I have the need to extend the DatePicker. I try to do this as I have done when I have extended the standard WPF controls (e.g. TextBox), but I have some problems. I can't make my extended control use its own template.

The control has this code:

public class DatePickerExtended : RadDatePicker

{

static DatePickerExtended()

{

//Make sure the style in Themes/Generic.xaml is used.

DefaultStyleKeyProperty.OverrideMetadata(typeof(DatePickerExtended), new FrameworkPropertyMetadata(typeof(DatePickerExtended)));

}

Then I have a folder in the root called "Themes" which contains a file called "Generic.xaml". This XAML file contains the template that i want to apply to the control:

<Style TargetType="{x:Type local:DatePickerExtended}" x:Key="{x:Type local:DatePickerExtended}">

</Style>

But the template is never applied. Instead the default template for the DatePicker is used, and I don't now how to replace this with my own...

So the question is: How can I make my custom control inheriting from DatePicker use a custom template?

</Style>

</Window.Resources>

<Grid>

<telerik:GridViewDataColumn

Header="One"

Width="100"

/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

</Window>

How can I achieve this?

Thanks,

databind an ItemMapping FieldName

Hi, I have a chart in a view that I would like to use to display 3 different types of data in different instances of the view ...so in one instance the view may be displayed to show Commission and in another scenario the view may be used to display "Volume" etc... I have one view which represents the chart and a view model that is used to define the data item to display (among other things) ...I would basically like to set one of the item mappings at runtime (but obviously I am using MvvM).

This is my series definition

                        <telerik:SeriesMapping>
                            <telerik:SeriesMapping.SeriesDefinition>
                                <telerik:PieSeriesDefinition 
                                    LegendDisplayMode="DataPointLabel"
                                    ShowItemLabels="False" 
                                    ShowItemToolTips="True">
                                    <telerik:PieSeriesDefinition.Appearance>
                                        <telerik:SeriesAppearanceSettings ></telerik:SeriesAppearanceSettings>
                                    </telerik:PieSeriesDefinition.Appearance>
                                </telerik:PieSeriesDefinition>
                            </telerik:SeriesMapping.SeriesDefinition>
                            <telerik:ItemMapping DataPointMember="YValue" FieldName="Commission" />
                            <telerik:ItemMapping DataPointMember="LegendLabel" FieldName="Symbol" />
                        </telerik:SeriesMapping>

and I was hoping to be able to do this (where the DataFieldName would be set in the view model depending on what that particular view instance should show

<telerik:ItemMapping DataPointMember="YValue" FieldName="{Binding ElementName=radChart1, Path=DataContext.DataFieldName}" />

I get an error in Visual Studio, something about a null value. I have tried a number of options for the binding but it doesn't seem to work so maybe it's not possible

My question is should I be able to do this and if not do you have any suggestions on how to achieve what I am trying to do.

Thanks in advance

Can't find ViewModel for RadWindow using Caliburn.Micro

I'm trying to open a RadWindow in my Caliburn.Micro project, but I'm having trouble tying the dialog's View to the ViewModel.

In my ViewModel I open the dialog using:

var radWindowViewModel = new MyViewModel();

var radWindow = new RadWindow

{

Width = 400,

Height = 150,

Content = ViewLocator.LocateForModelType(typeof(MyViewModel), null, radWindowViewModel)

};

radWindow.ShowDialog();

The RadWindow is opened, but in it is displayed: "Cannot find view for MyNameSpace.MyViewModel.

Alternatively, when I set RadWindow.Content the following way:

Content = ViewLocator.LocateForModel(radWindowViewModel, null, null)

then I see the correct View, but the View's DataContext is never set.

Does anyone know what I'm doing wrong?

Blurry icons in Ribbon

Do you agree that the icons/buttons in the RadRichText-Ribbon are more blurry then the icons/buttons in other Ribbons?
You also see the difference in the Teleriks WPF-Controls-Example - application.

[Solved] HowTo FullScreen with RibbonWindow

Hi there,

on a regular Window this makes it appear without a border and overlap the taskbar.

WindowStyle = System.Windows.WindowStyle.None;

Topmost = true;

WindowState = System.Windows.WindowState.Maximized;

However RadRibbonWindows don't get impressed.

Even doing

WindowChrome.SetWindowChrome(this, null);

does not help.

Hints anyone?

Thanks Martin

How to trigger filtering after hit Enter

Inside your Telerik DataFilter for WPF Demo, for those integer columns, when I type in some integer in the text box (for example, make "Quantity=12") and press "Enter", the filtering is not triggered. The data in the Grid stays same. I will have to click out of the text box to make the filtering taking effect. For string columns, it doesn't have this problem. As soon as I hit "Enter", it triggers the data filtering. So my question is how to make the integer column behave the same as string column as regarding to trigger the data filtering as soon as I hit "Enter" in the text box?

Thanks!

[Solved] Can striplines be styled to thin lines?

Hi telerik,

We are currently displaying charts with visible striplines. Our users have requested the 'checker board' to be replaced by thin lines instead. Is that possible?

I have read about giving the areas different colors, but it's not quite what I wish to achieve...
