How to style the RadListPicker control / Expression Blend 2012

[Alex]

Hello,

I would like to change the default style of the RadListPicker instance in my page, especially the style of the full screen pop-up.

For that i'm trying to use Expression Blend 2012 like described here : http://www.telerik.com/help/windows-phone/radlistpicker-styles-and-templates-styling-radlistpicker.html

1. "In the 'Objects and Timeline' pane, select the RadListPicker control you want to style. From the menu choose Object -> Edit Style -> Edit a Copy. You will be prompted for the name of the style and where to be placed."

=> I don't have the "Edit style" menu item when I right-click on the RadListPicker (However I have this option for a Grid control, for instance).

2. "If you haven't generated the default style yet, you can choose Edit Template -> Edit a Copy. It will generate both the style and the template."

=> When I click on "Edit Template / Edit a copy" then nothing occurs. It works if I use the same steps on a RadTimePicker instead of a RadListPicker (a window is opened to name the template/style to generate).

Could you help me ? How can I use Expression Blend correctly ? Eventually could you provide me the XAML fragment I need ?

Thanks,

Alex.

Hi Jean-Alexis Aufauvre,

Here is a copy of the Control Template of RadListPicker:

Thank you. I added the style you gave in the application resources of the app, but when I set the Style attribute of the RadListPicker control I get the following exception :

[MS.Internal.WrappedException] = {MS.Internal.WrappedException: Error HRESULT E_FAIL has been returned from a call to a COM component. ---> System.Exception: Error HRESULT E_FAIL has been returned from a call to a COM component.
   at MS.Internal.XcpImports.CheckHResult(UInt32 hr)

=> Is it possible to debug that ?

The solution I found (which should work for me) is to only change the style of the popup adding the PopupStyle and PopupHeaderStyle attributes to the RadListPicker control.

But I have one last issue: I don't know how to change the header background of the popup (it's always gray, even when setting the background property) :

<Style x:Key="PopupHeaderStyle1" TargetType="ContentControl">
        <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeExtraLarge}"/>
        <Setter Property="Background" Value="{StaticResource PhoneBackgroundBrush}"/>
        <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiBold}"/>
        <Setter Property="Margin" Value="24,55,0,35"/>
        <Setter Property="HorizontalContentAlignment" Value="Left"/>
    </Style>

    <Style x:Key="PopupStyle1" TargetType="telerikPrimitives:RadDataBoundListBox">
        <Setter Property="FontSize" Value="{StaticResource PhoneFontSizeExtraLarge}"/>
        <Setter Property="FontFamily" Value="{StaticResource PhoneFontFamilySemiLight}"/>
        <Setter Property="Background" Value="{StaticResource PhoneBackgroundBrush}"/>
        <Setter Property="HorizontalAlignment" Value="Stretch"/>
        <Setter Property="VerticalAlignment" Value="Stretch"/>
        <Setter Property="CheckBoxStyle">
            <Setter.Value>
                <Style TargetType="telerikPrimitives:ItemCheckBox">
                    <Setter Property="VerticalAlignment" Value="Center"/>
                    <Setter Property="Margin" Value="0, 0, -18, 0"/>
                </Style>
            </Setter.Value>
        </Setter>
    </Style>

Thanks again for your help,

Alex.

I just saw that the popup header background is forced to gray (Background="{StaticResource PhoneChromeBrush}") in the template, so it cannot be changed in a Setter of the PopupHeaderStyle.

I manage to use and modify the template you gave in the first place, so my problem is solved :)

Thanks.
