Hello,
I am writing a desktop application using WPF and RadGridView. I need to be able to operate 100% of the application without a mouse (keyboard navigation to every aspect of the application).
Is it possible to access column headers via keyboard navigation? If so, how do you do it?
Thanks.

The DataTrigger for the GridView works, while the DataTrigger for the Button does not: No matter, what the bound Type property's value is, the button stays visible.<telerik:RadToolBar Grid.Row="0"> <telerik:RadButton> <telerik:RadButton.Style> <Style TargetType="telerik:RadButton"> <Style.Triggers> <DataTrigger Binding="{Binding Type}" Value="{x:Static data:ReceiverGroupType.Fix}"> <Setter Property="Visibility" Value="Collapsed"/> </DataTrigger> </Style.Triggers> </Style> </telerik:RadButton.Style> <telerik:RadButton.Content>
...
</telerik:RadButton.Content> </telerik:RadButton></telerik:RadToolBar>
<telerik:RadGridView Grid.Row="1" ...> <telerik:RadGridView.Columns> ... </telerik:RadGridView.Columns> <telerik:RadGridView.Style> <Style TargetType="telerik:RadGridView"> <Style.Triggers> <DataTrigger Binding="{Binding Type}" Value="{x:Static data:ReceiverGroupType.Fix}"> <Setter Property="Visibility" Value="Collapsed"/> </DataTrigger> </Style.Triggers> </Style> </telerik:RadGridView.Style> </telerik:RadGridView>
Hey,
I'm trying to change the RadSplitButton to have a background image similar to a ImageButton. Is this possible? If so, how?
Thanks

Hello, Is there a way to bind the sort index to a property?
For example, we have the following class
public class Foo
{
public string Name { get; set; }
public int SortIndex { get; set; }
}
If the user clicks a column header and turns it to ascending order then the the SortIndex of the items should be updated with respect to how it was sorted in the UI.
Thanks!

UI for WPF 2019.1.220.45, Windows 10 Pro 64, Visual Studio Community 2019 v16.0.3
I'm trying to attach a context menu to a draggable listbox item, and after a great deal of effort, I've finally gotten it to the point where I can right click anywhere on the item (except for when the cursor is over a control with its own context menu, which is desired behavior). So, this is functioning exactly as I want it to from a UI standpoint. The problem is that the moment I add a Click property to the menu item in the xaml, the app throws an exception during the construction of the listbox.
Here's the xaml
<UserControl x:Class="MIDIMan.ZWMIDIInPortList" xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" xmlns:local="clr-namespace:MIDIMan" xmlns:viewmodel="clr-namespace:MIDIManViewModel;assembly=MIDIManViewModel" xmlns:telerikDragDrop="clr-namespace:Telerik.Windows.Controls.DragDrop;assembly=Telerik.Windows.Controls" mc:Ignorable="d" d:DesignHeight="450" d:DesignWidth="800" BorderBrush="Black" BorderThickness="1"> <UserControl.Resources> <viewmodel:InPortsViewModel x:Key="InPortsViewModel"/> <DataTemplate x:Key="InPortListTemplate"> <Grid HorizontalAlignment="Left"> <Grid.RowDefinitions> <RowDefinition/> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <CheckBox IsChecked="{Binding IsActive}" /> <TextBox Grid.Column="1" Text="{Binding PortName}" Width="Auto" BorderBrush="White" /> </Grid> </DataTemplate> <Style x:Key="DraggableListBoxItem" TargetType="telerik:RadListBoxItem"> <Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" /> <Setter Property="ContextMenu"> <Setter.Value> <ContextMenu> <MenuItem Header="Restore port name" Click="MenuItem_Click"/> </ContextMenu> </Setter.Value> </Setter> </Style> </UserControl.Resources> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="30"/> <ColumnDefinition Width="65"/> <ColumnDefinition Width="Auto"/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition/> <RowDefinition/> <RowDefinition/> <RowDefinition/> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="3" Text="Input Ports" HorizontalAlignment="Center"/> <TextBlock Grid.Row="1" Grid.Column="0" Text="Active" HorizontalAlignment="Center"/> <TextBlock Grid.Row="1" Grid.Column="1" Grid.ColumnSpan="2" Text="Name" HorizontalAlignment="Center"/> <telerik:RadListBox Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="3" ItemsSource="{Binding MIDIInPorts, Source={StaticResource InPortsViewModel}}" ItemTemplate="{StaticResource InPortListTemplate}" ItemContainerStyle="{StaticResource DraggableListBoxItem}" HorizontalAlignment="Stretch" Height="Auto"> <telerik:RadListBox.DragDropBehavior> <telerik:ListBoxDragDropBehavior AllowReorder="True" /> </telerik:RadListBox.DragDropBehavior> <telerik:RadListBox.DragVisualProvider> <!--<telerik:ScreenshotDragVisualProvider />--> <telerik:ListBoxDragVisualProvider/> </telerik:RadListBox.DragVisualProvider> </telerik:RadListBox> <StackPanel Orientation="Horizontal" Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="3" HorizontalAlignment="Center"> <TextBlock Text="{Binding MIDIInPortCount, Source={StaticResource InPortsViewModel}}" Margin="0,0,5,0"/> <TextBlock Text="Ports" /> </StackPanel> </Grid></UserControl>
I had been trying to put the ContextMenu in the ListBoxItem template, but was having no luck, when I ran across a forum post somewere that suggested putting it in its style instead, and that's what we have here. You'll find it right about in the middle of the code - just a single MenuItem, "Restore port name". If I remove the MenuItem altogether, the app runs fine and when I right click on the ListBoxItem, an empty context menu pops up. If I add the MenuItem with no Click property, the context menu pops up and shows the menu item. Add the Click property definition and, boom! Exception thrown.
I'm attaching some pictures that include what the list box looks like and the exception warning and details.
I wanted to use the RadContextMenu, but the app wouldn't build because it only allows ContexMenu at that point. (Different exception)
Any suggestions as to what I might do to get it working?
Thanks,
Ken
I did some searching around but couldn't find anything about this, and I surprised it hasn't come up. I have several hotkeys using input bindings, which include "Alt" modifiers. They input bindings do work and run the command they are supposed to, but the access keys also come up. Is there a way I can prevent the ribbon from showing the access text when I also have an input binding which handles it?
In Excel, for example, you can press Alt+ to do auto sum, and it doesn't show the access text, so it's not like this is how the ribbons are supposed to work.

Hi, I use your viewing schedule, but I'm confronted with this problem when more than 500-1000 appointments are assigned to the "month" of the navigation header, the slots on certain days are empty, although there are tasks these days.
Could there be a certain limit on the number of appointments?
Thank you for your support!
