Focus issue - is something stealing my focus?

Hi Telerik,

It's perfectly possible that my issue is due to not understanding the focus topic, but the general WPF examples I find do not seem to work for me with RadDocking.

Goal / What I try to achieve:
- I wish to be able to double-click a row in a RadGridView, which is inside a RadPane.
- When double-clicking, I wish to open another RadPane, potentially one that's already open and focus a specific control (RadMaskedTextBox) inside the new RadPane.

(Our inspiration is the Error List in Visual Studio - our goal is exactly the same, directing the user to be able to edit a specific, problematic value).

Problem:
The control is not focused, rather the initial window is focused.

What I do:
I use Keyboard.Focus() to focus the RadPane
I use Keyboard.Focus() to focus the specific control.
It's done after the control is loaded and the specific control has .Focusable==.IsVisible==true
Result: System.Windows.Input.Keyboard.FocusedElement shows the desired control.
So far so good!
In the eventhandler OnRowActivated I set e.Handled = true

But when I exit the eventhandler OnRowActivated (that is: after debugging, the app is running again), the Error window has focus, not the one I just gave focus to.

So do my Telerik controls 'draw back' the focus as part of wrapping up the OnRowActivated event handler, or do you have some ideas on what to try out?

Thanks,

Anders, Denmark

Refresh RadGridview in Wpf

I'm developing MVVM application. I bind the DataGrid ItemsSource to a ObservableCollection in the ViewModel code. Every user control (eg. TextBox, Label, etc) in the UI except the DataGrid works fine. When the PropertyChanged event is fired, the value is displayed correctly. But not in the DataGrid, I use TwoWay mode, but it seems that the DataGrid never refresh itself. The DataGrid content is refreshed only when I try to sort any DataGrid column.

Horizontal Bar Chart with high and low-point (like Candle-Stick)

I've got two questions.

1. Is it possible to have a horizontal bar-chart which has a high and low-point (like a candle-stick-chart) ?

2. If yes is it possible to make these bars draggable with mouse or touch-events?

RadGridView, ObservableCollection and currentitem

Hi
I'm trying to replace my wpf listview with radgridview, but the selecteditem binding to the observablecollection does not work.

<ListView Name="lboRoles" Grid.Row="1" Grid.Column="0" ItemsSource="{Binding}" Grid.ColumnSpan="1" IsSynchronizedWithCurrentItem="True" SelectionMode="Single" >

<ListView.View>

<GridView>

<GridViewColumn Header="Name" Width="200" DisplayMemberBinding="{Binding Path=Name}"/>

<GridViewColumn Header="Description" Width="200" DisplayMemberBinding="{Binding Path=Description}"/>

</GridView>

</ListView.View>

</ListView>

<mytelerik:RadGridView x:Name="gvRoles" ItemsSource="{Binding}" SelectionMode="Single" IsReadOnly="True"

Grid.Column="0" Grid.Row="0" IsSynchronizedWithCurrentItem="True" AutoGenerateColumns="False"

ShowGroupPanel="False" CanUserFreezeColumns="False" ShowColumnFooters="False">

<mytelerik:RadGridView.Columns>

<mytelerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Name}">

</mytelerik:GridViewDataColumn>

<mytelerik:GridViewDataColumn Header="Description" DataMemberBinding="{Binding Description}">

</mytelerik:GridViewDataColumn>

</mytelerik:RadGridView.Columns>

</mytelerik:RadGridView>

When selecting a row in the listview, the observablecollection currentrow is changed, but not when selecting a row in the radgridview.
Is there a different way to do this with radgridview? Do I need a binding to selecteditem?

RowIsExpandedChanged and CollapseHierarchyItem

Hi,

I am trying to have a single expand Hierarchy in my GridView, in the RowIsExpandedChanged events i am checking if the row is expanded and i am collapsing the other rows with the CollapseHierarchyItem.

What is happening is that the RowIsExpandedChanged event is raised again when calling CollapseHierarchyItem, how to collapse rows without firing the RowIsExpandedChanged events.

Thanks.
