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,

ChartView

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.

Dismissing the MinimizedPopup

Hi,

When the RadRibbonView.IsMinimized is set to true the ribbon is minimized. Clicking on a tab opens a popup to display the group and items. Is there a way to dismiss the popup when a user clicks on an item in the tab, similar to the behavior in Microsoft's ribbon? Currently, only when the user clicks outside of the tab, the popup will go away and return to the minimized ribbon state. I found the RadRibbonView.IsMinimizedPopupOpen, but this property cannot be set. Any ideas?

Thanks,
Trang

RadRibbonSplitButton - MVVM

I played with the sample for the RadRibbon in MVVM.
There is an example of DataTemplate for the RadRibbonSplitButton.
However, the sample is not complete and does not show how to bind "Contextual" items of the RadRibbonSplitButton.

I tried this

<DataTemplate x:Key="MenuItemTemplate">

<TextBlock Text="{Binding Text}" />

</DataTemplate>

<DataTemplate x:Key="SplitButtonTemplate">

<telerik:RadRibbonSplitButton

Text="{Binding Text}"

Size="{Binding Size}"

SmallImage="{Binding SmallImage}"

LargeImage="{Binding LargeImage}">

<telerik:RadRibbonSplitButton.DropDownContent>

<telerik:RadContextMenu

ItemTemplate="{StaticResource MenuItemTemplate}"
