Hi,

I am using <telerik:RadTreeListView> and the scroll functionality does not work. this is how my code looks like:

<UserControl x:Class="WISN.Windows.Survey.FacilityStaffControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:vm="clr-namespace:WISN.Windows.Survey.ViewModels"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             mc:Ignorable="d" 
             d:DesignHeight="450" d:DesignWidth="800">

    <telerik:RadTreeListView x:Name="stufftreeListView" AutoGenerateColumns="False"
                                 AutoExpandItems="True" GroupRenderMode="Flat" CanUserDeleteRows="False"
                                 ItemsSource="{Binding AllStaffByType,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged }">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding StaffCategories,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}"></telerik:TreeListViewTableDefinition>
            </telerik:RadTreeListView.ChildTableDefinitions>

            <telerik:RadTreeListView.Columns>
                <telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding IsSelected}" AutoSelectOnEdit="True" EditTriggers="CellClick">
                    <telerik:EventToCommandBehavior.EventBindings>
                        <telerik:EventBinding Command="{Binding CustomCommandCommand}" EventName="MouseLeftButtonDown" />
                    </telerik:EventToCommandBehavior.EventBindings>
                </telerik:GridViewCheckBoxColumn>
                <telerik:GridViewDataColumn IsReadOnly="True" DataMemberBinding="{Binding Name}" Header="Stuff"></telerik:GridViewDataColumn>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding AnnualSalary}" Header="Annual Salary"></telerik:GridViewDataColumn>
            </telerik:RadTreeListView.Columns>
        </telerik:RadTreeListView>
</UserControl>

 

I really do not know how to fix it.

Thanks

I've used RadGrid and inside that I have one listview with expander control. It is working fine and Expander also expanding and collapsing fine.

But only one issue I have is, when I expanded the Expander and try to scroll down the RadGrid, Expander collapsing every time, it is not retaining it's previous expand state.

I could overcome this by disabling the Virtualization on RadGrid but in that case RadGrid taking long time to load/render.

 

Any help would be appreciated.

Thanks,

Hi,

I have a list of RadExpander, inside every Radexpander there is a Radgridview. When  I expand, expander height grow over the size of window and a scroll bar appears in expander control itself.
I would like that expander doesn't grow over the window and the scroll bar appears in the gridview. I could achieve this behaviour setting maxheight in gridview, but I don't want to limit the height of grid.In first attachment the situation when maxheight is not set, in the second with maxheight set, I would achieve the second situation but without setting maxheight.

Thank you

Luigi

 

Below it is the xaml as appears in LiveVisualTree: I think that the real one it is too much complex to understand the situation quickly.
