We're having some problems upgrading our project to the current release (2011 Q1) from an earlier version.
We are attempting to upgrade from Q2 2010, and we've confirmed that the Q3 2010 seems to work fine.

The issue is with autogenerated GridViewColumns that are to be invisible by business logic (we have some controls
that require additional parameters to be in the bound dataset). The columns seems to ignore the visible-switch or have some
new logic regarding column width calculation, so that the result is a grid with column values overlapping the same space.

Upon resizing the column headers, the cells snaps back to their respective columns, but initially they are overlapping. There
seem also be some extra columns in the header, probably correlating to the hidden columns in our dataset.

PS! I'm using the binaries with version/tag v.2011.1.315.40

Best regards,
Finn

GroupHeaderStyleSelector not working

Hi, I've just installed the 2011 Q1 binaries and have found that my GroupHeaderStyleSelector, although still called, is not being used to style the resource GroupHeaders.

The attached files illustrate the problem:-

presingledayresizeproblem.png - Group Header styling pre-2011 binaries
missinggroupheaderstyling.png - Group Header styling with 2011 Q1 binaries

Please advise what has changed.

Thanks,
Peter.

Why are some things not working?

Hi,

could it be, that there are some "bugs" in Schedule View?

First i tried following:

<radSchedulerView:RadScheduleView FontSize="18" x:Name="_sView" Grid.Column="0" Grid.RowSpan="2">

<radSchedulerView:RadScheduleView.ViewDefinitions>

<radSchedulerView:DayViewDefinition DayStartTime="00:00:00" DayEndTime="23:59:59" MinTimeRulerExtent="1800" />

<radSchedulerView:WeekViewDefinition DayStartTime="00:00:00" DayEndTime="23:59:59" MinTimeRulerExtent="1800"/>

<radSchedulerView:MonthViewDefinition />

<radSchedulerView:TimelineViewDefinition DayStartTime="00:00:00" DayEndTime="23:59:59" MinorTickLength="1day" />

</radSchedulerView:RadScheduleView.ViewDefinitions>

</radSchedulerView:RadScheduleView>

 _sView.AppointmentEditing +=

                    new EventHandler<AppointmentEditingEventArgs>(OnScheduler_AppointmentEditing);

_sView.AppointmentCreating +=

                    new EventHandler<AppointmentCreatingEventArgs>(OnScheduler_AppointmentCreating);







private void OnScheduler_AppointmentCreating(object sender, AppointmentCreatingEventArgs e)

{

e.Cancel = true;

}

private void OnScheduler_AppointmentDeleting(object sender, AppointmentDeletingEventArgs e)

{

e.Cancel = true;

}

Every time I double click an Appoinment in Schedule View, the Edit Dialog appears although I have set e.Cancel=true. The same thing happens, if I double click a Time Slot. I think e.Cancel=true should prevent showing the edit dialog?

Second thing is also not working: In the Control RadScheduler following worked:

_sView.MouseLeftButtonUp += new MouseButtonEventHandler(OnScheduler_MouseLeftButtonUp);





private void OnScheduler_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)

{

MccmAppointment selectedAppointment = _sView.SelectedAppointment as MccmAppointment;

...

}

But in Schedule View, the event Mouse Left Button Up does not fire, I i click on an Appointment. But it fires, if I click on any other UIElement. I can't figure out why?

Please help me asap!

Thanks,
Ronald

Need to show Appointments "larger" in Month View

Hi,

I would like to show appointments in Month View with a fixed height of say 50 px. I could not find the place in the schedule view's theme (I am using ScheduleView.xaml for additional design). Is there an easy way to do this?

Show/Hide RadPane

Hy all,

I tried to bind the IsPinned and the Visiblity property of the RadPane. When a user logs-in IsPinned shall be set to true and Visibility is set to Visible. On the other hand on logout IsPinned=false and Visibility=Hidden.

Unfortunately on login the Pane is not pinned?
Is there an other way to implement this?

I'm using the latest oficial release.

Creating a custom RadGridView template hangs Blend

Hi

I'm attempting to create a custom template for the RadGridView control. When I try to do this, Blend hangs. I am using the latest Q1 release of the Telerik controls, and

To reproduce the issue:

1. Create a blank wpf project in Blend
2. Drag a RadGridView onto the main window.
3. Edit a copy of the current style for the RadGridview
4. Edit the current template of this Style
5. Blend freezes.

Anyone else see this?

"Object does not match target type" error while editing radtreelistview

Hi,
I'm trying to display two datatypes in a RadTreeListView through XML. The first datatype, 'Director', with two properties: 'Name', and a property 'Function' . Function contains two properties i.e Name and FunctionType.

--------------------------------------------------------------------------------------------------

public

class Director

{

public string Name{ get; set; }

public ObservableCollection<Function > Function { get; set; }

}

public class Function

{

public string Name { get; set; }

public string FunctionType{ get; set; }

}




 

 

 

<Window.Resources>
 

 

 

<local:RadTreeListXmlDataSource x:Key="TreeSource" Source="TestData.xml" /> 
 
 
 

 

 

</Window.Resources>

 

 

 
 
 
 

 

 

  <telerik:RadTreeListView CellEditEnded="RadTreeListView1_CellEditEnded" x:Name="RadTreeListView1" RowIsExpandedChanged="RadTreeListView1_RowIsExpandedChanged" 
 
 
 

 

  AutoGenerateColumns="False" ItemsSource="{StaticResource TreeSource}"> 
 


 

 

 

  <telerik:RadTreeListView.ChildTableDefinitions> 
 


 

 

 

  <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}" /> 
 


 

 

 

  </telerik:RadTreeListView.ChildTableDefinitions> 
 


 

 

 

  <telerik:RadTreeListView.Columns> 
 


 

 

 

  <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Name" /> 
 


 

 

 

  <telerik:GridViewDataColumn DataMemberBinding="{Binding Source}" Header="Type" /> 
 


  

 

</telerik:RadTreeListView.Columns> 
 


 

 

 

</telerik:RadTreeListView> 
 







-------------------------------------------------------------------------------------------------



I was able to edit the Director's properties but when I tried to edit Function's properties i.e Funnction Name , 

I got an error saying "Object does not match target type". 

Can you please provide a sample for the above functionality?

ValuePath property?

In other products, I had a ValuePath property and Value property, which allowed me to specify
1. The property of the lookup collection to use for the identifier of the value on the data context (ValuePath)
2. The value of the item in the data context, uh, (Value)

I assume SelectedValue is the property for Value?

Is there a ValuePath property? How do I specify that StateId from a State collection bound to the radcombo is the property to use for StateId on a Address object?

Thanks,

Morgan
