Hello, I am trying to bind the items of my RadTreeView to IsSelected and IsExpanded but when I use all my items are not visible in the tree.

I use it like this:

I tried to add to the style BasedOn="{StaticResource RadTreeViewItemStyle}" but I received warning that the style cannot be resolved, how can I use it?

Is there any way to hide a cell's tool tip when it's defined at the column level like so?

When ToolTipValue is null or empty, the tool tip still comes up, just without any content. I'd prefer if it wasn't displayed at all.

Hi, 

I'm using RadRibbonWindow in my WPF application and in Loaded event of the window I'm showing a dialog/messagebox, but the problem is that when I launch the application the main radribbonWindow doesn't show up until all interrupts/events executed from Loaded event are resolved. Why is that I want to show both simultaneously when I launch the application. 

<RibbonWindow x:Class="DynamicToolbarItems.MainWindow"

                xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
                Title="MainWindow"
                Height="350" Width="525"
                Loaded="Window_Loaded">

/*******************************code behind *************************************/

 private void Window_Loaded(object sender, RoutedEventArgs e)
 {

System.Windows.MessageBoxResult result = System.Windows.MessageBox.Show("All Changes will be lost?", "message,                    System.Windows.MessageBoxButton.YesNo, System.Windows.MessageBoxImage.Question);

        }

According to normal behavior of WPF window, Loaded event occurs when the element is laid out, rendered, and ready for interaction.It is the last event raised in an element initialization sequence. Where as in RadRibbonWindow I have observed that the Loaded event is the first one to be called, even before the Window is shown at all. And when loaded event finished its work then Window appears on screen with all its content loaded. This behavior confuses with the description of Loaded event here  https://docs.microsoft.com/en-us/dotnet/api/system.windows.frameworkelement.loaded?redirectedfrom=MSDN&view=netframework-4.7.2 ?

Hi,

I am experiencing a rather odd behavior, when i try to use the pin functionality on a gridview with datapager.

The gridview is bound to a VirtualQueryableCollectionView, which only load the relevant data based on the page shown. If I pin rows on page 1, all seems to be working fine. But when I pin a row on page 2 (Or above), Only the pinned row is shown at top, and the rest of the items are blank. When I unpin, all data are presented as expected.

I have reproduced the behavior in the attached project.

Am I missing something?

Best Regards 

Dennis

Hello,

Please let me know if I am able to create GridView for cash report like in attachment (screenshot from Excel).

I want to have custom function which sum row from column F and G, in row in column H we have value before minus this sum.

It is possible to restore selected value in the view model i'm trying 
something like this but combobox do not changed to the correct item you see last selected from the use 

<telerik:RadComboBox ItemsSource="{Binding Tests}" Width="150" Height="25"
                             SelectedValuePath="Id">
            <telerik:RadComboBox.SelectedValue>
                <Binding Path="SelectedTestId" Mode="TwoWay" BindsDirectlyToSource="True" UpdateSourceTrigger="PropertyChanged"/>
            </telerik:RadComboBox.SelectedValue>
            <telerik:RadComboBox.ItemTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}"/>
                </DataTemplate>
            </telerik:RadComboBox.ItemTemplate>
        </telerik:RadComboBox>

     public int SelectedTestId
        {
            get
            {
                return selectedTestId;
            }
            set
            {
                OldSelectionTestId = selectedTestId;

                SetProperty(ref selectedTestId, value);

                if (OldSelectionTestId > 20 && SelectedTestId == 20)
                {
                    Debug.WriteLine($"oldSelectionTestId = {OldSelectionTestId}");
                    Debug.WriteLine($"SelectedTestId = {SelectedTestId}");
                    HasError = true;
                }
            }
        }

Observe any other edit control in existence. When you hold the arrow key down to move the caret through text, it stays visible and does not blink until a brief pause after you take your finger off. Unfortunately in RadRichTextBox it keeps blinking so you lose track of where it is. This is very frustrating when you are navigating long documents because it can even prevent you from seeing the caret moving to a different line. Or hold down any character key and the caret disappears completely, giving you one less cue that something is haywire if your arm is leaning on the keyboard.

This isn't a bug per se but it isn't a minor usability issue either. What has to happen is an idle timer begins *immediately after* a key down, during which no blinking can begin. If a key down happens again, the timer resets. If the timer expires, then that starts the caret show timer.
