Hi All,
what purpose for Appointment.Location?

Tanks.

IHi,

I have a grouping action event (see below) that fires when as a user I drop a column into the grouping area.  I also get the action event when I close the group.  However, when I create the group descriptor pro-grammatically (see below) the action event does not fire but the group   displays properly.  When I close the  group pro-grammatically created group I get the action event but  the program crashes.  What am i missing?

        private void CreateGroup_Click(object sender, RoutedEventArgs e)
        {
            GroupDescriptor descriptor = new GroupDescriptor();
            descriptor.Member = "CategoryName";
            descriptor.SortDirection = ListSortDirection.Ascending;
            this.gridQueryResult.GroupDescriptors.Add(descriptor);
           
            descriptor = new GroupDescriptor();
            descriptor.Member = "ProductName";
            descriptor.SortDirection = ListSortDirection.Ascending;
            this.gridQueryResult.GroupDescriptors.Add(descriptor);           
        }

private void gridQueryResult_Grouping(object sender, GridViewGroupingEventArgs e)
        {
            Telerik.Windows.Controls.GridViewColumn column = ((ColumnGroupDescriptor)e.GroupDescriptor).Column;

            if (e.Action == GroupingEventAction.Place)
            {
                if (column != null)
                    column.IsVisible = false;
            }
            else if (e.Action == GroupingEventAction.Remove)
            {
                if (column != null)
                    column.IsVisible = true;
            }
        }

Hello,
I have set the SelectionMode="Extended" on my RadListBox; however the behavior identical to "Multiple", whereas Shift and Ctrl have no effect.  Below is my Xaml...


Is this a known bug or am I missing something?

Thanks in advance,
Steve

I have the following XML generated by the SaveLayout method:


When I execute the LoadLayout method with this XML, I receive this exception:

Specified argument was out of the range of valid values.
Parameter name: elementTypeName

Any help would be appreciated - thanks.

Hi, 

Does the Timeline control support multi-grouping, for instance I havea Group 1 when expanded it displays child groups and when child groups are expanded the related events are then displayed.

Thanks

Nevermind, I found this

Hi,

I have a RadDataFilter whose Source property is bound to ObservableCollection and AutoGenerateItemPropertyDefinitions is set to false:

            <telerik:RadDataFilter Name="radDataFilterSessions" Margin="-15,0,0,0"
                               MaxWidth="600" AutoGenerateItemPropertyDefinitions="False"
                               Source="{Binding DomainContext.Sessions}">
            </telerik:RadDataFilter>
            
Properties to filter are manually defined:
            
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Name", typeof(string), "Name"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Description", typeof(string), "Description"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Recorded", typeof(DateTime), "Recorded"));
            radDataFilterSessions.ItemPropertyDefinitions.Add(new ItemPropertyDefinition("Duration", typeof(TimeSpan), "Duration"));
            
There seems to be problem with Duration (TimeSpan) property. I can add filter item with this property. I can change value and filter, but when I try to remove this filter item (remove a filter by using RadDataFilter's UI remove button), I got NullReferenceException:

at Telerik.Windows.Controls.Data.DataFilter.FilterEditorFactory.TimeSpanEditorConverter.Convert(Object value, Type targetType, Object parameter, CultureInfo culture) in c:\TB\117\WPF_Scrum\Release_WPF\Sources\Development\Controls\Data\DataFilter\Editors\FilterEditorFactory.cs:line 256

No problems with String and DateTime properties. I am using 2013.2.611.45 build.

I  have builder a  RadControlsWPF Application with  implicit style 
No matter when running, or design，can't show Window as a main  RadWindow,How can i solve this problem

thanks !

I have a RadGridView and in this RadGridView I have the following column:



I want to either enable/disable or set the read only flag on another two columns in the grid based on the checkbox column.

 

So far I have tried binding the `IsReadOnly` and `IsEnabled` property to `Revoked` but this doesn't seem to work, and I can see that the `Revoked` property is being set and the `RaisePropertyChanged` event is recurring.

Any help would be much appreciated.

Further details of the code in the ViewModel




And the NotificationAgreement class has the following property.
