Split bar disappears when docking

In my wpf application I noticed that while using RadDocking users can drag windows into a layout so that the split bar between adjacent sections is no longer present. This is very annoying to the users.

This can easily be reproduced using the silverlight demo and probably the wpf one also.

In the "Split Containers" demo, drag pane "Pane Bottom 2" to the bottom half of "Pane Right 2". You will notice that before this "Pane Right 1" and "Pane Right 2" had a split bar between them. After they do not. This happens with other combinations also.

GridViewCheckBoxColumn not saving state after being checked

I am having trouble getting a bound boolean to a GridViewCheckBoxColumn to show its state.

<telerik:RadGridView Name="dgvBreaks" ShowGroupPanel="False" Margin="0,0,0,53" AutoGenerateColumns="False" SelectionUnit="Cell">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Price}" Header="Price" Width="120" IsReadOnly="True" />

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding MatchUs}" Header="Match Us" AutoSelectOnEdit="True" EditTriggers="CellClick" />

<telerik:GridViewCheckBoxColumn DataMemberBinding="{Binding MatchThem}" Header="Match Them" AutoSelectOnEdit="True" EditTriggers="CellClick" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

It looks like everything is binding fine, but if I click on the checkbox and go to another cell, the state of the checkbox is reset. I bound a normal GridViewDataColumn to the boolean field and I can see that the value is updated each time I click on the cell.

I am using build version 2012.1.326.40

Styling Chartview

Hi there,

How would you style the slices on a PieChart programatically?

assume this code...

Dim radPieChart1 As New RadPieChart()

Dim series As New PieSeries()

series.DataPoints.Add(New PieDataPoint() With {.Value = 100})

series.DataPoints.Add(New PieDataPoint() With {.Value = 35})

series.DataPoints.Add(New PieDataPoint() With {.Value = 15, .OffsetFromCenter = 0.3, .IsSelected = True})

radPieChart1.Series.Add(series)

LayoutQ4.Children.Add(radPieChart1)

I would like to have say... slice 1 blue, slice 2 yellow, slice 3 red...

Thanks and best regards,

Optimized Adds don't work?

Hi,

I have a RadTreeListView (version 2011.2.712.35) whose ItemsSource is a custom implementation of INotifyCollectionChanged. The custom version is intended to be more efficient than ObservableCollection by bundling multiple sequential Adds or Removes into a single NotifyCollectionChanged event. The single event has a list of NewItems or OldItems with more than one item in it.

The RadTreeListView seems unable to handle this event correctly. In response to an Add event with two items, it only updates the display with the first of the items. In response to an Add event with 5 items, only the first two appear in the display.

Is this a known problem? Has it been fixed in a later version than the one I have?

Thanks,
Bob

Disable ListBox Items

I've got a listBox initialised with the following:

lbxFunction.ItemsSource = Enum.GetValues(typeof(ChartAggregateFunction));

How do I disable certain ListBox items?

I tried:

((RadListBoxItem)lbxFunction.Items[0]).IsEnabled = false;

I get an error.

Any solutions will be appreciated.
