Header Text dissapears when Style changes in code

Hello, I have a RadTileView where I want to change the header background color when the tile gets minimized.
When I apply the new style the header text disappears, this doesn't happen when the new style is the same as the old one

(I know this example only works when all items are minimized, not when you maximize another item, but this is just for test purposes)

C#:

private void RadTileViewItem_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)

{

RadTileViewItem item = (sender as RadTileViewItem);

if (item.TileState == TileViewItemState.Maximized)

{

item.TileState = TileViewItemState.Minimized;

item.HeaderStyle = (Style)FindResource("TileViewItemHeaderStyle4");

}

else

{

item.TileState = TileViewItemState.Maximized;

}

XAML:

<UserControl xmlns:my="clr-namespace:WpfApplication1" x:Class="WpfApplication1.NodeView"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

<Setter Property="Background" Value="Blue">

</Style>

</UserControl.Resources>

<Grid>

<telerik:RadTileView Name="radTileView1" MinimizedColumnWidth="300" MinimizedRowHeight="155" VerticalAlignment="Top" IsVirtualizing="True" Grid.ColumnSpan="3">

<telerik:RadTileViewItem Header="Node Back Left" HeaderStyle="{StaticResource TileViewItemHeaderStyle1}" MouseLeftButtonUp="RadTileViewItem_MouseLeftButtonUp"/>

</telerik:RadTileViewItem>

</telerik:RadTileView>

IOException was thrown on "RadNumericUpDown"

Using 2012.2.607.40 I receive an exception, "Cannot locate resource 'themes/genericmetrotouch.xaml'", in the VS 2010 Xaml designer when a RadNumericUpDown control is included in the form. I've included a screenshot of the exception. There is no exception when running the app, or if I display the form in Blend.
Thanks,
Steve

Floating Rad Pane To Dock

Hi,

I have read an article where the when we use the rad pane to float. It uses FloatingOnly. Is there a way to override this menu to use the method MakeFloatingDockable instead of MakeFloatingOnly

Also how would you re-dock a floating window from code.

Custom theme for RadTimeline

I'm trying to make a custom theme for the RadTimeline.

Im my custom theme, I want to wrap a ScrollViewer around the Timeline's TimelineItemContainer just like described in this post: http://www.telerik.com/community/forums/silverlight/timeline/vertical-scrollbar-scrollviewer-and-radtimeline.aspx
and I want to remove the horizontal scrollbar of the control (the RadSlider at the bottom).

I've tried to create a custom theme using the approach described here:
http://www.telerik.com/help/silverlight/common-styling-apperance-themes-custom-theme-project-telerik-approach.html
(albeit the documentation is for Silverlight, couldn't find anything similar for WPF)
and I've also had a look at the sample project here:
http://www.telerik.com/community/forums/wpf/general-discussions/how-can-i-create-a-custom-theme-for-wpf-application.aspx

I couldn't manage to get the theme working.
I'm not sure if I made everything right in the theme project - especially the following things in the XAML of my custom theme:

<my:MyTheme x:Key="Theme" />
The many references to ThemeType=telerik:Office_BlackTheme
content of Generic.xaml
declaration of MyTheme class

Basically, I've just copied the file C:\Program Files (x86)\Telerik\RadControls for WPF Q1 2012 SP1\Themes\WPF40\Windows7\Themes\Telerik.Windows.Controls.DataVisualization.xaml which contains the style for RadTimeline to my CustomTheme project and modified the style there. I'm not quite sure, if that was correct, or what I've done wrong.

Actually, it doesn't have to be a whole custom theme, I just want to change the style of RadTimeline like described above. So, my first try was to edit the style using Expression Blend. I selected the RadTimeline and chose: Edit Template --> Edit a Copy. This alone shouldn't change the style at all, shouldn't it? But instead, the whole control is white/transparent - please see the attached files before_edit_template.png and after_edit_template.png. I expect it to look exactly the same as before calling Edit Template --> Edit a Copy. Why isn't it?

Here (http://johannes.unterguggenberger.info/TimelineCustomTheme.zip) is a Solution which contains 2 Projects: A custom theme project and a project which uses the custom theme (at least tries to) to change the style of a RadTimeline. Maybe someone could have a look at it and maybe tell me, what's the problem, or point me in a direction.

Thanks in advance!

TabControl's content

Hi,

Is it possible to do these two things with TabControl (TabOrientation="Vertical" and TabStripPlacement="Left")

1) all TabItem headers to occupy all available space. (ex, if tabControl's Height is 500, and we have 5 TabItems, then each TabItem should have Header.Height = 100. I am using below template to make TabItem;'s header wider, but I am setting the Height explicitly.

<DataTemplate x:Key="tabItemTemplate">

<Grid Height="100">

<TextBlock Text="{Binding Mode=OneWay, Converter={StaticResource enumConverter}}" VerticalAlignment="Center"/>

</Grid>

</DataTemplate

>



<telerik:RadTabControl ItemsSource="{Binding Source={x:Static data:ActivityType.Production}, Converter={StaticResource enumWithoutNoneConverter}}"

                       ItemTemplate="{StaticResource tabItemTemplate}"

                       SelectedItem="{Binding SelectedType}"

                       TabOrientation="Vertical"

                       TabStripPlacement="Left" />

2) I would like to set the Content of each TabItem to null (Nothing). Currently it is displaying the same text as Header does, only without converter. I don't want it to display anything, I just need TabControl;s headers visible.

Regards,
Goran

SelectAll

I was hoping to implement SelectAll functionality when the user double clicks in the cell that is to the left of the first column and above the first row.

I tried using hittesting to detect when the user clicks there, but didn't have any luck since it wasn't coming up as a valid row or column.

Is is possible to do this?

BringItemIntoView

Hi,

I'm using RadControls for WPF (version 2012.1.326.40), and my question is about the RadTreeView.
I want to select by code a specific item even if all nodes of the treeview has not been generated.
My treeview is using the virtualization mode, so the items are not generated until the node is expanded.
How can I select an item ? If I explore the nodes, I have only the generated nodes.
And I can't use the BringPathIntoView method, because my nodes have different types so it's impossible for me to use the property TextSearch.TextPath.
Do you have any solutions ?
