When the user drags an item to the top or bottom of the TreeListView, I'd like to scroll automatically, to handle the case where the user wants to drag to an item that isn't currently in view. I have a small sample program I can provide you, and OnDragOver is shown below. Can you tell me how to detect that the drag has reached the top or bottom of the view and then scroll as needed?

Thanks,

Georg Hentsch

        private void OnDragOver(object sender, Telerik.Windows.DragDrop.DragEventArgs e) {
            var dropTarget = e.OriginalSource as TreeListViewRow ?? (e.OriginalSource as FrameworkElement).ParentOfType<TreeListViewRow>();
            var details = DragDropPayloadManager.GetDataFromObject(e.Data, "DropDetails") as DropIndicationDetails;

            if (dropTarget == null || details == null) {
                return;
            }

            details.CurrentDraggedOverItem = dropTarget.DataContext;

            if (details.CurrentDraggedItem == details.CurrentDraggedOverItem) {
                e.Effects = DragDropEffects.None;
                e.Handled = true;
                return;
            }

            details.CurrentDropPosition = GetDropPositionFromPoint(e.GetPosition(dropTarget), dropTarget);

            if (IsChildOf(dropTarget, sourceItem)) {
                e.Effects = DragDropEffects.None; // don't allow item to be dropped to one of its own children
            }

            e.Handled = true;
        }

Dear Telerik Team,

I am using telerik Rad Grid View control and having issue with below code.

I am trying to set the background color of a row on mouse over.

Issue is On mouse over below Setter property 'Background' does not set the background color of the row instead it sets the border color. Pl advise on the correct Implementation.

<telerik:RadGridView x:Name="radGridView" Margin="8,100,0,0"
                            ItemsSource="{Binding Source={StaticResource AuthorsData}}"
                           IsFilteringAllowed="True"
                           AutoGenerateColumns="True" Grid.Column="1" >
            <telerik:RadGridView.RowStyle>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="MinHeight" Value="20"/>
                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="Green"/>
                            <Setter Property="Foreground" Value="Black"/>
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </telerik:RadGridView.RowStyle>
        </telerik:RadGridView>

Thanks,

Hi 

We have a radoutlookbar with some items in it When te user click on the minimize/restore-button ((1) in attached image)  it works perfect, the bar and all it content moves out and in. (see attached image). 

When user clicks on the "header" of the outlookbar ((2) in attached image) strange things happen. First click is most often than only the first  user control in the first item slides out, after that, sometimes the entire outlookbar is stuck half minimized and we have to restart the application. 

First of all, Im I doing something wrong in my xaml (below)? 

If not, is there any setting where I can make the rest of the outlookbar to minimiza/restore or could I catch the event and programmatically restore it? (We are using te MVVM approach) 

--xaml---------------------------------------

<telerik:RadOutlookBar DockPanel.Dock="Right" Width="600" IsVerticalResizerVisible="True" MinimizedButtonContent="Details" IsMinimized="True"  >
     <telerik:EventToCommandBehavior.EventBindings>
           <telerik:EventBinding EventName="SelectionChanged" Command="{Binding DrawerItemChangedCommand}" PassEventArgsToCommand="True"/>
           <telerik:EventBinding EventName="Restored" Command="{Binding ExpandCollapseDrawerCommand}" PassEventArgsToCommand="True"/>
           <telerik:EventBinding EventName="Minimized" Command="{Binding ExpandCollapseDrawerCommand}" PassEventArgsToCommand="True"/>
      </telerik:EventToCommandBehavior.EventBindings>
      <modelview:OneView DataContext="{Binding OneViewModel}"/>
      <telerik:RadOutlookBarItem Header="Another">
             <modelview:AnotherView DataContext="{Binding AnotherViewModel}" />
       </telerik:RadOutlookBarItem>
       <telerik:RadOutlookBarItem Header="LastViewIPromise">
                <moCompliance:LastView DataContext="{Binding LastViewModel}" />
        </telerik:RadOutlookBarItem>
</telerik:RadOutlookBar>

Bonjour
Lorsque j'ouvre un PDF à l'aide du bouton "Ouvrir" de la radtoolbar DE PdfViewer, j'aimerais obtenir le chemin du PDF sélectionné. Quelle est la meilleure façon à procéder? 

Merci

We are currently setting up some tests with Microsofts UI Automation.

For my next steps I'm searching for a way to implement selection for GridView rows.
So far I couldn't really find any documentations how to deal with this with Telerik controls in detail.

Currently I access the grid, grid row and grid row cells as follows:

How can I select

• a single row
• multiple rows
• search within the grid (because it looks like rows are not available before they are processed by virtualization of the grid)

How is the RadGridView intended to be used in a automated way?

Currently I'm using .Net Framework 4 with Telerik Version 2018.3

Any help is appreciated, thanks.

Hello! 

I'm trying to figure out how to get the contents of my grid to sort by a property member that is not exposed to the UI via a column. The item source for my grid comes from a collection view defined on my ViewModel. This collection view has sort descriptors defined in C#, one of which is to sort by a boolean property that is not bound to a column on the grid, but that sort descriptor is not honored at run-time. 

Any assistance is appreciated.

We have this sort of filter

        private CompositeFilterDescriptor _deletedNewFilterDescriptor = new CompositeFilterDescriptor()
        {
            LogicalOperator = FilterCompositionLogicalOperator.Or,
            FilterDescriptors =
                    {
                        new FilterDescriptor("Column1", FilterOperator.IsNotEqualTo, "MyState"),
                        new FilterDescriptor("Column2", FilterOperator.IsNotEqualTo, "YourState")
                    }
        };

and at some point when we refresh the grid, the rows that should be filtered get displayed. So we have to do something like this which also fails on occasions

        void grd_loaded(object sender, RoutedEventArgs e)
        {
            // For some reason, adding filters in constructors gets cleared somewhere, so add in Loaded methods.
            if (!grd.FilterDescriptors.Contains(_deletedNewFilterDescriptor))
                grd.FilterDescriptors.Add(_deletedNewFilterDescriptor);
        }

Any help would be appreciated. Because we will have to filter those rows at the SQL fetching time and not afterwards. This means changing the existing code.
