Just crash with

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

Do you have any means for a variety of UI color expresion?

Your color Themes (VisualStudio 2013,Office2013,Windows 8 touch,Windows 8,Expression Dark, ... e.t.c) give not very rich color expression. For example, RadTreeListView is looked as in RadTreeListView.PNG file attached. What about your Green Theme - it is somewhat dark. Do you have any means for a variety of coloring?

SelectedItem reset when unloading?

I have a RadAutoCompleteBox in RadGridView CellEditTemplate

public class AutoCompleteCell : RadAutoCompleteBox

{

public AutoCompleteCell()

{

SelectionMode = AutoCompleteSelectionMode.Single;

Unloaded += unloaded;

Loaded += loaded;

}

private void loaded(object sender, RoutedEventArgs e)

{

//all has value

string searchText = SearchText;

object selectedItem = SelectedItem;

}

private void unloaded(object sender, RoutedEventArgs e)

{

string searchText = SearchText; //has value

object selectedItem = SelectedItem; //no value

}

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.

<controls:AutoCompleteCell SelectedItem="{Binding Value, Mode=TwoWay}" ItemsSource="{Binding Source, Mode=OneWay}" SearchText="{Binding Header, Mode=OneWay}" />

"Header" is returned from "Value".

RadComboBox with RadGridView

I would like to have a combobox that displays a text value when an item is selected but displays a grid with headers when the user clicks on the combobox (see attachment). I used the SelectionBoxTemplate to set the selected item text value and created a comboboxitem with a radgridview inside of it. I cannot use the SelectionBoxTemplate with the radgridview. Is there something wrong with how I have it setup? Also, the radgridview does not update the combobox when an item is selected? How can I make this function like a normal combobox? I don't need autocomplete.

<telerik:RadComboBox SelectionBoxTemplate="{StaticResource SelectionBoxTemplate}"
IsEditable="True" Height="25" Width="200">
<telerik:RadComboBox.Items>
<telerik:RadComboBoxItem>
<telerik:RadComboBoxItem.Template>
<ControlTemplate>
<telerik:RadGridView x:Name="RadGridView1" ShowGroupPanel="False" CanUserFreezeColumns="False"
RowIndicatorVisibility="Collapsed" IsReadOnly="True"
IsFilteringAllowed="False" ItemsSource="{Binding Tools}"
Width="200" Height="150" SelectedItem="{Binding Assignment, Mode=TwoWay}" AutoGenerateColumns="False">
<telerik:RadGridView.Columns>
<telerik:GridViewColumn Header="Item #" HeaderCellStyle="{StaticResource GridViewHeaderCellDefault}">
<telerik:GridViewColumn.CellTemplate>
<DataTemplate>
<TextBlock Style="{StaticResource TextBlockDefault}" Text="{Binding ItemNumber}" />
</DataTemplate>
</telerik:GridViewColumn.CellTemplate>
</telerik:GridViewColumn>
<telerik:GridViewColumn Header="Tool Name" HeaderCellStyle="{StaticResource GridViewHeaderCellDefault}">
<telerik:GridViewColumn.CellTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Style="{StaticResource TextBlockDefault}" Text="{Binding ToolName}"/>
</StackPanel>
</DataTemplate>
</telerik:GridViewColumn.CellTemplate>
</telerik:GridViewColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
</ControlTemplate>
</telerik:RadComboBoxItem.Template>
</telerik:RadComboBoxItem>
</telerik:RadComboBox.Items>
</telerik:RadComboBox>

Display 1 values with logarithmic scale

Hi, I'm struggling with a small display issue:

I have a bar chart with logarithmic Y scale. Evetyng is ok but if a bar has the value of 1 is not displayed. And this is correct because the logarithm of 1 is 0.
So there is no difference between a bar is not present and a bar with value 1.

I tried to set the minimum value of 0.5 but it's only displayed a gap between the X axis and the bars.

Is there a way to display small Bar when the values is 1? Like setting a small border or a padding?

TransitionControl (or TransitionPresenter?) in a Frame

Hi,

I'm trying to replace the ContentPresenter in a Frame with the TransitionControl as described here:

http://docs.telerik.com/devtools/wpf/controls/radtransitioncontrol/features/radtransition-integration-with-content-controls

If I follow this example, no content is displayed.

I also tried using TransitionPresenter, which is better in that the content does show up, but there are no transition animations?

I have successfully used a TransitionControl stand-alone, but I'm hoping to use the navigation features of Frame along with transition animations.

What am I doing wrong?

<Frame x:Name="NavFrame" NavigationUIVisibility="Visible" Margin="0,50,0,0">

<Frame.Template>

<ControlTemplate TargetType="{x:Type Frame}">

<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="{TemplateBinding Padding}">

<teleriktp:TransitionPresenter CurrentContent="{TemplateBinding Content}" Duration="0:0:3">

<teleriktp:TransitionPresenter.Transition>

<telerikTransitions:WaveTransition />

</teleriktp:TransitionPresenter.Transition>

</teleriktp:TransitionPresenter>

</Border>

</ControlTemplate>

</Frame.Template>

</Frame>
