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:

System.Windows.Markup.XamlParseException occurred
  Message=Set property 'Telerik.Windows.Controls.LocalizationManager.ResourceKey' threw an exception.

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

I tried restyling the RadDocking ToolWindows. So I followed the instructions, created a dummy control with a RadDocking in it. copied a ToolWindow Style to a ResourceDictionary.

However now I end up with an error

Error 1 The type reference cannot find a public type named 'RadDockingTheme'.

The error refers to
 <Style x:Key="{telerik:ThemeResourceKey ThemeType={x:Type local:RadDockingTheme}, ElementType={x:Type telerik:ToolWindow}}" TargetType="{x:Type telerik:ToolWindow}">

I Have an empty class like this :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Telerik.Windows.Controls;

namespace RadControlsWpfApp1
{
    public class RadDockingTheme:Theme
    {
    }
}

and added xmlns:local="clr-namespace:RadControlsWpfApp1;assembly=RadControlsWpfApp1" before the style definition.

Can somebody tell me waht is wrong or post the source code of a working example of a restyled radpane toolbox?

Thanks in Advance!

Is it possible to bind and a funtion to "Add New Criteria" and "Delete" buttons onClick event?

Or an alternative event that fires everytime a new Filter Criteria or Nested Operator is added?

Hello Telerik Team,

I have a requirement where the rad combobox has a list of names. After selecting a value from the dropdown panel, the selected name should be displayed as a hyperlink.
I have managed to get the hyperlink by using a DataTemplate in the SelectionBoxTemplate of the radcombobox as shown below.

 

But the click event of the hyperlink doesn't get's fired, nor does the cursor pointer changes to hand cursor on hovering over the selected value as it does for a normal hyperlink.

Is there a solution to achieve this requirement.

Thanks.

Regards,
Mausami.

is there any documentation for this new control

cheers
