I have setup in my code a RoutedCommand for escape key:

  public static RoutedCommand CloseFormCommand = new RoutedCommand();
  CloseFormCommand.InputGestures.Add(new KeyGesture(Key.Escape));

This works fine when the keyboard focus is on a control like a textbox in the form. But as soon as I click on the Grid and it is set to Edit mode pressing the Escape key will just finish the edit mode and it won't call the command unless I set the cursor back to the textbox by mouse and press the Escape key. How can I fix this problem?

I am using the grid as a read only display of data.

I would like to hide the selection row (highlighted row) in the grid.

I tried CanSelect = false but the grid still displays a highlighted row...

Thanks,

Michel

Hello!
I have a very poor performance when EnableRowVirtualization="True" and no rowHeight is set.
If I set e.g. Row.Height = 90 then everything is okay.

Any Ideas?

Thank you for the new RadRichTextBox.
I installed the new Q1 for 2011 and tried the Telerik Editor example.
Works fine, but... when I try to open or save documents as .docx (or as richtextformat) I get a messagebox: "Unsupported File format".

Office 2010 (Norwegian) is installed.

Hi,

in my RadOutLookBar, I have mutltiple group section, for each section, I have multiple buttons. When the user click on an header group item, I show a graphical representation of his stats, if the user click on a button attach to the group, I display a grid. If the user want his graphic back, he cannot just click on the group header item again because the selection_changed event wasn't fired.

What is the best approach the handle this?

Thank's

I just have put a RadBusyIndicator in my Window like this:

 <telerik:RadBusyIndicator IsBusy="{Binding IsWorking}" BusyContent="Loading..." />

And in my App object I do (OnStartup event):
    StyleManager.ApplicationTheme = new MetroTheme();
            var findResource = FindResource("BaseColor");
            if (findResource != null)
                MetroColors.PaletteInstance.AccentColor = (Color)findResource;

When I run my application. So I get this error:

Hi,

I need to populate the dropdown menu available at the bottom of the Radoutlooktoolbar. The idea is to provide menus and submenus when the user clicks the dropdown menu (the small inverted triangle) currently am totally unable to do that. I used ItemDropDownContentTemplate to accomplish this. I used the following code snippet.

 

<

 

 

telerik:RadOutlookBar x:Name="RadOutlookBar1"

 

 

 

MaxWidth="760" ItemsSource="{Binding}"

 

 

 

ItemTemplate="{StaticResource BarTemplate}"

 

 

 

ContentTemplate="{StaticResource redefineoutlook}"

 

 

 

TitleTemplate="{StaticResource BarTemplate}"

 

 

 

Margin="0,0,330,0" ItemDropDownContentTemplate="{StaticResource BarTemplate}">

I am successfully able to populate the Itemtemplate,Content template and the Title templates however the ItemDropdownContentTemplate is the missing link.
Bartemplate is something like below:

 

 

 

 

<DataTemplate x:Key="BarTemplate" >

 

 

 

 

<TextBlock Text="{Binding Path=A}" FontWeight="Bold" />

 

 

 

 

</DataTemplate>

Note:This template works fine in Titletemplate, ItemTemplate. Have no clue why it is not working in ItemDropdownContentTemplate. Kindly advise me where am wrong. Also let me know if there is anyother way to accomplish my requirements. This is rather urgent I need to do this ASAP.

Using Telerik WPF for .NET 4

OS: Windows Server 2008

Assuming a RadGridView named "grid" is defined in XAML the following code works in

WPF Version 2011.2.712.40 but not in later versions such as 2011.2.920.40 or 2011.2.1010.40.

Calling grid.Rebind() however works for all versions.

Expected result:

Calling mi1_Click should update the value in the first cell of the grid.

public partial class MainWindow : Window

    {

        private ObservableCollection<MyDynamicObject> myObjects;

        private int Counter;

          

        public MainWindow()

        {

            InitializeComponent();

            myObjects = new ObservableCollection<MyDynamicObject>();

            for (int i = 0; i < 5; i++)

            {

                dynamic myObject = new MyDynamicObject();

                myObjects.Add(myObject);

            }

            GridViewDataColumn col = new GridViewDataColumn();

            col.Header = "Prop1";

            col.DataMemberBinding = new Binding("Prop1");

            col.DataType = typeof(string);

            grid.Columns.Add(col);

            grid.ItemsSource = myObjects;

        }

  

        private void mi1_Click(object sender, RoutedEventArgs e)

        {

            MyDynamicObject myObj = myObjects[0];

            Counter++;

            myObj.PropertyDict["Prop1"] = Counter.ToString();

            myObj.NotifyPropertyChanged("Prop1");

        }

    }

  

    public class MyDynamicObject : DynamicObject, INotifyPropertyChanged

    {

        public readonly Dictionary<string, object> PropertyDict;

        public event PropertyChangedEventHandler PropertyChanged;

  

        public void NotifyPropertyChanged(string propertyName)

        {

            if (PropertyChanged != null)

                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

        }

          

        public MyDynamicObject()

        {

            PropertyDict = new Dictionary<string, object>();   

        }

         

        public override bool TryGetMember(GetMemberBinder binder, out object result)

        {

            string propertyName = binder.Name;

            object obj1;

            result = null;

            if (PropertyDict.TryGetValue(propertyName, out obj1))

                result = obj1;

            return true;

        }

  

        public override bool TrySetMember(SetMemberBinder binder, object value)

        {

            string propertyName = binder.Name;

            PropertyDict[propertyName] = value;

            return true;

        }

    }

Hi,
How can I populate a StackedArea1003D chart at code behind?
I have a collection of Date(x axis), Price(y axis) and Delta(z axis) to show on chart.

Hi,

shouldn't the RadContextMenu ensure on opening that the focus is within the attached element (or a child of it) in order to ensure that routed commands are working properly ?
Lets say I've two controls A and B.
Control B has a RadContextMenu set and contains a listbox.
The context menu contains one item "Copy" with the corresponding ApplicationCommands.Copy command set.
Control B has class command handlers for the Execute and CanExecute events of the ApplicationCommands.Copy command set.

Now if  control A receives the focus, you can still open the context menu for control B by simply right-clicking on it.
But the "Copy" menu item is now always disabled, since without the focus, the CanExecute and Execute event handlers of Control B are never called, so nobody listens on CanExecute in this case => the command is disabled.

If you left click on B's listbox and then open the context menu via right click, everything works properly, since now the listbox or it's item has the focus and CanExecute event walks up to control b.

Did I overlook something or do I really need to handle the RadContextMenu.ContextMenuOpening event manually and check whether to set the focus or not ?

Thanks in advance
