Marked zone

Hi,
I would like to know how can I add programmatically (in WPF) a marked zone with a transparent infill and colored borders?
Whenever I set the Telerik.Windows.Controls.Charting.MarkedZone Background property to transparent and the BorderBush to blue (or any other colour) nothing is displayed. I would like the chart to look like the one in the attachment.

Cheers

Binding Issue (v2010.3.1314.40)

Hi,

I'm having an issue binding with the RadDatePicker. I'm using WPF, .NET 4.0 and RadControls for WPF Q3 2010 SP1. I'm trying to bind to a property on a view model that implements INotifyPropertyChanged, but it never seems to update the source.

On the xaml:

<telerik:RadDatePicker HorizontalAlignment="Left"

Margin="28,90,0,0"

Name="radDatePicker1"

VerticalAlignment="Top"

Width="223"

SelectedValue="{Binding Path=BoundDate}" />

On the view model:

/// <summary>

/// Gets the BoundDate property.

/// Changes to that property's value raise the PropertyChanged event.

/// This property's value is broadcasted by the Messenger's default instance when it changes.

/// </summary>

public DateTime BoundDate

{

get

{

return _boundDate;

}

set

{

if (_boundDate == value)

{

return;

}

var oldValue = _boundDate;

_boundDate = value;

// Update bindings and broadcast change using GalaSoft.MvvmLight.Messenging

RaisePropertyChanged(BoundDatePropertyName, oldValue, value, true);

}

Thanks in advance,
Wyatt

Filter a second time

After applying one filter, clearing it, then applying a second filter, The results for the first filter show again.

Steps to recreate Using your demo app and the column filters:
1. Did a contains search for "get_" (See attached image getsearch.png)
2. Cleared the search.
3. Did a contains search for "set_"
4. Results that displayed were the intial "get_" results (notice results for setsearch.png are the same as getsearch.png)

I am having the same issue when adding and clearing FilterDescriptors programmatically on the TreeListView.FilterDescriptors collection.

Filters now display [null] instead of nothing

Hi -
We're upgrading our WPF application from Telerik control version 2010.2.0924 (WPF 3.5) to 2011.3.1116 (WPF 4.0).

The issue we're having is that the column filters now behave differently when there are cells that are empty. In the old version, the grid filter would display a checkbox with nothing next to it. In the new version, the checkbox has [null] or [empty] next to it ([null] for number columns, [empty] for string columns).

Please see the attached files that illustrate the behavior. We need the UI behavior to look as it did before, displaying nothing next to the checkbox.

Can this be fixed with the next service pack?

Thanks,
Sandy
