Styling RadPane

Hello,

I am trying to change the styling of RadPanes. I ultimately want to also change the shape of the tabs, but for now I am just trying to customize the colors of the tabs, text, and border of the pane.

I tried putting a RadDocking with a RadPaneGroup and two RadPanes in Blend. I can see the tabs, but when I click on the RadDocking item in the Objects and Timeline, I only see an option to edit a copy of the Template, not the Style. Using the Object > Edit Style menu only show the Create Empty option enabled.

I would appreciate any help as I won't have any hair left to pull out soon. Thanks.

Possible issue with focusing

There is an window with three combo boxes:

<Window ... >

<StackPanel>

<telerik:RadAutoCompleteBox/>

<telerik:RadAutoCompleteBox

x:Name="_combo"

/>

<telerik:RadAutoCompleteBox/>

</StackPanel>

</Window>

and back code:

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

Loaded += MainWindow_Loaded;

}

void MainWindow_Loaded(object sender, RoutedEventArgs e)

{

_combo.Focus();

//_combo.MoveFocus(new TraversalRequest(FocusNavigationDirection.Next)); //(!)

}

Steps:
1. show window
2. type some text (without tabs)

expected: some text appears in second combo box with name "_combo".
actual: second combo box has focused appearance, but does not accept any input
actual with line (!) uncommented: as expected.

This is strange behavior because, for example, dateTimePicker would work as expected without uncommenting line (!)

RadTreeListView Will Not Persist Settings

I have a RadTreeListView in an MVVM project which I am trying to persist with the IsolatedStorageProvider. The RadRibbon control save and load routines use a mediator pattern with ICommand and command classes.It only partially works. I can save and restore column width settings, but IsExpanded and IsSelected cannot be saved and restored. Also, it will not save and restore columns that are moved. I save the settings, move a column and then load the settings, expecting the column to return to its original position, but some or all of the data in the columns disappear. There may be other properties that can be saved or can't be saved, but I don't know what to test for.

Hi,

there is a bug in implicit expression dark theme for RadPropertyGrid when NestedPropertiesVisibility is set to Visible.

Content template of SelectedField is unreadable, because Foreground and Background are almost the same color (light gray)

Here is simple demonstration:

Just select a field in propertygrid and move mouse cursor out of the field

Restrict Image Type

I'm trying to use the Image Editor (WPF Q3 2012 WPF4.0) for the first time. In the open and save dialog is there a way to restrict the user to just JPG files (*.jpg, *.fpeg) types. I don't see how to do this from the documentation.

Multiple textboxes/textblocks in a cell, chooses right one on edit.

I have a GridViewDataColumn with a CellTemplate that contains an ItemsControl which is templated for TextBlocks. The CellEditTemplate has a similar setup only with TextBoxes. Essentially I have several TextBlocks/TextBoxes per cell. What I want is when the user double clicks on a TextBlock the grid goes into editing mode and selects the corresponding TextBox by index. If I double click the third TextBlock in the cell then I want the third TextBox to start editing.

The default behavior is the grid selects the first TextBox upon entering edit mode. I have tried a couple of code behind solutions based on moving through the visual tree when PreviewMouseDoubleClick happens. But when I force the grid to enter edit mode the TextBoxes are not part of the visual tree as I would expect them to be.

I would prefer a pure XAML solution but do not know how that would be done.
