Hey, I'm using Visual Studio 2012 and have a C# based WPF project. I've imported the telerik controls into my toolbox and it looks like they're all there except for the RadComboBox. I can access the RadComboBox library in the code, just can't see it in my toolbox to place in forms. I've tried switching the version number of my project, but it still doesn't show up. Is there something I need to do to import the RadComboBox to the toolbox?

X-Axis label values not populating

Hello, I'm creating a bar chart. My AxisY is a integer count and my AxisX is a string for a build number.

My ItemSource is pointing to an

ObservableCollection<Tuple<string, int>>

If I have 30 build buckets, when viewing my chart the buckets for my AxisX are numbered 1-30, instead of the string buildnumber. How can I get my buildnumber to show up as the tick name instead of this 1-30?

Thanks, Josh

Image Example

<telerik:RadChart x:Name="radChart" ItemsSource="{Binding DataPoints}"

Visibility="{Binding ServiceState,

Converter={StaticResource EnumToVisibilityConverter},

ConverterParameter=ServiceOk}">

<telerik:RadChart.DefaultView>

<telerik:ChartDefaultView>

<telerik:ChartDefaultView.ChartArea>

<telerik:ChartArea>

<telerik:ChartArea.AxisX>

<telerik:AxisX IsDateTime="False"

LayoutMode="Auto"

Title="Build"

LabelRotationAngle="55"

Visibility="Visible"/>

</telerik:ChartArea.AxisX>

<telerik:ChartArea.AxisY>

<telerik:AxisY Title="Unique Crashes"

Visibility="Visible" />

</telerik:ChartArea.AxisY>

</telerik:ChartArea>

</telerik:ChartDefaultView.ChartArea>

</telerik:ChartDefaultView>

</telerik:RadChart.DefaultView>

Automatic sorting event when cell is edited

Hi,

I'm struggling on a sorting problem. I have 2 gridviews that are bound to the same list. Only one of the gridviews is editable. The other one is for reporting purposes only and so readonly.

Because they represent the same data, the filtering and sorting must be syncronized. For the sorting part, I've added a 'Sorting' event on grid n°1. In the event handler I copy the sorting descriptors into the second grid. This works fine.

private void GridViewSorted(object sender, GridViewSortedEventArgs e)

{

var datagrid = sender as RadGridView;

if (datagrid == null || !datagrid.Equals(EmployeeGrid)) return;

FormationGrid.SortDescriptors.Replace(datagrid.SortDescriptors);

}

When I edit a cell of one of the sorted columns in grid n°1, the grid is automatically sorted according to the existing sorting of that column. This is desired off course.
However, the event 'GridViewSorted' isn't called and thus my second grid doesn't sort, which makes that my grids aren't sorted equally anymore.

Does anybody have some advice on how to make sure my both grids are synchronized after a cell edit?
I've tried following already, but sorting on the 2nd grid just kicks in, when you enter and leave the same cell again after you've edited it.

private void EndCellEdit(object sender, GridViewCellEditEndedEventArgs gridViewCellEditEndedEventArgs)

{

var datagrid = sender as RadGridView;

if (datagrid == null || !datagrid.Equals(EmployeeGrid)) return;

FormationGrid.SortDescriptors.Replace(datagrid.SortDescriptors);

}

ScrollTimeRuler Doesn't work in a MVVM Scenario

Hello,
WPF controls version: 2012.2.0912.40

I'm attempting to create one (1) scheduleview for multiple employees. (We're using the Day and Week View Definitions only). The goal is to be able to view different "Work Schedules" of several employees. So if I check the employee's name, the scheduleview should only display that employee's work schedule (i.e,. 8am to 5pm, or 9am to 6pm, etc). I can do this fine in code behind using the ScrollTimeRuler(just as a sample), but we are using MVVM and I do not see a way to call ScrollTimeRuler from my ViewModel.

Is this possible? and/or do you have any suggestions or samples?

Thanks,
Brian Foster

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.

Hello,

I have a problem with WPF Command and I need some Help.
I defined some static RoutedCommand in my App class. My main window is composed of a RadRibbonView and a RadTabControl.
I Populate the TabControl with some classes that inherit from RadTabItem.
Buttons in the ribbon are bound to my RoutedCommand and I add commandbindings bound to the commands In my RadTabItem children classes.
My TabItem has the Content property set to a UserControl.The buttons works fine while the TabItem header has the focus but if I click on the content of the TabItem (my UC), the button stop calling the CanExecute and Executed callbacks of my TabItem.
I Want the selected TabItem always manage the CanExecute and Execute call for all commands.

How can i handle this ?

Thank you,
