Hi,

i have a GridView binded to an observable collection of "items" and its SelectedItem property binded to an item in the ViewModel.

Example to explain the behavior that I want to avoid:

I have 3 items in the collection and in the grid I've selected the second row, corresponding to the second element of the collection.
If I add a new element in the collection, the gridview automatically adds a new row for it (and thats ok) and select this new row (which is not ok for me, in this case I want to keep the selection on the second row)

Any idea to achieve this?

Thanks

John

I'm trying to figure out how to use a Telerik ListBox control for an application that I'm writing. For some reason I can't view any of the Telerik demos (they're all timing out on me), and so I've been searching around this site for other help. I came across this page on drag-and-drop for the ListBox, and it looks really promising. However, in reading through the code on the page I came across their ProductToOrderConverter class. It inherits (or implements, I'm not sure which) from something called a DataConverter. What is that?? Even on this site I'm having a hard time finding any documentation on what the dataconverter class/interface is.

Is there a built in method (or plans to implement) to lock tiles assigned to a particular group from being dragged to another group?  For instance, say I have a series of tiles associated with the group Music, and another series of tiles associated with the group Movies.  I would like to prevent these tiles from being moved between groups.

Hi,

It's the first time I'm using Implicit Styles and NoXaml so I'm sure I'm doing something wrong and I hope someone can help me. 

I have a Prism project. At main WPF application project, I have added references for all dll I need in all modules. Currently, I've added the following ones:
Telerik.Windows.Controls;
Telerik.Windows.Controls.Charts;
Telerik.Windows.Controls.Data;
Telerik.Windows.Controls.Input;
Telerik.Windows.Controls.Navigation;
Telerik.Windows.Controls.ScheduleView;
Telerik.Windows.Data;

At this project, at App.xaml I've merged the following xaml files (the xaml files Telerik WPF extensions added at Themes folder
<ResourceDictionary.MergedDictionaries>
                 
                <!-- Telerik.Windows.Controls is used by all assemblies -->
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.xaml" />
 
                <!--<ResourceDictionary Source="Themes\Windows8Touch\System.Windows.xaml" />-->
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Input.xaml" />
 
                <!-- Requires: System.Windows.xaml -->
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Navigation.xaml" />
 
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Chart.xaml" />
 
                <!-- Requires: Telerik.Windows.Controls.Input -->
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.Data.xaml" />
                
                <!-- Requires: System.Windows, Telerik.Windows.Controls.Input, Telerik.Windows.Controls.Navigation -->
                <ResourceDictionary Source="Themes\Windows8Touch\Telerik.Windows.Controls.ScheduleView.xaml" />
                 
            </ResourceDictionary.MergedDictionaries>


Now, I have one module (in a separated project) that has references to:
Telerik.Windows.Controls;
Telerik.Windows.Controls.Data;
Telerik.Windows.Controls.Input;
Telerik.Windows.Controls.Navigation;
Telerik.Windows.Data;

One of the Views in this module contains a RadDataform but it's DataFields are not visible when View appears at UI. I've tried to use DataFormDataField control alone with no success. Am I missing something?

Thanks.

I'v setup applied a custom style to a RadAutoCompleteBox in order to change its visual design. I would also like to customize its RadAutoCompleteBoxItems (e.g. change the RemoveButton). How can this be achieved?

I found a RadAutoCompleteBoxItemStyle in the built-in Themes but it seems like this style is set globally. Which property of the RadAutoCompleteBox can I use to override this default style?

Thanks for your help

Hi all of you,

I'm using this control under trial license. I'm trying to do a very simple binding but it doesn't work at all:

xaml header:

Here you can see the reference to one of my RESX files (I've got one for English and another one for Spanish where every key is named alike.
Names of resources files:

MasterGIT.resx and MasterGIT.en.resx

This line uses one RESX under criteria language:

     ResxExtension.DefaultResxName="GIT_CuadroMando.MasterGIT" Language="{UICulture}"

 

 

<Window

        ResxExtension.DefaultResxName="GIT_CuadroMando.MasterGIT" Language="{UICulture}"

    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"  x:Class="GestorDocumental"

 

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Loaded="Window_Loaded"

    xmlns:local="clr-namespace:GIT_CuadroMando"

    xmlns:commands="clr-namespace:Telerik.Windows.Media.Imaging.ImageEditorCommands.RoutedCommands;assembly=Telerik.Windows.Controls.ImageEditor"       

    xmlns:tools="clr-namespace:Telerik.Windows.Media.Imaging.Tools;assembly=Telerik.Windows.Controls.ImageEditor"

    Title="{Resx TitleGestorDocumental}" Height="701" Width="1000" ResizeMode="CanResize" WindowStyle="ToolWindow">

 

 

<telerik:RadImageEditorUI x:Name="BodyWorkAndPaintingTool" Grid.ColumnSpan="4" Margin="10,49,33,10" Grid.Row="1" Grid.RowSpan="4">

          <telerik:RadImageEditorUI.ImageToolsSections>

              <telerik:ImageToolsSection Header="{Resx Disenador_Blur}"  >

 

                  <telerik:ImageToolItem ImageKey="Resize" Text="Resize" Command="commands:ImageEditorRoutedCommands.ExecuteTool">

                      <telerik:ImageToolItem.CommandParameter>

                          <tools:ResizeTool x:Name="resizeTool"/>

                      </telerik:ImageToolItem.CommandParameter>

                  </telerik:ImageToolItem>

 

                  <telerik:ImageToolItem ImageKey="Resize" Text="Canvas resize" Command="commands:ImageEditorRoutedCommands.ExecuteTool">

                      <telerik:ImageToolItem.CommandParameter>

                          <tools:CanvasResizeTool/>

                      </telerik:ImageToolItem.CommandParameter>

                  </telerik:ImageToolItem>

 

 
code-behind:

Private Sub Window_Loaded(sender As Object, e As RoutedEventArgs)

 

        CultureManager.UICulture = Thread.CurrentThread.CurrentCulture

'        Thread.CurrentThread.CurrentUICulture = New CultureInfo("es")

 

    End Sub

private void diagram_ConnectionManipulationCompleted(object sender, ManipulationRoutedEventArgs e)
{
     Here, e.Connector may be null. Why?!
}

Some times, when I drag a connection from a node and then release it before attaching to another connector, the ConnectionManipulationCompleted event is fired with its Connector set to null. It happens maybe 1 out of 10 tries, but after it has occurred it seems to happen more often until I press ESC or perform some other reset operation.

How should I interpret this? Is it a bug or is this a valid state?

UPDATE:
This event is usually not fired when I do the above. Only when it does indeed fire, this weird state is seen. I believe this event is erroneously called from within your code. Also, e.ManipulationStatus is set to ManipulationStatus.Moved. Obviously, I did not move a connection...

In all the built in .net WPF controls, you may override the default style, and specify your own custom template.  In my usage, it allows me to view a Textbox as a Label, have a button clicked to switch the mode to Edit mode, and switch the style to change the control back to a TextBox.

When I attempt to do the same thing for the Telerik - RadAutoCompleteTextbox, with this style, I get the following error (view mode)

<Style x:Key="RadAutoCompleteBoxViewMode" TargetType="{x:Type telerik:RadAutoCompleteBox}">
        <Setter Property="OverridesDefaultStyle" Value="True" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type telerik:RadAutoCompleteBox}">
                    <Label Content="{Binding SearchText, RelativeSource={RelativeSource AncestorType=telerik:RadAutoCompleteBox}}" Style="{StaticResource FormFieldReadOnly}" />
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

Object reference not set to an instance of an object.
   at Telerik.Windows.Controls.RadAutoCompleteBox.InitializeBoxesItemsControl() in c:\TB\135\WPF_Scrum\Release_WPF\Sources\Development\Controls\Input\AutoCompleteBox\RadAutoCompleteBox.cs:line 1067

Is there something I'm missing?  Is there another way to accomplish this goal ?  Should not the concept of lookless controls be supported?  

thanks!
