Any idea?

Adding New Pane to a Saved Layout

I have a situation where I have added a new pane to the docking control, since the software has been released. Anyone who has used the software before I added this new pane has a file with the saved layout information. When the software is loaded, it uses the layout file to format the dock panel.

I'm having an issue allowing the user to display the new pane that I added. Since it was created after the layout file was saved, it's data is not included within it. How do I add new panes to the dock after an "out of date" layout file is loaded?

Reorder with drag&drop does not work anymore

Hi,

with release Q2 2011 it is not possible to reorder the columns of a RadGridView with drag&drop. The drop adorner is not shown.
With release Q3 2010 this works perfectly. Are there any modifications I have to make in my code?

Best regards

Uli

RadGridView grouping issues

We recently "upgraded" to WPF 3.5 Q1 2011. We have a RadGridView with grouping that cuts off the last detail row in each group. In most cases only a few pixels of the last row in each group are visible. This used to work in previous release and latest hotfixes did not help.

Here is our XAML:

<tel:RadGridView x:Name="ListsGV" Grid.Row="2" ItemsSource="{Binding EditFormViewModelCollection}"

IsReadOnly="True" SelectedItem="{Binding CurrentEditFormViewModel}"

PreviewMouseDoubleClick="gridView_PreviewMouseDoubleClick"

HeaderRowStyle="{StaticResource HeaderStyle}"

CanUserSortColumns="False">

<prism:CommandBehaviorCollection.Behaviors>

<prism:BehaviorBinding Event="MouseDoubleClick" Command="{Binding TableSelectedDoubleClickCommand}" CommandParameter="{Binding ElementName=ListsGV, Path=CurrentItem}" />

</prism:CommandBehaviorCollection.Behaviors>

<tel:RadGridView.GroupDescriptors>

<tel:GroupDescriptor Member="CurrentList.SystemModule" />

</tel:RadGridView.GroupDescriptors>

<tel:RadGridView.GroupHeaderTemplate>

<DataTemplate>

<TextBlock Text="{Binding Header.Description}" Margin="1,0,0,0" />

</DataTemplate>

</tel:RadGridView.GroupHeaderTemplate>

<tel:RadGridView.Columns>

<tel:GridViewDataColumn Header="Description" DataMemberBinding="{Binding CurrentList.Description}"

HeaderCellStyle="{StaticResource HeaderCell}" MinWidth="300" />

<tel:GridViewDataColumn Header="Shared Operations" DataMemberBinding="{Binding CurrentList.SharedOperation}"

HeaderCellStyle="{StaticResource HeaderCell}" Width="*"/>

</tel:RadGridView.Columns>

</tel:RadGridView>

Resource Grouping and Scrolling

Hi there,

Question 1) Is it possible for the ScheduleView to group resources as the following?

Rooms
   - Room 101
   - Room 102
   - ...
   - Room 106
----------------------------------
Reservations
   - Reservation Z8329
   - Reservation Z8342
   - ...
   - ...
   - Reservation Z8451

Question 2) Is it possible to have different vertical scroll bar for different resource type BUT share the same horizontal scroll?

Please review the screenshot for more detailed drawing.

Crash when closing RadPane created from Binding

Hi,
I have a problem with RadPaneGroup. I want to create RadPanes dynamically via a binding on ItemsSource of RadPaneGroup. The list for the binding is a ObservableCollection<RadPane>. Everything works as expected until it want to close these RadPanes and click on the "x"-button. The program crashes instantly with the following exception:
"Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead."

We use version 2011.1.315.35 of the Telerik components.

Viewmodel base:

public class ViewModelBase : INotifyPropertyChanged

{

public String DisplayName { get; set; }

protected void RaisePropertyChanged(string propertyName)

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

}

public event PropertyChangedEventHandler PropertyChanged;

}

Viewmodel:

public class TestViewModel : Model.ViewModelBase

{

private ObservableCollection<RadPane> m_PaneList = new ObservableCollection<RadPane>();

public ObservableCollection<RadPane> PaneList

{

get { return m_PaneList; }

set

{

m_PaneList = value;

RaisePropertyChanged("PaneList");

}

Docking definition in XAML:

<telerik:RadDocking Grid.Row="1" HasDocumentHost="True" HorizontalAlignment="Stretch" Name="radDocking1" VerticalAlignment="Stretch">

<telerik:RadSplitContainer>

<telerik:RadPaneGroup Name="radPaneGroup1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" ItemsSource="{Binding Path=PaneList}">

</telerik:RadPaneGroup>

</telerik:RadSplitContainer>

</telerik:RadDocking>

Creation of the RadPanes:

TestViewModel testViewModel = this.DataContext as TestViewModel;

RadPane pane = new RadPane {Header = "Test"};

if (testViewModel != null)

{

testViewModel.PaneList.Add(pane);

}

Am I doing anything wrong here?

RadDataForm basic layout

I am finding that the content of the RadDataForm control (using the Metro theme) is small. When I say "the content" I mean the fields within the RadDataForm control.

When the basic layout is used, all controls are the same size. If I add for example FontSize="16" to the RadDataForm control, I get different sizes in the rendered controls. For example:

* The DateTime field is 6 pixels taller than the ComboBox
* The regular TextBox field is 3 pixels taller than the ComboBox

Also, the RadDataForm header seems to get bolded when the font size is increased. Finally, is there a way to establish the space between the labels (on the left) and the controls (on the right)?

Thanks in advance, Marcelo.

GridViewComboBoxColumn DropDown Event

Hello,

I need to be able to update a GridViewComboBoxColumn's ItemsSource when it drops down. How can I capture the drop down event of the GridViewComboBoxColumn? An example would be appreciated.
