[Solved] How to format a string in RadRibbonBackstageItem?

I am trying to format the header string that is bound to an item from the view model.

eg

Header="{Binding EstimateTakeoffService.SelectedEstimate.Title, StringFormat='Estimate Information: {0}'}"

This doesn't show the "Estimate Information:"

Why does this not work?

Many thanks

CustomAppointment changes not reflected after closing custom EditAppointmentDialogWindow

I created a custom Appointment (ScheduledItem) and a custom EditAppointmentDialogWindow style with a ViewModel.When running the application my properties are filled in, but when I hit the OK button, the changes are not reflected in the ScheduleView.
It also seems that the BeginEdit, CancelEdit and EndEdit methods of the custom ScheduledItem are not called. I supposed I have to call them from my DialogViewModel?But what do I have to do to confirm the changes in the custom appointment object, so they will be reflected in the ScheduleView?

Set property isSelected for cell

I am using Telerik version 2014.1.331.45

I have a RadGridView like:

<telerik:RadGridView Name="RadGridView" ItemsSource="{Binding DynamicValues, Mode=TwoWay}"

<br>                             SelectedItem="{Binding SelectedItem, Mode=OneWayToSource}" CanUserDeleteRows="True" <

br

>                             CanUserInsertRows="True" CanUserReorderColumns="False" CanUserSortColumns="False" <

br> ShowGroupPanel="False" IsFilteringAllowed="False" SelectionMode="Extended" SelectionUnit="Mixed" IsSynchronizedWithCurrentItem="True" <br

>                             behavoirs:ValidationBehavior.IsValidationEnabled="True" ClipboardPasteMode="SkipHiddenColumns">

I need to select all cells of column on clicked column header

i wrote next code for make header clickable:

foreach (var column in RadGridView.Columns) { var temp = column.Header; column.Header = new MyButton { Content = temp.ToString(), ViewModel = this }; }

and custom button class:

private class MyButton :RadButton { public override string ToString() { return Content.ToString(); } protected override void OnMouseDown(MouseButtonEventArgs e) { if (ViewModel.columnHeaders.ContainsKey(e.Source.ToString())) { foreach (var value in ViewModel.RadGridView.Items) {<br

>                        var row = ViewModel.RadGridView.ItemContainerGenerator.ContainerFromItem(value) as GridViewRow;<

br> if (row != null) row.Cells[index].IsSelected ??? } } base.OnMouseDown(e); } public EditViewModelBase ViewModel { get; set; } }

but row.Cells[index] does not have property IsSelected, how I can set cell property selected?

ActiveTool=MouseTool.ConnectorTool Does not work for MVVM

Hi,

I apply mvvm pattern for RadDiagram. Both shapes and connections are bound to classes that derive from the Diagram.Extension classes. Everything works quite fine except, I cannot add new connection using the ActiveTool=MouseTool.ConnectorTool. When I set the ActiveTool to Connector tool, the mouse cursor changes to connector mode but it does not draw any arrow when clicked and moved on the Diagram. How can I provide the functionality to add connections between the shapes and keep the MVVM pattern?

Thanks in advance,
Semih

Can't Paste more than once into RadTextInputBox

Hi,
We've just upgraded to Q2 2014 and replaced retired RadMaskedTextBox with RadMaskedTextInput with these properties set
<Setter Property="Mask" Value="###-###-####" />
<Setter Property="EmptyContent" Value="___-___-____" />
<Setter Property="IsClearButtonVisible" Value="False" />
<Setter Property="AllowInvalidValues" Value="False"></Setter>

Two issues:
1. Mask is set to ###-###-####. However, it allows for spaces.
2. I can't paste more than once into it. First Paste works fine, but then if I delete the contents and paste again with Context Menu Paste, nothing happens. If I use Ctrl+V, it does paste but only after second try.

Is there a way to fix both?

RadToolBar not working after upgrade

I just upgraded to the latest WPF controls. Now the tool bar is acting funky. I have a grid within the toolbar that has various labels and text boxes. It displayed fine before the upgrade. Now the tool bar displays a black tool bar but by clicking on the arrow on the far right side of the control the correct tool bar pops up above the tool bar.

I've played around with the band and band index settings but nothing works.

Any help would be greatly appreciated.
