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

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.

I'm struggling with this issue for a few days. I guess it's something with solution because the same assemblies works fine for other projects.
Also in design time designer works okay and draw controls, but in runtime I'm getting System.Windows.Markup.XamlParseException.

Telerik's References:
Telerik.Windows.Controls
Telerik.Windows.Controls.GridView
Telerik.Windows.Controls.Input
Telerik.Windows.Data

Installed Packages:
Microsoft.Bcl (1.0.19)
Microsoft.Bcl.Async(1.0.165)
Microsoft.Bcl.Build(1.0.4)

Controls version is 2013.2.724.40 for .net 4.0,
Visual Studio 2013 with latest updates,
Windows 8.1

I have tried:
1) add references for assemblies in new solution and it works okay;
2) create new project(Wpf User Control Library and Class Library) in solution;
3) uninstall Microsoft.Bcl packages;
4) download latest trial version and even designer throw exception and intellisense didn't work for http://schemas.telerik.com/2008/xaml/presentation in xaml ( <telerik: and empty list ).

So I have no idea what is going wrong... Could you help?

I am dynamically generating tabs based on databinding.  After I change the datacontext I get the tabs I expect but none of the tabs are selected. I am expecting a tab (likely the first one) to be selected when this happens.   I should mention I am using an older version R2 2017

 

<CheckBox x:Name="cbox" Click="CheckBox_Checked">Click Me</CheckBox>
<telerik:RadTabControl x:Name="tabCtrl" DisplayMemberPath="Name" ItemsSource="{Binding TabItems}" Height="250"/>
private void TabCtrl_DataContextChanged (object sender, DependencyPropertyChangedEventArgs e)
    {
    // Attempting to fixt the problem here. Tabs are still unselected when changing data context
    this.tabCtrl.SelectedIndex = 0;
    }
 
/// <summary>
/// Simulating a data context change in a complicated MVVM scenario here
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void CheckBox_Checked (object sender, RoutedEventArgs e)
    {
 
    if ( cbox.IsChecked == true )
        {
        this.tabCtrl.DataContext = m_mainVm.TabViewModelA;
        }
    else
        {
        this.tabCtrl.DataContext = m_mainVm.TabViewModelB;
        }           
    }

In the following example of MVVM application i tried to bind AccessKey to ribbon items to ribbon items. Unfortunatly the user have to navigate through ribbon and cannot use hotkey direcctly. The  user have to press hotkey for tab to can use Hotkey for button. Which is just a little bit unpractical if the user wants to use to acces functionality direct, or to inform which hotkey is for which button.

In your example for RibbonView(wpf) called "Office" ,if I press Alt  and cann see all ToolTips for. Do I miss some think in my exampple?
