GridViewHeaderCell

Greetings-
I have been trying for some time now to style the GridViewHeaderCell of the RadGridView. I have been attempting to follow the instructions on:
http://www.telerik.com/help/wpf/telerik.windows.controls.gridview-telerik.windows.controls.gridview.gridviewheadercell.html
Unfortunately, there seems to be an issue with the instructions...

In order to expose the GridViewHeaderCell class you need to declare

public class GridViewHeaderCell : GridViewCellBase, IColumnInfo, IProvideGridViewColumn

The GridViewHeaderConstructor should initialize a new instance of the GridViewHeaderCell class.

public GridViewHeaderCell()

Also the IProvideGridViewColumn which has been mentioned seems to be deprecated, where do we declare the GridViewHeaderCell? MainWindow.xaml? AppResources.xaml?

Thanks,

GridView

DataFormCheckBoxField label missing and alignment issue

<StackPanel>
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.AccountName, Mode=TwoWay}"
          Label="Account:" />
 
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.Username, Mode=TwoWay}"
          Label="Username:" />
 
     <telerik:DataFormDataField
          Label="Old Password:">
               <PasswordBox />
     </telerik:DataFormDataField>
 
     <telerik:DataFormDataField
          Label="New Password:">
          <PasswordBox />
     </telerik:DataFormDataField>
 
     <telerik:DataFormDataField
          DataMemberBinding="{Binding Credential.Domain, Mode=TwoWay}"
          Label="Domain:" />
 
     <telerik:DataFormCheckBoxField
          DataMemberBinding="{Binding Credential.IsPrimary, Mode=TwoWay}"
          Label="Is Primary:" />
</StackPanel>
This is a DataTemplate I'm applying to my RadDataForm.  However, that last CheckBox field is not displaying properly.  

Here is a photo link showing what the output looks like:

I'm using the latest internal release of the WPF controls on trial.  Any ideas?

[Solved] DataBinding with Custom Tabs

I have a databound tabstrip where the tabs come from one set of data and the content of the tabs is a DataTemplate with a ListView inside. Is there a way to have this scenario but also add additional tabs for items that will not be bound to that DataTemplate?

My tabstrip XAML looks like this:

<telerik:RadTabControl telerik:Theming.Theme="Windows7" BackgroundVisibility="Collapsed" TabStripPlacement="Left" TabOrientation="Vertical" DisplayMemberPath="Name"

ItemsSource="{Binding ReviewCategoryModels}" ContentTemplate="{StaticResource ReviewSectionDetailTemplate}" Align="Right" ItemContainerStyle="{StaticResource ReviewCategoryTabStyle}" />

And then in UserControl.Resources I have the following:

<DataTemplate x:Key="ReviewSectionDetailTemplate">

<ListView x:Name="items" ItemsSource="{Binding Items}" AlternationCount="2" MinWidth="550" Style="{StaticResource ReviewItemListView}">

[...]

</ListView>

</DataTemplate>

So I want to use this setup but then add an additional tab (or two, etc.) that do NOT use this DataTemplate. My app is based off the MVVM pattern so sticking inside the guidelines of that is preferable (though not required).

Is this possible?

radribbonview vs radribbonbar

Hi,
It appears there are only a couple differences between RadRibbonView and RadRibbonBar as follows:

RibbonView implements MS Office 2010 UI.
- Although the on-line docs tend to say Office 2007:
  - http://www.telerik.com/help/wpf/radribbonview-overview.html
  - http://www.telerik.com/help/wpf/radribbonview-key-features.html
RibbonView includes "Codeless Test Automation for Scheduler."
RibbonView is newer.

Are there other differences I'm missing?
How do these 2 compare with RadRibbonWindow?

Thank you,
- Martin Schneider

Custom operator selection

Hi,

is it possible to select available operators for a specific property (type)? I clarify this request: I have some flags enumerations in my business objects. I would like to filter objects by these flags enumerations. If you have a flags enum with following members: First = 1, Second = 2, Third = 4. And you want to filter all objects which have value "Second" set. The default operators for enum types are "Equal" and "Is not equal". But for the flags enumerations the correct questions would be additional "contains" and "not contains". I know how to implement a DropDown with Checkboxes for specific flag selection to make a graphical representation of this question. But how is it possible to add the two more operators "contains" and "not contains" to the list of available operators? And how could I implement user defined code "behind" this operators?

Best regards,
Oliver

Richtext box not selecting proper span text

I ve created span form code behind see the code:

public MainWindow()

{

InitializeComponent();

Telerik.Windows.Documents.Model.Section section = new Telerik.Windows.Documents.Model.Section();

Telerik.Windows.Documents.Model.Paragraph paragraph = new Telerik.Windows.Documents.Model.Paragraph();

Telerik.Windows.Documents.Model.Span span = new Telerik.Windows.Documents.Model.Span("span1. dfgfdgfd ");

Telerik.Windows.Documents.Model.Span span2 = new Telerik.Windows.Documents.Model.Span("span2.");

paragraph.Inlines.Add(span);

paragraph.Inlines.Add(span2);

section.Blocks.Add(paragraph);

radRichTextBox1.Document.Sections.Add(section);

}

on selection of current span using GetCurrentSpanBox().Text when the cursor is on "dfgfdgfd " i should get this "span1. dfgfdgfd " but i m getting "dfgfdgfd" this only. it recognize "SPACE" as a span. why?

private void radRichTextBox1_MouseUp(object sender, MouseButtonEventArgs e)

{

textBox1.Text = radRichTextBox1.Document.CaretPosition.GetCurrentSpanBox().AssociatedSpan.Text;

}

[Solved] How to reuse Legend definition

Hi,
I want to use the same legend on several graph without duplicate xaml everywhere but when i do this the legend is displayed only in one chart :

the definition of my legend:

<telerik:ChartLegend x:Uid="ClassificationLegend"

x:Key="ClassificationLegend"

Name="ClassificationLegend"

Visibility="Visible"

Header=""

Padding="0,0,5,0"

HorizontalContentAlignment="Right"

VerticalAlignment="Center"

BorderThickness="0"

Background="Transparent"

UseAutoGeneratedItems="False">

<telerik:ChartLegendItem x:Uid="telerik:ChartLegendItem_1"

Label="Success"

MarkerFill="{x:Static sim:ClassificationStatusColors.SuccessBrush}" />

<telerik:ChartLegendItem x:Uid="telerik:ChartLegendItem_2"

Label="Hesitation"

MarkerFill="{x:Static sim:ClassificationStatusColors.HesitationBrush}" />

<telerik:ChartLegendItem x:Uid="telerik:ChartLegendItem_3"

Label="Unknown"

MarkerFill="{x:Static sim:ClassificationStatusColors.UnknownBrush}" />

<telerik:ChartLegendItem x:Uid="telerik:ChartLegendItem_4"

Label="Misrecognition"

MarkerFill="{x:Static sim:ClassificationStatusColors.MisrecognitionBrush}" />

</telerik:ChartLegend>

The way i use it:

<telerik:RadChart Name="chartStrategyPerformanceMax"

Background="Transparent"

BorderThickness="0"

IsTabStop="False"

DataContext=

"{Binding RelativeSource={RelativeSource AncestorType=telerik:RadFluidContentControl, Mode=FindAncestor},  Path=DataContext}"

ItemsSource="{Binding StatusGroup}"

PaletteBrushes="{Binding BrushPalette}">

<telerik:RadChart.SeriesMappings>

</telerik:RadChart.SeriesMappings>

<telerik:RadChart.DefaultView>

<telerik:ChartDefaultView ChartLegend="{StaticResource ClassificationLegend}">

<telerik:ChartDefaultView.ChartArea>

<telerik:ChartArea LegendName="ClassificationLegend"

SmartLabelsEnabled="True" />

</telerik:ChartDefaultView.ChartArea>

</telerik:ChartDefaultView>

</telerik:RadChart.DefaultView>

</telerik:RadChart>

and same in another chart:

<telerik:RadChart ItemsSource="{Binding DocumentsClassificationScore}"

PaletteBrushes="{x:Static sim:ClassificationStatusColors.ClassificationPalette}">

<telerik:RadChart.DefaultView>

<telerik:ChartDefaultView ChartLegend="{StaticResource ClassificationLegend}">

<telerik:ChartDefaultView.ChartArea>

<telerik:ChartArea LegendName="ClassificationLegend"/>

</telerik:ChartDefaultView.ChartArea>

</telerik:ChartDefaultView>

</telerik:RadChart.DefaultView>

...

I think because of the staticResource only one instance of the legend is created and this instance can only be owned by one chartarea (am i right ?).
But there is no LegendStyle and even i don't know a way to add LegendItem by style so, is there a way to not copy/paste the same lines in all my graph. A way in declarative xaml of course and without code behind...
