Hi,

How can I apply any of built in application theme (for example Windows7) to my application to see it on design time for example in blend.

Now I am using this:

StyleManager.ApplicationTheme = new Windows7Theme();

And it is working on run time but of course not in designer.

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}"

ItemsSource="{Binding SplitSubButtons}" VerticalAlignment="Top">

<telerik:RadContextMenu.ItemContainerStyle>

<Style TargetType="telerik:RadMenuItem">

<Setter Property="Icon">

<Setter.Value>

<Image Source="{Binding Path=SmallImage}"/>

</Setter.Value>

</Setter>

</Style>

</telerik:RadContextMenu.ItemContainerStyle>

</telerik:RadContextMenu>

</telerik:RadRibbonSplitButton.DropDownContent>

</telerik:RadRibbonSplitButton>

</DataTemplate>

As soon as I have more that one item, only the last icon is shown.

Any advice?

Regards,

Nic

Pin point alignment / Gauge skinning

Hello,

I'm trying to make my gauge resmeble something like this: http://i48.tinypic.com/20qf5d.jpg but I'm having a couple of issues.

- How can I center the pin point and hold a textblock / label within it?
- How to add custom labels (e.g. just have 0 Min / 1 Hour)
- As you can see in my code below I have a bar indicator but for some reason it dosen't show up

Here is my code so far:

<telerik:RadRadialGauge Width="420" Height="300" telerik:StyleManager.Theme="Metro">

<telerik:RadialScale Min="0" Max="60" LabelRotationMode="None" LabelOffset="0.1" RangeLocation="Outside" MajorTickLocation="OverCenter"

MajorTickBackground="#FFE7F1F6" MinorTickBackground="#FFE7F1F6" MiddleTickBackground="#FFE7F1F6" MajorTickStep="10" LabelLocation="Outside" Fill="#FFE7F1F6">

<telerik:RadialScale.Indicators>

<telerik:BarIndicator x:Name="radialBar" Value="30" Background="#66bc29"

telerik:ScaleObject.Location="Outside" telerik:ScaleObject.Offset="0.5" />

<telerik:Pinpoint Background="#79a9c0" BorderBrush="#FFF7F9FB"

MinWidth="125" MinHeight="125" HorizontalContentAlignment="Center"

VerticalContentAlignment="Center" StrokeThickness="5" Margin="0" Padding="0" />

</telerik:RadialScale.Indicators>

</telerik:RadialScale>

</telerik:RadRadialGauge>

And here is how it looks so far: http://i45.tinypic.com/2po7cj6.jpg

It's getting there slowly so would appreciate some help on my questions above!

Group Sorting in gridview

Hi,

I have Gridview that is abound to a collection of object “Benefit”, which has an Amount (decimal) that I would like to group on it is value. I have ranges with a text value that returns the corresponding range for that amount

Less than 100
100 – 250
250 – 500
Greater than 500

When I apply a group descriptor, the grouping occurs on these text vales, but it is sorted alphabetically. How can control the sorting of the group itself? I can convert that Range property to return integer value, but I still want to display the group text as above. I tried the Generic Group Descriptor <TElement, TKey, TSortKey> but didn’t help.

How can resolve this?

Cheers

Image for checkable RadMenuItem

I'm using context menu with checkable items. In order to meet UI design requirements I need to use custom icons for checked items instead of check mark. Please look at attached screen shot.

Current behavior:

- If item is checked then default check mark is displayed and it can't be changed.
- If item is not checked Icon image is displayed.

Expected behavior:

- If item is checked custom image is used instead of check mark (or some frame is drawn around icon - see green arrow).
- If item is not checked then defalt icon is displayed.

Looking forward for your response.
