[Solved] 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,

The problem you reported has already been fixed. So, could you please give it a try with the latest internal build available and let us know if that worked for you.


Kind regards,

Hello,
I have downloaded the latest internal build an bring it in our application. It works but not as expected. For instance in one grid pressing <PageDown> key scrolls the rows down(as expected), but when I came back to the first item and again press <PageDown> there is no effect.
Regarding the last internal build, I have noticed that Telerik.Windows.Controls.DependencyObjectExtention.FindChildByType<T>() method is missing. It will be greate to have it back again.

Thank you.

Kind regards,
Alexander

Please take in account that the height of rows in grid(where the problem appears) is not the same for all rows. Height for some rows is bigger, for others are smaller depending on the text inserted in the cells of row.

Hi Alexander,

I am not able to reproduce the problem you described. May you take a look at the project I have attached to verify whether I am missing something. Let me know If you can reproduce the same behavior on it.
Regarding the missing method, it will be included in the next internal build.


All the best,
Vera
