I'm trying to display some of the Data as Text in my TimelineItems, but all my Template can access is an Object of type TimelineDataItem

System.Windows.Data Error: 40 : BindingExpression path error: 'Iteration' property not found on 'object' ''TimelineDataItem'

TimelineDataItem has no Property that holds the original value object. In the ToolTip I can access the original Data object, though.
Can anyone tell me please how I can get the original Data in the template?

                                        <ControlTemplate TargetType="{x:Type telerik:TimelineItemControl}">
                                            <Border Background="#01FFFFFF" Height="30" Margin="0,5,0,0">
                                                <Grid>
                                                    <Rectangle x:Name="timelineItem" Height="29" Stroke="#FFCBCBCB" VerticalAlignment="Center">
                                                        <Rectangle.Fill>
                                                            <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                                                                <GradientStop Color="#FF4786AA" Offset="0"/>
                                                                <GradientStop Color="#FF163D59" Offset="1"/>
                                                            </LinearGradientBrush>
                                                        </Rectangle.Fill>
                                                    </Rectangle>
                                                    <TextBlock Text="{Binding Path=Iteration.Name}"></TextBlock>
                                                </Grid>
                                            </Border>
                                        </ControlTemplate>

Hey guys
I am newbie in Telerik WPF Dev, I have a trouble with implementation of telerik already prepared examples. For example here is one link

http://demos.telerik.com/silverlight/#GridView/Selectors/StyleSelectors/RowStyleSelector

Under the code we can notice

xmlns:Examples="clr-namespace:Telerik.Windows.Examples"

and further down xaml tag

<Examples:UnitPriceConveter x:Key="converter" />

How to get access to that 'Examples',
how to implement the example to make it work with my DataTable as my DataSource.
I could not find any info of how to make these examples to work with DataTable.

If you will explain or provide at least one example of how to go around that 'Examples:' tag and of how to use DataTable as DataSource I will be ok

Thanks
 

I have a RadDataForm that contains a number of fields.

When I add a DataFormDateField and bring up the form in ReadOnly mode, the field is disabled.  When I add a DataFormDataField that contains a RadDateTimePickerand bring up the form in ReadOnly mode, the field is not disabled.

In other words, this works:

And this does not:

Is there a way to get a DataFormDataFields contained controls to respond to the form's Mode?

Hi,

The following works when the context menu is declared in the TreeView directly.

However when placed my context menu inside the Data template as I only want a context menu with leave items,

it does not work anymore. I tried to change the binding with the relativesouce but no luck. we are using the MVVM. The commands are in the ViewModel of the view.

Do you have any examples with it?

Thanks

Hi,

I experienced a problem in my developing the WPF application. The application consists of a RadScheduleView and many WPF Hyperlink items. Once the ScheduleView is on focus, then I click on any Hyperlink, the application hangs and shows "InvalidOperationException" in Debug mode, saying that Hyperlink is not a Visual or Visual3D.

Full stacktrace is captured as follow:

There will be no error if I click other UI element (e.g. TextBox) after ScheduleView is on focus.
And I cannot find the way to catch the Exception, thus the application will hang once user click on Hyperlink after ScheduleView is on focus.

Is that a bug?
Thanks a lot!

Hi. I implement IDataErrorInfo in my ViewModel's class. I use RadDataForm that bind to simple source from viewmodel. When i start project i have exception (TargetParameterCountException Parametr count mismatch). What is wrong?

Hi,

we would like to create a CustomControl that derives from a RadComboBox with a special ItemTemplate. On our first approach we tried it with a usual combox by adding to following lines to the Generic.xaml file of the project:

<Style TargetType="{x:Type local:ComboBoxLookupDataMaterialMainGroups}" BasedOn="{StaticResource {x:Type ComboBox}}">

    <Setter Property="ItemTemplate">

        <Setter.Value>

            <DataTemplate >

                 Individual Template Definition

            </DataTemplate>

        </Setter.Value>

    </Setter>

</Style>

It worked as expected so we changed the baseclass of the custom control to a RadComboBox, searched for the correct "BasedOn" content and changed it to:

Because the RadComboBoxStyle was unknown, we also added the implicit theme XAMLs

• Telerik.Windows.Controls.XAML and
• Telerik.Windows.Controls.Input.XAML

to the project's theme folder and added the following includes to the Generic.XAML:

The whole project is just a WPF control assembly that is used by another WPF application project, so it doesn't contain an App.xaml file.

After starting the application it hangs with a XAMLObjectWriterException: Zeilennummer "7" und Zeilenposition "10" von "Beim Festlegen der Eigenschaft "System.Windows.ResourceDictionary.Source" wurde eine Ausnahme ausgelöst.".

Maybe it's just a small missing piece but it also might be a fundamental lack of knowledge since we are new to WPF. Could you please help us out?

Thanks!
