Hi,

I am trying to set a method to be called when the selected value of a GridViewComboBoxColumn is changed.

I have read about it on http://docs.telerik.com/devtools/wpf/controls/radgridview/columns/how-to/selectionchanged-comboboxcolumn and tried to implement it.

Here is my code:

However, I am getting an error:

"Expected a method with 'void OnSelectionChanged(object, SelectionChangedEventArgs signature".

If I get rid of my OnSelectionChanged() method and use the suggestions given, it gives me:

Can someone please explain why this is not working for me?

Thank you

Hi

I'm trying to implement RadDocking using DockingPanesFactory as per your examples (like this one).

I have set the PaneSource to a collection of viewmodels e.g. MyViewModel which has a property "Name".

I would like to bind the RadPane header to the "Name" property on the viewmodel. Ideally I would like to have a custom DataTemplate as well but I will settle for just getting the value to update with the ViewModel.

The CreatePaneFromItem method states that "...set any of the DataContext, Header, Title or Content based on the item as well as Style with bindings in the style setters to bind properties of the item to properties of the RadPane" however nothing I've tried seems to work.

I've tried setting a style with the setter properties like this:

var pane = new RadPane();
pane.DataContext = (MyViewModel)item;

Style style = new Style();
style.TargetType = typeof(RadPane);
Setter setter = new Setter();
setter.Property = RadPane.HeaderProperty;
setter.Value = new Binding("Name")
pane.Style = style;

Ideally I'd like to define a DataTemplate in a ResourceDictionary and retrieve and set that to the pane header but I'm not sure how to get that resource in the DockingPanesFactory

Can you offer any advice?

Hello,

Is it possible to highlight the default button on a text input dialog? As per: 

Focus is on the text input and I can type, but Save is highlighted and clearly the default when hitting enter. Note that when you tab through to Cancel, Save is no longer highlighted and cancel is - this is the behaviour I would like to implement.

Is there a way of building a dialog with input text and highlighting the default button? For a normal dialog with a message and no text input, setting the button as the FocusedElement suffices, but that will not work for the case with an input.

Cheers

I am trying to implement function similar to a Acount info in Visual Studio in my App build On RibbonWindow/RibbonView(WPF).

Somethink like this:

Controls do not get focus if the RibbonWindow is not Maximzed. If it is Maximzed they get focus only if mouse enters from bottom side.

Here is small reproducer .

Do I miss some setting in RibnbonWindow/RibbonView? Is it Posible with Telerik Framework?   

Hi,

Context:

- TextBox in a Popup

- Type using the RadVirtualKeyboard

- Keyboard is set to Japanese

After making sure the TextBox has the popup and then starting to use the Keyboard in Hiragana, the IME suggestions are shown in the top left corner of the screen instead above the TextBox.

Code:

<telerik:RadVirtualKeyboard Margin="10,119,436,58"/>
<Popup Width="100" Height="100" IsOpen="True">
	<StackPanel Background="Red">
		<TextBox></TextBox>
	</StackPanel>
</Popup>

Using the RadVirtualKeyboard:

Using real keyboard or windows intergrade ok screen keyboard:

Is there a way to solve this issue?

Thanks a lot!

Hi Stenly,

I think this is my last question.
Then I'll will finish my PoC with the Telerik WPF controls.

Now I still know that I have to build my application with the Telerik controls without the embedded XAML.

I have still a problem to run the Docking controls with PRISM 8 without the XAML libs.
With the XAML libs everything ist fine.

My demo projects:

1.) Prism 8 default solution from Brian Lagunas template pack extended by the Telerik solution of using Docking with Prism 7 (from Telerik SDK Samples Browser).
Samles is using the embedded XAML version.
=> Everything works fine
Please have a look at the attached image

2.) Prism 8 default solution from Brian Lagunas template pack extended by the Telerik solution of using Docking with Prism 7 (from Telerik SDK Samples Browser).
Samles isn't (!) the embedded XAML version.
=> The RadDocking header are missing.
Please have a look at the attached image

I think I'm still missing to set any style somewhere.

Thanks 

Dirk

Is there a 

telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True" that works on the RadListBox (not only the RadComboBox)?

So a :ComboBoxToolTipHelper.ShowToolTipOnTrimmedText that works on the RadListBox?

Or another way of achieving it on the RadListBox?

Background:

I tried with a behavior on the row data template but it conflicts with the drag and drop by causing exceptions during the drag and drop (but that would incur another question thread).  I am just writing this to say i tried this avenue.

Right now my RadLitBox looks as follows:

<telerik:RadListBox x:Name="RLB_Source"   
                                        VerticalAlignment="Stretch" HorizontalAlignment="Stretch"
                                        ItemsSource="{Binding SourceSplitList, Mode=TwoWay}" 
                                        SelectionMode="Multiple"  
                                        telerik:ListBoxSelectedItemsBehavior.SelectedItemsSource="{Binding SelectedSourceItems}"
                                        DisplayMemberPath="Name" 
                                        AllowDrop="True" 
                                        ScrollViewer.HorizontalScrollBarVisibility="Disabled"
                                        ScrollViewer.VerticalScrollBarVisibility="Visible"  
                                        Style="{StaticResource RadListBoxStyle}" 
                                        telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
                                        ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}" 
                                        >

Because of the lines:

                                        telerik:ComboBoxToolTipHelper.ShowToolTipOnTrimmedText="True"
                                        ToolTipService.ToolTip="{Binding Text, RelativeSource={RelativeSource Self}}" 

There is a tool tip showing the text of every RadListBox row - and not only where the text is trimmed.

How is the text trimmed? Short answer: i have a telerik:RadListBoxItem style template where text trimming is set as below:  

         <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>

Here is the entire control template:

 <ControlTemplate TargetType="{x:Type telerik:RadListBoxItem}">
                    <Border
                                x:Name="Bd"
                                Padding="{TemplateBinding Padding}"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                SnapsToDevicePixels="true">
                        <ContentPresenter 
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                   SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                                   >

                            <ContentPresenter.Resources>
                                <Style TargetType="TextBlock">
                                    <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>
                                    <Setter Property="TextWrapping" Value="NoWrap" />
                                    <Setter Property="Text" Value="{Binding Name}" />
                                    <Setter Property="ToolTipService.ToolTip" Value="{Binding Name}" />
                                </Style>
                            </ContentPresenter.Resources>
                        </ContentPresenter> 
                    </Border>  

</ControlTemplate>

Trimming is set on the TextBlock that appears (implicitly by Telerik) in the Contentpresenter.

The whole styling is below if relevant for answering the question:

My RadListBox has this style:

 <Style x:Key="RadListBoxStyle" TargetType="{x:Type telerik:RadListBox}">
        <Setter Property="AlternationCount" Value="2" />
        <Setter Property="ScrollViewer.CanContentScroll" Value="True" />
        <Setter Property="VirtualizingPanel.ScrollUnit" Value="Pixel" />
        <Setter Property="VirtualizingPanel.VirtualizationMode" Value="Recycling" />
        <Setter Property="BorderThickness" Value="1" />
        <Setter Property="BorderBrush" Value="{StaticResource Gray}" />
        <Setter Property="Background" Value="{DynamicResource White}" />
        <Setter Property="SelectionMode" Value="Multiple" />
        <Setter Property="FontSize" Value="12pt" />
        <Setter Property="FontFamily" Value="{StaticResource SourceSansPro-Regular}" />
        <Setter Property="Foreground" Value="{StaticResource Brand Default}" />
        <Setter Property="Margin" Value="0,2,0,0" />
        <Setter Property="HorizontalAlignment" Value="Stretch" />
        <Setter Property="ItemContainerStyle" Value="{StaticResource DefaultDragDropRadListBoxItemStyle}" /> 
    </Style> 

In the the above style there is an ItemContainerStyle.  Here it goes:

  <Style x:Key="DefaultDragDropRadListBoxItemStyle" TargetType="telerik:RadListBoxItem">
        <Setter Property="BorderBrush" Value="{StaticResource 'Gray Light'}" />
        <Setter Property="BorderThickness" Value="0,0,0,1" />
        <Setter Property="telerik:DragDropManager.AllowCapturedDrag" Value="True" /> 

        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type telerik:RadListBoxItem}">
                    <Border
                                x:Name="Bd"
                                Padding="{TemplateBinding Padding}"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}"
                                SnapsToDevicePixels="true">
                        <ContentPresenter 
                                   HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                                   VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                                   SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"
                                   >

                            <ContentPresenter.Resources>
                                <Style TargetType="TextBlock">
                                    <Setter Property="TextTrimming" Value="CharacterEllipsis"></Setter>
                                    <Setter Property="TextWrapping" Value="NoWrap" />
                                    <Setter Property="Text" Value="{Binding Name}" />
                                    <Setter Property="ToolTipService.ToolTip" Value="{Binding Name}" />
                                </Style>
                            </ContentPresenter.Resources>
                        </ContentPresenter>

We have created an app that allows the user to create templates using the diagram control, and then bind data (several records) to print / export to PDF.  The bind operation does not need the diagram to be visible, and its a desired behavior, the user can click a button and we work with the diagram in the background (bind each record, export the image) without the user seeing the diagram loading every record.

The issue we have encountered is that if the diagram has collapsed visibility or is not visible, the items do not render (they have their isLoaded property set to false). This might be an optimization on the Diagram to render only visible items, however its causing an issue for our use case. 

How do we make the diagram load and render all items even when its not visible?  (Or what trick can we use to keep the diagram hidden and yet have it render?)

We also wish to optimize the loading speed in this scenario, suggestions to speed up diagram loading saved items would really help us, as you can imaging we do not need any UI features such as Dragging, Copy/Paste/Undo etc. in the data-bind and export mode.
