RadGridView inside a TabItem (PageDown key problem)

[Alexander]

Hi everyone,
In our application we use a RadTabControl. In one RadTabItem as a content is set a RadGridView, as in code below:

<UserControl x:Class="Test.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    xmlns:local="clr-namespace:Test"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    d:DesignHeight="300" d:DesignWidth="400">

    <UserControl.DataContext>
        <local:MainPageViewModel />
    </UserControl.DataContext>

    <Grid x:Name="LayoutRoot" Background="White">
        <telerik:RadTabControl>
            <telerik:RadTabItem Header="Phones">
                 <telerik:RadGridView ItemsSource="{Binding Phones}"></telerik:RadGridView>
            </telerik:RadTabItem>
        </telerik:RadTabControl>
    </Grid>
</UserControl>

The problem appears when user selects the first row and presses <PageDown> key on keyboard, there is now scroll. Instead it changes the selected item from the first to the last item in visible area and back. If user selects other row than first and presses <PageDown>, the first row is selected and then behavior is the same as in first case
Note: This problem appears only for RadGridViews placed in TabItems

Hello Alexander,

I'm not sure if I got you right. Are you saying that the GridView does not perform scroll when PageDown is clicked? Instead the selected row jumps between the first and last rows inside the visible area. If this is the case then I'm on the right road.

However, I've created a sample project in order to simulate the issue but with no success. Can you please elaborate a bit more on the issue or take a look at the attached project and modify it in a way to repro the issue?

Greetings,
