser" app hosted in WPF control to support external communications. I attaching the code for your review. Could this be a RadTileView issue?
<ScrollViewer>
        <telerik:RadTileView x:Name="tv_DoamainHeader" Margin="0 0 7 0" MaximizeMode="One" HorizontalAlignment="Left" Width="Auto" Height="Auto" MinWidth="500">
            <telerik:RadTileViewItem x:Name="ui_tviDomainItem" TileState="Maximized" Style="{StaticResource iconlessTemplate}">
                <telerik:RadTileViewItem.Header>
                    <StackPanel Orientation="Horizontal">
                        <Grid Width="Auto" >
                            <Grid.RowDefinitions>
                                <RowDefinition Height="Auto"></RowDefinition>
                            </Grid.RowDefinitions>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition Width="Auto" />
                                <ColumnDefinition Width="Auto" />
                            </Grid.ColumnDefinitions>
 
                            <Grid x:Name="ui_grdTextBlock" Grid.Row="0" Grid.Column="0">
                                <TextBlock Text="Maintain Domain Activities" Margin="8,3,0,0" FontWeight="Black"/>
                            </Grid>
 
                            <uc:CRUDControl x:Name="ui_ucCRUDControl" Grid.Row="0" Grid.Column="1" ></uc:CRUDControl>
                        </Grid>
                    </StackPanel>
                </telerik:RadTileViewItem.Header>
 
 
                <StackPanel>
                    <telerik:RadBusyIndicator Grid.Row="1" BusyContent="Loading..." IsBusy="{Binding ShowLoader}">
                        <telerik:RadGridView  x:Name="grd_DomainActivitiesDetails" Grid.Row="2" Grid.Column="0" IsReadOnly="False" 
                                  AutoGenerateColumns="False" ItemsSource="{Binding MaintainDomainActivitiesList}"
                                  ShowGroupPanel="False"
                                              DataLoaded="grd_DomainActivitiesDetails_DataLoaded"
                                              SelectionChanged="grd_DomainActivitiesDetails_SelectionChanged" RowIndicatorVisibility="Collapsed" SelectionMode="Single" ValidatesOnDataErrors="Default"
                                          ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Visible" IsFilteringAllowed="False"
                                              >
                            <telerik:RadGridView.Columns>


Do you handle any of the key-events or override the default keyboard command provider ?
No, we have not created and used ny of our KeyboardCommandProvider yet.

Please let me know if you have any questions. I will really appreciate your help.

Hello Maya,

TAB, PageUp and PageDown keys work just fine but not Key Up and Key Down keys. Thanks

Hello Sanjay ,

You can see the version of the GridView assembly either through its properties in Visual Studio or clicking directly in the properties of the dll from the containing folder. I am attaching an image illustrating it.
Considering the navigation, may you clarify whether you are working with RadGridView for Silverlight or RadGridView for WPF ?

Hello Maya,

The version is :
Runtime Version is V2.0.50727
Version is 2011.2.712.1040

Also it's a Silverlight 4.0 application. Please let me know if this is a versioning issue. Your version seems to be the latest. Thanks

Hello Vlad,

Your demo of Gridview supports keyboard. Is it built using latest version? Thanks

Hello,

Actually, you are supposed to be able to navigate with the keyboard in previous version than our current one without any problems. And for the time being we are not aware of any issues with it in the version you are using. I am attaching a sample project with the binaries you are currently using. Could you take a look at it and let me know whether you can get the same behavior on it ? Could you try to update it so that it meets your exact scenario and let me know whether you can reproduce the issue ? 
Nevertheless, my recommendation would be always to work with our latest official version thus being able to benefit from all the improvements and bug fixes we have introduced.
 

All the best,
