I have a fairly complex WPF app running on a surface tablet.

Occasionally touch just stops working.

Mouse and keyboard work fine if they are attached or if I connect with a remote program.

I have posted this in the buttons area but really it could be anywhere.

It does matter where in the software it is . it can occur anywhere

Has any one seen this ?

Any help from telerik or community would be appreciated.

Hi,

I have a GridViewDataColumn binded to an object field. All records are of the same type (homogeneous).

In this case data are shown in the GridViewDataColumn but the column cannot be filtered nor sorted.

For example if you have a string data and you set DataType Property and FilterMemberType Property with value typeof(string), you can filter and sort the column. Moreover, if you use the function Search As You Type (CTRL+F) it does not work for this column.

Any suggestions?

Thank you

Hi,

I want to disable the TabStop mecanism in the RadPanelBar so that the user can't focus on the RadPanelBar or RadPanelBarItems using the "tab" key. I've managed to disable most TabStop mecanism in the RadPanelBar except for one that I really don't understand.

The following project demonstrates my problem. I would like for the tab key to navigate between the 3 textbox without the focus going to the RadPanelBarItem.

I currently implemented Excel Export behind code, I'm trying to have it be implemented in the ViewModel Instead. How abouts would I do that?

        private void MenuItem_OnClick(object sender, RoutedEventArgs e)
        {
            try
            {
                string content;

                var extension = "xml";
                content = DrillThroughGridView.ToExcelML(true);

                string path = String.Format("Export.{0}", extension);

                if (File.Exists(path))
                {
                    File.Delete(path);
                }

                using (FileStream fs = File.Create(path))
                {
                    Byte[] info = Encoding.Default.GetBytes(content);
                    fs.Write(info, 0, info.Length);
                }

                Process.Start(path);
            }
            catch (Exception)
            {
                Notification.Error("Process Busy", "Please exit excel instance.");
            }
        }​

                            </telerik:RadTileViewItem>

Then in my mainWindowViewModel I have

private TileViewItemState _TileStaterdTileViewMain;

        public TileViewItemState TileStaterdTileViewMain
        {
            get {
                return _TileStaterdTileViewMain;
            }
            set {
                _TileStaterdTileViewMain = value;
                PropertyChanged(this, new PropertyChangedEventArgs("TileStaterdTileViewMain"));
            }

 private void RaiseUpUcShopOrdersButtonControl(object parameter)
        {
            TileStaterdTileViewMain = Telerik.Windows.Controls.TileViewItemState.Maximized;
   
        }

Can someone help me to know If I missing something?

Thanks 
        

Hello I will appreciate your help with the Next I need to Maximized RadTileViewItem Programatically, But it is not running 

My XAML

<telerik:RadTileViewItem x:Name="rdTileViewMain" Header="Main" RestoredHeight="100" MinimizedHeight="200" RestoredWidth="80" Style="{StaticResource RadTileViewItemStyle}" BorderBrush="{x:Null}" SnapsToDevicePixels="True" Foreground="#FFFDFBFB" TileState="{Binding TileStaterdTileViewMain}">

Then in my MainWindowViewModel:

     private TileViewItemState _TileStaterdTileViewMain;

     public TileViewItemState TileStaterdTileViewMain
        {
            get {
                return _TileStaterdTileViewMain;
            }
            set {
                _TileStaterdTileViewMain = value;
                PropertyChanged(this, new PropertyChangedEventArgs("TileStaterdTileViewMain"));
            }

        }

   private void RaiseUpUcShopOrdersButtonControl(object parameter)
        {
            TileStaterdTileViewMain = Telerik.Windows.Controls.TileViewItemState.Maximized;

}

Just now installed Telerik for WPF

Opening Visual Studio, creating project Telerik C# WPF Application, selecting "Blank" and "Finish".

Opening MainWindow.xaml, dragging RadRichTextBox from toolbox and dropping into Grid.

But here is Object reference not set in output log. When running - it crashes. Point.

RadButton works correctly.

Result code is here: https://pastebin.com/yVSNDbMH

Visual Studio is 2017

OS is Windows Server 2012

Locale is ru-RU

Telerik Installer is TelerikUIForWpfSetup_2017_3_0814_1.exe

C:\Program Files (x86)\Telerik\UI for WPF R2 2017\Binaries\WPF40\Telerik.Windows.Controls.RichTextBoxUI.dll file version is 2017.2.614.40

If you have different version and haven't problem, please give me installer or just this DLL, I'll try fix or search a bug with .NET Reflector

I have a RadAutoCompleteBox in RadGridView CellEditTemplate

SearchText is in dropdown ItemsSource, when I click the cell and enter edit mode, Loaded event fired and both SearchText and SelectedItem has value, but when I just press Esc to exit edit mode and in Unloaded event, SearchText still has value but SelectedItem is null.

Why this happened and how to fix it? Thanks.

"Header" is returned from "Value".
